2.000mg/ml (8.26mM) Taking the 1 mL working solution as an example, add 50 μL of 40 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 Beta-Lapachone (β-Lapachone、ARQ-501) は、DNAトポイソメラーゼIIまたはリガーゼに対して阻害活性を示さない、選択的なDNAトポイソメラーゼI阻害剤です。フェーズ2。
in vitro Beta-Lapachone inhibits DNA relaxation induced by DNA topoisomerase I in a dose-dependent manner. Treatment of this compound (100 nM or greater) results in >95% inhibition of Topo I DNA unwinding activity compared to the DMSO control. This chemical (1-5 μM) causes a block in G0/G1 of the cell cycle and induces apoptosis by locking Topo I onto DNA and blocking replication fork movement in HL-60 and three human prostate cancer (DU-145, PC-3, and LNCaP) cells. It facilitates the migration of mouse 3T3 fibroblasts and human endothelial EAhy926 cells through different MAPK signaling pathways, and thus accelerates scrape-wound healing in vitro. In addition, this compound inhibits purified recombinant IDO1 activity through uncompetitive inhibition with IC50 of 0.44 μM, and it also exhibits superior retention of intracellular IDO1 inhibitory activity with an IC50 of 1.0 μM, partially dependent on biotransformation by NQO1. This chemical induces programmed necrosis of NQO1+ cancer cells by NQO1-dependent reactive oxygen species (ROS) formation and PARP1 hyperactivation. [5]
in vivo Beta-lapachone treatment (50 mg/kg) leads to potent inhibition of in vivo tumor growth in a xenograft mouse model of human ovarian cancer, and the combination of this compound and taxol produces a synergistic induction of apoptosis. In normal and diabetic (db/db) mice, treatment of this chemical results in a faster healing process than vehicle only.

反応時間 12 hours
実験の流れ IC50 calculations for each cell line are determined by DNA amount (IS) and anchorage-dependent colony formation (CF) assays. For the CF assay, cells are seeded at 500 viable cells/well in 6-well plates and incubated overnight, then treated with equal volumes of media containing beta-lapachone at final concentrations ranging from 0.005 to 50 μM in half-log increments (controls were treated with 0.25% DMSO, equivalent to the highest dose of this compound used) for 4 hour or for continuous 12-hour exposures. Plates (3 wells/condition) are stained with crystal violet, and colonies of >50 normal-appearing cells are enumerated. IC50 values for various cells are calculated using drug doses with numbers of colonies surrounding 50% of control. For DNA assays, plates are harvested for IC50 determinations 8 days after treatment using a CytoFluor 2350 fluorescence measurement system. Six-well samplings are included in the calculation of DNA fluor units for each dose. A graph of this chemical dose versus percentage control DNA in fluor units is used to calculate each IC50. All experiments are repeated at least twice, each in duplicate.
動物実験 動物モデル Human ovarian cancer cells (36M2) are established in nude mice.
