Biological Activity

[Description]:

YM-1 is a stable and soluble MKT-077 (HY-15096) analog and an orally active Hsp70 inhibitor. YM-1 induces cell death of HeLa cells and up-regulates the level of p53 and p21 proteins[1][2].

[In Vitro]

YM-1 促进 Nnos 成熟过程中依赖 Hsp70 的步骤，阻断部分与 ATP 的结合[1]。 YM-1 (0-200 μM) 激活 Hsp70 与未折叠底物的结合[1]。 YM-1 (0.001-1000 μM) 将 Hsp70 转化为紧密亲和构象，与 Hsp70 结合的 IC50 值为 8.2 μM[1]。 YM-1 (0，0.1，0.5 和 1 μM；24 小时) 促进 nNOS 泛素化[1]。 YM-1 (5 和 10 μM；24 和 48 小时) 诱导 HeLa 细胞死亡和 hTERT-RPE1 细胞生长停滞[2] YM-1 (10 μM；48 小时) 上调 p53 和 p21，下调 FoxM1 和 survivin 的蛋白水平[2]。 Western Blot Analysis[2] Cell Line: HeLa and hTERT-RPE1 cell lines Concentration: 10 μM Incubation Time: 48 hoursI Result: Increased the level of p53 and p21 and decreased the level of FoxM1 and survivin.

[In Vivo]

YM-1 (1 mM；口服，持续 7 天) 通过激活 Hsp70 挽救果蝇中的 polyQ 毒性[1]。 Animal Model: UAS-hAR52Q flies with polyQ AR-induced dihydrotestosterone (DHT) phenotype[1] Dosage: 1 mM Administration: Oral administration; 1 mM, for 7 days Result: Weakened the DHT-dependent eye degeneration phenotype and rescued DHT-dependent pupal toxicity of the polyQ AR.
