==Overview==
==Crystal structures of adenosine deaminase complexed with potent inhibitors==
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.

Function

ADA_BOVIN Catalyzes the hydrolytic deamination of adenosine and 2-deoxyadenosine. Plays an important role in purine metabolism and in adenosine homeostasis. Modulates signaling by extracellular adenosine, and so contributes indirectly to cellular signaling events. Acts as a positive regulator of T-cell coactivation, by binding DPP4. Its interaction with DPP4 regulates lymphocyte-epithelial cell adhesion (By similarity).

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.

Publication Abstract from PubMed

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.
