Batabulin sodium

CAS No. : 195533-98-3

MCE 国际站：Batabulin sodium

产品活性：Batabulin sodium (T138067 sodium) 是一种抗肿瘤剂，可与 β-微管蛋白同种型的子集共价且选择性地结合，从而破坏微管 (microtubule) 聚合。Batabulin sodium 影响细胞形态并导致细胞周期停滞，最终诱导凋亡性细胞死亡。

研究领域：Cell Cycle/DNA Damage  |  Cytoskeleton  |  Apoptosis

作用靶点：Microtubule/Tubulin  |  Apoptosis

In Vitro: Batabulin (T138067; 30-300 nM; 24 hours; MCF7 cells) treatment shows approximately 25-30% tetraploid (4n) DNA content in cells, indicating an arrest at the G2/M cell-cycle boundary.
Batabulin (T138067; 30-300 nM; 24-48 hours; MCF7 cells) treatment shows 25-30% apoptosis. After a 48-hr exposure to 100 nM Batabulin, approximately 50-80% of the cell population is undergoing apoptosis.
Batabulin (T138067) binds covalently and selectively to a subset of the β-tubulin isotypes, thereby disrupting microtubule polymerization. Covalent modification occurs at a conserved Cys-239 shared by the β1, β2, and β4 tubulin isotypes. Cells exposed to Batabulin become altered in shape, indicating a collapse of the cytoskeleton, and show an increase in chromosomal ploidy.

In Vivo: Batabulin (T138067; 40 mg/kg; intraperitoneal injection; once per week; on days 5, 12, and 19; male athymic nude mice) treatment impairs the growth of the drug-sensitive CCRF-CEM tumors.
