GNE 477 Usage And Synthesis

Biological Activity

gne-477 is a potent dual pi3k/mtor inhibitor. owing to the common association with oncogenic malignancies, the pi3k/akt/mtor signaling pathway is regarded as an attractive area of research for the identification of oral small molecule inhibitors.

in vitro

gne-477 was found to inhibit pi3k-α, β, δ, and γ with ic50s of 4, 86, 6, and 15 nm, respectively. [1].

in vivo

a direct comparison of gne-477 with its des-methyl analog revealed that the trend of reduced in vivo clearance in rats is also observed in dogs and mice. the clearance improvement was significant in dogs where the des-methyl analog was cleared at two-thirds the rate of hepatic blood flow while gne-477 had low clearance. in an study evaluating the tumor growth inhibition of a pc3 tumor xenograft10 over 14 days, stasis was achieved at a 20 mg/kg qd dose of gne-477 and significant inhibition was found with doses as low as 1 mg/kg qd. gne-477 was generally well tolerated during this study as shown by acceptable levels of weight loss comparable to that in the vehicle cohort [1].

IC 50

4 and 21 nmol/l for pi3k and mtor, respectively
