A vinyl azide cyclization method was used to synthesize three different carbocyclic[g]indole scaffolds as inhibitors of human nonpancreatic secretory phospholipase A2. Each scaffold demonstrated potent enzyme activity in a chromogenic assay system, with select examples also demonstrating potent activity in a secondary DOC/PC assay. Compound 11, representative of the cyclopent[g]indole series, gave an IC50 of 10 nM for the inhibition of hnps-PLA2 in the chromogenic assay.
