Thiadiazine is a heterocyclic compound containing a six-membered ring composed of three carbon atoms, one sulfur atom, and two nitrogen atoms.[1] It exists in several isomeric forms, each characterized by the different arrangement of the sulfur and nitrogen atoms in the ring structure.[2] Common isomers include 1,2,4-thiadiazine, 1,2,6-thiadiazine, and 1,3,4-thiadiazine.[1] Thiadiazines have gained significant interest in organic and medicinal chemistry research due to their diverse potential biological activities, including antimicrobial, anti-inflammatory, and muscle relaxant properties. They have been explored their potential applications in treating conditions such as Huntington's disease, rheumatoid arthritis, and type 2 diabetes.[2][1]
