5,6,7-Trisubstituted 4-Aminopyrido[2,3-d]pyrimidines as Novel Inhibitors of Adenosine Kinase
摘要:
The synthesis and structure-activity relationship of a series of 5,6,7-trisubstituted 4-aminopyrido[2,3-d]pyrimidines as novel nonnucleoside adenosine kinase inhibitors is described. A variety of alkyl, aryl, and heteroaryl substituents were found to be tolerated at the C5, C6, and C7 positions of the pyridopyrimidine core. These studies have led to the identification of analogues that are potent inhibitors of adenosine kinase with in vivo analgesic activity.

The efficient cross-coupling reaction to afford ketones from pyridine carboxylic acid chlorides and alkylzinc reagents in the presence of Pd(phen)Cl 2 is reported. In the case of chloronicotinoyl chlorides, none ofNegishi cross-coupling products of 2-chloroazine moiety was formed. The catalyst loading could be reduced up to 0.01 mol%.
