One of the most reliable measures for controlling postprandial hyperglycemia is to reduce the glucose level by inhibiting enzymes in the digestive system, such as Alpha-Glucosidase and Alpha-Amylase. Here, we have investigated the use of inhibitors to inhibit carbohydrate metabolism in order to restrict glucose levels in diabetic patients. Acarbose, Voglibose, and Miglitol are three inhibitors approved by the FDA that efficiently inhibit these two enzymes and thereby minimising hyperglycemia but are al-so significantly helpful in reducing the risk of cardiovascular effects. We also provide insight into the other known inhibitors currently available in the market. The adverse effects associated with other inhibitors emphasise the demand for the latest in silico screening and in vitro validation in the development of potent inhibitors with greater efficacy and safety for the treatment of Type 2 diabetes. The recent findings suggest that Alpha-Glucosidase and Alpha-Amylase play a major role in carbohydrate metabolism and triggering the increase in glucose levels. This review pro-vides the latest scientific literature findings related to these two enzymes as well as the role of primary and secondary inhibitors as potential candidates. Moreover, this review elaborates the framework on the mechanism of action, different plant sources of extraction of these enzymes, as well as kinetic assay of inhibitors and their interaction that can be used in future prospects to de-velop potential leads to combat Type 2 diabetes.

Efforts are being putto identify promising targets, particularly small non-coding nucleotide sequences, which can lead to new treatments for this disease. The discovery of significant mutations that contribute to the development of colorectal tumors is a major step in the advancement of molecular oncology, as these mutations give rise to heterogeneous tumors that differ in their origin. These mutations play a significant role in the progression of the disease and are now being targeted for treatment. The prognosis for a disease is influenced by the patient's sensitivity to antitumor therapy. However, new approaches to finding effective targets for antitumor treatments face new fundamental challenges due to clinical issues. These issues include the epigenetic regulation of markers of oncogenesis, which allows for the development of new therapeutic strategies. RNA interference, in particular, has been linked to non-copying RNA sequences such as microRNAs. These microRNAs are associated with certain processes that can influence all aspects of oncogenesis. The diversity of microRNAs allows for a differentiated approach when treating tumors in various locations.

Tumors can form when CDK6, a gene essential for controlling cell growth, isn't working correctly. Researchers are investigating drugs that inhibit CDK6; some of them appear promising. Nevertheless, CDK6 is advantageous and harmful to cancer because it controls other cellular processes. By inhibiting CDK6 and CDK4, CDK4/6 inhibitors offer a novel therapeutic strategy that stops cell proliferation. The study investigates the function of CDK6 in cancer, the difficulties in targeting CDK6, and possible remedies. OBJECTIVE: Scientists have developed drugs designed to block CDK6 and prevent it from altering other proteins. These drugs, also known as CDK6 inhibitors, help treat cancer. Finding the best drugs for CDK6 is still tricky, though. The drugs' selectivity, potency, and cost are some difficulties. These factors depend on CDK6's structure and interactions with other proteins. The structure of CDK6 and how it influences its function and regulation are explained in this review. It also describes CDK6's function in cancer and its interaction with other molecules and proteins, which is crucial for cell division. This review also discusses the present and upcoming therapies that target CDK6, as well as how CDK6 interacts with drugs that block it. CONCLUSION: This review presents the structure, current research, and overview of CDK6. It also reviews the role of CDK6 in cancer, function, and regulation. Additionally, it explores its role in cancer signaling networks and its interaction with CDK6 inhibitors. Lastly, it discusses the current status and prospects of therapies targeting CDK6.

Represe...Alzheimer's disease (AD) is a debilitating neurodegenerative disorder characterized by the presence of amyloid-β (Aβ) plaques and tau-containing neurofibrillary tangles, leading to cognitive and physical decline. Representing the majority of dementia cases, AD poses a significant burden on healthcare systems globally, with onset typically occurring after the age of 65. While most cases are sporadic, about 10% exhibit autosomal forms associated with specific gene mutations. Neurofibrillary tangles and Aβ plaques formed by misfolded tau proteins and Aβ peptides contribute to neuronal damage and cognitive impairment. Currently, approved drugs, such as acetylcholinesterase inhibitors and N-methyl D-aspartate receptor agonists, offer only partial symptomatic relief without altering disease progression. A promising development is using lecanemab, a humanized IgG1 monoclonal antibody, as an immune therapeutic approach. Lecanemab demonstrates selectivity for polymorphic Aβ variants and binds to large soluble Aβ aggregates, providing a potential avenue for targeted treatment. This shift in understanding the role of the adaptive immune response in AD pathogenesis opens new possibilities for therapeutic interventions aiming to address the disease's intricate mechanisms. This review aims to summarize recent advancements in understanding Alzheimer's disease pathophysiology and innovative therapeutic approaches, providing valuable insights for both researchers and clinicians.

