Artificial intelligence (AI) is reshaping drug discovery by bridging the gap between traditional computer-aided drug design (CADD) and next-generation, data-driven methodologies. Unlike conventional CADD, which relies on physical modelling of molecular interactions, AI integrates machine learning (ML) and deep learning (DL) to leverage rapidly expanding datasets in biology and chemistry. These approaches enable efficient prediction of molecular structures, binding affinities, and pharmacological properties, thereby reducing both time and cost in drug development. The impact is particularly profound in the design of protein therapeutics, such as antibodies, which require accurate modelling of complex structures and interactions. Emerging AI frameworks, including generative adversarial networks (GANs), reinforcement learning (RL), and multi-omics integration, are accelerating target identification, optimizing lead candidates, and refining pharmacokinetic and biophysical profiles. In this review, we highlight recent advances at the interface of AI and antibody drug discovery, discuss key methodological developments, and examine the challenges that remain in translating AI-driven strategies into clinical success. We further explore how AI-enabled platforms are redefining the landscape of precision biopharmaceuticals, offering new opportunities for efficient and targeted therapeutic development.

Chemical looping hydrogen production (CLHP) is a highly efficient and low-carbon technology that enables continuous hydrogen production. It is based on the transfer of oxygen atoms between two or three reactors using an oxygen carrier as an intermediate medium to produce high-value-added syngas and high-purity hydrogen. This study begins with a brief overview of the technical principles and key advantages of methane chemical looping reforming for hydrogen production. Based on the Web of Science Core Collection database, bibliometric keyword clustering analysis was employed to identify trends in oxygen carrier materials within the chemical looping hydrogen production field, with a particular focus on progress in the modification and design of Fe-, Ni-, and Cu-based, and composite mineral oxygen carriers. Furthermore, by systematically collating previously reported density functional theory (DFT) calculation data, a comparative analysis of the differences in key thermodynamic and kinetic parameters among various oxygen carriers, including the reaction activation energy, oxygen vacancy formation energy, and adsorption energies of reactants and intermediates, was performed. Finally, the review systematically summarizes the mechanisms by which preparation methods regulate the microstructure and redox properties of oxygen carriers, aiming to provide a reference for the rational design and controlled synthesis of high-performance oxygen carriers, fill gaps in existing reviews, and offer cutting-edge systematic reference material for future research into chemical looping hydrogen production technology.

Oxazepines are seven-membered heterocyclic frames containing oxygen and nitrogen within their structure and are regarded as privileged scaffolds in medicinal chemistry. These structures constitute the parent core of several essential drugs and have numerous biological properties like antifungal, anti-inflammatory, antibacterial, antitumor, anti-HIV, and antidepressant activities. The wide biological activities of oxazepines have encouraged organic chemists to design various novel synthetic routes to synthesize new oxazepine derivatives. Though undoubtedly valuable and significant, many of these synthetic methods often involve multistep procedures that suffer from the waste generation of materials. In contrast, multicomponent reactions (MCRs) have recently emerged as sustainable synthetic tools for the synthesis of various types of oxazepines. In this regard, MCRs, especially Ugi and Betti reactions, can provide complex synthons in a straightforward and green manner for the synthesis of oxazepine derivatives. MCRs can also produce oxazepines in high yields in a single pot and a single step. The present review covers articles on the synthesis of oxazepines via MCRs from their inception to 2025. It will be beneficial for chemists to design safe, economical, and environmentally benign methods for the synthesis of diverse types of oxazepines.

Antimicrobial resistance (AMR) is a worldwide health crisis challenging existing antibiotics, leading to increased mortality. Since their discovery in the early twentieth century, antibiotics have transformed medicine and saved countless lives. But today, the worrying increase in antibiotic resistance casts a shadow over the discovery of antibiotics. The abuse and overuse of antibiotics has led to the unrelenting adaptability of microbes, which is the cause of this global issue. With particular attention on ciprofloxacin (CIP), 2nd generation fluoroquinolones work by preventing DNA gyrase and topoisomerase IV from performing their vital functions, which include transcription, recombination, replication, and condensed DNA remodeling. Numerous researchers have developed CIP derivatives that are promising treatments, but factors such as overuse, multiple drug therapy, and misuse contribute to widespread resistance along with different side effects. So, to overcome such problems, diverse strategies to enhance CIP efficacy are examined, including synthetic approaches such as hybridization, Mannich reaction, and oxidation, aiming to modify the structure of CIP and create novel compounds with potentially enhanced biological activities, improved efficacy, or reduced side effects, which happens as a result of chemical and physical changes, typically involving one or more reactions. Along with this, nanotechnology for drug delivery and synergistic combinations with aminoglycosides, tobramycin, or azithromycin, antimicrobial peptides (AMPs) and monoclonal antibodies (mAbs) offer potential to combat multidrug-resistant strains. This review provides insights into potential breakthroughs necessary to overcome AMR challenges and advance effective emerging synthetic and delivery approaches for antibacterial treatments. Overall, we have compiled different emerging strategies to develop CIP derivatives with the aim of discovering new and more effective ways to combat drug-resistant infections.

