Chemical Name: (3Z,5E,7R,8R,9S,10S,11R,13E,15E,17S,18R)-18-[(1S,2R,3S)-3-[(2R,4R,5S,6R)-4-[[4-O-(Aminocarbonyl)-2,6-dideoxy-β-D-arabino-hexopyranosyl]oxy]tetrahydro-2-hydroxy-5-methyl-6-(1E)-1-propenyl-2H-pyran-2-yl]-2-hydroxy-1-methylbutyl]-9-ethyl-8,10-dihydroxy-
Biological Activity
Specific inhibitor of V-type (vacuolar) H+-ATPase that displays > 2000-fold selectivity over other H+-ATPases (IC50 values are 9.2, > 20000, > 20000 and > 20000 nM for yeast V-type, F-type, P-type H+-ATPases and porcine P-type Na+,K+-ATPase respectively). Blocks cell surface expression of virus envelope glycoproteins without affecting synthesis and exhibits cytotoxicity in several cell lines.

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?
