Small, non-peptide C5a receptor antagonists: part 2

Bioorg Med Chem Lett. 2008 Oct 15;18(20):5605-8. doi: 10.1016/j.bmcl.2008.08.101. Epub 2008 Aug 31.

Abstract

Starting from 2, several highly potent C5a receptor antagonists were synthesised through alpha-amide substitution. Attempts to increase the polarity of these compounds through the introduction of basic centres or incorporation into weakly basic heterocycles is described.
