半岛bd体育手机客户端 介绍
Resatorvid (TAK-242) 是一种选择性的 TLR4信号传导抑制剂。Resatorvid 抑制 NOTNF-αIL-6的产生,其 IC50值分别为 1.8 nM,1.9 nM,1.3 nM。Resatorvid 下调 TLR4下游信号分子 MyD88 和 TRIF 的表达。Resatorvid 抑制自噬 ( autophagy),并在各种炎症性疾病中起关键作用。
生物活性

Resatorvid (TAK-242) is a selectiveToll-like receptor 4 (TLR4)inhibitor. Resatorvid inhibitsNO, TNF-αandIL-6production withIC50sof 1.8 nM, 1.9 nM and 1.3 nM, respectively. Resatorvid downregulates expression ofTLR4downstream signaling moleculesMyD88and TRIF. Resatorvid inhibitsautophagyand plays pivotal role in various inflammatory diseases[1][2].

IC50& Target[1][2]

TLR4

IL-6

1.3 nM (IC50)

TNF-R

1.9 nM (IC50)

体外研究
(In Vitro)

Resatorvid suppresses the production of NO, TNF-α, and IL-6 from LPS-stimulated human peripheral blood mononuclear cells (PBMCs) atIC50values from 11 to 33 nM[1].
Resatorvid (1-100 nM; 4 hours) inhibits mRNA expression of IL-6 and TNF-α induced by LPS and IFN-γ in RAW264.7 cells[1].
Resatorvid (1-100 nM; 15 minutes; PBMCs cells) markedly inhibits the LPS-induced phosphorylation of extracellular signal-regulated kinase 1/2 (Erk1/2), p38, and JNK/SAPK as well as degradation of IκBβ at a concentration of 100 nM[1].

RT-PCR[1]

Cell Line: RAW264.7 cells
Concentration: 1 nM, 10 nM, 100 nM
Incubation Time: 4 hours
Result: TNF-α and IL-6 mRNA expression levels were clearly suppressed at concentrations of 10 to 100 nM.

Western Blot Analysis[1]

Cell Line: PBMCs cells
Concentration: 1 nM, 10 nM, 100 nM
Incubation Time: 15 minutes
Result: The phosphorylation of mitogen-activated protein kinases induced by LPS was also inhibited in a concentration-dependent manner.
体内研究
(In Vivo)

Resatorvid (TAK-242; 3 mg/kg; intraperitoneal injection; for 2 days; male C57BL/6 mice) pretreatment markedly and significantly reverses the LPS-induced body weight loss, TA muscle loss, and muscle strength loss. TAK-242 reverses the LPS-induced shrinkage of muscle fibres and increases the interstitial space. TAK-242 blocks systemic catabolic cytokine release and skeletal muscle proteolysis in LPS-administered mice[3].

Animal Model: Male C57BL/6 mice (8-12 weeks of age) treated with lipopolysaccharide (LPS)[3]
Dosage: 3 mg/kg
Administration: Intraperitoneal injection; for 2 days
Result: Pretreatment of mice reduced or reversed all the detrimental effects of LPS.
