产品描述 Description

GDC-0068 (RG7440, Ipatasertib) is a novel highly selective ATP-competitive pan-Akt inhibitor that inhibits all three isoforms of Akt1, Akt2, and Akt3 at an IC50 of 5,18,8 nM, respectively [1,5].

GDC-0068 decreased cell viability, induced apoptosis, and inhibited phosphorylation of proline rich Akt substrate 40 kDa and p70 S6 kinase in a dose-dependent manner in PIK3CA-mutant breast cancer brain metastatic cell lines compared with PIK3CA-wildtype cell lines[6]. The combined treatment of GDC-0068 (RG7440) plus anti-microtubule chemotherapy, including vinorelbine, paclitaxel, eribulin, is contributed to anti-proliferative, pro-apoptotic, and anti-metastatic effect on human breast cancer cells[7]. GDC-0068 (RG7440) blocked Akt signaling both in cultured human cancer cell lines and in tumor xenograft models as evidenced by dose-dependent decrease in phosphorylation of downstream targets. Inhibition of Akt activity by GDC-0068 (RG7440) resulted in blockade of cell-cycle progression and reduced viability of cancer cell lines[2].

Preclinical Pharmacology demonstrates GDC-0068 (RG7440) exposure resulting in a dose-dependently pharmacodynamic effect and robust anti-tumor activity in a broad spectrum of human cancer cells in vitro and in vivo[5]. GDC-0068 (RG7440) therapy significantly inhibited the growth of WT tumors, however, for the PUMA / tumors, GDC-0068 (RG7440) therapy caused some suppression, but not so markedly compared with that of WT tumors. Immunohistochemistry staining shows that the expression of P-Akt reduced in both WT and PUMA / tumors after GDC-0068 (RG7440) therapy. PUMA-dependent antitumor effects of GDC-0068 (RG7440) in colon cancer[4]. As an ATP-competitive Akt inhibitor, GDC-0068 (RG7440) is a strong and safe target for Akt, which has been proved in a first-in-human phase I study[3].

临床前药理学证明 GDC-0068 (RG7440) 暴露会在体外和体内的广谱人类癌细胞中产生剂量依赖性药效学效应和强大的抗肿瘤活性[5] . GDC-0068（RG7440）治疗显着抑制WT肿瘤的生长，然而，对于PUMA/肿瘤，GDC-0068（RG7440）治疗引起一些抑制，但与WT肿瘤相比没有那么显着。免疫组织化学染色显示，在 GDC-0068 (RG7440) 治疗后，P-Akt 的表达在 WT 和 PUMA/肿瘤中均降低。 GDC-0068 (RG7440) 在结肠癌中的 PUMA 依赖性抗肿瘤作用[4]。作为一种 ATP 竞争性 Akt 抑制剂，GDC-0068 (RG7440) 是 Akt 的一个强大而安全的靶点，这一点已在人体第一阶段研究中得到证实[3]。
