Biological Description

Chemical Properties

Storage & Solubility Information

Description	PSB-603 is a selective antagonist of Adenosine A2B receptor(Ki = 0.553 nM) with anti-inflammatory effects.
In vitro	In peripheral T cells, PSB-603 (100 nM) inhibits NECA-stimulated IL-6 release about 3-fold[2]. PSB-603 (10 μM) shows no affinity for the human and rat A1 and A2A and human A3 receptors[4].
In vivo	PSB-603 (5 mg/kg; i.p.) significantly reduces inflammation in local and systemic mice models of inflammation. In the inflamed paw, PSB-603 significantly decreases the levels of the inflammatory cytokines including IL-6, TNF-α and of ROS. PSB-603 reduces inflammation of the peritoneum by decreasing the infiltration of leukocytes[3].

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

Calculate the dilution required to prepare a stock solution
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
