The Glide scores of methyl-hispolon-estrogen receptor α (ERα) and methyl-hispolon-ERβ docked complexes were -7.29 kcal/mol and -6.68 kcal/mol in docking simulations. Methyl-hispolon had a significant antiproliferative effect for estrogen-sensitive ER(+) MCF-7 cells in the absence of estrogen, and it exhibited dual estrogen activities. Methyl-hispolon increased the serum E2 in rats with premature ovarian failure and fulfilled the estrogenic function in the uterus and ovary. Methyl-hispolon significantly inhibited the expression of Ras, API, ERα, C-myc, and cyclinDl, as well as their gene transcription in RL95-2 cells. The phosphorylation of ERK1/2 was inhibited by methyl-hispolon. Thus, methyl-hispolon has potential use in treating estrogen deficiency-related diseases, with good antitumor effects and estrogenic activity. %8 2019-04-11
