  Cardiotonic agents. 5. Fragments from the heterocycle-phenyl-imidazole pharmacophore

  摘要：

  To examine the role of each component in the heterocycle-phenyl-imidazole inotropic pharmacophore, several imidazolone derivatives, an arylimidazole, a substituted 3,4-dihydro-4-oxopyrimidine, and a quinolin-2(1H)-one derivative were prepared as structural fragments or representatives from this relationship. Tests for cardiac inotropic activity in ferret papillary muscle strips (FPM) and for inhibition of crude cAMP phosphodiesterase obtained from canine cardiac tissue suggest that, while all three components contribute significantly toward potent activity (active at less than 1 microM concentrations in FPM), any combination of two components, in approximately a preferred geometry, represents the minimal requirements for weak activity (active at less than 25 microM concentrations). No single component appears to be requisite in an absolute sense.

  Bromodomain and extra‐terminal domain (BET) inhibitors are widely used both as chemical tools to study the biological role of their targets in living organisms and as candidates for drug development against several cancer variants and human disorders. However, non‐BET bromodomains such as those in p300 and CBP are less studied. XDM‐CBP is a highly potent and selective inhibitor for the bromodomains

  溴结构域和末端外域（BET）抑制剂被广泛用作研究其靶标在活生物体中的生物学作用的化学工具，也被用作针对几种癌症变体和人类疾病的药物开发的候选物。但是，对非BET溴结构域（例如p300和CBP中的结构域）的研究较少。XDM-CBP是对CBP和p300溴结构域的高效选择性抑制剂，该抑制剂来自全选择性BET BRD结合片段。结合X射线晶体结构分析和热力学分析，XDM-CBP被用于体外筛选几种癌细胞系，以研究其对癌细胞增殖的抑制潜力。XDM-CBP被证明是一种有效的选择性CBP / p300抑制剂，可作用于特定的癌细胞系，特别是恶性黑色素瘤，乳腺癌和白血病。

• Synthesis of pyrazine via chemoselective reduction of β-keto-α-oximino ester using baker’s yeast

  The synthesis of pyrazines by the baker's yeast-mediated reaction of beta-keto-alpha-oximino esters and amides is described. Baker's yeast reduced oximes selectively over ketones of beta-keto-alpha-oximino esters to give the corresponding beta-keto-alpha-amino ester intermediates, which underwent spontaneous dimerization followed by air-induced aromatization to yield pyrazines. The chemoselective reduction of beta-keto-alpha-oximino amides using baker's yeast also afforded the corresponding pyrazines. Interestingly, both hydroximes and alkoximes gave the pyrazines by the baker's yeast-mediated reduction via the corresponding amino ketones, the known precursors of pyrazines. The reaction was strongly dependent upon pH of reaction medium, and gave optimum yields at pH 5. These results demonstrate that pyrazines were synthesized efficiently and eco-friendly using a whole-cell biocatalytic system as an alternative to chemical reduction. (C) 2015 Elsevier B.V.
