Catalog Number: 4149
Alternate Names: U 90152
Chemical Name: 1-[3-[(1-Methylethyl)amino]-2-pyridinyl]-4-[[5-[(methylsulfonyl)amino]-1H-indol-2-yl]carbonyl]-piperazine monomethanesulfonate
Biological Activity
Non-nucleoside reverse transcriptase inhibitor (NNRTI). Selectively inhibits HIV-1 reverse transcriptase (RNA-dependent DNA polymerase) over other cellular polymerases (IC50 values are 0.26, 440 and >550 μM for HIV-1 reverse transcriptase, DNA polymerase α and DNA polymerase δ). Prevents HIV-1 spread in vivo and blocks viral replication in peripheral blood lymphocytes. Orally active.

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?
