Abstract:
1,3,4-Thiadiazole is a multiform heterocyclic compound whose expansion in the field of medicinal chemistry is due to its unique structure and a variety of biological activities. The fivemembered ring system which contains sulfur and nitrogen atoms and is a hallmark scaffold for the manufacture of pioneering therapeutic agents, is the basic element of this compound. The 1,3,4- thiadiazole group exhibits a wide range of pharmacological activities, including antimicrobials, anti-inflammatories, anticonvulsants, antivirals, and antioxidants. This compound is a great candidate for drug discovery as it is a simple molecule subject to synthesis and interact with many different targets found in organisms. This paper aims to review recent research findings on this nucleus, highlighting the structural modifications of various thiadiazole derivatives for diverse pharmacological activities. Furthermore, this review also examines patents from 2019 to 2024 on thiadiazole derivatives for their applications in various diseases. Through the explication of the latest advancements and the comment on new trends, this study spotlights the capability of 1,3,4- thiadiazole as a core ring for the advancement of next-generation drugs.