Looking at these enormous potentials, researchers have explored how they can be used to manage numerous cancers. It's been studied for cancer management due to its anti-angiogenesis, anti-metastatic, and antiproliferative mechanisms. Despite having these proven pharmacological activities, the clinical use of quercetin is limited due to its first-- pass metabolism, poor solubility, and bioavailability. To address these shortcomings, researchers have fabricated various nanocarriers-based formulations to fight cancer. The present review overshadows the pharmacological potential, mechanisms, and application of nanoformulations against different cancers. Teaser: Explore the potential of Quercetin, a natural flavonoid with diverse pharmacological activities, and its nanoformulations in managing various cancers.

A...Neglected diseases are a group of infectious diseases, many of them parasitic, that mainly affect the poorest populations with limited access to health services, especially those living in remote rural areas and slums. According to the World Health Organization (WHO), neglected diseases put the lives of more than 200 million people at risk, and treatment is made difficult by the occurrence of resistance to existing medications, as well as the high level of toxicity. In this way, the potential of multitarget compounds is highlighted, defined as compounds designed to modulate multiple targets of relevance to disease, with the overall goal of enhancing efficacy and/or improving safety. Thus, the objective of our study is to evaluate existing multitarget compound approaches for neglected diseases, with an emphasis on Leishmaniasis, Chagas Disease, and Arboviruses. A literature review was performed by searching the database "Web of Sciences". In relation to the diseases covered in this work, Leishmaniasis, individually, was the one that presented the largest number of articles (11) that dealt with the topic, which can be justified by the high prevalence of this disease in the world, the second most common disease was Dengue, followed by Chagas disease, Chikungunya virus, and Zika virus. Furthermore, the multitarget potential of phenolic compounds was observed in all diseases under study, with the mechanisms related to the nucleus and transcription being the most reported mechanisms. From this perspective, it is worth highlighting the effectiveness of approaches related to multitarget drugs in discovering new therapeutic agents for neglected diseases.

Over the past few years, there has been considerable interest in nanotechnology due to its potential utility in creating drug-delivery systems designed to combat this illness. The primary aim of these devices is to enhance the delivery of targeted medications, optimise the specific cells that receive the drugs, tackle treatment resistance in malignant cells, and introduce novel strategies for preventing and controlling diseases. This research aims to examine the methodologies utilised by various carrier nanoparticles in the context of therapeutic interventions for breast cancer. The main objective is to investigate the potential application of novel delivery technologies to attain timely and efficient diagnosis and treatment. Current cancer research predominantly examines diverse drug delivery methodologies for chemotherapeutic agents. These methodologies encompass the development of hydrogels, micelles, exosomes, and similar compounds. This research aims to analyse the attributes, intricacies, notable advancements, and practical applications of the system in clinical settings. Despite the demonstrated efficacy of these methodologies, an apparent discrepancy can be observed between the progress made in developing innovative therapeutic approaches and their widespread implementation in clinical settings. It is critical to establish a robust correlation between these two variables to enhance the effectiveness of medication delivery systems based on nanotechnology in the context of breast cancer treatment.

Monotherapy can lead to resistance and side effects. Multi-target drug discovery is gaining importance as data on bioactivity becomes more abundant. The design of multi-target drugs is expected to be an important development in the pharmaceutical industry in the near future. This review presents multi-target compounds against trypanosomatid parasites () and tuberculosis (), which mainly affect populations in socioeconomically unfavorable conditions. The article analyzes the studies, including their chemical structures, viral strains, and molecular docking studies, when available. The objective of this review is to establish a foundation for designing new multi-target inhibitors for these diseases.

