| 生物活性 | GDC-0077 (RG6114) is a potent, orally available, and selective PI3Kα inhibitor (IC50=0.038 nM). GDC-0077 (RG6114) exerts its activity by binding to the ATP binding site of PI3K, thereby inhibiting the phosphorylation of PIP2 to PIP3. GDC-0077 (RG6114) is more selective for mutant versus wild-type PI3Kα. |

| 体内研究 | GDC-0077 (p.o.) results in tumor regressions, induction of apoptosis, and a reduction of pAKT, pPRAS40, and pS6RP in a dose-dependent fashion in patient-derived PIK3CA-mutant breast cancer xenograft models. |
| 体外研究 | GDC-0077 (RG6114) is >300-fold more selective for PI3Kα over the other class I PI3K isoforms (β, δ, and γ) and >2000-fold more selective over PIK family members. GDC-0077 selectively degrades mutant PI3Kα in a proteasome-dependent fashion resulting in reduction of PI3K pathway activity biomarkers such as pAKT and pPRAS40, inhibition of cell proliferation, and increased apoptosis in human PIK3CA-mutant breast cancer cell lines to a greater extent when compared to PIK3CA wild-type cells. |
