A series of thiophene [3, 2-b] pyrrole derivatives were synthesized and evaluated their abilities to inhibit anti-inflammatory activity. In this series, substituent effects at the N-1, 2 and 5 positions of thiophene [3, 2-b] pyrrole were examined. The results obtained are compared to those previously reported anti-inflammatory drugs like Tenidap sodium, Diclofenac sodium and Piroxicam. The results indicated the critical role of the group linked in the N-1 ...
