产品介绍
Docetaxel (RP-56976) 是一种微管解聚抑制剂,IC50 为 0.2 μM。多西他赛减弱 bcl-2 和 bcl-xL 基因表达的影响。 Docetaxel 在 G2/M 停止细胞周期并导致细胞凋亡。多西他赛具有抗癌活性。

Cell lines

Nine human gastric cancer cell lines

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20 ℃ for several months.

Reaction Conditions

< 0.00012 ~ >1.2 μM

Applications

The cytotoxic effect of Docetaxel was relatively greater than that of Paclitaxel in six of the nine cells. The effect of Docetaxel and Paclitaxel on MM-7 and ST-SA-I cells was less than on the other seven cultured cells.

Animal models

Mice bearing human gastric cancer xenografts (MKN-28, MKN-45 and KKLS)

Dosage form

3.75, 7.5, 15 or 22 mg/kg; i.v.; three times within a 4-day interval

Applications

Docetaxel dose-dependently inhibited tumour growth. At the doses of 15 and 22 mg/kg, Docetaxel induced complete tumor regression in all mice.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

产品描述

Docetaxel is an antineoplastic drug by inhibiting microtubule depolymerization, and attenuating of the effects of bcl-2 and bcl-xL gene expression.

Docetaxel (DOC) and Glufosfamide (GLU) single and combined treatments affect the cells viability in a dose-dependent manner. The IC50 of GLU are 70±4 μM and 86.8±8 μM in PC-3 and LNCaP cells; respectively. While, the IC50 of Docetaxel alone is found to be 3.08±0.4 nM and 1.46±0.2 nM in PC-3 and LNCaP cells; respectively. The co-treatment of GLU with Docetaxel is found to synergize the cytotoxicity and the IC50 values are decreased to be 2.7±0.1 nM and 0.75±0.3 nM in PC-3 and LNCaP cells; respectively[1]. IC50 of NCI-H460 to Docetaxel at 24 h is 116 nM and at 72 h is 30 nM. According to data reported in DTP Data Search, the mean IC50 of NCI-60 cell panel to Docetaxel is 14-34 nM[2].

In female mice, the Docetaxel-induced intestinal apoptosis in the 14-hours after light on (HALO) group is significantly greater than that in the 2-HALO group. Bax expression is significantly elevated by Docetaxel in the 2-HALO group, but not in the 14-HALO group. On the other hand, cleaved Caspase-3 expression is significantly elevated by Docetaxel in the 14-HALO group, but not in the 2-HALO group. The expressions of Wee1 and phosphorylated CKD1 are significantly elevated after dosing of Docetaxel at 14 HALO, but not at 2 HALO. In addition, Docetaxel significantly reduces survivin expression in the 14-HALO group but not in the 2-HALO group. The survivin expression level in the Docetaxel-treated 14-HALO group is significantly smaller than that in the drug-treated 2-HALO group[3]. Piperine (PIP) is administrated via intravenous bolus at 3.5 mg/kg and via oral administration at 35 mg/kg and 3.5 mg/kg, while Docetaxel (DOX) is intravenously administrated at 7 mg/kg to Sprague-Daley rats. The co-administrations of PIP at 35 mg/kg via oral administration and Docetaxel at 7 mg/kg via intravenous bolus administration in Sprague-Dawley rats. The combination use of PIP and Docetaxel results in a synergic increase of both their in vivo exposure[4].
