The Structure-property Relationships of GPCR-targeted Drugs Approved between 2011 and 2021

초록

Background: G-protein-coupled receptors (GPCRs) are the largest family of membrane receptors and the most intensively studied drug targets. Given the physiologi-cal importance of signal transduction by GPCRs and the recent progress in the structure determination of membrane proteins, the development of GPCR antagonists and agonists is expected to continue to be a major area of medicinal chemistry research. Methods: The structure-property relationship illustrates how the modification of the chemical structure influences the absorption, distribution, metabolism, excretion, and other related properties of drug compounds. Understanding the structure-property relationships of clinically approved GPCR-targeted drugs and their analogues could provide useful information on the lead-to-candidate optimization strategies. Results: Among more than 50 GPCR antagonists and agonists approved in the last de-cade, the structure-property relationships of 17 drugs are compiled from medicinal chemistry literature, in which detailed pharmacokinetic and toxicological properties are dis-closed not only for the final drug candidate but also for key analogues generated during the lead optimization campaign. Conclusion: The structure-property relationships hereby summarized demonstrate how in vitro and in vivo properties of the membrane protein-targeted ligands could be effectively optimized, in many cases, without requiring a significant change in the molecular size. This information is expected to provide valuable insights to expedite new GPCR-tar-geted drug development. © 2023 Bentham Science Publishers.
