GSK143

产品编号 T38626 CAS 1240390-27-5

GSK143 is a potent orally active and highly selective inhibitor of spleen tyrosine kinase (SYK) with a pIC 50 of 7.5. Furthermore, GSK143 effectively inhibits phosphorylated Erk (pErk) with a pIC 50 value of 7.1. In addition, GSK143 exhibits promising anti-inflammatory properties by reducing inflammation and impeding the recruitment of immune cells in the intestinal muscularis of mice.

产品描述	GSK143 is a potent orally active and highly selective inhibitor of spleen tyrosine kinase (SYK) with a pIC 50 of 7.5. Furthermore, GSK143 effectively inhibits phosphorylated Erk (pErk) with a pIC 50 value of 7.1. In addition, GSK143 exhibits promising anti-inflammatory properties by reducing inflammation and impeding the recruitment of immune cells in the intestinal muscularis of mice.
体外活性	GSK143 (compound 20) inhibits ZAP-70 (pIC 50 =4.7), LCK (pIC 50 =5.3), LYN (pIC 50 =5.4), JAK1/2/3 (pIC 50 =5.8/5.8/5.7), Aurora B (pIC 50 =4.8), hWB (pIC 50 =6.6), hERG (pIC 50 =4.7)[1]. GSK143 (10-10000 nM; every 24 h for 3 days) has an IC 50 of 323 nM in CLL cells. GSK 143 (1 μM; 30 mins) abrogates early signalling events including SYK phosphorylation and calcium flux[2]. GSK143 (0.1-10 μM; for 30 min) reduces cytokine expression in bone marrow derived macrophages in a concentration-dependent manner[3]. Cell Viability Assay[2]Cell Line: Chronic lymphocytic leukaemia (CLL) cells Concentration: 10, 100, 1000, 10000 nM Incubation Time: Every 24 h for 3 days Result: Had an IC 50 of 323 nM.
体内活性	GSK143 (0.1-10 mg/kg; orally; 1.5 hours) reduces inflammation and prevents recruitment of immune cells in the intestinal muscularis of 1 mg/kg[3]. GSK143 (3, 10, 30, 100 mg/kg; oral; 1 hour before ovalbumin challenge) reduces the cutaneous reverse passive Arthus reaction in a dose dependent manner by approximately 50% and 70% at 10 mg/kg and 30 mg/kg, respectively[2]. GSK143 (iv of 1 mg/kg; po of 3 mg/kg) has a T 1/2 of 4.2 hours, low clearance (16 mL/min/kg), moderate bioavailability of 30% and a V ss of 4.1 L/kg in rats[1]. Animal Model: Wild type C57NL/BL6 mice, 10-12 weeks old[3]Dosage: 0.1, 1, 3, 10 mg/kg Administration: Orally; 1.5 hours before intestinal manipulation (IM) Result: Reduced inflammation and prevented recruitment of immune cells in the intestinal muscularis. Animal Model: Male CD rats (175-200 g)[1]Dosage: 1 mg/kg of iv; 3 mg/kg of po (Pharmacokinetic Analysis) Administration: IV or PO Result: Had a T 1/2 of 4.2 hours, low clearance (16 mL/min/kg), moderate bioavailability of 30% and a V ss of 4.1 L/kg.

体内实验配液计算器

请在以下方框中输入您的动物实验信息后点击计算，可以得到母液配置方法和体内配方的制备方法：比如您的给药剂量是10 mg/kg，每只动物体重20 g，给药体积100 μL，一共给药动物10 只，您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。

母液配置方法：2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL)，如您需要配置的浓度超过该产品的溶解度，请先与我们联系。

体内配方的制备方法：取 50 μL DMSO 主液，加入 300 μL PEG300，混匀澄清，再加 50 μL Tween 80，混匀澄清，再加 600 μL ddH2O, 混匀澄清。
