Paclitaxel inhibits non-endothelial type human cells at 104 - to 105 -fold higher concentrations, with IC50 of 1 nM-10 nM. The selectivity of Paclitaxel inhibition of cell proliferation is also species specific, as mouse ECs are not sensitive to Paclitaxel at ultra low concentrations. Inhibition of human ECs by Paclitaxel at ultra low concentrations does not affect the cellular microtubule structure, and the treated cells do not show G2/M cell cycle arrest and apoptosis, suggesting a novel but as yet unidentified mechanism of action. In an in vitro angiogenesis assay, Paclitaxel at ultra low concentrations blocks human ECs from forming sprouts and tubes in the three-dimensional fibrin matrix. [1] In the presence of SMF, the efficient concentration of Paclitaxel on K562 cells is decreased from 50 to 10 ng/mL. The cell cycle arrest effect of Paclitaxel with or without SMF on K562 cells is correlated with DNA damage. [2] Paclitaxel alone causes a time-dependent inhibition of CDK1 in four cell lines including A549 cells, H358, H1395 cells and H1666 cells. [3]

Cells including human neonatal dermal microvascular ECs (HMVECs), human umbilical vein ECs (HUVECs), human umbilical artery ECs (HUAVECs), normal human astrocytes (NHAs), normal human dermal fibroblasts (NHDFs), normal human epidermal keratinocytes (NHEKs), human mammary epithelial cells (HMEpCs), human prostate epithelial cells (PrEpCs) and human umbilical artery smooth muscle cells (UASMCs) are cultured. Cell proliferations are performed in 96-well plates using cells between passages 6 and 12. Cells are seeded at 3000–5000 cells/well and allowed to attach for 4 hours. Paclitaxel, diluted in culture medium, is added in quadruplicate wells and the cells ae incubated for 3 days before MTS reagents are added to quantitate the live cells in each well.

The inhibition rations of Paclitaxel alone on BC-V and BC-ER tumors are 49.78% and 51.23%, respectively. Treatment of six cycles of 20 mg/kg Paclitaxel significantly reduces the percentages of Ki-67-positive cells to 20.4% in BC-V tumors and 25.1% in BC-ER tumors, respectively. [4]

よくある質問(FAQ)

質問1:
I am interested in the product S1150 for in vivo studies, could you please give some suggestions for the formulation?

回答
S1150 in 1% DMSO+30% polyethylene glycol+1% Tween 80 at 30mg/ml is a suspension. If the you want to inject it, there is another vehicle, 5% DMSO+5% Tween 80+ddH2O. S1150 can dissolve in it at 2.5mg/ml as a clear solution. It is a common formulation we used, but is not cited from reference.

質問2:
the compound was dissolved into 1ml DMSO and diluted with 1x PBS or water (500ul + 9.5 ml PBS or water). I found the white precipitation goes out. How to figure it out?

回答
Paclitaxel has very low solubility in water based solution and that's why it precipitated out once you dilute the stock with water. The vehicle we suggest is: 1% DMSO+30% polyethylene glycol+1% Tween 80.
