|Description||Tropifexor (LJN452) is a novel and highly potent agonist of FXR with EC50 of 0.2 nM in HTRF assay. It shows no significant off-target activity against a broad panel of enzyme, ion channel, nuclear receptor, and GPCR (>10000-fold selectivity for FXR).|
LJN-452 in in vitro pharmacological studies has shown to be a potent human FXR agonist with > 30,000-fold selectivity over other nuclear receptors. LJN-452 could increases BSEP and SHP expression in primary human hepatocyte.
Tropifexor has low clearance (CL = 9 mL/min/kg) and a significantly longer terminal half-life (T1/2 = 3.7 h) in rat pharmacokinetics. Oral bioavailability of tropifexor in the rat is 20% from an aqueous microemulsion formulation. In the mouse, following IV administration, Tropifexo exhibits low clearance and small volume of distribution with a half-life of 2.6 h. In the dog, following IV injection, the clearance was low and T1/2 was 7.4 h, also with a small volume of distribution (0.46 L/kg). Preclinical data demonstrate a dose-dependent increase in fibroblast growth factor 19 (FGF-19) levels with LJN-452, in single-dose or multiple-dose studies, with its target engagement in enterocyte FXRs. Tropifexor improves liver transaminases and fibrosis in the ANIT model.

* 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 (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.
