Synthesis and anti-HIV activity of different sugar-modified pyrimidine and purine nucleosides
摘要:
A series of base-modified pyrimidine 3'-azido-2',3'-dideoxynucleosides and 3'-substituted purine and pyrimidine 2',3'-dideoxynucleosides have been synthesized and evaluated for their inhibitory activity against human immunodeficiency virus (HIV) replication in MT-4 cells. The following pyrimidine derivatives emerged as the most potent and/or selective inhibitors of HIV-induced cytopathogenicity (in order of decreasing selectivity: 3'-azido-3'-deoxythymidine (AZT), 3'-azido-2',3'-dideoxyuridine (AzddUrd), 3'-azido-2',3'-dideoxy-5-methylcytidine (AzddMeCyd), 3'-fluoro-ddUrd (FddUrd), 3'-fluoro-ddThd (FddThd), the N4-hydroxylated derivative of AzddMeCyd and the N4-methylated derivative of AzddMeCyd. Among the purine 2',3'-dideoxynucleosides, 3'-azido-2',3'-dideoxyguanosine (AzddGuo), 3'-fluoro-ddGuo (FddGuo), and 3'-fluoro-2,6-diaminopurine 2',3'-dideoxynucleoside (FddDAPR) were the most selective inhibitors of HIV replication.
[EN] Nucleoside compounds of formula (I): Y<1>O-G-X wherein Y<1> is a hydrogen atom or an acyl or acyloxymethyl group; G is the residue of the glycone moiety of the nucleoside; and X is a purine or pyrimidine base or an ester, amide or acyloxyalkyl derivative thereof. The compounds have antiviral activity.
