Studies on Fused-ring Mesoionic Thiazolothienopyrimidine Systems

Cyclodehydration of 2-carboxymethylmercaptothienopyrimidin-4(3H)-ones (IV) have been studied.IV (R3=R4=Ph and R3=Me,R4=Ph) on reaction with acetic anhydride and pyridine mixture readily yield stable fusedring mesoionic systems (VI).While IV (R3=Ph,

Synthesis of 3 substituted thieno[2,3 d]pyrimidin 4(3H) one 2 mercaptoacetic acids and their ethyl esters for pharmacological screening

3 Substituted thieno[2,3 d]pyrimidin 4(3H) one 2 mercaptoacetic acids and their ethyl esters were synthesized from 2 mercaptothieno[2,3 d]pyrimidin 4 (3H) ones, which were obtained by cyclization of thienylthioureas in acidic medium. Analgesic, anti inflammatory, and anticonvulsant activities were found in some of these compounds. Significant antimicrobial activity was exhibited by thienylthioureas.
