The function of Immune control, haematopoiesis, and inflammation all depend on the cytokine Interleukin 6 (IL-6), and higher expression of IL-6 is seen in COVID-19 and other diseases. The immune protein IL-6 activation is dependent on binding interactions with IL-6Rα, mIL-6R, and sIL-6R for its cellular function. Termination of these reaction could benefit for controlling the over-expression in COVID-19 patients and that may arise as inhibitors for controlling COVID-19. Traditionally, the goat milk has been prescribed as medicine in ayurvedic practice and through this work, we have explored the benefits of peptides from goat milk as IL-6 inhibitors, and it have the potential of inhibiting the over expression of IL-6 and control the COVID-19 disease. Computational experiments have shown that goat peptides had strong interactions with IL-6, with higher scoring profiles and energy efficiency ranging from -6.00 kcal/mol to -9.00 kcal/mol in docking score and -39.00 kcal/mol in binding energy. Especially the YLGYLEQLLR, VLVLDTDYK and AMKPWIQPK peptides from goat milk holds better scoring and shows strong interactions were identified as the most potential IL-6 inhibitor candidates in this study. Peptides from Goat proteins, which are capable of binding to the IL-6 receptor with strong binding conformations, have no negative effects on other immune system proteins.
免疫调控、造血和炎症功能均依赖于细胞因子白细胞介素6（IL-6），在新冠肺炎及其他疾病中可见IL-6的高表达。免疫蛋白IL-6的激活依赖于其与IL-6Rα、mIL-6R和sIL-6R的结合相互作用以实现其细胞功能。终止这些反应可能有利于控制新冠肺炎患者体内的过度表达，这可能作为控制新冠肺炎的抑制剂出现。传统上，山羊奶在阿育吠陀医学实践中被用作药物，通过这项研究，我们探索了山羊奶中的肽作为IL-6抑制剂的益处，其具有抑制IL-6过度表达和控制新冠肺炎疾病的潜力。计算实验表明，山羊肽与IL-6有强烈的相互作用，对接评分较高，能量效率在对接分数方面为-6.00千卡/摩尔至-9.00千卡/摩尔，结合能为-39.00千卡/摩尔。特别是来自山羊奶的YLGYLEQLLR、VLVLDTDYK和AMKPWIQPK肽具有更好的评分并显示出强烈的相互作用，在本研究中被确定为最有潜力的IL-6抑制剂候选物。来自山羊蛋白的肽能够以强结合构象与IL-6受体结合，对其他免疫系统蛋白没有负面影响。