Many initiatives have been taken to detect, diagnose, and image mitochondrial abnormalities, and to transport and accumulate medicines precisely to mitochondria, all because of special mitochondrial aspects of the pathophysiology of cancer. In addition to the negative membrane potential and paradoxical mitochondrial dynamics, they include high temperatures, high levels of reactive oxygen species, high levels of glutathione, and high temperatures. Neurodegenerative diseases represent a broad spectrum of debilitating illnesses. They are linked to the loss of certain groups of neurons based on an individual's physiology or anatomy. The mitochondria in a cell are generally accepted as the authority with respect to ATP production. Disruption of this system is linked to several cellular physiological issues. The development of neurodegenerative disorders has been linked to mitochondrial malfunction, according to pathophysiological studies. There seems to be substantial evidence connecting mitochondrial dysfunction and oxidative stress to the development of neurodegenerative disorders. It has been extensively observed that mitochondrial malfunction triggers autophagy, which plays a role in neurodegenerative disorders. In addition, excitotoxicity and mitochondrial dysfunction have been linked to the development of neurodegenerative disorders. The pathophysiology of neurodegenerative illnesses has been linked to increased apoptosis and necrosis, as well as mitochondrial malfunction. A variety of synthetic and natural treatments have shown efficacy in treating neurodegenerative illnesses caused by mitochondrial failure. Neurodegenerative illnesses can be effectively treated with existing drugs that target mitochondria, although their precise formulations are poorly understood. Therefore, there is an immediate need to focus on creating drug delivery methods specifically targeted at mitochondria in the treatment and diagnosis of neurodegenerative disorders.

Recent years h...Arthritis, a prevalent inflammatory joint condition, presents challenges for effective therapeutic interventions, with conventional treatments often limited in efficacy and associated with adverse effects. Recent years have witnessed a growing interest in exploring natural compounds, particularly phytoconstituents, renowned for their anti-inflammatory and joint-protective properties. This review aims to illuminate the potential of employing nanotherapeutic approaches with phytoconstituents for enhanced arthritis management. The integration of nanotechnology with phytoconstituents emerges as a promising strategy, addressing limitations in traditional arthritis treatments. Nanocarriers like liposomes and nanoparticles provide a platform for targeted drug delivery, improving the bioavailability of phytoconstituents. Furthermore, the combined effects of phytoconstituents can be leveraged to target multiple pathways in arthritis pathogenesis, including inflammation, oxidative stress, and cartilage degradation. Key phytoconstituents, such as curcumin, resveratrol, and quercetin, exhibit anti-inflammatory and immunomodulatory properties. Nevertheless, their therapeutic potential is often impeded by challenges like poor solubility, stability, and bioavailability. Nanocarriers offer solutions by enhancing pharmacokinetics and enabling sustained release, thereby boosting overall therapeutic efficacy. The review explores the mechanisms underlying the anti-arthritic effects of phytoconstituents and their nanoformulations, including the modulation of pro-inflammatory cytokines, inhibition of matrix metalloproteinases, and reduction of oxidative stress. In summary, the integration of phytoconstituents with nanotechnology presents a promising avenue for developing targeted and effective arthritis therapies. This comprehensive review serves as a valuable resource for researchers, clinicians, and pharmaceutical developers seeking innovative approaches to address the intricate challenges associated with arthritis management.

Many strategies ha...The increasing demand for novel antitubercular agents has been the main 'force' of many TB research efforts due to the uncontrolled growing number of drug-resistant strains of in the clinical setting. Many strategies have been employed to address the drug-resistant issue, including a trend that is gaining attention, which is the design and discovery of inhibitors that are either dual- or multitargeting. The multiple-target design concept is not new in medicinal chemistry. With a growing number of newly discovered proteins, numerous targets are now available for developing new biochemical/cell-based assays and computer-aided drug design (CADD) protocols. To describe the achievements and overarching picture of this field in anti- infective drug discovery, we provide in this review small molecules that exhibit profound inhibitory activity against the tubercle bacilli and are identified to trace two or more targets. This review also presents emerging design methodologies for developing new anti-TB agents, particularly tailored to structure-based CADD.

