生物活性：秋水仙碱 (Demecolcine) 是秋水仙碱的衍生物，是一种有效的有丝分裂抑制剂^[1][2]。秋水仙碱与蛋白质、微管蛋白结合并使细胞停滞在中期以进行核型分析。秋水仙碱可诱导细胞凋亡，可用于肿瘤研究^[2]。

体外：Colcemid (Demecolcine) (0.1-0.25 μg/ml, 1小时) 降低小鼠、大鼠和青蛙精母细胞的分裂 II 期补体的低倍性频率[3]。 MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内：Colcemid (Demecolcine) (0.3 mg/kg，腹腔注射) 在经 Demecolcine 腹腔注射处理后的小鼠中提高了分裂 II 期低倍性的发生率[3]。 MCE has not independently confirmed the accuracy of these methods. They are for reference only. Animal Model: Mice[3] Dosage: 0.3 mg/kg Administration: Intraperitoneal injection (i.p.) Result: Elevated 7.8-8-fold of the hypoploid and hyperploid frequencies in metaphase II cells relative to controls.
