4-Vinylphenol 存在于藥用草白花蛇舌草，野生稻中，也是葡萄酒中乳酸菌對對香豆酸和阿魏酸的代謝產(chǎn)物。4-Vinylphenol 誘導凋亡 (apoptosis)，在體內(nèi)抑制血管形成并抑制浸潤性乳腺腫瘤生長。體外研究
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.
