December 2021 "Drug development is rarely trivial. Drugs that do make it to clinical trials have major hurdles to clear—not the least of which is safety It is necessary for drugs to evaluated for potential toxicities and side effects, and these key factors must be deemed tolerable before investigators can assess drug potency. Modern drug development approaches include a range of techniques leveraging structural biology, immunology

GPCRs continue to be regarded as one of the most tractable classes of drug targets and are targeted by 30%–40% of current drugs (Hauser et al., 2017), with annual sales of GPCR-targeting drugs in 2018 accounting Despite this high number of GPCR targeted drugs, only a small portion (∼110) of the human GPCRome (consisting of approximately 850 GPCRs) has been successfully drugged, and obtaining highly potent and selective

G-protein coupled receptors: models, mutagenesis, and drug design.

The advent of AlphaFold2 (AF2) has brought AI applications in drug development to unprecedented heights targets and designing effective drug molecules. G protein-coupled receptors (GPCRs) are major drug targets, yet their complex and dynamic structures This validates AF2's potential in enhancing drug discovery precision and efficiency. Despite its transformative potential, AI in drug development faces several challenges.

October 2022 GPCR Agonist-to-Antagonist Conversion: Enabling the Design of Nucleoside Functional Switches for the A2A Adenosine Receptor "Modulators of the G protein-coupled A2A adenosine receptor (A2AAR) have been considered promising agents to treat Parkinson's disease, inflammation, cancer, and central nervous system disorders. Herein, we demonstrate that a thiophene modification at the C8 position in the common adenine scaffold converted an A2AAR agonist into an antagonist. We synthesized and characterized a novel A2AAR antagonist, 2 (LJ-4517), with Ki = 18.3 nM. X-ray crystallographic structures of 2 in complex with two thermostabilized A2AAR constructs were solved at 2.05 and 2.80 Å resolutions. In contrast to A2AAR agonists, which simultaneously interact with both Ser2777.42 and His2787.43, 2 only transiently contacts His2787.43, which can be direct or water-mediated. The n-hexynyl group of 2 extends into an A2AAR exosite. Structural analysis revealed that the introduced thiophene modification restricted receptor conformational rearrangements required for subsequent activation. This approach can expand the repertoire of adenosine receptor antagonists that can be designed based on available agonist scaffolds." Read more at the source #DrGPCR #GPCR #IndustryNews
