  Synthesis of Xanthohumol Analogues and Discovery of Potent Thioredoxin Reductase Inhibitor as Potential Anticancer Agent

  摘要：

  The selenoprotein thioredoxin reductases (TrxRs) are attractive targets for anticancer drugs development. Xanthohumol (Xn), a naturally occurring polyphenol chalcone from hops, has received increasing attention because of its multiple pharmacological activities. We synthesized Xn and its 43 analogues and discovered that compound 13n displayed the highest cytotoxicity toward HeLa cells (IC50 = 1.4 mu M). Structure-activity relationship study indicates that the prenyl group is not necessary for cytotoxicity, and introducing electron-withdrawing group, especially on the meta-position, is favored. In addition, methylation of the phenoxyl groups generally improves the potency. Mechanistic study revealed that 13n selectively inhibits TrxR and induces reactive oxygen species and apoptosis in HeLa cells. Cells overexpressing TrxR are resistant to 13n insult, while knockdown of TrxR sensitizes cells to 13n treatment, highlighting the physiological significance of targeting TrxR by 13n. The clarification of the structural determinants for the potency would guide the design of novel potent molecules for future development.

  A general strategy for the synthesis of 30-prenylated chalcones was established and a series of prenylated hydroxychalcones, including the hop (Humulus lupulus L.) secondary metabolites xanthohumol (1), desmethylxanthohumol (2), xanthogalenol (3), and 4-methylxanthohumol (4) were synthesized. The influence of the A-ring hydroxylation pattern on the cytotoxic activity of the prenylated chalcones was investigated in a HeLa cell line and revealed that non-natural prenylated chalcones, like 2',3,4',5-tetrahydroxy-6'-methoxy-3'-prenylchalcone (9, IC50 3.2 +/- 0.4 mu M) as well as the phase 1 metabolite of xanthohumol (1), 3-hydroxyxanthohumol (8, IC50 2.5 +/- 0.5 mu M), were more active in comparison to 1 (IC50 9.4 +/- 1.4 mu M). A comparison of the cytotoxic activity of xanthohumol (1) and 3-hydroxyxanthohumol (8) with the non-prenylated analogs helichrysetin (12, IC50 5.2 +/- 0.8) and 3-hydroxyhelichrysetin (13, IC50 14.8 +/- 2.1) showed that the prenyl side chain at C-3' has an influence on the cytotoxicity against HeLa cells only for the dihydroxylated derivative. This offers interesting synthetic possibilities for the development of more potent compounds. The ORAC activity of the synthesized compounds was also investigated and revealed the highest activity for compounds 12, 4'-methylxanthohumol (4), and desmethylxanthohumol (2), with 4.4 +/- 0.6, 3.8 +/- 0.4, and 3.8 +/- 0.5 Trolox equivalents, respectively.
