Docetaxel Trihydrate (RP-56976 Trihydrate) is an antineoplastic agent and inhibitsmicrotubule depolymerizationwith anIC₅₀value of 0.2 μM^[1]. Docetaxel Trihydrate is a semisynthetic analog of taxol and attenuates the effects of bcl-2 and bcl-xL gene expression. Docetaxel Trihydrate arrests the cell cycle at G2/M and leads to cellapoptosis^[1][3].

Microtubule^[1]

Docetaxel Trihydrate (RP-56976 Trihydrate) and Glufosfamide (GLU) single and combined treatments affect the cells viability in a dose-dependent manner. The IC₅₀of GLU are 70±4 μM and 86.8±8 μM in PC-3 and LNCaP cells; respectively. While, the IC₅₀of 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 IC₅₀values are decreased to be 2.7±0.1 nM and 0.75±0.3 nM in PC-3 and LNCaP cells; respectively^[1]. IC₅₀of 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 IC₅₀of NCI-60 cell panel to Docetaxel is 14-34 nM^[2].

In female mice, the Docetaxel Trihydrate (RP-56976 Trihydrate)-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].
