MK-2206 dihydrochloride

产品活性：MK-2206 dihydrochloride (MK-2206 (2HCl)) 是一种具有口服活性的，可透过血脑屏障的，变构 Akt 抑制剂，对 Akt1、Akt2 和 Akt3 的 IC₅₀ 分别为 8、12 和 65 nM。许多乳腺癌细胞系、PIK3CA 突变体和 PTEN 丢失细胞系对 MK-2206 dihydrochloride 敏感。MK-2206 dihydrochloride 诱导自噬，具有抗癌活性。

研究领域：Stem Cell/Wnt | PI3K/Akt/mTOR | Autophagy | Apoptosis

作用靶点：Organoid | Akt | Autophagy | Apoptosis

In Vitro: MK-2206 dihydrochloride (MK-2206 (2HCl)) (0-10 μM; 72 and 96 hours) inhibits the nasopharyngeal carcinoma (NPC) cell lines CNE-1, CNE-2, HONE-1, and SUNE-1 proliferation in dose- and time-dependent manner.
MK-2206 dihydrochloride (0-10 μM; 24 and 48 hours) results in a dose-dependent increase in the percentage of cells in G0/G1 phase and a concomitant reduction of cell numbers in S phase in CNE-2 and HONE-1 cells.
MK-2206 dihydrochloride (0-10 μM; 24 hours) attenuates phosphorylation levels of PRAS40 and S6 in a dose-dependent manner. MK-2206 does not effect phosphorylation of GSKα/β and AKT.
MK-2206 dihydrochloride (0-10 μM; 24 hours) increases the appearance of LC3-II in CNE-2 cells dose-dependently. Microtubule-associated protein 1 LC3 is an essential autophagy protein.

In Vivo: Both MK-2206 dihydrochloride (MK-2206 (2HCl)) doses (oral gavage; 480 mg/kg once a week and 240 mg/kg three times a week; for 2 weeks) can inhibit the growth of human CNE-2 xenografts in nude mice. No other obvious toxicity is observed in mice.
MK-2206 dihydrochloride (orally; 120 mg/kg; alternate days; for 3 weeks) significantly inhibits tumor growth in 3-5 week old athymic nude mice with GEO colon carcinoma cells.
