General description

An orally bioavailable pyrimidinopyrimidine compound that acts as a potent, reversible and ATP-competitive inhibitor of human hepatic KHK activity (KHK-C isoform; IC₅₀ = 12 nM in a transcreener ADP assay) and efficiently blocks fructose-1-phosphate secretion (IC₅₀ ≤ 400 nM in HepG2 cells). Displays ~50-fold lower potency towards metabolic kinases, namely, ribokinase, hexokinase and adenosine kinase, and minimal binding affinities to diverse receptors and ion-channels, and excellent selectivity among a panel of 31-kinases including Akt1, AMPK, CaMKI/II, InsR, IRAK4, PKA and PKCθ (IC₅₀ >>10 µM). Shown to minimally affect the activities of human cytochrome p450 isozymes (1A2, 2C19, 2D6, 2C9 and 3A4), and exhibit high volume of distribution and high rate of clearance in rats.
