Synthesis and anti-platelet evaluation of 2-benzoylaminobenzoate analogs

Fifty-two 2-benzoylaminobenzoate analogs were synthesized and subjected to anti-platelet aggregation assay using arachidonic acid (AA), collagen (Col), thrombin (Thr), and U46619 as inducers. The results revealed that most of 2-benzoylaminobenzoic acid derivatives showed a selectively inhibitory effect on AA-induced platelet aggregation. As a result of the 2-benzoylaminobenzoic acid derivatives (18, 44, and 46), there were no inhibitory effects on platelet aggregation induced by U46619, but these elicited an inhibitory effect on thromboxane B2 formation at 1.0 μM. These 2-benzoylaminobenzoate analogs were therefore proposed as cyclooxygenase inhibitors.
