  Disparate SAR Data of Griseofulvin Analogues for the Dermatophytes Trichophyton mentagrophytes, T. rubrum, and MDA-MB-231 Cancer Cells

  摘要：

  Griseofulvin and 53 analogues of this compound have been tested against the pathogenic dermatophytes Trichophyton rubrum and Trichophyton mentagrophytes as well as against the breast cancer cell line MDA-MB-231. The modifications to griseofulvin include the 4, 5, 6, 2', 3', and 4' positions. The SAR of the griseofulvin analogues toward the two fungi followed the same trend with the majority being less active than griseofulvin and none had more than twice the potency of the parent compound. A comparison of the antifungal the anticancer SAR revealed distinct differences, as the majority of analogues showed increased activity against the cancer cell line MDA-MB-231, highlighted by 2'-benzyloxy-2'-demethoxy-griseofulvin, which showed low activity against both fungi but was among the most potent compounds against MDA-MB-231 cancer cells. Tubulin has been proposed as the target of griseofulvin in both fungal and mammalian cells, but the differences revealed by this SAR study strongly suggest that the mode-of-action of the compound class toward fungi and mammalian cancer cells is different.

  Griseofulvin was identified as an inhibitor of centrosomal clustering in a recently developed assay. Centrosomal clustering is an important cellular event that enables bipolar mitosis for cancer cell lines harboring supernumerary centrosomes. We report herein the synthesis and SAR of 34 griseofulvin analogues as inhibitors of centrosomal clustering. The variations in the griseofulvin structure cover

  在最近开发的测定中，灰黄霉素被鉴定为中心体簇的抑制剂。中心体簇是重要的细胞事件，其使具有过多数量中心体的癌细胞系实现双极有丝分裂。我们在此报道了34个灰黄霉素的类似物的合成和SAR，其为中心体簇的抑制剂。灰黄霉素结构的变化覆盖五个位置，即4、5、2'，3'和4'位置。4和5位的修饰提供了非活性分子。烯醇醚必须位于2'位置，并且4'位置必须为sp 2杂交的。与灰黄霉素相比，活性最高的类似物是2'-苄氧基和2'-（4-甲基苄氧基）类似物，以及前者的肟，其活性增加了25倍。在这项工作中获得的结果与先前报道的皮肤真菌的生长抑制数据的比较显示了相同点和不同点。

  We report two types of modifications to the natural product griseofulvin as strategies to improve solubility and metabolic stability: the conversion of aryl methyl ethers into aryl difluoromethyl ethers at metabolic hotspots and the conversion of the C-ring ketone into polar oximes. The syntheses of the analogues are described together with their solubility, metabolic half-life in vitro and antiproliferative

  我们报告了对天然产物灰黄霉素的两种类型的修饰，以作为提高溶解度和代谢稳定性的策略：在代谢热点将芳基甲基醚转化为芳基二氟甲基醚，以及将C环酮转化为极性肟。描述了类似物的合成及其在两种癌细胞系中的溶解度，体外代谢半衰期和抗增殖作用。我们得出的结论是，总的来说，极性肟的形成是改善类似物性能的最有希望的策略。

  A novel technique to label ortho-, meta-, and para-trimethylsilyl-substituted aryl substituents with radioactive iodide is described. The method takes advantage of the ipso-directing and activating properties of trimethylsilyl substituents on the arenes. The method was demonstrated on a griseofulvin analogue with promising anticancer properties and on lidocaine, a widely used local anesthetic drug
