Specifically, the invention discloses the compounds represented by a formula (I) shown in the specification, enantiomers, diastereomers, racemates or a mixture of the compounds, or a pharmaceutically acceptable salt, hydrate and solvate of the compounds, a preparation method of the above materials, and applications of the above materials in preparation of an ASK1 small molecule inhibitor, or medicines for preventing and/or treating diseases related to ASK1, especially liver diseases, lung diseases, cardiovascular diseases, kidney diseases and metabolic diseases.
Highly efficient monophosphine-based catalyst for the palladium-catalyzed Suzuki-Miyaura reaction of heteroaryl halides and heteroaryl boronic acids and esters
Billingsley, Kelvin,Buchwald, Stephen L.
, p. 3358 - 3366 (2007/10/03)
A highly active and efficient catalyst system derived from a palladium precatalyst and monophosphine ligands 1 or 2 for the Suzuki-Miyaura cross-coupling reaction of heteroaryl boronic acids and esters has been developed. This method allows for the preparation of a wide variety of heterobiaryls in good to excellent yields and displays a high level of activity for the coupling of heteroaryl chlorides as well as hindered aryl and heteroaryl halides. Specific factors that govern the efficacy of the transformation for certain heterocyclic motifs were also investigated.
N-(Lower-alkyl)-N'-[5-(pyridinyl)-2-pyridinyl]ureas and cardiotonic use thereof
-
, (2008/06/13)
N-R1 -N-(6-R-5-PY-2-pyridinyl)ureas, where R1 is lower-alkyl, R is hydrogen or lower-alkyl, and PY is 4- or 3-pyridinyl or 4- or 3-pyridinyl having one or two lower-alkyl substituents, or acid-addition salts thereof. Said compounds (I) or pharmaceutically acceptable acid-addition salts thereof are useful as cardiotonic agents. The preparation and cardiotonic use of said compounds are shown.
