Discovery of (S)-N-(3-isopropylphenyl)-2-(5-phenylthiazol-2-yl)pyrrolidine-1-carboxamide as potent and brain-penetrant TRPV1 antagonist
Eur J Med Chem 2022 Apr 5;233:114191.PMID:35263708DOI:10.1016/j.ejmech.2022.114191
Transient receptor potential vanilloid 1 (TRPV1) antagonists can inhibit the transmission of nociceptive signals from the peripheral to the central nervous system (CNS), providing a new strategy for pain relief. In this work, in order to develop potent, CNS-penetrant, and orally available TRPV1 antagonists, three series of novel molecules based on the key pharmacophore structures of classic TRPV1 ligands SB-705498 and MDR-652 were designed and synthesized. Through systematic in vitro and in vivo bioassays, (S)-N-(3-isopropylphenyl)-2-(5-phenylthiazol-2-yl)pyrrolidine-1-carboxamide (7q) was finally identified, which had enhanced TRPV1 antagonistic activity (IC50 (capsaicin) = 2.66 nM), excellent CNS penetration (brain/plasma ratio = 1.66), favorable mode-selectivity, good bioavailability, and no side effects of hyperthermia. Molecular docking and dynamics studies indicated that the high binding affinity of compound 7q to TRPV1 was related to multiple interactions, which resulted in significant conformational changes of TRPV1. Overall, our findings have led to a potent, mode-selective, and CNS-penetrant TRPV1 antagonist as a valuable lead for development of novel TRPV1 antagonists.
