Synthesis and Biochemical Testing of 3-(Carboxyphenylethyl)imidazo[2,1-f][1,2,4]triazines as Inhibitors of AMP Deaminase.


ABSTRACT: C-Ribosyl imidazo[2,1-f][1,2,4]triazines and 3-[2-(3-carboxyphenyl)ethyl]-3,6,7,8-tetrahydroimidazo[4,5-d][1,3]diazepin-8-ols represent two classes of known AMP deaminase inhibitors. A combination of the aglycone from the former class with the ribose phosphate mimic from the latter led to the 3-[2-(3-carboxyphenyl)ethyl]imidazo[2,1-f][1,2,4]triazines, which represent a new class of AMP deaminase inhibitors. The best compound, 3-[2-(3-carboxy-5,6,7,8-tetrahydronaphthyl)ethyl]imidazo[2,1-f][1,2,4]triazine (8), was a good inhibitor of all three human AMPD recombinant isozymes (AMPD1, AMPD2, and AMPD3; IC50 = 0.9-5.7 ?M) but a poor inhibitor of the plant recombinant enzyme (Arabidopsis FAC1; IC50 = 200 ?M).
