Synthesis and evaluation of substrate-mimicking cytosolic phospholipase A 2 inhibitors––reducing the lipophilicity of the arachidonyl chain isostere
摘要:
The high lipophilicity of a series of cytosolic phospholipase A(2) inhibitors has been reduced by the modification of a decyloxyphenyl chain designed to mimic the arachidonyl group of the natural substrate. These changes have resulted in an improvement in the whole cell potency of the inhibitors. (C) 2004 Elsevier Ltd. All rights reserved.

potassium channel blockingactivity. Compounds 81 and 8m produced a significant increase in APD at nanomolar concentrations, with no effect on cardiac muscle conduction velocity, and hence merit further investigation as Class III antiarrhythmic agents. Methylation of the methanesulfonamido group abolished channel-blocking activity; 4-carboxy and 3-methanesulfonamido analogues retained activity but at a reduced
