interaction between HIV-1 reverse transcriptase (RT) and MKC-442 analogues, a new series of compounds was synthesized and evaluated for inhibition of HIV-1 replication. The modifications include bulky alkenyl substituents at the C-5 position of the uracil ring. Analogues with reactive centers (aldehyde and epoxide functionalities) at C-5 were also synthesized in an attempt to develop HIV drugs with improved

Nucleoside analogs containing hydroxybutyl, hydroxyethoxymethyl, allyloxymethyl, and propargyloxymethyl fragments were synthesized based on 1,2,4-triazolo[3,2-c][1,2,4]triazin-7-ones isosteric to purine bases. Some of the compounds obtained inhibit in vitro reproduction of influenza and respiratory syncytial virus infection.

)aminocarbonyl optionally substituted on the aryl, an arylcarbonyl group optionally substituted or a heteroarylaminocarbonyl group. Said compound is particularly suitable as an antiviral agent and especially as an anti-HIV-1 agent.
functional groups (alkoxy/hydroxy and cyano/ester) are presented. Two groups of the title compounds were synthesised via aminolysis of 5-bromouracil and, subsequently, either coupling with an alkylating agent (2-chloromethoxyethyl acetate), or Michael-type addition to acrylonitrile/methyl acrylate. The reverse sequences for both syntheses were also studied. The target molecules were designed as non-nucleoside
