Crystal structure of adenosine deaminase complexed with potent inhibitors
Overview
We disclose optimization efforts based on the novel non-nucleoside, adenosine deaminase (ADA) inhibitor, 4 (K(i) = 680 nM). Structure-based, drug design utilizing the crystal structure of the 4/ADA complex led to, discovery of 5 (K(i) = 11 nM, BA = 30% in rats). Furthermore, from, metabolic considerations, we discovered two inhibitors with improved oral, bioavailability [6 (K(i) = 13 nM, BA = 44%) and 7 (K(i) = 9.8 nM, BA =, 42%)]. 6 demonstrated in vivo efficacy in models of inflammation and, lymphoma.
