BioAssay: AID 637947

Antiplatelet activity in rabbit platelet rich plasma assessed as inhibition of ADP-induced platelet aggregation treated for 5 mins before ADP challenge measured for 6 mins by microplate reader

Novel 2H-benzo[b][1,4]oxazin-3(4H)-ones have been synthesized by condensation, reduction, O-alkylation and Smiles rearrangement using 3-bromo-4-hydroxy benzaldehyde, anilines, and chloroacetyl chloride as starting materials. All the synthesized compounds have been characterized by (1)H NMR, (13)C NMR, and HRMS, and tested for the inhibitory ability on platelet aggregation. The results have shown more ..

Title: Synthesis of 2H-benzo[b][1,4]oxazin-3(4H)-one derivatives as platelet aggregation inhibitors.

Abstract: Novel 2H-benzo[b][1,4]oxazin-3(4H)-ones have been synthesized by condensation, reduction, O-alkylation and Smiles rearrangement using 3-bromo-4-hydroxy benzaldehyde, anilines, and chloroacetyl chloride as starting materials. All the synthesized compounds have been characterized by (1)H NMR, (13)C NMR, and HRMS, and tested for the inhibitory ability on platelet aggregation. The results have shown that the ADP (adenosine 5'-diphosphate)-induced platelet aggregation was inhibited by 7a-g with the IC(50) value at 10.14-18.83 mumol/L. Compound 7a exhibited the most potent inhibitory effect (IC(50)=10.14 mumol/L) among all the compounds, but less potent than the control drug ticlopidine (3.18 mumol/L) and aspirin (6.07 mumol/L). The preliminary structure-activity relationship (SAR) was initially investigated in the study.
