≥5mg/ml Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
* <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 ルクソリチニブ (Ruxolitinib (INCB018424)) は、最初に臨床試験が行われた強力で選択的なJAK1/2 阻害剤であり、IC50 はそれぞれ 3.3 nM/ 2.8 nM、JAK1/2 に対して JAK3 の 130 倍の選択性を示します。ルクソリチニブはマイトファジー (mitophagy) によって抗腫瘍作用を示します。また、オートファジー (autophagy) を誘導し、アポトーシス (apoptosis) を促進します。
in vitro Ruxolitinib (INCB18424) potently and selectively inhibits JAK2V617F-mediated signaling and proliferation in Ba/F3 cells and HEL cells. This compound markedly increases apoptosis in a dose dependent manner in Ba/F3 cells. It (64 nM) results in a doubling of cells with depolarized mitochondria in Ba/F3 cells. This chemical inhibits proliferating of erythroid progenitors from normal donors and polycythemia vera patients with IC50 of 407 nM and 223 nM, respectively. It demonstrates remarkable potency against erythroid colony formation with IC50 of 67nM. [1]
in vivo INCB018424 (180 mg/kg, orally, twice a day) results in a survival rate of greater than 90% by day 22 in a JAK2V617F-driven mouse model. This compound (180 mg/kg, orally, twice a day) markedly reduces splenomegaly and circulating levels of inflammatory cytokines, and preferentially eliminates neoplastic cells, resulting in significantly prolonged survival without myelosuppressive or immunosuppressive effects in a JAK2V617F-driven mouse model. [1] In the double-blind trial of myelofibrosis, the primary end point is reached in 41.9% of patients in the Ruxolitinib (INCB18424) group as compared with 0.7% in the placebo group. It results in maintaining reduction in spleen volume and improvement of 50% or more in the total symptom score. [2] A total of 28% of the patients in the group receiving this compound (15 mg twice daily) has at least a 35% reduction in spleen volume at week 48 in patients with myelofibrosis, as compared with 0% in the group receiving the best available therapy. The mean palpable spleen length has decreased by 56% with it but has increased by 4% with the best available therapy at week 48. Patients in the ruxolitinib group has an improvement in overall quality-of-life measures and a reduction in symptoms associated with myelofibrosis. [3]

キナーゼアッセイ Binding assay
Recombinant proteins are expressed using Sf21 cells and baculovirus vectors and purified with affinity chromatography. JAK kinase assays use a homogeneous time-resolved fluorescence assay with the peptide substrate (-EQEDEPEGDYFEWLE). Each enzyme reaction is carried out with Ruxolitinib (INCB18424) or control, JAK enzyme, 500 nM peptide, adenosine triphosphate (ATP; 1mM), and 2% dimethyl sulfoxide (DMSO) for 1 hour. The 50% inhibitory concentration (IC50) is calculated as the concentration of this compound required for inhibition of 50% of the fluorescent signal.
細胞アッセイ 細胞株 Ba/F3 and HEL cells
濃度 3 μM
反応時間 48 hours
実験の流れ Cells are seeded at 2 × 103/well of white bottom 96-well plates and treated with Ruxolitinib (INCB018424) from DMSO stocks (0.2% final DMSO concentration), followed by incubation for 48 hours at 37 ℃ with 5% CO2. Viability is measured by cellular ATP determination using the Cell-Titer Glo luciferase reagent or viable cell counting. Values are transformed to percent inhibition relative to vehicle control, and IC50 curves are fitted according to nonlinear regression analysis of the data using PRISM GraphPad.
