Biological Description

Chemical Properties

Storage & Solubility Information

Description	MM3122 is a selective type II transmembrane serine protease (TMPRSS2) inhibitor, IC50 = 0.34 nM. MM3122 effectively blocks TMPRSS2, thereby inhibiting the entry of SARS-CoV-2 and MERS-CoV into human cells.
In vitro	MM3122 (0-1 μM) has inhibitory activity against HGFA, matriptase, hepsin and thrombin with the IC50 values of 32, 0.31, 0.19 and more than 20 nM, respectively. MM3122 (0.1-100 μM) inhibits SARS-CoV-2 calu-3, MERS VSV pseudotype calu-3 and VSV-SARS CoV-2 chimera calu-3 with the EC50 values of 74, 0.87 nM and 0.43 respectively [1].
In vivo	MM3122 (i.p., 0-100 mg/kg, daily, 7 days) has no adverse effects, no weight loss or changes in harvested organs (liver, spleen and kidney) compared to controls. MM3122 (i.p., 16.7 mg/kg, once) has a half-life of 8.6 hours in plasma and 7.5 hours in lung of NSG mice[1].

Concentration of a solution resulting from a known mass of compound in a specific volume

See Example

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?
Enter 197.13 into the Molecular Weight (MW) box
Enter 10 into the Concentration box and select the correct unit (millimolar)
Enter 10 into the Volume box and select the correct unit (milliliter)
Press calculate
The answer of 19.713 mg appears in the Mass box

The dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.

See Example

An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
Enter 20 into the Volume (final) box and select the correct unit (milliliter)
Press calculate
The answer of 100 microliter (0.1 ml) appears in the Volume (start) box
