CAS 941685-27-4: 4-(1H-Pyrazol-4-yl)-7-((2-(trimethylsilyl)ethoxy)methyl-7H-pyrrolo[2,3-d]pyrimidine

INCB032304: Key for making Ruxolitinib, a JAK inhibitor, and Barretinib.

4-(1H-Pyrazol-4-yl)-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine is a synthetic compound that can be used to discriminate between the left and right hands of the body. It has been shown to have a high affinity for the enzyme kinases with an IC50 of 0.5 μM. 4-(1H-Pyrazol-4-yl)-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine has been used as a tool in elucidating the mechanism of action of these enzymes by measuring their kinase activity and identifying their substrate specificity. It also has applications in inflammatory diseases as it shifts immune cells from a proinflammatory state to an antiinflammatory state.
