  (E)-4-Aryl-4-oxo-2-butenoic acid amides, chalcone–aroylacrylic acid chimeras: Design, antiproliferative activity and inhibition of tubulin polymerization

  摘要：

  Antiproliferative activity of twenty-nine (E)-4-aryl-4-oxo-2-butenoic acid amides against three human tumor cell lines (HeLa, FemX, and K562) is reported. Compounds showed antiproliferative activity in one-digit micromolar to submicromolar concentrations. The most active derivatives toward all the cell lines tested bear alkyl substituents on the aroyl moiety of the molecules. Fourteen compounds showed tubulin assembly inhibition at concentrations <20 mu M. The most potent inhibitor of tubulin assembly was unsubstituted compound 1, with IC50 = 2.9 mu M. Compound 23 had an oral LD50 in vivo of 45 mg/kg in mice. Cell cycle analysis on K562 cells showed that compounds 1, 2 and 23 caused accumulation of cells in the G2/M phase, but inhibition of microtubule polymerization is not the principal mode of action of the compounds. Nevertheless, they may be useful leads for the design of a new class of antitubulin agents. (C) 2013 Elsevier Masson SAS. All rights reserved.

  Intra- and intermolecular thermal transformations of 2-acyl- and 2-alkoxycarbonyl-N-phthalimidoaziridines

  摘要：

  Heating 2-acyl- and 2-alkoxycarbonyl-N-phthalimidoaziridines leads to substituted oxazoles in 45-65% yield. Only esters of oxazolecarboxylic acids are formed when the aziridine contains acyl and alkoxy groups. The thermolysis of the same aziridines in the presence of N-phenylmaleimide and the dimethyl ester of acetylenedicarboxylic acid gives both oxazoles and the products of 1,3-dipolar cycloaddition from aziridines with two substituents at the carbon atoms but only oxazoles from trisubstituted aziridines.

• Alkylating prazosin analog: irreversible label for .alpha.1-adrenoceptors

  A series of prazosin analogues comprised of N-acyl derivatives of N'-(4-amino-6,7-dimethoxyquinazolin-2-yl)piperazine was prepared and the nature of their binding to alpha 1-adrenoceptors was investigated. Derivatives with alpha, beta-unsaturated acyclic acyls had some affinity but no irreversible action at the receptor. Other potent compounds, also without irreversible activity, contained cinnamoyl

  制备了一系列由N'-（4-氨基-6,7-二甲氧基喹唑啉-2-基）哌嗪的N-酰基衍生物组成的哌唑嗪类似物，并研究了它们与α1-肾上腺素受体结合的性质。具有α，β-不饱和无环酰基的衍生物具有一些亲和力，但对受体没有不可逆作用。其他有效的化合物，也具有不可逆的活性，含有肉桂酰基或（苯基氨基）硫代羰基残基。用双环[2.2.2] octa-2,5-二烯-2-基羰基衍生物获得高亲和力和不可逆结合。该化合物中的共轭双键与药效基团的位置和距离与上述某些高亲和力化合物中的位置和距离大致相同，但没有不可逆作用。认为不可逆转的封锁涉及两个连续的识别步骤：分子的药效团部分与受体的结合位点可逆结合，然后化学活性部分与受体的相邻亲核试剂反应。目前的结果表明，要使第二步有效进行，即使在分子的化学活性部分中也必须存在对受体的一定亲和力。受体的结合和亲核位点的简单跨度不足。
