Highly Specific and Broadly Potent Inhibitors of Mammalian Secreted Phospholipases A2
摘要:
We report a series of inhibitors of secreted phospholipases A(2) (sPLA(2)S) based on substituted indoles, 6,7-benzoindoles, and indolizines derived from LY315920, a well-known indole-based sPLA(2) inhibitor. Using the human group X sPLA2 crystal structure, we prepared a highly potent and selective indole-based inhibitor of this enzyme. Also, we report human and mouse group IIA and HE specific inhibitors and a substituted 6,7-benzoindole that inhibits nearly all human and mouse sPLAs in the low nanomolar range.
