Cytotoxic and EGFR tyrosine kinase inhibitory activities of aglycone derivatives obtained by enzymatic hydrolysis of oleoside-type secoiridoid glucosides, oleuropein and ligustroside
Hydrolysis of oleoside-type secoiridoidglucosides, oleuropein (1) and ligustroside (2), in the presence of β-glucosidase provided their aglycones, named (5S,8R,9S)-7-3,4-dihydroxyphenethyl elenolate (3) and (5S,8R,9S)-7-4-hydroxyphenethyl elenolate (4), respectively. The structures of 3 and 4 were identified by spectroscopic means and optical rotation measurements. Evaluation of the cytotoxic and
在β-葡萄糖苷酶存在的情况下,油苷型secoiridoid 葡萄糖苷、橄榄苦苷( 1 ) 和川芎苷( 2 ) 的水解提供了它们的苷元,命名为(5 S ,8 R ,9 S )-7-3,4-dihydroxyphenethylelenolate ( 3 ) 和 (5 S ,8 R ,9 S )-7-4-羟基苯乙酯 ( 4 ) 分别。3和4的结构通过光谱手段和旋光度测量确定。细胞毒性和表皮生长因子受体的评价(EGFR)酪氨酸激酶的化合物的抑制活性1 - 4表明化合物3和4在体外对 39 种人类癌细胞系的疾病导向组表现出中等的细胞毒性,而化合物3抑制了该酶。
