  名称：

  Antiproliferative, antiandrogenic and cytotoxic effects of novel caffeic acid derivatives in LNCaP human androgen-dependent prostate cancer cells

  摘要：

  Caffeic acid and its naturally occurring derivative caffeic acid phenethyl ester (CAPE) have antiproliferative and cytotoxic properties in a variety of cancer cell lines without displaying significant toxicity toward healthy cells, and are considered to be potential anticancer agents. However, little is known about their effects on prostate cancer cells. We synthesized and evaluated the effects of caffeic acid, CAPE (2) and 18 synthetic derivatives on cell viability and androgen-dependent cell proliferation, subcellular localisation and expression of androgen receptor (AR) and secretion of prostate-specific antigen (PSA) in LNCaP human hormone-dependent prostate cancer cells. Several synthetic derivatives of CAPE were strong, concentration-dependent cytotoxic agents in LNCaP cells with IC50 values in the 6.8-26.6 mu M range, potencies that were up to five-fold greater than that of CAPE (33.7 +/- 4.0 mu M). A number of caffeic acid derivatives were inhibitors of androgen-stimulated LNCaP cell proliferation with concomitant inhibition of DHT-stimulated PSA secretion. Compound 24 was the most cytotoxic and antiproliferative caffeic acid derivative (IC50 values of 6.8 +/- 0.3 and 2.4 +/- 0.8 mu M, respectively) inhibiting DHT-stimulated cell proliferation and PSA secretion statistically significantly at concentrations as low as 0.3 mu M. Exposure to DHT increased cytoplasmic and nuclear AR levels and co-treatment with increasing concentrations of compound 24 or CAPE (2), notably, further increased these levels. In conclusion, a number of synthetic derivatives of caffeic acid are potent inhibitors of androgen-dependent prostate cancer cell proliferation and viability, acting, at least in part, via an antiandrogenic mechanism that involves increased nuclear accumulation of (presumably inactive) AR.

  In screening experiments for rat intestinal α-glucosidase (sucrase and maltase) inhibitors in 325 plants cultivated in Japan’s southern island, of Tanegashima, marked inhibition against both sucrase and maltase was found in the extract of the fruit of Solanum torvum. Enzyme-assay guided fractionation of the extract led to the isolation of methyl caffeate (1) as a rat intestinal sucrase and maltase inhibitor. We examined 13 caffeoyl derivatives for sucrase- and maltase-inhibitory activities. The results showed that methyl caffeate (1) had a most favorable structure for both sucrase and maltase inhibition, except for a higher activity of methyl 3,4,5-trihydroxycinnamate (14) against sucrase. Its moderate inhibitory action against α-glucosidase provides a prospect for antidiabetic usage of S. torvum fruit.

  在日本南岛种子岛栽培的325种植物中，筛选大鼠肠道α-葡萄糖苷酶（蔗糖酶和麦芽糖酶）抑制剂的实验发现，茄属植物Solanum torvum果实提取物对蔗糖酶和麦芽糖酶均有显著抑制作用。通过酶活性导向的提取物分级分离，得到了作为大鼠肠道蔗糖酶和麦芽糖酶抑制剂的咖啡酸甲酯（1）。我们检测了13种咖啡酸衍生物对蔗糖酶和麦芽糖酶的抑制活性。结果显示，咖啡酸甲酯（1）在蔗糖酶和麦芽糖酶抑制方面具有最优的结构，除了对蔗糖酶活性更高的3,4,5-三羟基肉桂酸甲酯（14）外。其对α-葡萄糖苷酶的中等抑制作用为Solanum torvum果实的抗糖尿病用途提供了前景。