Despite its self-limited character, more than 60% of patients have chronic recurrent arthralgia with debilitating pain that lasts for years. AIM: The objective of this review was to gather and analyze evidence from the literature on potential therapeutic strategies with molecules from natural products for the treatment of Chikungunya fever. METHODS: A search was performed for clinical trials, observational studies, or , without restriction of the year of publication or language in electronic databases (Medline/PubMed, EMBASE, Google Scholar, The Cochrane Library, LILACS (BVS), clinical trial registries (Clinical Trials.gov), digital libraries from CAPES theses and dissertations (Coordenação de Aperfeiçoamento de Pessoal de Nível Superior, Brazil) and conference abstracts. A quality assessment of the selected studies was performed using the SYRCLE, RoB2 and SciRAP tools. RESULTS: 42 studies were included, which showed molecules with potential antiviral pharmacological activity or with activity in reducing the joint complications caused by CHIKV infection. CONCLUSIONS: Among the molecules found in the survey of references, regarding the class of secondary metabolites, flavonoids stood out and for this reason, the molecules may be promising candidates for future clinical trials. Overall, evidence from studies was of acceptable quality; and intervention studies showed a high risk of bias, which is a limitation of these studies.

Recent studies have shown that abnormal expression or dysfunction of GPR56 is closely associated with many physiological and pathological processes, including brain development, neuropsychiatric disorders, cardiovascular diseases and cancer progression. In addition, GPR56 has been proven to enhance the susceptibility of some antipsychotics and anticarcinogens in response to the treatment of neuropsychological diseases and cancer. Although there have been some reports about the functions of GPR56, the underlying mechanisms implicated in these diseases have not been clarified thoroughly, especially in depression and epilepsy. Therefore, in this review, we described the molecular structure and signal transduction pathway of GPR56 and carried out a comprehensive summary of GPR56's function in the development of psychiatric disorders and cancer. Our review showed that GPR56 deficiency led to depressive-like behaviors and an increase in resistance to antipsychotic treatment. In contrast, the upregulation of GPR56 contributed to tumor cell proliferation and metastasis in malignant diseases such as glioblastoma, colorectal cancer, and ovarian cancer. Moreover, we elucidated specific signaling pathways downstream of GPR56 related to the pathogenesis of these diseases. In summary, our review provides compelling arguments for an attractive therapeutic target of GPR56 in improving the therapeutic efficiency for patients suffering from psychiatric disorders and cancer.

Oxidative stress, which is defined by an excessive amount of reactive oxygen species (ROS) production, increased exposure to external stress, and an excessive amount of the cellular defense system against them, results in cellular damage. Increased DNA damage is one of the main causes of genomic instability, and genetic changes are an underlying factor in the emergence of cancer. Through covalent connections with DNA and proteins, quercetin has been demonstrated to offer protection against the creation of oxidative DNA damage. It has been found that quercetin shields DNA from possible oxidative stress-related harm by reducing the production of ROS. Therefore, Quercetin helps to lessen DNA damage and improve the ability of DNA repair mechanisms. This review mainly focuses on the role of quercetin in repairing DNA damage and compensating for drug resistance in diabetic patients. Data on the target topic was obtained from major scientific databases, including SpringerLink, Web of Science, Google Scholar, Medline Plus, PubMed, Science Direct, and Elsevier. In preclinical studies, quercetin guards against DNA deterioration by regulating the degree of lipid peroxidation and enhancing the antioxidant defense system. By reactivating antioxidant enzymes, decreasing ROS levels, and decreasing the levels of 8-hydroxydeoxyguanosine, Quercetin protects DNA from oxidative damage. In clinical studies, it was found that quercetin supplementation was related to increased antioxidant capacity and decreased risk of type 2 diabetes mellitus in the experimental group as compared to the placebo group. It is concluded that quercetin has a significant role in DNA repair in order to overcome drug resistance in diabetes.

This comprehensive review focuses on two prominent variants of interest (VoI), XBB. 1.5 (Kraken) and XBB.1.16 ("Arcturus"), along with seven variants under observation (VuM), including EG.5. The World Health Organization (WHO) identified these variants in July 2023, highlighting EG.5's noteworthy rise in prevalence. EG.5, also known as "Eris," has exhibited an increased effective reproductive rate, prompting concerns about its contagiousness and immune evasion capabilities. With an altered spike protein in the Receptor-Binding Domain (RBD), EG.5 shares similarities with XBB.1.5 but surpasses it in prevalence, constituting 20% of COVID-19 cases in the United States by late August. EG.5's subvariant, EG.5.1, poses challenges with mutations like Q52H and F456L, contributing to its ability to bypass neutralizing antibodies. The global distribution of SARS-CoV-2 variants presents a dynamic landscape, with XBB.1.16 and other strains gaining prominence. The advent of the BA.2.86 variant further complicates the scenario, with its notable spread in regions lacking robust viral surveillance. A thorough analysis of mutations reveals the evolving nature of the Omicron variant, with distinct amino acid changes characterizing XBB.1.5, XBB.1.16, and EG.5. The WHO designates EG.5 as a "variant of interest" due to its increased contagiousness and potential immune evasion, emphasizing the need for vigilant monitoring. The risk assessment of EG.5 underscores its rapid development and growing prevalence globally. While booster vaccines targeting XBB.1.5 are in development, antiviral medications like nirmatrelvir/ritonavir (Paxlovid) continue to exhibit efficacy. In the context of the evolving variants, the FDA has granted emergency use authorization for updated COVID-19 vaccines targeting circulating strains, reflecting the adaptability of vaccination strategies to address emerging challenges. This comprehensive overview provides a nuanced understanding of the diverse Omicron subvariants, their global impact, and the ongoing efforts to combat their spread through vaccination and therapeutic interventions.

