LT052 是一种高活性和选择性BET BD1抑制剂,其IC50为 87.7 nM。LT052 表现出纳摩尔级别的 BRD4 BD1 的抑制活性,选择性是 BRD4 BD2 的 138 倍 (IC50=12.130 μM)。LT052 具有抗炎活性,可用于治疗急性痛风性关节炎。
产品描述 | LT052, a highly active and selective BET BD1 inhibitor with an IC50 of 87.7 nM, demonstrates nanomolar BRD4 BD1 potency and significant selectivity, being 138-fold more selective for BRD4 BD1 over BRD4 BD2 (IC50 =12.130 μM). Its anti-inflammatory properties make it a potential candidate for acute gout arthritis research [1]. |
靶点活性 | BRD3 BD1:246.3 nM, BRPF1B:567.5 nM, BRDT BD1:357.1 nM, BRD4 BD1:87.7 nM |
体外活性 | LT052 (1 μM) inhibits NF-κB transcriptional activity in HUVECs cells and inhibit nitric oxide (NO) production (inhibition rate: 101.89%) in RAW264.7 cells. In the evaluation of in vitro inflammatory activity, LT052 maintains comparable or better anti-inflammatory activity than the pan-BET inhibitor (JQ1) compared to the protein weak activity [1].LT052 displays the highinhibitory activity against BRD4(1) (IC 50 : 87.7±4.9 nM), BRD3(1) (IC 50 : 246.3±20.2 nM), and BRDT(1) (IC 50 : 357.1±8.3 nM). LT052 also shows inhibitory activities against BRPF1b (IC 50 : 567.5±16.9 nM). Moreover, LT052 shows a 238-fold selectivity toward BD1 over BD2 with K d of 105 nM and >25 μM for BD1 and BD2, respectively [1].LT052 (1 μM; 1 hour) inhibits MSU-induced pyroptosis of THP-1 cells through BRD4/NF-κB/NLRP3 signaling pathways [1]. |
体内活性 | LT052 (1 mg/kg; intra-articular) suppresses synovial hyperplasia and severe neutrophil infiltration that has a good therapeutic effect on MSU-induced acute gouty arthritis [1]. LT052 suppresses pyroptosis of macrophages in rat synovial tissues through regulating BRD4/NF-κB/NLRP3 signaling pathway [1]. LT052 has a high clearance rate in the range of 93.517 μL/min/mg proteins to 146.685 μL/min/mg proteins in liver microsomes of multiple species (human, monkey, dog, rat). Overall, LT052 exhibits moderately stable levels of in vitro liver microsomal metabolism [1]. Animal Model: Male Adult Sprague-Dawley rats (250-280 g) (acute gouty arthritis animal models) [1] Dosage: 1 mg/kg Administration: Intra-articular injection Result: Restored the joint circumference to normal level. |

对于不同动物的给药剂量换算,您也可以参考 更多...
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。
