'''HUMAN S-PLA2 IN COMPLEX WITH INDOLE 6'''<br />


==Overview==
==Overview==
A lead compound obtained from a high volume human non-pancreatic secretory, phospholipase A2 (hnps-PLA2) screen has been developed into a potent, inhibitor using detailed structural knowledge of inhibitor binding to the, enzyme active site. Four crystal structures of hnps-PLA2 complexed with a, series of increasingly potent indole inhibitors were determined and used, as the structural basis for both understanding this binding and providing, valuable insights for further development. The application of, structure-based drug design has made possible improvements in the binding, of this screening lead to the enzyme by nearly three orders of magnitude., Furthermore, the optimized structure (LY311727) displayed 1,500-fold, selectivity when assayed against porcine pancreatic s-PLA2.
