  • Condensation reactions of (1E,3E)-4-amino-3-cyano-4-methoxy-1-phenyl-2-azabutadiene and electrocyclizations of diazatrienes
    作者:Fillmore Freeman、Darrick S. H. L. Kim

    日期:1992.1
    (1E,3E)-4-Amino-3-cyano-4-methoxy-1-phenyl-2-azabutadiene (2) reacts with 2-methoxypropene in refluxing methylbenzene in the presence of catalytic pyridinium p-toluenesulfonate (PPTS) to give 2-cyano-5,5-dimethyl-3-methoxy-6-phenyl-4,5-dihydro-1,4-diazabenzene (5). Similarly, 2-aza-1,3-butadiene 2 reacts with triethyl orthoformate and triethyl orthobenzoate to give 3-cyano-2-methoxy-5-phenyl-1,4-diazabenzene (6) and 2-cyano-3-methoxy-5,6-diphenyl-1,4-diazabenzene (7), respectively. The PPTS-catalyzed reaction of 2 with triethyl orthoacetate gives 2-cyano-3-methoxy-5-methyl-6-phenyl-1,4-diazabenzene (8) and 2-cyano-5-ethoxy-3-methoxy-5-methyl-6-phenyl-4,5-dihydro-1,4-diazabenzene (9). Phenylmethanal and (2-thienyl)methanal react with 2-aza-1,3-butadiene 2 to give 5-methoxy-2,3-diphenyl-1,4-diazabenzene (17) and 5-methoxy-2-phenyl-3-(2-thienyl)-1,4-diazabenzene (18), respectively. Diazatrienes (enediimines) are proposed as the intermediates undergoing six pi-electron electrocyclizations to 1,4-diazabenzenes (dihydropyrazines, pyrazines, and pyrazinecarbonitriles).

    F-box protein S-phase kinase-associated protein 2 (Skp2) is a component of cullin-RING ligases, which is responsible for recruiting and ubiquitinating substrates and subsequently plays its proteolytic and non-proteolytic role. High expression of Skp2 is frequently observed in multiple aggressive tumor tissues and associated with poor prognosis. Several of the Skp2 inhibitors have been reported in the
    F-box 蛋白 S 相激酶相关蛋白 2 (Skp2) 是 cullin-RING 连接酶的组成部分,负责招募和泛素化底物,随后发挥其蛋白解和非蛋白解作用。Skp2 的高表达经常在多种侵袭性肿瘤组织中观察到,并且与不良预后相关。在过去的几十年里,已经报道了几种 Skp2 抑制剂;然而,其中很少有显示出详细的结构-活性关系(SAR)和有效的生物活性。在此,基于我们内部库中的热门化合物11a ,我们优化并合成了一系列针对Skp2-Cks1相互作用的新型2,3-二苯基吡嗪抑制剂,并进一步系统地研究了SAR。其中,化合物14i显示出针对 Skp2–Cks1 相互作用的有效活性,IC 50值为 2.8 μM,针对 PC-3 和 MGC-803 细胞,IC 50值分别为 4.8 和 7.0 μM。最重要的是,化合物14i对PC-3和MGC-803异种移植小鼠模型表现出有效的抗癌作用,且没有明显的毒性。
  • Measurement and prediction of hydrophobicity parameters for highly lipophilic compounds: Application of the HPLC column-switching technique to measurement of log P of diarylpyrazines

    In the preparatory stage of structure-activity relationship (QSAR) studies of anti-platelet aggregant pyrazine derivatives, log P values (P: 1-octanol/water partition coefficient) of diarylpyrazines were measured by a newly developed HPLC column-switching technique. The system consists of two processes: (1) adsorption of the sample at the top end of a short precolumn, and then (2) quantifying the enriched analyte by a conventional analytical column. By using the log P values thus obtained, the correction factor for the steric hindrance caused by the vicinal diphenyl groups was estimated. The log k values (k; retention factor) were also measured with methanol-buffer (pH 7.4) eluents and related to log P. The eluent of 50% methanol content (M50) gave a good linear relationship over a wide range of log P (-0.3< log P < 5.2), indicating that log k(M50) parameter is useful for predicting the log P value.
