CAS No. 1702259-66-2
H3B-6527 is a highly selective covalent FGFR4 inhibitor with an IC50 value of <1.2 nM and at least 250-fold selectivity over FGFR1-3 (IC50 values of 320, 1,290 and 1,060 nM respectively).

KYSE150 and KYSE450 cells were treated each day with 1 μM H3B‐6527 or left untreated for three days, and lysates were immunoblotted with indicated antibodies. Western blotting demonstrated that the expression of EMT‐related markers (E‐cadherin, N‐cadherin, Claudin‐1, Vimentin, and Snail) was altered with FGFR4 blockade.

|Description||H3B-6527 is a highly selective covalent FGFR4 inhibitor with an IC50 value of <1.2 nM and at least 250-fold selectivity over FGFR1-3 (IC50 values of 320, 1,290 and 1,060 nM respectively).|
H3B-6527 shows robust inhibition of the target kinase FGFR4 with an IC50 value of <1.2 nmol/L and at least 250-fold selectivity over FGFR1-3 (IC50 values of 320, 1,290 and 1,060 nmol/L respectively). TAOK2, JNK2, and CSF1R are also less sensitive to H3B-6527 treatment with IC50 values of 690, >10,000, and >10,000 nmol/L, respectively. H3B-6527 inhibits FGFR4 signaling, proliferation, and leads to apoptosis in a HCC cell line (Hepatocellular carcinoma). Treatment on Hep3B cells leads to robust activation of caspase-3/7, an apoptotic marker, in a concentration-dependent manner, indicating FGFR4 inhibition by H3B-6527 leads to cell death in HCC cell lines. H3B-6527 has the selectivity and the selective dependence on FGFR4 across cancer types.
|In vivo||In the Hep3B human HCC xenograft mouse model, H3B-6527 shows dose-proportional plasma exposures and greater than dose-proportional tumor exposures within the dose range evaluated (30, 100, and 300 mg/kg). The H3B-6527 pharmacodynamic response as measured by CYP7A1 mRNA and pERK1/2 protein levels is dose dependent, with higher doses leading to sustained responses. Oral treatment of H3B-6527, twice daily, inhibits xenograft growth in a dose-dependent manner in nude mice, with the 300 or 100 mg/kg twice daily, significantly inhibiting tumor growth in both Hep3B subcutaneous and orthotopic xenograft model and causing tumor regressions in the subcutaneous xenograft model. Palbociclib can enhance H3B-6527 efficacy and promote tumor regression in JHH-7 model where H3B-6527 as a single agent can only lead to tumor stasis.|

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.
