|Description||XMU-MP-1 is an inhibitor of MST1/2 with IC50 values of 71.1±12.9 nM and 38.1±6.9 nM against MST1 and MST2, respectively.|
XMU-MP-1 blocks MST1/2 kinase activities, thereby activating the downstream effector Yes-associated protein and promoting cell growth. XMU-MP-1 inhibits phosphorylation of MOB1 in a dose-dependent manner. Furthermore, with increasing ATP concentration, XMU-MP-1 exhibits a proportional increase in IC50 against MST1/2, as well as an attenuated inhibition of the MST2-mediated phosphorylation of MOB1. At concentrations ranging from 0.1 to 10 μM, XMU-MP-1 reduces the phosphorylation of endogenous MOB1, LATS1/2, and YAP in human liver carcinoma (HepG2) cells in a dose-dependent manner. Similarly, XMU-MP-1 treatment inhibits hydrogen peroxide (H2O2)-stimulated MOB1 phosphorylation and MST1/2 autophosphorylation in a variety of cell lines, including mouse macrophage-like cells (RAW264.7), human osteosarcoma (U2OS), human colorectal adenocarcinoma (SW480), immortalized human retinal pigment epithelial cells (RPE1), human pleomorphic hepatocellular carcinoma (SNU-423), and HepG2, as well as primary mouse hepatocytes, without affecting the phosphorylation of JNK (c-Jun N-terminal kinase), which is a positive control for H2O2 stimulation. XMU-MP-1 treatment increases YAP nuclear translocation.
|In vivo||XMU-MP-1 displays excellent in vivo pharmacokinetics and is able to augment mouse intestinal repair, as well as liver repair and regeneration, in both acute and chronic liver injury mouse models at a dose of 1 to 3 mg/kg via intraperitoneal injection. XMU-MP-1 exhibits favorable pharmacokinetics in rats with a half-life of 1.2 hours and a bioavailability of 39.5%. The maximal phosphorylation inhibition of MOB1 and YAP is achieved between 1.5 and 6 hours after intraperitoneal dosing with XMU-MP-1 (1 mg/kg). XMU-MP-1 protects mice from DSS-induced colitis and ameliorates chronic liver injury.|

* 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.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × 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 MSDS / 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 MSDS / 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.

Frequently Asked Questions
Does XMU-MP-1 form a clear solution in - 2% DMSO+30% PEG 300+2% Tween 80+ddH2O, at a concentration of 5 mg/ml? Is this the maximum solubility or is it possible to dissolve more drug to obtain a higher concentration?
XMU-MP-1 in 2% DMSO+30% PEG 300+2% Tween 80+ddH2O at 5mg/ml is a clear solution. It is the maximum concentration. If you want a higher concentration, the content of DMSO and PEG will also be increased