Due to the broad spectrum of lung cancer, conventional therapies including chemotherapy, radiotherapy, and surgeries, are not always effective and can have adverse consequences. The present study's overarching objective was to enhance the development of a personalized vaccine for targeted lung cancer therapy. Vaccination functions by eliciting a strong and targeted immune response defense by taking advantage of the specific antigens that are expressed by lung cancer cells. Crucial antigens associated with tumor cells have been identified with the recognition of the genetic and immunological circumstances of lung cancer in this review. The vaccine includes these antigens to prime the immune system, directing it toward recognizing and attacking cancerous cells. In this review, we have addressed the possible benefits of a targeted vaccine strategy, which include a reduction in off-target effects and an improvement in health outcomes for patients. These studies highlight the promise of a tailored vaccine in a novel way for the treatment of lung cancer. The integration of molecular profiling and immunological insights offers a rationale for the design and implementation of personalized vaccines. While challenges exist, the promise of improved treatment outcomes and reduced side effects positions targeted vaccine therapy as a compelling avenue for advancing lung cancer treatment.

The current review article highlights the involvement of ferroptosis in traumatic brain injury, acute kidney damage, ethanol-induced liver injury, and PM2.5-induced lung injury. Melatonin, a molecule produced by the pineal gland and many other organs, is well known for its anti- aging, anti-inflammatory, and anticancer properties and is used in the treatment of different diseases. Melatonin's ability to activate anti-ferroptosis pathways including sirtuin (SIRT)6/p- nuclear factor erythroid 2-related factor 2 (Nrf2), Nrf2/ antioxidant responsive element (ARE)/ heme oxygenase (HO-1)/SLC7A11/glutathione peroxidase (GPX4)/ prostaglandin-endoperoxide synthase 2 (PTGS2), extracellular signal-regulated kinase (ERK)/Nrf2, ferroportin (FPN), Hippo/ Yes-associated protein (YAP), Phosphoinositide 3-kinase (PI3K)/ protein kinase B (AKT)/ mammalian target of rapamycin (mTOR) and SIRT6/ nuclear receptor coactivator 4 (NCOA4)/ ferritin heavy chain 1 (FTH1) signaling pathways suggests that it could serve as a valuable therapeutic agent for preventing cell death associated with ferroptosis in various diseases. Further research is needed to fully understand the precise mechanisms by which melatonin regulates ferroptosis and its potential as a therapeutic target.

PDDS offers immediate delivery of medication to the respiratory system, providing advantages, such as sustained regional drug concentration, tunable drug release, extended duration of action, and enhanced patient compliance. IND, renowned for its non-invasive nature and swift onset of action, presents a promising path for advancement. Modern PDDS and IND utilize various polymers, among which chitosan (CS) stands out. CS is a biocompatible and biodegradable polysaccharide with unique physicochemical properties, making it well-suited for medical and pharmaceutical applications. The multiple positively charged amino groups present in CS facilitate its interaction with negatively charged mucous membranes, allowing CS to adsorb easily onto the mucosal surface. In addition, CS-based nanocarriers have been an important topic of research. Polymeric Nanoparticles (NPs), liposomes, dendrimers, microspheres, nanoemulsions, Solid Lipid Nanoparticles (SLNs), carbon nanotubes, and modified effective targeting systems compete as important ways of increasing pulmonary drug delivery with chitosan. This review covers the latest findings on CS-based nanocarriers and their applications.
