A series of novel 3,6-disubstituted 1,2,4-triazolo[3,4-b][1,3,4]thiadiazole derivatives was prepared and tested to evaluate their antimycotic, antibacterial and anti-HIV-1 activities. The reaction of thiocarbohydrazide with carboxylic acids at the melting temperature allows an improved preparation of the 5-substituted 4-amino-3-mercapto-1,2,4-triazole heterocycles which in turn allows an easier preparation of the 1,2,4-triazolo[3,4-b] [1,3,4]thiadiazole ring system. All tested compounds didn't show any significant activity.
