  Synthesis of methoxylated goniothalamin, aza-goniothalamin and γ-pyrones and their in vitro evaluation against human cancer cells

  摘要：

  The present work describes the preparation of three novel series of compounds based on the structure of goniothalamin, a natural styryl lactone which has been found to display cytotoxic and antiproliferative activities against a variety of cancer cell lines. A focused library of 29 novel goniothalamin analogues was prepared and evaluated against seven human cancer cell lines. While the gamma-pyrones and the azagoniothalamin analogues were less potent than the lead compound, 2,4-dimethoxy analogue 88 has shown to be more potent in vitro than goniothalamin against all cancer cell lines evaluated. Furthermore, it was more potent than doxorubicin against NCI-ADR/RES, OVCAR-03 and HT-29 while being less toxic to human keratinocytes (HaCat). The 3,5-dimethoxy analogue 90 and 2,4,5-trimethoxy analogue 92 also displayed promising antiproliferative activity when compared to goniothalamin ( 1). These results provide new elements for the design and synthesis of novel representatives of this family of natural compounds. (C) 2012 Elsevier Ltd. All rights reserved.

  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。
