the chemopreventive potential of algal phenols, two phloroglucinol derivatives, belonging to the class of fucophlorethols, and the known fucotriphlorethol A were obtained from the ethanolic extract of the brown alga Fucus vesiculosus L. The compounds trifucodiphlorethol A and trifucotriphlorethol A are composed of six and seven units of phloroglucinol, respectively. The compounds were examined for their
在一个关注藻酚化学预防潜力的项目中,从褐藻 Fucus vesiculosus L 的乙醇提取物中获得了属于岩藻酚类的两种间苯三酚衍生物和已知的岩藻三酚 A。 化合物 trifucodiphlorethol A 和 trifucoretrith are分别由六个和七个单位的间苯三酚组成。与单体间苯三酚相比,检查了这些化合物的癌症化学预防潜力。Trifucodiphlorethol A、trifucotriphlorethol A 以及 fucotriphlorethol A 被确定为强自由基清除剂,IC(50) 值用于清除 1,1-diphenyl-2 picrylhydrazyl 自由基 (DPPH),范围为 10.0-14.4 microg/ml。在氧自由基吸收能力 (ORAC) 测定中,所有三种化合物均能有效清除过氧自由基。此外,这些化合物显示出抑制细胞色素 P450 1A 活性,IC(50)
