1,3,4-Thiadiazole: A Promising Pharmacophore

Oriental Journal Of Chemistry, 2023
Active pharmaceutical ingredients (A.P.I.) are made up of various heteroatomic moieties. Numerous heterocycle scaffolds are regarded as crucial structures. More frequently, presence of various heteroatoms viz. nitrogen, sulphur, halogens, and oxygen atoms at different position in 5- or 6-membered rings contributed them as valued source of therapeutic ...
