Abstract

Thieno[3,2-d]pyrimidine ring framework comprises a significant class of heterocyclics that serve as a promising platform showing different pharmacological activities. The interest in thieno[3,2-d]pyrimidine cores for pharmaceutical products makes this scaffold an exceptionally helpful building block for organic chemistry. This review presents current research on thieno[3,2- d]pyrimidines and elucidates their biological importance in anti-cancer, anti-infectious, anticonvulsant, anti-diabetic, CNS, and osteoporosis drug discoveries. Patents on the thieno[3,2- d]pyrimidines are also elaborated as a piece of useful information. Here, we additionally focus on the synthesis of this vital ring and the discovery of new thieno[3,2-d]pyrimidines.
