| abstract |
The present invention provides novel pyrimidine nucleoside derivatives represented by the following formula (I): HN I R2 CH (CH2)n 2,X 1∩ D3 wherein R1 represents e.g. an alkyl group; RZ represents e.g. a phenyl group or a 3,5-dimethylphenyl group; and R3 represents e.g. a vinyl group or a ethynyl group; A, B and X represent e.g. oxygene atoms; Z represents e.g. a methylene group or a carbonyl group; n is e.g. 1. The compounds were found to be highly active against wild-type and mutant HIV-1. |
