Discovery of 1-amino-5 H-pyrido[4,3-b]indol-4-carboxamide inhibitors of janus kinase 2 (JAK2) for the treatment of myeloproliferative disorders

The JAK-STAT pathway mediates signaling by cytokines, which control survival, proliferation, and differentiation of a variety of cells. In recent years, a single point mutation (V617F) in the tyrosine kinase JAK2 was found to be present with a high incidence in myeloproliferative disorders (MPDs). This mutation led to hyperactivation of JAK2, cytokine-independent signaling, and subsequent activation of downstream signaling networks. The genetic, biological, and physiological evidence suggests that JAK2 inhibitors could be effective in treating MPDs. De novo design efforts of new scaffolds identified 1-amino-5H-pyrido[4,3-b]indol-4-carboxamides as a new viable lead series. Subsequent optimization of cell potency, metabolic stability, and off-target activities of the leads led to the discovery of 7-(2-aminopyrimidin-5-yl)-1- {[(1R)-1-cyclopropyl-2,2,2-trifluoroethyl]amino}-5H-pyrido[4,3-b] indole-4-carboxamide (65). Compound 65 is a potent, orally active inhibitor of JAK2 with excellent selectivity, PK profile, and in vivo efficacy in animal models.

A novel class of 2-fluoro-6-O-propargyl-11,12-carbamate ketolide derivatives of erythromycin has been synthesized for antibacterial SAR studies. Replacement of the C2-hydrogen by a fluorine atom allows the synthesis of 6-O-propargylic ketones and electron-deficient 6-O-propargylic aromatic derivatives by preventing intramolecular C2-enolate Michael cyclization.

Synthesis of Isomerically Pure (Z)-Alkenes from Terminal Alkynes and Terminal Alkenes: Silver-Catalyzed Hydroalkylation of Alkynes

Alkenes are an important class of compounds common among biologically active molecules and often are used as intermediates in organic synthesis. Many alkenes exist in two stereoisomeric forms (E and Z), which have different structures and different properties. The selective formation of the two isomers is an important synthetic goal that has long inspired the development of new synthetic methods. However, the efficient synthesis of diastereopure, thermodynamically less stable, Z-alkenes is still challenging. Here, we demonstrate an efficient synthesis of diastereopure Z-alkenes (Z:E > 300:1) through a silver-catalyzed hydroalkylation of terminal alkynes, using alkylboranes as coupling partners. We also describe the exploration of the substrate scope, which reveals the broad functional group compatibility of the new method. Preliminary mechanistic studies suggest that a 1,2-metalate rearrangement of the silver borate intermediate is the key step responsible for the stereochemical outcome of the reaction.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 17321-29-8, help many people in the next few years.Safety of 3-Bromo-6-methoxypyridazine
