• 1,4-Dihydropyridines as antagonists of platelet activating factor. 1. Synthesis and structure-activity relationships of 2-(4-heterocyclyl)phenyl derivatives

  日期：1992.8

  A novel class of 2-(4-heterocyclylphenyl)-1,4-dihydropyridines (2-38) possessing antagonist activity against platelet activating factor (PAF) was prepared by the Hantzsch synthesis from a variety of ethyl 4'-heterocyclic-substituted benzoylacetates, aryl or heteroaryl aldehydes, and substituted 3-aminocrotonamides or 3-aminocrotonate esters. Structure-activity relationships were evaluated where PAF

  Starting from a weak screening hit, potent and selective inhibitors of the MALT1 protease function were elaborated. Advanced compounds displayed high potency in biochemical and cellular assays. Compounds showed activity in a mechanistic Jurkat T cell activation assay as well as in the B-cell lymphoma line OCI-Ly3, which suggests potential use of MALT1 inhibitors in the treatment of autoimmune diseases

  从筛选力较弱的角度出发，详细介绍了MALT1蛋白酶功能的有效和选择性抑制剂。先进的化合物在生化和细胞分析中显示出很高的效价。化合物在机制性Jurkat T细胞活化试验以及B细胞淋巴瘤细胞系OCI-Ly3中显示出活性，这表明MALT1抑制剂在治疗自身免疫性疾病以及NF-κB失调的B细胞淋巴瘤方面有潜在用途。 κB途径。最初，该化合物系列的大鼠药代动力学特性主要由很高的清除率决定，该清除率可能与酰胺裂解有关。使用大鼠肝细胞分析可以建立良好的体外-体内相关性，从而鉴定出具有改善的PK特性的化合物。

  ortho-Quinone methides are useful transient synthetic intermediates in organic synthesis. These species are most often generated in situ by the acid- or base-mediated transformation of phenols that have been pre-functionalized at a benzylic position, or by biomimetic oxidation of the corresponding ortho-alkylphenols with metal oxidants or transition-metal complexes. Here we describe a method for the
