Product Introduction
Bioactivity


英文名: KG-548

描述: KG-548 是一种ARNT/TACC3干扰剂以及HIF-1α抑制剂。KG-548 通过 ARNT 的 PAS-B 结构域与 TACC3 竞争性结合，直接干扰ARNT/TACC3复合物的形成。ARNT 是芳基烃受体核转运蛋白，也称为 HIF-β。

体外活性: HIF is a heterodimer of two bHLH-PAS (basic Helix Loop Helix-Per-ARNT-Sim) subunits, including a HIF-α paralog (HIF-1α, -2α, -3α) and aryl hydrocarbon receptor nuclear translocator (ARNT, also known as HIF-β) [1]. KG-548 (0-250 μM; 16 h for over night) exhibits the great reduction of ARNT/CCC complex formation for both coactivators, and also disrupts ARNT2 PAS-B/TACC3 interactions [1]. KG-548 (0-2 mM; 16 h for over night) dose-dependently breaks up the (320 μM) ARNT PAS-B/TACC3 complex in vitro and in cell lysate with an IC 50 value of 25 μM [1]. KG-548 significantly inhibits lactate production of glycolysis on in FaDu hypopharyngeal carcinoma cells [2]. Western Blot Analysis [1] Cell Line: HEK293T cell lysates Concentration: 0, 5, 50, 100, 250, 500 μM and 1 mM, 2 mM Incubation Time: 16 hours Result: Weakened the ARNT/TACC3 interaction from 5 μM to 500 μM dose-dependently, and decreased the protein intense of ARNT associated with immunoprecipitated TACC3 protein by 82% (500 μM), 59% (1 mM), 43% (2 mM), respectively.

存储条件: Powder: -20°C for 3 years | In solvent: -80°C for 1 year
