title: HIV protease inhibitor HOE/BAY 793, structure-activity relationships in a series of C2-symmetric diols.
abstract: A detailed structure-activity relationship of C2-symmetric diol inhibitors of HIV-1 protease leads to inhibitor 6 (HOE/BAY 793) which is outstanding in the inhibition of the enzyme and in the inhibition of viral replication in HIV infected cell culture (IC50: 0.3 nM; EC50: 3 nM). There are well defined steric requirements for the design of the side chains P1-P3 of the inhibitors. In addition, all three side chains need to be lipophilic. While the enzyme tolerates hydrophilic substituents in some cases, drastic reductions in anti-HIV activity are observed in cell culture, most likely due to insufficient cell penetration.
