Rapamycin (Sirolimus) 是一种有效且特异性的mTOR抑制剂,作用于 HEK293 细胞,抑制mTOR,IC50为 0.1 nM。Rapamycin 与 FKBP12 结合且抑制mTORC1。Rapamycin 还是一种自噬 (autophagy) 激活剂,免疫抑制剂。
生物活性 | Rapamycin (Sirolimus; AY 22989) is a potent and specificmTORinhibitor with anIC50of 0.1 nM in HEK293 cells. Rapamycin binds to FKBP12 and specifically acts as an allosteric inhibitor ofmTORC1[1]. Rapamycin is anautophagyactivator, an immunosuppressant[2]. |
IC50& Target[1][2] | mTOR 0.1 nM (IC50, in HEK293 cells ) | Microbial Metabolite | Autophagy | Human Endogenous Metabolite |

体外研究 (In Vitro) | Rapamycin (12.5-100 nM; 24 hours) treatment exerts modest inhibitory effect on lung cancer cell proliferation in a dose-dependent manner in all cell lines (A549, SPC-A-1, 95D and NCI-H446 cells) tested, achieving about 30-40% reduction in cell proliferation at 100 nM vs. ~10% reduction at 12.5 nM[3]. Lung cancer cell line 95D cells are exposed to Rapamycin (10 nM, 20 nM) and RP-56976 (1 nM, 10 nM) alone or in combination (Rapamycin 20 nM+ RP-56976 10 nM). After 24 hours exposure to Rapamycin or RP-56976 alone does not significantly alter the level of expression or phosphorylation of ERK1/2, whereas cells treated with the combination of Rapamycin with RP-56976 exhibit a marked reduction in the phosphorylation levels of ERK1/2[3].
Cell Viability Assay[3] Cell Line: | Lung cancer cell lines A549, SPC-A-1, 95D and NCI-H446 | Concentration: | 12.5 nM, 25 nM, 50 nM, 100 nM | Incubation Time: | 24 hours | Result: | Treatment exerted modest inhibitory effect on lung cancer cell proliferation in a dose-dependent manner in all cell lines. |
Western Blot Analysis[3] Cell Line: | 95D cells | Concentration: | 10 nM and 20 nM | Incubation Time: | 24 hours | Result: | Combination treatment with RP-56976 decreased phosphorylation of ERK. |

体内研究 (In Vivo) | 雷帕霉素(2.0 mg/kg;腹腔内注射;每隔一天;28天)单独使用有中等的抑制作用。然而,与对照组、雷帕霉素单药组相比,二甲双胍联合雷帕霉素对肿瘤生长的抑制作用明显增强[4]。
Animal Model: | 24 malenu/numice aged 4-5 week old (15-20 g)[4] | Dosage: | 2.0 mg/kg | Administration: | Intraperitoneal injection; every other day; 28 days | Result: | Had a moderate inhibitory effect in monotherapy group. The combination with Metformin exerted a significantly increased inhibition of tumor growth. |
