Catalog Number: 3993
Alternate Names: Seocalcitol
Chemical Name: (1R,3S,5Z)-5-[(2E)-2-[(1R,3aS,7aR)-1-[(1R,2E,4E)-6-Ethyl-6-hydroxy-1-methyl-2,4-octadien-1-yl]-octahydro-7α-methyl-4H-inden-4-ylidene]ethylidene]-4-methylene-1,3-cyclohexanediol
Biological Activity
Vitamin D receptor (VDR) agonist; analog of calcitriol (Cat. No. 2551). Exhibits anti-tumor and anti-proliferative activity with reduced hypercalcemic effects. 60 times more potent in inhibiting MCF-7 cell growth in vitro; also shown to induce autophagy in MCF-7 cells. Reverses the effects of parathyroid hormone-related protein (PTHrP).

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?
