The article was titled 《Discovery of 3-(4-(2-((1H-Indol-5-yl)amino)-5-fluoropyrimidin-4-yl)-1H-pyrazol-1-yl)propanenitrile Derivatives as Selective TYK2 Inhibitors for the Treatment of Inflammatory Bowel Disease》, and you may find the article in Journal of Medicinal Chemistry.Recommanded Product: 1193-21-1 The information in the text is summarized as follows:
The design, synthesis, and structure-activity relationships (SARs) of 3-(4-(2-((1H-indol-5-yl)amino)-5-fluoropyrimidin-4-yl)-1H-pyrazol-1-yl)propanenitrile I [R5= 2-cyanoethyl; R6 = Me, fluoro; R7 = indolin-5-yl, 1-oxoisoindolin-5-yl, 1-tert-butoxycarbonylindol-5-yl, etc.] as selective TYK2 inhibitors was reported. Among them, compound I [R5 = 2-cyanoethyl; R6 = fluoro; R7 = 1-tert-butoxycarbonylindol-5-yl] exhibited acceptable TYK2 inhibition with an IC50 value of 9 nM, showed satisfactory selectivity characteristics over the other three homologous JAK kinases, and performed good functional potency in the JAK/STAT signaling pathway on lymphocyte lines and human whole blood. In liver microsomal assay studied that the clearance rate and half-life of I [R5 = 2-cyanoethyl; R6 = fluoro; R7 = 1-tert-butoxycarbonylindol-5-yl] were 11.4 mL/min/g and 121.6 min, resp. Furthermore, in a dextran sulfate sodium colitis model, I [R5 = 2-cyanoethyl; R6 = fluoro; R7 = 1-tert-butoxycarbonylindol-5-yl] reduced the production of pro-inflammatory cytokines IL-6 and TNF-α and improved the inflammation symptoms of mucosal infiltration, thickening, and edema. Compound I [R5 = 2-cyanoethyl; R6 = fluoro; R7 = 1-tert-butoxycarbonylindol-5-yl] was aselective TYK2 inhibitor and was used to treat immune diseases and deserved further investigation. In the part of experimental materials, we found many familiar compounds, such as 4,6-Dichloropyrimidine(cas: 1193-21-1Recommanded Product: 1193-21-1)
4,6-Dichloropyrimidine(cas: 1193-21-1) is a member of organic chlorides. Organic chloride content in crude oil can be detected through specialized laboratory analysis. Care and attention are essential while sampling and testing.Recommanded Product: 1193-21-1
