The authors used structure-based design to discover 2,6-dichloro-4-cyanophenyl and (1R,2R)-2-fluorocyclopropylamide modifications, each of which exhibited improved TYK2 potency and JAK1 and JAK2 selectivity relative to 2,6-dichloro-N-(2-(cyclopropanecarboxamido)pyridin-4-yl)benzamide. Further optimization eventually led to 2-Chloro-4-cyano-6-fluoro-N-(2-((1R,2R)-2-fluorocyclopropanecarboxamido)pyridin-4-yl)benzamide that showed good TYK2 enzyme and interleukin-12 (IL-12) cell potency, as well as acceptable cellular JAK1 and JAK2 selectivity and excellent oral exposure in mice. When tested in a mouse IL-12 PK\/PD model, 2-Chloro-4-cyano-6-fluoro-N-(2-((1R,2R)-2-ffluorocyclopropanecarboxamido)pyridin-4-yl)benzamide showed statistically significant knockdown of cytokine interferon-\u03b3 (IFN\u03b3), suggesting that selective inhibition of TYK2 kinase activity might be sufficient to block the IL-12 pathway in vivo.<\/p>\n<p>Journal of Medicinal Chemistry published new progress about 763120-58-7. 763120-58-7 belongs to pyrazoles-derivatives, auxiliary class Pyrazole,Boronic acid and ester,Boronic Acids,Boronic acid and ester, name is 1H-Pyrazole-4-boronic acid, and the molecular formula is C3H5BN2O2, <a href=\"https:\/\/www.ambeed.com\/products\/763120-58-7.html\">Synthetic Route of 763120-58-7<\/a>.<\/p>\n<p>Referemce:<br \/><a href=\"https:\/\/en.wikipedia.org\/wiki\/Pyrazole\">https:\/\/en.wikipedia.org\/wiki\/Pyrazole<\/a>,<br \/><a href=\"Pyrazole - Wikipedia\">Pyrazoles &#8211;
