产品介绍
Epothilone B是微管稳定剂,Ki为0.71 μM。 它通过与αβ-微管蛋白异二聚体亚基结合而起作用,导致αβ-微管蛋白解离的减少。
生物活性

Epothilone B is amicrotubulestabilizer with aKiof 0.71μM. It acts by binding to the αβ-tubulin heterodimer subunit which causes decreasing of αβ-tubulin dissociation.

EC0.01: 1.8 μM (Microtubule/Tubulin)[1]

体外研究
(In Vitro)

Epothilone B inhibits HCT116 cells with IC50of 0.8 nM in HCT-116 cell line cytotoxicity assay[1]. Epothilone B (Patupilone) is a microtubule (MT) targeting agent. As shown by MTT cell proliferation assay, after 72 h of treatment Epothilone B efficiently inhibits cell growth with an IC50of 6 nM, while concentrations ≤1 nM are not cytotoxic. Epothilone B significantly inhibits transwell cell migration at the non-cytotoxic concentration of 1 nM, and the effect is more evident at 10 nM[2]. Epothilone B (Patupilone) is a novel, non-taxane-related and nonneurotoxic microtubule-stabilizing agent in human medulloblastoma cell lines. Epothilone B reduces the proliferative activity in the D341 cell line, with an IC50of 0.53 nM; in the D425Med cell line, with an IC50of 0.37 nM; and in the DAOY cell line, with an IC50of 0.19 nM. In the D341Med cell line, the effect of Epothilone B on clonogenic survival is at dose range of Epothilone B similar to the level of proliferative activity and viability (IC50, 0.50-0.75 nM). However, the clonogenicity of D425Med and DAOY cells is already strongly reduced at a 10-fold lower concentration of Epothilone B (IC50, 30 pM). These results overall demonstrate that Epothilone B is highly potent against different medulloblastoma cell lines[3].

体内研究
(In Vivo)

Treatment with Epothilone B (Patupilone) or ionizing radiation alone results in a partial tumor growth suppression over 10 days, whereas combined treatment exerts a strong supra-additive tumor growth control, with complete tumor regression in the follow-up period (P<0.005, for ionizing radiation or Epothilone B alone vs combined treatment)[3].
