Discovery of 1-Amino-5H-pyrido[4,3-b]indol-4-carboxamide Inhibitors of Janus Kinase 2 (JAK2) for the Treatment of Myeloproliferative Disorders
摘要:
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 JAK.2, 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.

Synthesis and Biological Evaluation of Pyrrolinic Isosteres of Rilmenidine. Discovery of <i>cis</i>-/<i>trans</i>-Dicyclopropylmethyl-(4,5-dimethyl-4,5-dihydro-3<i>H</i>- pyrrol-2-yl)-amine (LNP 509), an I<sub>1</sub> Imidazoline Receptor Selective Ligand with Hypotensive Activity
detectable affinity at alpha2ARs yet was capable of lowering blood pressure after central administration. These pyrrolinic analogues constitute a new chemical class of imidazoline related compounds with high selectivity for the I1Rs. They could be used as new tools in the study of I1Rs and in the conception of new centrallyacting hypotensive drugs.