Nitrate esters, also known as organic nitrates, are an important class of compounds owing to their diverse applications in synthetic chemistry, medicine, and materials science. Traditionally recognized as energetic materials and vasodilators, they have also demonstrated therapeutic potential in pain management, wound healing, and cancer treatment. The synthesis of nitrate esters via C-H functionalization enables direct access to valuable products from simple hydrocarbons. Recent advances in C(sp)-H functionalization methods have facilitated their formation using various nitrate sources, including HNO, t-BuONO, metal nitrites, metal nitrates, and hypervalent iodine reagents. However, existing methodologies are largely restricted to a limited substrate scope, primarily targeting methyl arenes, ethyl carbonyls, 1,3-dicarbonyls, and protected alcohols. This limitation presents a clear opportunity for expanding the range of applicable starting materials. This review summarizes current synthetic strategies for nitrate esters formation through C(sp)-H functionalization and highlights the potential of these approaches to access previously unattainable nitrate esters.

Chromanes are privileged scaffolds in medicinal chemistry because they exhibit diverse biological activities. Their stereoselective synthesis has become a critical objective in drug development. The emergence of organocatalysis has sparked a paradigm shift in synthetic chemistry by offering a highly selective alternative to traditional metal-catalyzed reactions. This review discusses the transformative impact of organocatalyzed reactions on the asymmetric synthesis of chromane derivatives, focusing on key classes of catalysts such as chiral phosphoric acid, chiral amines, bifunctional systems, and others reported since 2020. Organocatalysis not only achieves high levels of stereocontrol but also adheres to the principles of green chemistry by eliminating toxic metals and enabling mild reaction conditions. These advancements diversify synthetic methodologies and establish organocatalysis as a fundamental approach in the sustainable synthesis of bioactive chromanes.

In the past decade, asymmetric catalysis has undergone significant advances, driven by the development of chiral phosphoric acids, transition metal complexes, and photoredox catalytic systems. Among these, asymmetric multicomponent reactions (AMCRs) have emerged as powerful tools for the rapid and selective construction of structurally complex molecules. This research highlights recent progress (2019-2025) in AMCRs from the perspectives of these three key catalytic platforms, emphasizing their distinct and cooperative roles in enabling enantioselective bond formation. Particular emphasis is placed on AMCRs catalyzed by chiral phosphoric acids, photoredox systems, and Lewis acids and bases, alongside representative transition metal-catalyzed AMCRs. These are discussed as discrete yet interconnected catalytic manifolds, providing a balanced and comprehensive overview of the field. Mechanistic features, including catalyst interplay, activation modes, and stereocontrol elements, are critically analyzed to establish a unified understanding of reactivity and selectivity. By focusing on these well-defined catalytic domains, this manuscript delineates the fundamental principles that underpin modern AMCR design and highlights emerging strategies that integrate light-driven processes with chiral induction. Collectively, these advances underscore the evolution of asymmetric catalysis into a cohesive and versatile platform for the efficient synthesis of functionally and structurally sophisticated molecules.

Curcumin, a polyphenolic compound from Curcuma longa, has many biological effects, including antioxidant, anti-inflammatory, anticancer, and neuroprotective properties. However, its use in food, pharmaceutical, and biomedical systems is limited owing to poor water solubility, chemical instability, fast metabolism, and very low oral bioavailability. To address these issues, various formulation strategies have been created. Microencapsulation is one of the most effective methods for improving the stability, bioaccessibility, and controlled release of curcumin. At the same time, computational tools such as molecular docking and molecular dynamics simulations have become more important for understanding curcumin-carrier interactions and predicting formulation stability at the molecular level. Although both experimental encapsulation techniques and in silico modeling are well-established, research in these areas often occurs separately, leading to fragmented understanding of curcumin delivery systems. This review offers a detailed analysis of curcumin research by connecting its physicochemical properties and degradation pathways with microencapsulation strategies and computational modeling. Key encapsulation techniques such as spray drying, ionotropic gelation, complex coacervation, and nanostructured delivery systems are examined in terms of their mechanisms, benefits, drawbacks, and uses. Additionally, recent progress in molecular docking and molecular dynamics simulations is discussed to emphasize their growing role in helping choose carriers and design formulations. By linking formulation science with predictions at the molecular level, this review presents a framework to promote the development of effective, stable, and bioavailable curcumin-based delivery systems for food, pharmaceutical, and biomedical purposes.

