Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
2.1mg/ml Taking the 1 mL working solution as an example, add 50 μL of 42 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

5% DMSO 95% Corn oil
1.05mg/ml Taking the 1 mL working solution as an example, add 50 μL of 21 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* 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.

生物活性

製品説明 Harmine (Telepathine), a fluorescent harmala alkaloid belonging to the beta-carboline family of compounds, is a highly cell-permeant and competitive inhibitor of ATP binding to the kinase pocket of DYRK1A, with about 60-fold higher IC50 value for DYRK2. Harmine also inhibits monoamine oxidases (MAOs), PPARγ and cdc-like kinases (CLKs). Harmine inhibits 5-HT2A serotonin receptor with Ki of 397 nM.
in vitro 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[1]. 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[2].
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[1]. Harmaline exhibits a dose-dependent bioavailability[2].

実験の流れ Cell proliferation, cell death and DNA damage experiments are performed in a High Content Screening (HCS) format. The hNPCs (1,500 cells/per well) are plated on a multiwell 384 µClear plate coated with 100 µg/mL Poly-L-ornithine and 10 µg/mL laminin. After 24 h, cells are treated for 4 days in quintuplicate (five wells per condition) with harmine, INDY and pargyline in N2B27 medium supplemented with bFGF and EGF. On day 4 cells are labelled with 10 µM EdU for 2 h (cell proliferation) or BOBO™-3 (cell death) for 30 min prior to fixation or image acquisition, respectively.
