  Further Naphthylcombretastatins. An Investigation on the Role of the Naphthalene Moiety

  摘要：

  By synthesis and biological studies of new naphthalene analogues of combretastatins, we have found that the naphthalene is a good surrogate for the isovanillin moiety (3-hydroxy-4methoxyphenyl) of combretastatin A-4, always generating highly cytotoxic analogues when combined with the 3,4,5-trimethoxyphenyl or related systems. On the other hand, when the naphthalene replaces the 3,4,5-trimethoxyphenyl moiety, the cytotoxic activity is largely decreased. The most cytotoxic naphthalene analogues of combretastatins, which also produce inhibition of tubulin polymerization, exerted their antimitotic effects through microtubule network disruption and subsequent G(2)/M arrest of the cell cycle in human cancer cells.

  日期：——

  A new simple and efficient method for the synthesis of 2-phenylnaphthalenes from electron-rich 1-styryl-2-methoxybenzenes has been described. The reaction proceeds via TFA catalyzed C-C bond cleavage followed by intermolecular [4+2]-Diels-Alder cycloaddition of an in situ formed styrenyl trifluoroacetate intermediate. The quantum chemical calculations identified the transition state for the cycloaddition

  已经描述了一种从富电子的1-苯乙烯基-2-甲氧基苯合成2-苯基萘的简单而有效的新方法。该反应通过TFA催化的CC键裂解进行，然后原位形成的苯乙烯基三氟乙酸酯中间体的分子间[4 + 2] -Diels-Alder环加成反应。量子化学计算确定了环加成反应的过渡态，并有助于追踪反应机理。该方法已被有效地用于合成菲骨架和基于萘的强效选择性ER-β激动剂。

• Design, synthesis, in vitro cytotoxicity evaluation and structure–activity relationship of Goniothalamin analogs
  作者：Mazlin Mohideen、Suraya Zulkepli、Nik-Salmah Nik-Salleh、Mohd Zulkefeli、Jean-Frédéric Faizal Abdullah Weber、A. F. M. Motiur Rahman

  日期：2013.7

  A series of six/five member (E/Z)-Goniothalamin analogs were synthesized from commercially available (3,4-dihydro-2H-pyran-2-yl)methanol/5-(hydroxymethyl)dihydrofuran-2(3H)-one in three steps with good to moderate overall yields and their cytotoxicity against lymphoblastic leukemic T cell line (Jurkat E6.1) have been evaluated. Among the synthesized analogs, (Z)-Goniothalamin appeared to be the most active in cytotoxicity (IC50 = 12 μM). Structure–activity relationship study indicates that introducing substituent in phenyl ring or replacing phenyl ring by pyridine/naphthalene, or decreasing the ring size of lactones (from six to five member) do not increase the cytotoxicity.

  一系列六/五元（E/Z）-钩藤烷类似物从商业可得的（3,4-二氢-2H-吡喃-2-基）甲醇/5-（羟甲基）二氢呋喃-2（3H）-酮在三步反应中被合成，总产率良好至中等，并对它们对淋巴母细胞性白血病T细胞系（Jurkat E6.1）的细胞毒性进行了评估。在合成的类似物中，（Z）-钩藤烷显示出最高的细胞毒性活性（IC50 = 12 μM）。构效关系研究表明，在苯环中引入取代基或用吡啶/萘替换苯环，或者减小内酯环的大小（从六元到五元）并不会增加细胞毒性。
