Abstract
BACKGROUND: Stress during pregnancy significantly impacts offspring early physiological programming. Herbal remedies are frequently used by pregnant women to enhance their wellbeing. Moringa oleifera 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. METHODS: 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 ad libitum), Group II (CUS protocol only), Group III (5 mg/kg body weight/day of MoLE), Group IV (10 mg/kg body weight/day of MoLE), Group V (CUS protocol +5 mg/kg body weight/day of MoLE), Group VI (CUS protocol +10 mg/kg body weight/day of MoLE). RESULTS: 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. CONCLUSION: These findings suggest that 1-Propanol, 3,3'-oxy bis- and 1, 2, 3-Trimethyldiaziridine can be further investigated for development of novel therapeutics.
