4-羥基苯乙烯的合成（微波輔助法）：在100 mL錐形瓶中加入4-羥基苯甲醛（1.0 g，8.2 mmol）、丙二酸（1.69 g，16.3 mmol）和三乙胺（2-4 mL），隨后加入乙酸（10-15 mL）。錐形瓶口覆蓋松散放置的漏斗，充分搖勻后置于微波反應(yīng)器中，分批次進(jìn)行微波輻射（2-8分鐘）。反應(yīng)完成后，將混合物冷卻至室溫，倒入冰水中，并用乙酸乙酯萃取。有機(jī)相依次用碳酸氫鈉溶液、稀鹽酸和飽和氯化鈉溶液洗滌，無水硫酸鈉干燥。減壓濃縮除去溶劑，得到粗產(chǎn)物。通過硅膠柱色譜法純化，洗脫劑為己烷/乙酸乙酯（9:1至6:4，v/v），得到具有甜香氣味的4-羥基苯乙烯，產(chǎn)率40%。產(chǎn)物結(jié)構(gòu)經(jīng)1H NMR和13C NMR確認(rèn)：1H NMR (CDCl3) δ 7.31 (2H, d, J = 8.5 Hz, H-2和H-6), 6.81 (2H, d, J = 8.8 Hz, H-3和H-5), 6.67 (1H, dd, J = 17.8 Hz, 11.3 Hz, CH=CH2), 5.51 (1H, s, OH), 5.20 (1H, d, J = 17.8 Hz, 順式-CH=CH2), 5.14 (1H, d, J = 11.3 Hz, 反式-CH=CH2); 13C NMR (CDCl3) δ 155.5 (C-1), 136.5 (CH=CH2), 130.9 (C-4), 128.0 (C-3和C-5), 115.8 (C-2和C-6), 112.0 (CH=CH2)。

常見問題列表
4-Vinylphenol (12.5-200 μg/mL) significantly reduces cell viability in parental MDA-MB-231 cells, and the IC50 value is 109 μg/mL.
4-Vinylphenol (0.15 or 0.3 μg/mL; 3 days) reduces sphere?formation and vimentin expression on CSCs in breast cancer.
4-Vinylphenol (50, 100 μg/mL; 72 hours) significantly suppresses cell proliferation in CSC-enriched MDA-MB-231 cells. 4-Vinylphenol significantly reduces ALDH1A1 expression by 50% in CSC-enriched MDA-MB-231 cells.
4-Vinylphenol (100 μg/mL) significantly increases the expressions of caspase 3, likely sensitizing CSC-enriched MDAMB-231 cells to apoptosis.
