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) presented good activity within 1 pM-1 nM concentration. At 1 pM concentration, the most active compound i.e. 23II showed effective mineralization of osteoblast cells along with expression of osteogenic marker genes viz RUNX 2, BMP-2, and type 1 collagen (Type-1 col) without any toxicity towards osteoblast cells. Single crystal X-ray analysis of 18 and 20 revealed that the core nucleus of these molecules bear phenyl rings in a Trans-stilbenoid system and had a good structural correlation with 17β-estradiol (1) and diethylstilbestrol (DES, 3). In-silico study about 23II showed its structural complementarities with the LBD of estrogen receptor (ER) which indicated possible ER-mediated activity of compounds.
