  Synthesis and evaluation of cytotoxic effects of hanultarin and its derivatives

  摘要：

  One of the known cytotoxic lignans is (-)-1-O-feruloyl-secoisolariciresinol designated as hanultarin, which was isolated from the seeds of Trichosanthes kirilowii. In this Letter, we described the first synthesis of 1-O-feruloyl-secoisolariciresinol, 1,4-O-diferuloyl-secoisolariceresinol and their analogues. The cytotoxicities of these compounds were evaluated against several cancer cell lines. Interestingly, we found that the feruloyl diester derivative of secoisolariciresinol was the most active cytotoxic compound against all the cancer cells tested in this experiment. The IC(50) values of the 1,4-O-diferuloyl-secoisolariceresinol were in the range of 7.1-9.8 mu M except one cell line. In considering that both ferulic acid and secoisolariciresinol are commonly found in many plants and have no cytotoxicity, this finding is remarkable in that simple covalent bonds between the ferulic acid and secoisolariciresinol cause a cytotoxic effect.

  Secoisolariciresinol diglucosides (SDGs) (S,S)-SDG-1 (major isomer in flaxseed) and (R,R)-SDG-2 (minor isomer in flaxseed) were synthesized from vanillin via secoisolariciresinol (6) and glucosyl donor 7 through a concise route that involved chromatographic separation of diastereomeric diglucoside derivatives (S,S)-8 and (R,R)-9. Synthetic (S,S)-SDG-1 and (R, R)-SDG-2 exhibited potent antioxidant properties (EC50 = 292.17 +/- 27.71 mu M and 331.94 +/- 21.21 mu M, respectively), which compared well with that of natural (S,S)-SDG-1 (EC50 = 275.24 +/- 13.15 mu M). These values are significantly lower than those of ascorbic acid (EC50 = 1129.32 +/- 88.79 mu M) and a-tocopherol (EC50 = 944.62 +/- 148.00 mu M). Compounds (S,S)SDG-1 and (R, R)-SDG-2 also demonstrated powerful scavenging activities against hydroxyl [natural (S,S)-SDG-1: 3.68 +/- 0.27; synthetic (S,S)-SDG-1: 2.09 +/- 0.16; synthetic (R,R)-SDG-2: 1.96 +/- 0.27], peroxyl [natural (S,S)-SDG-1: 2.55 +/- 0.11; synthetic (S,S)-SDG-1: 2.20 +/- 0.10; synthetic (R,R)-SDG-2: 3.03 +/- 0.04] and DPPH [natural (S, S)-SDG-1: EC50 = 83.94 +/- 2.80 mu M; synthetic (S, S)-SDG-1: EC50 = 157.54 +/- 21.30 lM; synthetic (R, R)-SDG-2: EC50 = 123.63 +/- 8.67 mu M] radicals. These results confirm previous studies with naturally occurring (S,S)-SDG-1 and establish both (S, S)-SDG-1 and (R,R)-SDG-2 as potent antioxidants and free radical scavengers for potential in vivo use.
