    摘要:
    组蛋白去乙酰化酶 (HDAC) 是临床验证和有吸引力的人类癌症表观遗传药物靶点。迄今为止,有几种HDAC抑制剂已被批准用于癌症治疗,但由于HDAC抑制剂的药代动力学、生物利用度和选择性较差,临床应用受到限制,其中大多数需要与其他药物联合使用才能达到更好的效果。在这里,我们描述了我们为发现一系列新的内酰胺衍生物作为选择性 HDAC 抑制剂所做的努力。密集的结构修饰导致化合物24g被鉴定为最活跃的 I 类 HDAC 抑制剂,以及令人满意的体外代谢稳定性 (t 1/2, 人类 = 797 分钟) 和理想的口服生物利用度 (F = 92%)。更重要的是,化合物24g在TMD-8异种移植模型(TGI = 77%)中显示出良好的抗肿瘤功效,且无明显毒性。这些结果表明 I 类 HDAC 抑制剂可能潜在地用于治疗某些弥漫性大 B 细胞淋巴瘤疗法。

  • SpinPhox/Iridium(I)-Catalyzed Asymmetric Hydrogenation of Cyclic α-Alkylidene Carbonyl Compounds
    作者:Xu Liu、Zhaobin Han、Zheng Wang、Kuiling Ding

    日期:2014.2.10
    cyclic carbonyl compounds bearing an αchiral carbon center are of interest in pharmaceutical sciences and asymmetric synthesis. Herein, SpinPhox/IrI catalysts have been demonstrated to be highly enantioselective in the asymmetric hydrogenation of the CC bonds in the exocyclic α,βunsaturated cyclic carbonyls, including a broad range of α‐alkylidene lactams, unsaturated cyclic ketones, and lactones.

    ether ligands have been tested in the Ir-catalyzed asymmetric hydrogenation of a range of olefins (50 substrates in total). The presented ligands are synthesized in three steps from cheap indene and they are air-stable solids. Their modular architecture has been crucial to maximize the catalytic performance for each type of substrate. Improving most Ir-catalysts reported so far, this ligand family

  • Natural α-methylenelactam analogues: Design, synthesis and evaluation of α-alkenyl-γ and δ-lactams as potential antifungal agents against Colletotrichum orbiculare
    作者:Wang Delong、Wang Lanying、Wu Yongling、Song Shuang、Feng Juntao、Zhang Xing

    日期:2017.4
    In our continued efforts to improve the potential utility of the alpha-methylene-gamma-lactone scaffold, 62 new and 59 known natural alpha-methylenelactam analogues including alpha-methylene-gamma- lactams, alpha-arylidene- gamma and delta-lactams, and 3-arylideneindolin-2-ones were synthesized as the bioisosteric analogues of the amethylenelactone scaffold. The results of antifungal and cytotoxic activity indicated that among these derivatives compound (E)-1-(2, 6-dichlorobenzyl)-3-(2-fluorobenzylidene) pyrrolidin-2-one (Py51) possessed good selectivity with the highest antifungal activity against Colletotrichum orbiculare with IC50 - 10.4 mu M but less cytotoxic activity with IC50 - 141.2 mu M (against HepG2 cell line) and 161.2 mu M ( against human hepatic L02 cell line). Ultrastructural change studies performed by transmission electron microscope showed that Py51 could cause important cell morphological changes in C. orbiculare, such as plasma membrane detached from cell wall, cell wall thickening, mitochondria disruption, a dramatic increase in vacuolation, and eventually a complete loss in the integrity of organelles. Significantly, mitochondria appeared one of the primary targets, as confirmed by their remarkably aberrant morphological changes. Analysis of structureeactivity relationships revealed that incorporation of the aryl group into the alpha-exo methylene and the N-benzyl substitution increased the activity. Meanwhile, the alpha-arylidene-gamma-lactams have superiority in selectivity over the 3-arylideneindolin-2-ones. Based on the results, the N- benzyl substituted a-(2-fluorophenyl)-gamma-lactam was identified as the most promising natural- based scaffold for further discovering and developing improved crop- protection agents.

  • Enantioselective Hydrogenation of 3-Alkylidenelactams:  High-Throughput Screening Provides a Surprising Solution
    作者:Tai-Yuen Yue、William A. Nugent
    DOI:10.1021/ja028043y
    日期:2002.11.1
    High-throughput screening of 256 potential catalysts (8 metal precursors x 32 phosphine ligands) has identified [(BDPP)Ir(COD)]BF4 as a catalyst for the enantioselective hydrogenation of 3-alkylidenelactams. This result is surprising given the highly flexible backbone of the BDPP ligand and the ineffectiveness of this catalyst in other applications. The asymmetric hydrogenation appears fairly general for five- and six-membered lactams and in one case has been scaled up to a 20 kg level.
  • Synthesis of substituted (α-methylene lactams by rhodium catalysed carbonylation of acetylenic amines
    作者:Eva M. Campi、J.Michael Chong、W.Roy Jackson、Marcel Van Der Schoot

    日期:1994.2
    Reactions of gamma- and beta-aminoalkynes, (2) and (5) with hydrogen and carbon monoxide in the presence of rhodium catalysts give substituted alpha-methylene-2-piperidinones (7) and 2-pyrrolidinones (11).
