In vitro
In vitro Purvalanol A decreases cell viability in dose-dependent manner in MCF-7 and MDA-MB-231 cell lines. Purvalanol A induces cell viability loss by 50 % in MCF-7 cells but MDA-MB-231 cells sre less sensitive to Purvalanol A (32 % decreases in cell viability). Purvalanol A induces mitochondria-mediated apoptosis in MCF-7 and MDA-MB-231 cells.[2] Purvalanol A effectively prevents c-Src-mediated transformation by inhibiting both cell cycle progression and c-Src signaling, and effectively suppresses the anchorage independent growth of some human cancer cells in which c-Src is up-regulated. Purvalanol A has a stronger inhibitory effect on the anchorage-independent growth of HT29 and SW480 human colon cancer cells. [3]

Concentrations 100 μM
Incubation Time 24 h
Method Cells are seeded at 10000 density in 96-well plates and treated with various concentrations of Purvalanol A (0-100 μM) for 24 h. Cells are exposed to 10 μL of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltet- razolium bromide dye (5 mg/mL) and are incubated at 37℃ for 4 h. In order to solubilize the formazan crystals 100 μL DMSO is added. Absorbance is determined at 570 nm spectrophotometrically.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
