  Substrate specificity of acetoxy derivatives of coumarins and quinolones towards Calreticulin mediated transacetylation: Investigations on antiplatelet function

  摘要：

  Calreticulin transacetylase (CRTAase) is known to catalyze the transfer of acetyl group from polyphenolic acetates (PA) to certain receptor proteins (RP), thus modulating their activity. Herein, we studied for the first time the substrate specificity of CRTAase towards N-acetylamino derivatives of coumarins and quinolones. This study is endowed with antiplatelet action by virtue of causing CRTAase catalyzed activation of platelet Nitric Oxide Synthase (NOS) by way of acetylation leading to the inhibition of ADP/Arachidonic acid (AA)-dependent platelet aggregation. Among all the N-acetylamino/acetoxy coumarins and quinolones screened, 7-N-acetylamino-4-methylcoumarin (7-AAMC, 17) was found to be the superior substrate to platelet CRTAase and emerged as the most promising antiplatelet agent both in vitro and in vivo. Further it caused the inhibition of cyclooxygenase-1 (Cox-1) resulting in the down regulation of thromboxane A2 (TxA2), modulation of tissue factor and the inhibition of platelet aggregation. It was also found effective in the inhibition of LPS induced pro-thrombotic conditions. (C) 2011 Elsevier Ltd. All rights reserved.
