Small, non-peptide C5a receptor antagonists: part 1

Bioorg Med Chem Lett. 2008 Oct 15;18(20):5601-4. doi: 10.1016/j.bmcl.2008.08.106. Epub 2008 Aug 31.

Abstract

The optimisation of a series of amides for C5a receptor binding and functional activity, and physicochemical properties is described. The initial hit, 1 (IC(50) 1 microM), was discovered during high throughput screening, from which highly potent C5a receptor antagonists (e.g.14, IC(50) 5 nM) were developed.
