Some pyrimidines, pyrazolo[3,4-d]pyrimidines and imidazo[4,5-d]pyrimidines bearing the 5-nitro- and 5-aminothienyl-2-sulfide functionalities on the pyrimidine nucleus were synthesized and evaluated for their antifungal activity against several strains of yeasts and dermatophytes. 4-Amino-2-pyrimidinyl-5'-nitro-2'-thienylsulfide (Va) resulted active against both yeasts and dermatophytes (about 30 fold less potent than Miconazole). Compds. (II b), (V b) and (VIII b) showed only a slight activity against dermatophytes, while the other compounds were inactive.

Abstract
Some pyrimidines, pyrazolo[3,4-d]pyrimidines and imidazo[4,5-d]pyrimidines bearing the 5-nitro- and 5-aminothienyl-2-sulfide functionalities on the pyrimidine nucleus were synthesized and evaluated for their antifungal activity against several strains of yeasts and dermatophytes. 4-Amino-2-pyrimidinyl-5'-nitro-2'-thienylsulfide (Va) resulted active against both yeasts and dermatophytes (about 30 fold less potent than Miconazole). Compds. (II b), (V b) and (VIII b) showed only a slight activity against dermatophytes, while the other compounds were inactive.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
