Ecdysone (α-Ecdysone) 是昆虫和草药中的主要类固醇激素,可以激活盐皮质激素受体 (MR) 并诱导细胞凋亡 (apoptosis)。Ecdysone 通过其活性代谢物 20-羟基蜕皮激素 (Crustecdysone; 20E; HY-N6979) 在协调发育过渡和体内稳态睡眠调节中起重要作用。
生物活性 | Ecdysone (α-Ecdysone), a major steroid hormone in insects and herbs, triggersmineralocorticoid receptor(MR)activation and induces cellularapoptosis. Ecdysone plays essential roles in coordinating developmental transitions and homeostatic sleep regulation through its active metabolite 20-hydroxyecdysone (Crustecdysone; 20E; HY-N6979)[1][2]. |

体外研究 (In Vitro) | Ecdysone (α-Ecdysone; 100 nM; for 48 hours) causes renal tubular inner medullary collecting duct cells (IMCD) apoptosis[1]. Ecdysone (10, 100 nM; for 48 hours) induces the expression of a-smooth muscle actin (SMA), a standard mesenchymal marker in a dose dependent fashion in inner medullary collecting duct cells (IMCD). Ecdysone elevates the expression of cleaved caspase 3 in a dose dependent fashion[1]. Ecdysone (10, 100 nM; for 12, 24 hours) suppresses cell motility and scratch wound closure to a comparable extent[1]. Ecdysone treatments (100 nM; for 24, 48 hours) induces a branched spindle mesenchymal-like cell shape[1].
Apoptosis Analysis[1] Cell Line: | Inner medullary collecting duct cells (IMCD) | Concentration: | 100 nM | Incubation Time: | For 48 hours | Result: | Caused renal tubular cell apoptosis. |
Western Blot Analysis[1] Cell Line: | IMCD cells | Concentration: | 10, 100 nM | Incubation Time: | For 48 hours | Result: | Induced the expression of a-smooth muscle actin (SMA), a standard mesenchymal marker in a dose dependent fashion. |

体内研究 (In Vivo) | Ecdysone (α-Ecdysone; 6 μg/g/day; SC; for 14 days) evidently impaires kidney function marked by a statistically significant increase in BUN levels and amplifies renal expression of α-SMA in male C57BL/6 mice aged 10 weeks. Ecdysone confers an MR dependent nephropathic effect[1].
