NSAI ACTIVITY STUDY OF 4-PHENYL-2-THIOXO-BENZO[4,5]THIENO [2,3-D]PYRIMIDINE DERIVATIVES

A series of 4-phenyl-2-thioxo-benzo[4,5]thieno[2,3-d]pyrimidine derivatives endowed with anti-inflammatory and related pharmacological properties were submitted to a more extensive study to know their exact pharmacological profile and their possible side effects. The studied compounds possess a remarkable analgesic activity, devoid of central effects. They also show an interesting anti-inflammatory profile evidenced by their effectiveness in different experimental models of inflammation. In addition, these compounds exhibit none or very little activity on CNS, scarce toxicity and low gastrointestinal agressivity.
