产品描述 Description

H-151 is a low MW antagonist of STING, which blocks the activation-induced palmitoylation of STING, and exhibits significant inhibitory effects on STING signalling H-151 can be used in the study of autoinflammatory diseases[1-2].

H-151(1 µM; 6 h) exerts anti-psoriasis effect through inhibiting STING/NF-κB signalling[3]. H-151(2.5 µM; 24h) improved the inflammation of peripheral blood mononuclear cells and Coatomer complex I (COPI)-deficient cell lines in patients with COPA syndrome[4].

H-151(250 /500 mg/kg; on the shaved back and right ear;5days) displayed anti-inflammatory activity in both keratinocytes and immune cells, and decreased the severity of psoriatic response in vivo[3]. H-151 downregulated the expression of granzymes and the pro-inflammatory cytokines IL-1β, IL-6, IL-15, IL-23A, and IFN-γ, and induced a pro-resolution macrophage phenotypes in ALS patients [5]. Administration of H-151 alleviated pulmonary edema, hemorrhage, thickening of the alveolar septum and infiltration of inflammatory cells; DNA damage in pulmonary tissue; and disruption of intercellular junctions in LPS-induced ALI [6]. H-151(750 nmol; i.p) treatment preserves myocardial function 28 days after myocardial infarction (MI)[7].

H-151是STING的低分子量拮抗剂,可阻断激活诱导的STING棕榈酰化,对STING信号传导有显著抑制作用,可用于自身炎症性疾病的研究[1-2]。

H-151(1µM;6 h)通过抑制STING/NF-κB信号通路发挥抗银屑病作用[3]。H-151(2.5µM;24h)改善了COPA综合征患者外周血单核细胞和Coatomer complex I (COPI)缺陷细胞系的炎症反应[4]。

H-151(250 /500 mg/kg; on the shaved back and right ear;5days)在角质形成细胞和免疫细胞中均表现出抗炎活性,并在体内降低银屑病反应的严重程度[3]。H-151下调颗粒酶和促炎细胞因子IL-1β、IL-6、IL-15、IL-23A和IFN-γ的表达,诱导ALS患者巨噬细胞出现促溶解表型[5]。H-151可减轻肺水肿、出血、肺泡隔增厚及炎症细胞浸润;肺组织DNA损伤;以及LPS诱导ALI中细胞间连接的破坏[6]。H-151(750 nmol; i.p)治疗可在心肌梗死后28天保持心肌功能[7]。

实验参考方法 Experimental Reference Method

Cell experiment [1]:

Cell lines

THP-1 cells

Preparation Method

Cells were pretreated with H-151 (1 µM) for 6 h, followed by stimulating with 2 ,3 -cGAMP (cGAMP, 10 µg/ml) for 12 h

Reaction Conditions

1 µM; 6 h

Applications

H-151 inhibited the induction of IFN-β mRNA expression triggered by cGAMP in THP-1 cells.
Animal experiment [2]:

Animal models

Female BALB/c mice (model of psoriasis induced by imiquimod)

Preparation Method

Mice were randomly divided into four groups (n = 8): control, model, model with 250 mg/kg H-151 (2.5% H-151 cream) and model with 500 mg/kg H-151 (5% H-151 cream) groups. A topical dose of 62.5 mg of 5% imiquimod cream was applied, once daily, to the shaved back and right ear in a ratio of 4:1 for five consecutive days to induce psoriasis-like skin inflammation. Control group was only treated with control cream (a mixture of wood fat and Vaseline in the ratio of one to one) on the shaved back and right ear in a ratio of 4:1 twice daily, 0.2 g per mice per treatment. The model group was treated with the control cream and imiquimod cream on the shaved back and right ear in a ratio of 4:1. Treatment groups were treated with H-151 creams (2.5% or 5% H-151 creams containing the same components as control cream) and imiquimod cream on the shaved back and right ear in a ratio of 4:1. Before imiquimod administration, the shaved back and right ear were topically treated with control cream or H-151 creams (250 or 500 mg/kg) in a ratio of 4:1, 0.2 g per mice. After imiquimod administration, another treatment with control cream or H-151 creams (250 or 500 mg/kg) was applied in the same manner mentioned above. The interval between all the treatments was 4 h. The body weight was measured every day.

Dosage form

250 /500 mg/kg; on the shaved back and right ear;5days

Applications

H-151 ameliorates IMQ(imiquimod)-induced psoriasis-like dermatitis.
