Abstract：
In humans, a wide range of health disorders have been induced due to an imbalanced metabolism and an excess generation of reactive oxygen species (ROS). Different biological properties found in mushrooms seem to be the reason for their customary use as a favourite delicacy. Therefore, exploration of wild edible mushrooms as a source of various biological compounds is gaining much importance today. Amanita konajensis, one of the underutilized macrofungi popularly consumed in Eastern India, demands a systematic study of its medicinal values. The study aims to explore the myco-chemical contents of A. konajensis ethanolic extract (EtAK1) and screen their antioxidant potency through various in vitro assays. GC-MS analysis identified the chemical components of EtAK1. Further, structure-based virtual screening of the identified compounds was analysed for drug-like properties and molecular docking with the human p38 MAPK protein, a potent targeting pathway for human lung cancer. The morpho-molecular features proved the authenticity of the collected mushroom. The screening assays showed that EtAK1 was abundant in flavonoids, followed by phenolics, β-carotene, and lycopene, and had strong antioxidant activity with EC50 values of 640-710 μg/mL. The GC-MS analyses of EtAK1 identified the occurrence of 19 bioactive compounds in the mushroom. In silico analysis revealed that anthraergostatetraenol p-chlorobenzoate, one of the compounds identified, displayed high binding affinity (ΔG = -10.6 kcal/mol) with human p38 MAPK. The outcome of this study will pave the way for the invention of myco-medicine using A. konajensis, which may lead to a novel drug for human lung cancer.
摘要：
在人类中,由于代谢失衡和活性氧（ROS）的过量产生，已经引起了广泛的健康障碍。蘑菇中发现的不同生物学特性似乎是它们通常用作最喜欢的美味佳肴的原因。因此,今天，野生食用蘑菇作为各种生物化合物的来源的探索越来越重要。天牛，印度东部普遍消费的未充分利用的大型真菌之一，需要对其药用价值进行系统的研究。本研究旨在通过各种体外试验，探索A.konajensis乙醇提取物（EtAK1）的真菌化学含量，并筛选其抗氧化能力。GC-MS分析鉴定了EtAK1的化学组分。Further,基于结构的虚拟筛选鉴定的化合物进行了类似药物的性质和分子对接与人p38MAPK蛋白，人类肺癌的有效靶向途径。形态分子特征证明了收集的蘑菇的真实性。筛选试验表明EtAK1富含类黄酮,其次是酚类物质，β-胡萝卜素,还有番茄红素,具有较强的抗氧化活性，EC50值为640-710μg/mL。EtAK1的GC-MS分析确定蘑菇中存在19种生物活性化合物。硅分析显示，炭疽对氯苯甲酸酯，确定的化合物之一，显示与人p38MAPK的高结合亲和力(ΔG=-10.6kcal/mol)。这项研究的结果将为使用A.konajensis的myco药物的发明铺平道路，这可能导致一种治疗人类肺癌的新药。
