Synthesis and Antimicrobial Properties of New 4-(Alkylidene/arylidene)-amino-5-(2-furanyl)-2,4-dihydro-3H-1,2,4-triazole-3-thiones and 6-Aryl-3-(2-furanyl)-7H-1,2,4-triazolo[3,4-b][1,3,4]thiadiazines
A series of 4‐(alkylidene/arylidene)amino‐5‐(2‐furanyl)‐2,4‐dihydro‐3H‐1,2,4‐triazole‐3‐thiones (2) and 6‐aryl‐3‐(2‐furanyl)‐7H‐1,2,4‐triazolo[3,4‐b][1,3,4] thiadiazines (3) were synthesized. The configuration of 2g was assigned on the basis of 1H‐NMR data. Of the new derivatives tested, only 2b, 2g, and 4f were found to be active against Staphylococcus aureus and/or Staphylococcus epidermidis (MIC