Rare-earth high-entropy oxides (RE-HEOs) represent a distinct class of entropy-stabilized ceramics in which multiple lanthanide cations occupy a common crystallographic sublattice, generating strong chemical disorder, lattice distortion, and complex defect landscapes. Unlike transition-metal-based high-entropy oxides, RE-HEOs are governed by localized 4f electronic states, weak crystal-field coupling, and variable redox chemistry, leading to emergent structural, electronic, magnetic, and optical phenomena that challenge conventional solid-state descriptions. This review provides a physics-oriented analysis of RE-HEOs, focusing on the thermodynamic foundations of configurational entropy stabilization, the interplay between enthalpy, entropy, and kinetic trapping, and the consequences of severe chemical disorder for crystal structure and phase stability. We review how lattice distortion, oxygen vacancy disorder, and cation randomness modify phonon spectra, ionic transport pathways, and electronic structures, with particular emphasis on the role of localized 4f states, defect-induced in-gap levels, and disorder-broadened excitation spectra. Spectroscopic manifestations of disorder including crystal-field relaxation, line broadening, lifetime modification, and energy transfer processes are discussed within a unified framework linking local symmetry breaking to macroscopic response. We further discuss the optoelectronic properties of RE-HEOs, including photoluminescence from intra-4f transitions, upconversion mechanisms, and disorder-induced modifications of radiative lifetimes and quantum efficiency. The application landscape spans both energy conversion (electrocatalysis, solid oxide fuel cells, thermal barrier coatings) and optoelectronic technologies (phosphors, scintillators, optical thermometry, and anti-counterfeiting). Likewise, we assess theoretical and computational approaches, including density functional theory with strong correlation corrections, statistical thermodynamics, and emerging machine-learning models, highlighting their ability and current limitations in capturing disorder-driven physics in multi-component oxides. Finally, we identify open questions central to condensed-matter physics, including the nature of entropy-stabilized metastability, the limits of band theoretical descriptions in highly disordered 4f systems, and the role of configurational entropy in tuning electron-phonon and defect interactions. By consolidating experimental and theoretical insights, this review establishes RE-HEOs as a platform for exploring disorder-dominated solid-state physics beyond conventional crystalline oxides.

Covalent organic frameworks (COFs) are crystalline, porous polymers with tunable architectures, high surface areas, and robust chemical stability, making them promising platforms for chemical sensing. This review surveys recent advances in luminescent COFs (LCOFs) for the selective detection of hazardous contaminants via fluorescence-based mechanisms, including photo-induced electron transfer and energy transfer. Representative studies discuss ultra-low detection limits for UO, Hg, and Pb, along with rapid response times, high adsorption capacities, and strong recyclability. Sensitivity and selectivity are further enhanced through functionalization strategies such as amidoxime grafting, lanthanide incorporation, and linkage engineering. Beyond actinide sensing, LCOFs have demonstrated effectiveness toward mercury, lead, nitro-aromatic explosives, and biological markers, underscoring their functional versatility. Despite these advances, key challenges persist, including scalable synthesis, structural stability in complex matrices, and integration into deployable sensing devices. Future progress leveraging hybrid material systems, computation-guided design, and portable detection platforms could position LCOFs as transformative tools for environmental monitoring, nuclear safety, and public health protection.

Lithium-ion batteries (LIBs) are the key technology that allows the adoption of electric vehicles (EVs) and integration of renewable energy, but their development faces a complex of technical, environmental, and policy issues that require a multidimensional analysis. This review critically evaluates electrochemical activities, structural innovations, environmental effects, and regulatory frameworks used to deploy LIBs in EVs to inform the current development strategies. A narrative literature review was conducted across Google Scholar, ScienceDirect, Web of science, IEEE Xplore, ACS, and Scopus where peer-reviewed articles, technical reports, and policy documents published between 2015 and 2025 were searched. Thematic synthesis melded discoveries in electrochemical processes, materials science, and policy space. LIBs have a better energy density (130-275 Wh kg) and life- cycle greenhouse gas emission reductions of 46-52% compared to internal combustion engines with manufacturing emission (5075 kg CO-eq) payback within 1.5-3 years of average driving. Major industrial innovation includes high-nickel cathodes, e.g., NMC811 and NCA, allow EV ranges of 400-500 km, silicon-graphite composite anodes with up to 550-650 mAh g capacity, and cell-to-pack designs. These innovations have been commercialized by CATL and BYD (Build Your Dreams) and raise cell-level energy density by 10-15% via removal of module-level components. The regulatory frameworks in the EU, US, and China are analyzed as the sources of market growth and the shift in the circular economy. The review finds that steady electrification must have an integrated policy to cover supply-chain equity, set chemistry-independent performance standards, and facilitated commercialization routes to solid-state and sodium-ion technologies that will characterize the post-lithium-ion phase.

