Combination of Non-natural d-Amino Acid Derivatives and Allophenylnorstatine− Dimethylthioproline Scaffold in HIV Protease Inhibitors Have High Efficacy in Mutant …
Several non-natural d-amino acid derivatives were introduced as P2/P3 residues in allophenylnorstatine-containing (Apns;(2 S, 3 S)-3-amino-2-hydroxy-4-phenylbutyric acid) HIV protease inhibitors. The synthetic analogues exhibited potent inhibitory activity against HIV-1 protease enzyme and HIV-1 replication in MT-4 cells. Structure–activity relationships revealed that d-cysteine or serine derivatives contributed to highly potent anti-HIV ...
