The design, synthesis, in vitro evaluation, and conformational study of nitrosopyrimidine derivatives acting as antifungal agents are reported. Different compounds structurally related with 4,6-bis(alkyl or arylamino)-5-nitrosopyrimidines were evaluated. Some of these nitrosopyrimidines have displayed a significant antifungal activity against human pathogenic strains. In this paper, we report a new group of nitrosopyrimidines acting as antifungal agents. Among them, compounds 2a, 2b and 15, the latter obtained from a molecular modeling study, exhibited antifungal activity against Candida albicans, Candida tropicalis and Cryptococcus neoformans. We have performed a conformational and electronic analysis on these compounds by using quantum mechanics calculations in conjunction with Molecular Electrostatic Potentials (MEP) obtained from B3LYP/6-31G(d) calculations. Our experimental and theoretical results have led us to identify a topographical template which may provide a guide for the design of new nitrosopyrimidines with antifungal effects.

Several alkoxy-5-nitrosopyrimidines were synthesised and high regioselective and sequential nucleophilic aromatic substitution of methoxy groups in 2-am:ino-4,6-d.imetho;xy-5nitrosopyrimidine was observed. The approach was applied to the synthesis of valu
