Abstract：
Mangifera indica L., also known as mango, is a tropical fruit that belongs to the Anacardiaceae family and is prized for its juiciness, unique flavour, and worldwide popularity. The current study aimed to probe into antidepressant power (ADP) of MIS in animals and confirmation of ADP with in silico induced-fit molecular docking. The depression model was prepared by exposing mice to various stressors from 9:00 am to 2:00 pm during 42 days study period. MIS extract and fluoxetine were given daily for 30 min before exposing animals to stressors. ADP was evaluated by various behavioural tests and biochemical analysis. Results showed increased physical activity in mice under behavioural tests, plasma nitrite and malondialdehyde (MDA) levels and monoamine oxidase A (MAO-A) activity decreased dose-dependently in MIS treated mice and superoxide dismutases (SOD) levels increased in treated groups as compared to disease control. With the peculiar behaviour and significant interactions of the functional residues of target proteins with selected ligands along with the best absorption, distribution, metabolism, excretion, and toxicity (ADMET) properties, it is concluded that catechin could be the best MAO-A inhibitor at a binding energy of -8.85 kcal/mol, and two hydrogen bonds were generated with Cys406 (A) and Gly443 (A) residues of the active binding site of MAO-A enzyme. While catechin at -6.86 kcal/mol generated three hydrogen bonds with Ala263 (A) and Gly434 (A) residues of the active site of monoamine oxidase B (MAO-B) enzyme and stabilized the best conformation. Therefore, it is highly recommended to test the selected lead-like compound catechin in the laboratory with biological system analysis to confirm its activity as MAO-A and MAO-B inhibitors so it can be declared as one of the novel therapeutic options with anti-depressant activity. Our findings concluded that M. indica seeds could be a significant and alternative anti-depressant therapy.
摘要：
印度芒果，也被称为芒果，是一种热带水果，属于Anacardiaceae家族，因其多汁而备受赞誉，独特的味道，和全球知名度。本研究旨在探讨动物MIS的抗抑郁力（ADP），并通过计算机诱导的分子对接确认ADP。通过在42天的研究期间从上午9:00至下午2:00将小鼠暴露于各种应激源来制备抑郁模型。在将动物暴露于应激源之前，每天给予MIS提取物和氟西汀30分钟。通过各种行为测试和生化分析评估ADP。结果显示，在行为测试下，小鼠的身体活动增加，与疾病对照相比，在MIS治疗的小鼠中，血浆亚硝酸盐和丙二醛（MDA）水平和单胺氧化酶A（MAO-A）活性呈剂量依赖性降低，而超氧化物歧化酶（SOD）水平在治疗组增加。由于靶蛋白的功能残基与所选配体的特殊行为和显着相互作用以及最佳吸收，分布，新陈代谢，排泄,和毒性(ADMET)特性，结论儿茶素在-8.85kcal/mol的结合能下可能是最佳的MAO-A抑制剂，MAO-A酶活性结合位点的Cys406(A)和Gly443(A)残基产生两个氢键。儿茶素在-6.86kcal/mol时与单胺氧化酶B（MAO-B）酶活性位点的Ala263（A）和Gly434（A）残基产生三个氢键，并稳定了最佳构象。因此,强烈建议在实验室中通过生物系统分析测试选定的类铅化合物儿茶素，以确认其作为MAO-A和MAO-B抑制剂的活性，因此可以将其宣布为具有抗抑郁活性的新型治疗选择之一。我们的研究结果得出结论，m草种子可能是一种重要的替代抗抑郁药。
