Antimicrobial activity of 1, 3, 4-thiadiazole derivatives: a recent review

Journal of Applied Pharmaceutical Research, 2018
A few five members’ aromatic systems having three hetero-atoms at symmetrical positions, for example, thiadiazoles have been considered broadly attributable to their intriguing pharmacological properties. These thiadiazole derivatives are the heterocyclic compound which contains the five member ring along with nitrogen and sulfur atoms.
