PI3K INHIBITORS AND METHODS OF MAKING AND USING THE SAME
摘要:
The disclosure is in part directed to solid forms of (S)-N-(8-(2-chloro-5-fluorophenyl)-3-(methylcarbamoyl)-6-oxo-5,6,7,8-tetrahydroimidazo[1,5-a]pyrazin-1-yl)benzo[d]isothiazole-3-carboxamide, its salts, its crystalline forms, and variants thereof.
An efficient copper-catalyzed method for the synthesis of quinolinones, pyridinones, and heteroannulated pyridinones via cascade reactions of substituted 2-iodo-, 2-bromo-, and 2-chlorobenzocarbonyls with 2-arylacetamides is reported. The protocol works well for the reaction of most of the 2-iodo-, 2-bromo- and 2-chlorobenzocarbonyls with 2-arylacetamides. copper iodide - diamines - cascade reactions

JanusKinase 2 (JAK2) is a kind of intracellular non-receptor protein tyrosine kinase and has been certified as an important target for the treatment of myeloproliferative neoplasms and rheumatoid arthritis. However, the low selectivity and potential safety issues restrict the clinical applications of JAK2 inhibitors. Here we found that crizotinib showed good inhibitory activity against JAK2 by enzymatic

the design, synthesis, and biologicalevaluation of a series of 2-aminopyridine derivatives. The results of enzymatic activity assays supported compound 16m-(R) as a potential and selective JAK2 inhibitor, which exhibited high inhibitory activity with an IC50 of 3 nM against JAK2, and 85- and 76-fold selectivity over JAK1 and JAK3, respectively. Structure-activity relationships (SAR) and mechanistic
The reinvestigation of acylation reactions of fluorinated aryl methylketones with ethyl esters at 0°C afforded fluorinated 1, 3-diketones in excellent yields.
