GDC-0077 (RG6114) 是一种有效的，口服的选择性 PI3Kα 抑制剂 (IC₅₀=0.038 nM)。GDC-0077 (RG6114) 通过与 PI3K 的 ATP 结合位点结合而发挥其活性，从而抑制了 PIP2 到 PIP3 的磷酸化。与野生型 PI3Kα 相比，GDC-0077 (RG6114) 对突变体的选择性更高。

GDC-0077 (RG6114) is a potent, orally available, and selective PI3Kα inhibitor (IC 50 =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.

PI3Kα 0.038 nM (IC50)

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. has not independently confirmed the accuracy of these methods. They are for reference only.

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. has not independently confirmed the accuracy of these methods. They are for reference only.
