Substituted amide derivatives of C4-ageratochromene dimer analog (19) were synthesized through structural modification of precocene-I (4a), isolated from the essential oil of Ageratum conyzoides L. The target compounds (18–20, 23I-VI, 24I-VI, and 25I-VI) were evaluated for their bone-forming effect using osteoblast differentiation assay. Seven compounds (23I, 23II, 23IV, 23VI, 24III, 24VI, and 25VI)
C4-ageratochromene 二聚体类似物 ( 19 ) 的取代酰胺衍生物是通过对从Ageratum conyzoides L的精油中分离得到的precocene-I ( 4a )进行结构修饰而合成的。目标化合物(18 - 20,23I-VI,24I-VI,和25I-VI),用于使用成骨细胞分化测定其骨成形效果进行了评价。七种化合物(23I、23II、23IV、23VI、24III、24VI和25VI)在 1 pM–1 nM 浓度范围内表现出良好的活性。在 1 pM 浓度下,最活跃的化合物即23II显示成骨细胞的有效矿化以及成骨标记基因即RUNX 2,BMP-2和1型胶原蛋白(Type-1 col)的表达,对成骨细胞没有任何毒性。18和20的单晶X射线分析表明,这些分子的核心核带有反式-芪类系统中的苯环,并且与17β-雌二醇(1)和己烯雌酚(DES,3)具有良好的结构相关性。关于23II的计算机研究显示其与雌激素受体
