Synthesis of novel N-aryl-2,5-dihydro-2-iminofuran-3-carboxamides and their chemical transformations
摘要:
Novel N-aryl-2,5-dihydro-2-iminofuran-3-carboxamides have been synthesized by condensation of tertiary alpha-hydroxyketones with N-aryl-2-cyanoacetamides. The obtained products were transformed to corresponding iminium chlorides, hydrogen sulfates, 2-oxo and 2-(dicyanomethylene) derivatives. All new compounds were characterized by NMR and IR spectral data and elemental analysis.
The problem of the present invention is to provide a pigment dispersant that exhibits high heat resistance while achieving dispersibility for a wide range of organic pigments. Another object of the present invention is to provide a color filter coloring composition that exhibits high contrast ratio and brightness even when containing organic pigments at high concentrations, and further exhibits high alkali resistance (developability). Furthermore, the objective of the present invention is to provide a high-quality color filter that achieves high contrast ratio and brightness, as well as good developability and adhesion.
The above problems are solved by a color filter coloring composition containing organic pigments, a pigment dispersant having a specific isoindoline skeleton represented by general formula (1), binder resin, and organic solvent.

The InhA inhibitors play key role in mycolic acid synthesis by preventing the fatty acid biosynthesis pathway. In this present article, Pharmacophore modelling and molecular docking study followed by in silico virtual screening could be considered as effective strategy to identify newer enoyl-ACP reductase inhibitors. Pyrrolidine carboxamide derivatives were opted to generate pharmacophore models using
InhA抑制剂通过阻止脂肪酸的生物合成途径在霉菌酸的合成中起关键作用。在本文中,药理学建模和分子对接研究,然后进行计算机虚拟筛选,可以被认为是识别新型烯酰-ACP还原酶抑制剂的有效策略。在Discovery Studio 2.1中,使用HypoGen算法选择了吡咯烷羧酰胺衍生物来生成药效团模型。此外,它还被用于筛选Zinc和Minimaybridge数据库,以鉴定和设计更新的有效命中分子。进一步评估检索到的较新命中品的药物相似性,并将其与烯酰基酰基载体蛋白还原酶对接。在这里,新颖的吡唑并[1,5-a]嘧啶类似物被设计并以高收率合成。通过IR,MASS,1H-NMR,13C-NMR光谱对合成的最终分子进行结构解析,并使用Microplate Alamar蓝法(MABA)方法进一步测试了其对H37Rv菌株的体外抗结核活性。大多数合成的化合物显示出强大的抗结核活性。此外,对这些有效化合物进行了M
