The R- and S-isomers of 6'-C-neplanocin A analogues, which are all known as inhibitors of S-adenosylhomocysteine (AdoHcy) hydrolase, were studied for their inhibitory effects on Human Immunodeficiency Virus type 1 (HIV-1) replication and HIV-1 Tat-mediated transactivation. The R-isomers showed much greater activity against AdoHcy hydrolase than the S-isomers. The same differential activity was observed against the HIV-1 replication and the Tat transactivation.
