The compounds were evaluated in a vesicle assay with isolated cPLA2α and in cellular assays with intact human platelets. Systematic variation led to 3-methylhydrogen 1-[3-(4-decyloxyphenoxy)-2-oxopropyl]indole-3,5-dicarboxylate (57), which revealed the highest activity against the isolated enzyme. With an IC50 value of 4.3 nM in this assay, it is one of the most potent in vitro cPLA2α inhibitors known today. %I ACS Publications
