  1,4-Dihydropyridines bearing a pharmacophoric fragment of lidoflazine

  摘要：

  A series of 1,4-dihydropyridines bearing a pharmacophoric fragment of Iidoflazine was synthesized. The compounds were evaluated for inotropic, chronotropic, and calcium antagonist activities. All compounds behave as inotropic and chronotropic agents, except for compounds 4b, 5a, and 5b, which exibit a rather weak calcium antagonism in vascular smooth muscle (like aorta). Compound 5b is about twofold more potent in decreasing both chronotropy and inotropy, while compound 5c is about fivefold more potent in decreasing inotropy than nifedipine. Moreover, compound 5b is the most potent calcium antagonist derivative of the series. Copyright (C) 1996 Elsevier Science Ltd

  Dimeric 1,4-dihydropyridines as calcium channel antagonists

  摘要：

  A series of 1,n-alkanediylbis(1,4-dihydropyridines) (n = 2, 4, 6, 8, 10, 12) bridged at C3 of 2,6-dimethyl-3-carboxy-5-carbethoxy-4-(3-nitrophenyl)-1,4-dihydropyridin e were synthesized and evaluated in a radioligand binding assay, [3H]nitrendipine in intestinal smooth muscle, as Ca2+ channel ligands. Binding activity was comparable to that of nitrendipine itself but independent of chain length, suggesting the lack of a major binding contribution by the second 1,4-dihydropyridine group. Analogues lacking the second 1,4-dihydropyridine nucleus or possessing an inactive function (4-nitrophenyl) were no less active, confirming that this series of ligands likely does not bridge adjacent 1,4-dihydropyridine receptors of the Ca2+ channel.

  Palladium-catalyzed denitrative Suzuki coupling of nitroarenes using 2-aryl-5-(2,4,6-triisopropylphenyl)-2,3-imidazolylidene[1,5-a]pyridines as the ligands is described. The key to success is the use of the NHC ligands which show strong donating ability and suitable steric hindrance allowing the successful oxidative addition of Ar–NO2 bonds. Both aromatic and aliphatic boronic acids are tolerated,

  sugar mixtures (LMMs) were synthesized and used for preparation of 1,4-dihydropyridines with aldehydes, 1,3-dicarbonyl compounds, and a nitrogen source as starting materials. Good yields, low reaction times, recyclability of LMMs, and catalyst-free methodology are some of the highlights of this new protocol. GRAPHICAL ABSTRACT
