Oximes, belonging to imines with the general formula of RR'C=NOH, are produced by the nucleophilic addition reaction between hydroxylamine with ketones or aldehydes, yielding corresponding aldoxime and ketoxime. The presence of hydrogen bond acceptor and donor is the classical feature of oxime‐containing structural framework. This review presents a summary of the role of oximes and its structure activity relationships including antimicrobial, anticancer, anti‐inflammatory, antihyperglycemic, insecticidal agents, along with their involvement in the treatment of organophosphorus poisoning. The review also focused on the pharmacological profile of lead molecules of several classes of oxime‐containing compounds. [ABSTRACT FROM AUTHOR]

Catechol- O -methyltransferase (COMT) inhibitors have played a crucial role in the development of potent and selective drugs for the treatment of Parkinson's disease, depression, and anxiety disorders. This review provides a comprehensive analysis of the structure-activity relationship (SAR) of COMT inhibitors, highlighting key structural features and pharmacophoric elements that govern their potency, selectivity, and pharmacokinetic properties. This review also discusses the application of SAR principles in the design and optimization of COMT inhibitors. Our analysis reveals the emergence of novel chemical scaffolds and the potential for COMT inhibitors to address unmet medical needs in neurology and psychiatry. This Perspective serves as a valuable resource for clinicians and researchers, providing insights into the rational design of COMT inhibitors and the development of next-generation therapeutics., Competing Interests: The authors declare no competing financial interest., (© 2024 The Authors.
