Catalog Number: 3502
Alternate Names: Patupilone
Chemical Name: (1S,3S,7S,10R,11S,12S,16R)-7,11-Dihydroxy-8,8,10,12,16-pentamethyl-3-[(1E)-1-methyl-2-(2-methyl-4-thiazolyl)ethenyl]-4,17-dioxabicyclo[14.1.0]heptadecane-5,9-dione
Biological Activity
Microtubule stabilization agent that promotes tubulin polymerization and induces G2-M cell cycle arrest (EC50 = 32 nM in HeLa cells). Inhibits proliferation of human carcinoma cell lines in vitro, including MDR cells overexpressing the P-glycoprotein efflux pump. Exhibits potent cytotoxicity in MCF-7 and A549 cells (EC50 values are 0.3 and 2.7 nM respectively). Inhibits growth of HCT-15 tumors in mice in vivo.

Molarity Calculator
Calculate the mass, volume or concentration required for a solution

The molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)
An example of a molarity calculation using the molarity calculator:
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
