Catalog Number: 5313
Alternate Names: Varespladib
Chemical Name: 2-[[3-(2-Amino-2-oxoacetyl)-2-ethyl-1-(phenylmethyl)-1H-indol-4-yl]oxy]acetic aci
Biological Activity
Selective secreted phospholipase A2 (sPLA2) inhibitor (IC50 = 50 - 750 nM for a range of sPLA2 isoforms). Has no effect on cytosolic PLA2 or COX-1 and COX-2 activity. Attenuates sPLA2-induced thromboxane formation in bronchoalveolar lavage (BAL) cells. Also suppresses sPLA2-induced contractions of lung pleural strips ex vivo. Orally available.

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?
