What is Synthesis and evaluation of A-seco type triterpenoids for anti-HIV-1protease activity about?
2,3-Seco-dioic acids derived from four different triterpene skeletons were prepared and evaluated for their anti-HIV-1 protease activity. Two A-seco derivatives showed potent inhibitory activity against HIV-1 protease (3c and 3e, IC(50) 5.7 and 3.9 microM, respectively), while four other derivatives showed moderate to weak inhibition (3a, 3b, 3d and 3f, IC(50) 15.7-88.1 microM). The combination of a 2,3-seco-2,3-dioic acid functional group in ring A and a free acid group at C-28 or C-30 significantly enhanced HIV-1 protease inhibitory activity (3a, 3c-3e, IC(50) 3.9-17.6 microM). On the other hand, all A-seco derivatives were found to be very weak inhibitors of HCV, renin and trypsin proteases (IC(50)>80 microM). These findings indicate that A-seco triterpenes with a carboxyl group at C-28 or C-30 are novel and highly selective HIV-1 protease inhibitors.
