A series of xanthine mimetics containing 5,5 and 5,6 heterocycle fused imidazoles were synthesized as dipeptidyl peptidase IV inhibitors. Compound 7 is potent (h-DPPIV K(i)=2nM) and exhibits excellent selectivity and no species specificity against rat and human enzymes. The X-ray structure confirms that the binding mode of 7 to rat DPPIV is similar to the parent xanthines.
