Stress during pregnancy significantly impacts offspring early physiological programming. Herbal remedies are frequently used by pregnant women to enhance their wellbeing. Leaf Extract (MoLE) is believed to have both anti-stress and antioxidant properties which can act as a Selective Estrogen Receptor Modulator (SERM) that regulate activities of estrogen, and can have different effects on different tissues. Goal of this study is to compile information on molecular docking analysis of phytochemicals found in MoLE targeting Estrogen Receptor-alpha (ER-α) and assess effects of MoLE administration on dam's and fetal brain tissues and placenta, during gestational stress.
Phytochemical study of MoLE was determined using Gas Chromatography-Mass Spectrometry. Molecular docking technique was employed to predict aspects of interaction and binding affinities energy of bioactive phytocompounds in protein site of ER-α using autodock tools. 30 apparently healthy pregnant Albino-Wistar rats were randomly placed into 6 groups of 5 rats per group and exposed to Chronic Unpredictable Stress (CUS) protocol for two weeks, as follows: Group I (water and normal rat chow ), Group II (CUS protocol only), Group III (5 body weight/day of MoLE), Group IV (10 body weight/day of MoLE), Group V (CUS protocol +5 body weight/day of MoLE), Group VI (CUS protocol +10 body weight/day of MoLE).
This study found that 1-Propanol, 3,3'-oxy bis- and 1, 2, 3-Trimethyldiaziridine are most potent ligands for ER-α among all 41 compounds. Photomicrograph examination of tissues from stressed rats showed mild to severe alterations in histology. Consumption of MoLE during chronic stress showed mild to moderate protective effects.
These findings suggest that 1-Propanol, 3,3'-oxy bis- and 1, 2, 3-Trimethyldiaziridine can be further investigated for development of novel therapeutics.
孕期应激会显著影响子代早期的生理编程。孕妇经常使用草药疗法来增进自身健康。桑叶提取物(MoLE)被认为具有抗应激和抗氧化特性,可作为选择性雌激素受体调节剂(SERM)调节雌激素活性,且对不同组织可能产生不同影响。本研究的目的是汇总关于MoLE中发现的植物化学物质针对雌激素受体α(ER-α)的分子对接分析信息,并评估在孕期应激期间给予MoLE对母鼠和胎儿脑组织及胎盘的影响。
采用气相色谱 - 质谱法对MoLE进行植物化学研究。利用自动对接工具,采用分子对接技术预测生物活性植物化合物在ER-α蛋白位点的相互作用和结合亲和力能量等方面。将30只表面健康的妊娠白化Wistar大鼠随机分为6组,每组5只,按照慢性不可预测应激(CUS)方案处理两周,分组如下:第一组(给予水和正常大鼠饲料),第二组(仅采用CUS方案),第三组(每天给予5毫克/千克体重的MoLE),第四组(每天给予10毫克/千克体重的MoLE),第五组(CUS方案 + 每天5毫克/千克体重的MoLE),第六组(CUS方案 + 每天10毫克/千克体重的MoLE)。
本研究发现,在所有41种化合物中,1 - 丙醇、3,3'-氧双 - 和1,2,3 - 三甲基二氮杂环丙烷是ER-α最有效的配体。对应激大鼠组织的显微照片检查显示组织学有轻度至重度改变。在慢性应激期间食用MoLE显示出轻度至中度的保护作用。
这些发现表明,1 - 丙醇、3,3'-氧双 - 和1,2,3 - 三甲基二氮杂环丙烷可进一步研究用于开发新型治疗药物。
