; and the remaining variables are defined herein. Such compounds are modulators of C5a receptors, and preferably bind to C5a receptors with high affinity and exhibit neutral antagonist or inverse agonist activity at C5a receptors. Also provided herein are pharmaceutical compositions comprising such compounds, as well as methods for using such compounds in treating a variety of inflammatory and immune system disorders.

The preparation of a number of dienylimidazole via chemoselective metal-halogen exchange and their utility in ring-closing metathesis is described. Essentially all regioisomeric permutations participate in metathesis with the notable exception of 4-vinyl-5-allylimidazoles, provided that the imidazole N3 atom is protonated.

surprising then that modified purines possess the potential to impact several areas, including a better understanding of the biological effects of DNA damaging agents, enzyme/substrate interactions, and in the development of more potent medicinal agents. One focus for our research at Georgia Tech has centered around the design and synthesis of a series of extended purine analogues containing a heterocyclic
