Brief Description

GDC-0980 (RG7422) is a potent, class I PI3K inhibitor for PI3Kα/β/δ/γ with IC50 of 5 nM/27 nM/7 nM/14 nM, respectively; also a mTOR inhibitor with Ki of 17 nM, and highly selective versus others PIKK family kinases.
IC50 value: 5 nM/27 nM/7 nM/14 nM(PI3Kα/β/δ/γ); 17 nM (Ki, mTOR)
Target: PI3Kα/β/δ/γ； mTOR
in vitro: GDC-0980 shows the potent and selective inhibitory activities against class I PI3K and mTOR kinase versus a large panel of kinases with Ki of 17 nM for mTOR and IC50 of 5 nM, 27 nM, 7 nM, and 14 nM for PI3Kα, β, δ, and γ, respectively. GDC-0980 reduces cancer cell viability by inhibiting cell-cycle procession and inducing apoptosis with most potency in prostate (IC50 < 200 nM 50%), <500 nM 100%), breast (IC50 <200 nM 37%, <500 nM 78%) and NSCLC lines (IC50 <200 nM 29%, <500 nM 88%) and less potency in pancreatic (IC50 <200 nM 13%, <500 nM 67%) and melanoma cell lines (IC50 <200 nM 0%, <500 nM 33%).
in vivo: In both PC-3 and MCF-7 neo/HER2 xenograft models, GDC-0980 at a dose of 1 mg/kg, exhibits significant antitumor activity by causing tumor growth delay. Furthermore, GDC-0980 results in tumor stasis or regressions at the maximum tolerated dose of 7.5 mg/kg.
