A novel series of pyridopyrimidine analogues 9 was identified as potent ade
nosine kinase inhibitors based on the SAR and computational studies. Substi
tution of the C7 position of the pyridopyrimidino core with C2 ' substitute
d pyridino moiety increased the in vivo potency and enhanced oral bioavaila
bility of these adenosine kinase inhibitors. (C) 2001 Elsevier Science Ltd.
