SYNTHESIS AND ANTIVIRAL EVALUATION OF C-4-HYDRAZIDE DERIVATIVES OF 2′,3′-DIDEOXYCYTIDINE |
| |
| Abstract: | Syntheses of three hitherto unknown derivatives of 2′,3′-dideoxycytidine, namely C-4-(salicylic hydrazide)-ddC, C-4-(N-butyloxycarbonyl-isoleucine hydrazide)-ddC and its N-unprotected chlorhydrate salt have been carried out. These compounds do not induce inhibition of HIV-1 replication in cell culture experiments. Nevertheless, the modifications on the base moiety increased in all cases the lipophilicity of the parent molecule with an acceptable water solubility compared to ddC. |
