Sample solution is provided at 25 µL, 10mM.
GDC-0326 is a potent and selective PI3Kα inhibitor with a Ki of 0.2 nM.
GDC-0326 is highly selective over other kinases. In a panel of 235 kinases, only one is inhibited by >50% by GDC-0326 when tested at 1 uM. GDC-0326 is not an inhibitor of cytochrome P450 enzymes tested (IC50>10 uM against 3A4, 2C9 1A2, 2C19, 2D6), is highly permeable in MDCK cells and has thermodynamic solubility of 82 ug/mL at pH 7.4[1].
GDC-0326 is highly stable in human and rat liver microsomes, and there is a good correlation with in vivo rat clearance. It is found to have consistently low clearance and high oral bioavailability across species tested, enabling significant sustained free drug levels. Daily administration of GDC-0326 orally at 0.78, 1.56, 3.25, 6.25, or 12.5 mg/kg results in dose-dependent increase in TGI (73%, 79%, 83%, 101%, and 110%, respectively) and tumor regressions (6 PRs out of 10 animal at 6.25 and 12.5 mg/kg) when compared to vehicle treated mice. Daily administration of GDC-0326 orally at 0.78, 1.56, 3.25, 6.25, or 12.5 mg/kg also results in dose-dependent increase in TGI (73%, 97%, 97%, 122%, and 121%, respectively) in the KPL-4 xenograft model. Notably, maximum efficacy of GDC-0326 is observed at 6.25 mg/kg in the KPL-4 model based on TGI and tumor regressions (9 PRs and 1 CR out of 10 animal treated) when compared to vehicle treated mice. Doses of GDC-0326 up to 12.5 mg/kg are well tolerated based on less than 10% body weight loss (data not shown)[1].

Animal experiment: | Rats: Male Sprague-Dawley rats are dosed intravenously with 1 mg/kg of GDC-0326 prepared in 60% PEG400/10% Ethanol. Male Sprague-Dawley rats are dosed PO with 5 mg/kg of GDC-0326 in 0.5% methylcellulose with 0.2% Tween 80 (MCT)[1]. Mice: Female NCR nude mice are dosed intravenously with 1 mg/kg of GDC-0326 prepared in 60% PEG400/10% Ethanol and PO at 25 mg/kg in 0.5% methylcellulose with 0.2% Tween 80 (MCT)[1]. |
