Acs Med.Chem.Lett., 14:171-175, 2023 Cited by PubMed Abstract: HIV-1 protease is an important target for pharmaceutical intervention in HIV infection. Extensive structure-based drug design led to darunavir becoming a key chemotherapeutic agent. We replaced the aniline group of darunavir with a benzoxaborolone to form BOL-darunavir. This analogue has the same potency as darunavir as an inhibitor of catalysis by wild-type HIV-1 protease and, unlike darunavir, does not lose potency as an inhibitor of the common D30N variant. Moreover, BOL-darunavir is much more stable to oxidation than is a simple phenylboronic acid analogue of darunavir. X-ray crystallography revealed an extensive network of hydrogen bonds between the enzyme and benzoxaborolone moiety, including a novel direct hydrogen bond from a main-chain nitrogen to the carbonyl oxygen of the benzoxaborolone moiety that displaces a water molecule. These data highlight the utility of benzoxaborolone as a pharmacophore. PubMed: 36793428DOI: 10.1021/acsmedchemlett.2c00464 PDB entries with the same primary citation |
