Harmine is an alkaloid of the β-carboline family that regulates PPARγ expression through inhibition of the Wnt signaling pathway. It also selectively binds to MAO-A and reversibly inhibits monoamine oxidase A (MAO-A) but not the variant MAO-B.

|Description||Harmine is an alkaloid of the β-carboline family that regulates PPARγ expression through inhibition of the Wnt signaling pathway. It also selectively binds to MAO-A and reversibly inhibits monoamine oxidase A (MAO-A) but not the variant MAO-B.|
Harmine does not cause significant weight gain or hepatic lipid accumulation. Harmine induces expression of both PPARγ1 and PPARγ2 in primary mouse bone-marrow-derived macrophages. It might promote the anti-inflammatory action of PPARγ in this cell type. Harmine has previously been reported to interact with several cell-surface receptors, including monoamine oxidase A (MAO-A), serotonin receptor 2A (5-HT2A), imidazoline receptors (I1 and I2 sites), and cyclin-dependent kinases. Harmine has also been reported as a potent inhibitor of the dual specificity tyrosine-phosphorylation-regulated kinase (DYRK1A), which regulates cell proliferation and brain development. In fact, harmine also inhibits DYRK1B and DYRK2, but the efficiency of this inhibition is, respectively, 5- and 50-fold lower in comparison to DYRK1A. Harmine can increase proliferation of human neural progenitors.
|In vivo||Administration of harmine to diabetic mice mimics the effects of PPARγ ligands on adipocyte gene expression and insulin sensitivity. Harmine does not cause significant weight gain or hepatic lipid accumulation. It regulates metabolic and inflammatory gene expression in vivo. Harmaline exhibits a dose-dependent bioavailability.|

* 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.
