Discovery of 2-arylamino-4-(1-methyl-3-isopropylsulfonyl-4-pyrazol-amino)pyrimidines as potent anaplastic lymphoma kinase (ALK) inhibitors
摘要:
A new series of 2,4-diamino pyrimidine derivatives with a sulfone-substituted pyrazole right side-chain were discovered as potent anaplastic lymphoma kinase inhibitors. Structure-activity relationship of the left side-chain on phenyl substitutions were explored which delivered many potent ALK inhibitors. Among them, 29a showed favorable pharmacokinetic profiles in rats and dogs together with significant antitumor efficacy in EML4-ALK fusion xenograft model. (C) 2015 Elsevier Ltd. All rights reserved.

We report here the synthesis of nitropyrazoles in good to excellent yields from iodopyrazoles over silica-sulfuric acid catalyst for the first time. The present procedure require less acid, offers a simplified workup procedure, and may be applied for the nitration of a wide variety of iodoazoles in drug and pharmaceutical industries.

Nitrodeiodination of iodopyrazoles using nitric acid/Faujasite has been investigated. The present procedure is simple, rapid and convenient and requires no sulfuric acid or oleum and may be applied for the synthesis of several nitropyrazoles in good yields in drug and pharmaceutical industries.
