(+/-)-5-Hydroxy-1,7-bis-(4'-hydroxyphenyl)-3-heptanone (2a), (+/-)-5-hydroxyl-1-(4'-hydroxyphenyl)-7-phenyl-3-heptanone (2b), (+/-)-5-hydroxy-7-(4'-hydroxyphenyl)-1-phenyl-3-heptanone (2c), and (+/-)-5-hydroxy-1,7-bis-(phenyl)-3-heptanone (2d) have been synthesized to study the structure-activity relationship regarding digestibility inhibition in vitro in cow rumen fluid. The activities were compared with the activity of chiral (S)-2a and its glucoside platyphylloside (1), isolated from Betula pendula. Compound 2a was slightly less active, 2b and 2c were more active, and 2d was less active than (S)-2a and platyphylloside.
(±)-5-羟基-1,7-双-(4'-羟基苯基)-3-庚酮 (2a)、(±)-5-羟基-1-(4'-羟基苯基)-7-苯基-3-庚酮 (2b)、(±)-5-羟基-7-(4'-羟基苯基)-1-苯基-3-庚酮 (2c) 和 (±)-5-羟基-1,7-双-(苯基)-3-庚酮 (2d) 已经被合成,用于研究在牛瘤胃液中体外消化抑制的结构-活性关系。这些化合物的活性与从 Betula pendula 分离出的具有手性 (S)-2a 及其苷 platyphylloside (1) 进行了比较。化合物 2a 的活性略低于 (S)-2a 和 platyphylloside,而 2b 和 2c 的活性更高,2d 的活性则低于 (S)-2a 和 platyphylloside。
