使用植物性膳食补充剂来缓解潮热、经前综合症和生育等情况,在世界范围内是多产的。雌激素和孕激素受体(ER和PR)及其相应的类固醇激素对于缓解潮热、治疗子宫内膜异位症患者至关重要,这些途径可以影响子宫内膜癌、卵巢癌和乳腺癌的发展。然而,很少有研究调查或确定草药补充剂中作用于PR的天然产品成分。在本研究中,通过石川细胞孕酮反应元件(Pre)-荧光素酶(Luc)报告实验的生物测定指导分离,从山茱萸的树枝中分离到一个新的环烯醚萜-去甲氧基角花苷(1)和六个已知的环烯环烯醇苷(2-7)。在Pre/LUC实验中,四种植物孕激素(1、2、6、7)增强了孕酮的作用。这项研究表明,在孕酮存在的情况下,药用植物成分可能会增强孕酮信号,这可能会改变激素反应组织(如子宫和乳腺)中的孕激素受体作用。
The use of botanical dietary supplements for the alleviation of conditions such as hot flashes, premenstrual syndrome, and fertility, is prolific worldwide. Estrogen and progesterone receptors (ER and PR) and their corresponding steroid hormones are critical for the relief of hot flashes, the treatment of patients who develop endometriosis, and these pathways can influence the development of endometrial, ovarian and breast cancers. However, few studies have investigated or identified the natural product components in herbal supplements that act on the PR. In the current study, a new secoiridoid, demethoxy-cornuside (1), along with six known secoiridoids (2–7) were isolated from the twigs of dogwood (Cornus officinalis) by bioassay-guided isolation with a progesterone response element (PRE)-luciferase (Luc) reporter assay in Ishikawa cells. Four phytoprogestins (1, 2, 6, 7) potentiated the effect of progesterone in the PRE/Luc assay. This study demonstrates that C. officinalis components might potentiate progesterone signaling in the presence of progesterone, which could modify progesterone receptor action in hormone responsive tissues such as the uterus and mammary gland.
