|Description||Galunisertib (LY2157299) is a potent TGFβ receptor I (TβRI) inhibitor with IC50 of 56 nM in a cell-free assay. Phase 2/3.|
LY2157299 potently inhibits the TGFβ receptor signaling. LY2157299 abolishes the TGFβ induced Smad2 phosphorylation in HUVEC cells. LY2157299 also shows dose dependent potentiation of VEGF or bFGF induced cell proliferation in HUVEC. LY2157299 also promotes VEGF induced HUVEC cell migration. LY2157299 potentiates angiogenesis in the in vitro VEGF-stimulated cord formation assay.  LY2157299 inhibits TGF-β-mediated SMAD2 activation and hematopoietic suppression in primary hematopoietic stem cells in a dose-dependent manner. LY2157199 treatment stimulates hematopoiesis from primary MDS bone marrow specimens.  In human glioblastoma (GBM) cells, LY2157299 treatment blocks signaling through the heteromeric TGFβ receptor complex to reduce levels of active, phosphorylated SMAD. 
|In vivo||Although anti-tumor activity has been observed in several pre-clinical models, LY2157299 fails to show significant in vivo angiogenic effects in the 4T1, Colo205, or A549 xenograft models.  Administration of LY2157299 ameliorates anemia in a TGF-β overexpressing transgenic mouse model of bone marrow failure.  Oral administration of LY2157299 at 75 mg/kg/day displays significant antitumor activity against both Calu6 and MX1 xenografts in mice.  In vivo, LY2157299 induces angiogenesis and enhances VEGF and basic-fibroblast-growth-factor-induced angiogenesis in a Matrigel-plug assay, whereas adding an alpha5-integrin-neutralizing antibody to the Matrigel selectively inhibits this enhanced response. |

|In vitro||DMSO||74 mg/mL (200.31 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
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 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.
