产品描述 Description

SLx-2119 potent inhibits activity of Rho kinase (ROCK) 2, with an IC50 value of 105nM [1]. SLx-2119 binds to ROCK2 and suppresses aberrant pro-fibrotic signalling via downregulation of pro-fibrotic gene transcription, stress fiber formation, myofibroblast activation and collagen deposition[2]. SLx-2119 has been widely used in animal models to inhibit inflammatory responses[3].

In vitro, SLx-2119 treatment for 24 hours significantly inhibited the growth of human prostate epithelial cells (PrECs) and prostate cancer PC-3 cells, with IC50 values of 2028nM and 422nM, respectively[4]. Treatment with 3μM SLx-2119 for 24 days significantly inhibited the adipocyte differentiation of human adipose-derived stem cells (hADSCs) and downregulated the protein and mRNA expressions of various adipogenesis-related and adipogenesis markers, including PPARγ, C/EBPα, SREBP-1c, Glut4 and FABP4[5]. Treatment of CD4+ T cells with 10μM SLx-2119 for 1 hour significantly reduced the intracellular levels of IL-17 and IL-21, and inhibited the phosphorylation of STAT3[6].

In vivo, SLx-2119 treatment via oral administration at a dose of 100mg/kg/day for 1 weeks significantly inhibited the liver fibrosis induced by thiocarbamide (TAA) in C57BL/6 mice [7]. Continuous intraperitoneal injection of SLx-2119 (50mg/kg/day) for 28 consecutive days can reduce the body weight of obese mice induced by high-fat diet, improve lipid metabolism, and decrease the mass of white adipose tissue[8].

SLx-2119是一种高效的Rho kinase (ROCK) 2抑制剂，IC50值为105nM[1]。SLx-2119通过结合ROCK2，下调促纤维化基因转录、抑制应力纤维形成、肌成纤维细胞活化及胶原沉积，从而抑制异常的促纤维化信号传导[2]。SLx-2119已广泛应用于动物模型中以抑制炎症反应[3]。

在体外，SLx-2119处理24小时能显著抑制人前列腺上皮细胞(PrECs)和前列腺癌PC-3细胞的生长，IC50值分别为2028nM和422nM[4]。使用3μM的SLx-2119处理人脂肪来源干细胞(hADSCs) 24天，可显著抑制hADSCs向脂肪细胞分化，并下调多种脂肪生成相关标志物的蛋白和mRNA表达水平，包括PPARγ、C/EBPα、SREBP-1c、Glut4和FABP4 [5]。用10μM的SLx-2119处理CD4+T细胞1小时，能显著降低细胞内IL-17和IL-21水平，并抑制STAT3的磷酸化[6]。

在体内，通过每日口服100mg/kg剂量的SLx-2119，连续1周，可显著抑制硫代乙酰胺诱导的C57BL/6小鼠肝纤维化[7]。连续28天每日腹腔注射SLx-2119（50mg/kg/day），能够减轻高脂饮食诱导的肥胖小鼠体重、改善脂质代谢，并减少白色脂肪组织质量[8]。

实验参考方法 Experimental Reference Method

Cell experiment [1]:

Cell lines

Human adipose-derived stem cells (hADSCs)

Preparation Method

The hADSCs were cultured in MesenPro RS medium, which was supplemented with 100units/ml penicillin and 100μg/ml streptomycin. The medium was placed in a humidified incubator at 37°C and 5% CO2. To differentiate into adipocytes, the cells were cultured for 2 days after confluence, and then the medium was replaced with StemPro adipocyte differentiation medium. During the specific culture period, the medium was changed every 3 days. During the entire experiment, the cells were treated with different concentrations (0.3, 0.5, 1, and 3μM) of SLx-2119, and stained with Oil Red O method on the 15th day.

Reaction Conditions

0.3, 0.5, 1, and 3μM; 15 days

Applications

SLx-2119 significantly dose-dependently inhibited the lipid accumulation in hADSCs.
Animal experiment [2]:

Animal models

Male Sprague-Dawley rats

Preparation Method

Male Sprague-Dawley rats (4 weeks old, 100-120g) were given a single subcutaneous injection of the vector (DMSO) or monocrotaline (MCT) (60mg/kg) on day 1. From day 8 to day 21, the rats were intraperitoneally injected with the vector (normal saline) or SLx-2119 (1mg/kg/day). On day 21, the rats were intraperitoneally injected with ketamine (100mg/kg) and sevoflurane (26mg/kg) for anesthesia, and the right ventricular pressure was measured.

Dosage form

1mg/kg/day for 14 days; i.p.

Applications

SLx-2119 treatment attenuated right ventricular systolic pressure (RVSP) in rats with pulmonary hypertension (PH) caused by MCT.
