MT 63-78 is a specific and potent direct AMPK activator with an EC50 of 25 μM. MT 63-78 also induces cell mitotic arrest and apoptosis. MT 63-78 blocks prostate cancer growth by inhibiting the lipogenesis and mTORC1 pathways. MT 63-78 has antitumor effects[1].
MT 63-78 (0-50 μM; 4 days; LNCaP and PC3 cells) treatment shows a dose-dependent decrease in cell number, and concomitant to the activation of AMPK signaling[1].MT 63-78 (25 μM; 24 hours; LNCaP and CRPC cells) treatment induces a significant enrichement in the G2/M population[1].MT 63-78 (0-50 μM; 24 hours; LNCaP, PC3, C4-4, C4-2B, CL1and 22RV1cells) treatment induces reduction of anti-apoptotic Mcl-1 in concert with accumulation of the pro-apoptotic BH3-only protein Puma[1].MT 63-78 (0-50 μM; 30 minutes; LNCaP and PC3 cells) treatment shows a dose-dependent phosphorylation of the two major AMPK targets Acetyl-CoA Carboxylase (ACC) on Ser79 and of Raptor on Ser792. And also increases Thr172 phosphorylation on the AMPK α subunit[1]. Cell Viability Assay[1] Cell Line: LNCaP and PC3 cells
MT 63-78 (30 mg/kg; intraperitoneal injection; daily; for 14 days; C57 BL/6 male mice) treatment leads to a 33% inhibition of tumor growth[1]. Animal Model: C57 BL/6 male mice bearing LNCaP tumors[1]
