|Description||SRPIN340 is a selective SRPK inhibitor with Ki of 0.89 μM for SRPK1, showing no significant inhibitory activity against more than 140 other kinases..|
|Features||The only specific SRPK1 and SRPK2 inhibitor. Potential use in congenital diseases and viral diseases including HIV, HCV and HBV.|
SRPIN340 inhibits SR phosphorylation by SRPK in Flp-In293 cells and promotes degradation of SRp75 in a dose-dependent manner, which subsequently inhibits HIV production. SRPIN340 dose (5 mg/mL) produces no abnormalities in chromosomal structure and chromosome number of CHO cells.  SRPIN340 suppresses in a dose-dependent fashion expression of a HCV subgenomic replicon and replication of the HCV-JFH1 clone in vitro. 
|In vivo||SRPIN340 inhibits CNV formation in a dose-dependent manner in vivo. SRPIN340 significantly decreases the protein levels of VEGF, MCP-1, ICAM-1, and consequently inhibits macrophage infiltration. |
|In vitro||DMSO||70 mg/mL (200.37 mM)|
|Ethanol||70 mg/mL (200.37 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
1% DMSO+30% polyethylene glycol+1% Tween 80
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