Doxorubicin is an anthracycline-class medication with a broad spectrum of antitumor activity, although significant adverse cardiac toxicity limits its use. This dictates the need for its encapsulation in drug delivery systems, as nanoparticles can eliminate cardiac toxicity and enhance tumor uptake. This review focuses on advances in inorganic/polymeric nanocarrier engineering that can (1) provide sites for doxorubicin immobilization, (2) ensure colloidal stability, and (3) allow multifunctional capabilities for synergistic cancer treatment. Focusing mainly on polymeric and polymer-capped inorganic nanomaterials owing to their high control over composition, we describe approaches to obtain nanoparticles for synergistic chemotherapy using doxorubicin in combination with magnetic hyperthermia, photothermal, and photodynamic cancer therapies. In addition, the review outlines selected chemical routes for the synthesis of the macromolecules required for efficient doxorubicin incorporation. The prospects for the use of doxorubicin carriers as theranostics described in this review underscore the need for innovation in carrier design for efficient cancer therapy.

Cross dehydrogenative coupling (CDC) via C-H bond activation enables direct and sustainable synthesis of carbon-carbon and carbon-heteroatom bonds, bypassing the requirement of prefunctionalization steps. Utilizing earth-abundant metals such as iron (Fe), cobalt (Co), nickel (Ni), and copper (Cu), CDC offers cost-effective, environmentally friendly alternatives to precious metal catalysts (Ru, Rh, Pd, Ir). These metals facilitate mild and efficient C-H activation, expanding substrate scope and improving selectivity. Among different methods, transition metal-catalyzed C-H activation via CDC has emerged as an effective tool for direct functionalization, offering efficiency, sustainability, and regioselectivity. Recent advancements address challenges such as catalyst deactivation and functional group compatibility. This article highlights recent developments of various synthetic alkylation, alkenylation, and alkynylation strategies of arenes and their mechanistic pathways catalyzed by earth-abundant metals (Fe, Co, Ni, and Cu) through cross dehydrogenative coupling via C-H bond activation.

Graphitic carbon nitride (g-CN) is a nonmetalic semiconductor photocatalytic material that has attracted widespread attention in the field of photocatalysis owing to its advantages, including abundant raw material sources, environmental friendliness, good cyclic stability, and ease of structural control. Currently, various methods are available for its preparation, including thermal polymerization, template-assisted synthesis, solvothermal synthesis, and chemical vapor deposition. By adjusting parameters such as pyrolysis temperature and time, the morphology of g-CN can be effectively controlled. However, pure g-CN still faces challenges, including high carrier recombination rates and limited utilization of visible light, resulting in relatively low photocatalytic activity. To overcome these limitations, various modification strategies have been studied extensively and analyzed the pathways for source modification on the basis of this mechanism. It outlines mainstream preparation methods and recent advances in modification research, evaluating the strengths and limitations of different strategies. Drawing on recent case studies, this discussion examines the advantages and constraints of various synthesis approaches, and links modification strategies to their respective application fields. Finally, future research directions for enhancing photocatalytic performance are proposed, aiming to provide theoretical insights and technical support for further research and practical applications of this material in photocatalysis.

C-N/N-N atropisomers constitute pivotal structural elements in privileged scaffolds of natural products, bioactive compounds, chiral ligands, and advanced functional materials. With these wide-ranging utilities, the construction of these axially chiral frameworks has garnered increasing attention from chemists. This review highlights asymmetric annulation as a powerful and efficient strategy to construct such scaffolds, enabling simultaneous aromatic ring formation and axial chirality control in a single step. Recent advances up to August 2025 are summarized, covering both transition metal catalysis (eg., palladium, rhodium, copper, cobalt with chiral ligands) and organocatalysis (e.g., chiral phosphoric acids and N-heterocyclic carbenes). Key methodologies include [4 + 2] cyclizations, ynamide annulations, C-H activation, and annulations involving acroleins or aminocarbonyls, offering versatile routes to diverse C-N and N-N atropisomers with high enantioselectivity. This work provides an integration of catalytic systems previously reviewed in isolation, underscoring the progress in synthetic efficiency and catalytic system diversity.
