One strategy to manage resistant pathogens and develop potential anticancer drugs is the search for new, promising, and cost-effective medicinal benefits in the field of bioactive metabolites derived from mushrooms. In the current study, Egyptian cultivated fruiting bodies polar extract was prepared to evaluate its antimicrobial activities as well as its cytotoxic effect on various cancer cell lines. The polar extract (PoPE) was characterized by its phenolic and flavonoid content. The phenolics and flavonoids of PoPE were 6.94 and 0.15 mg/g, respectively. polar extract showed potent antimicrobial activity against four pathogens, including , , and . PoPE was found to inhibit (47%), (28%) as well as (21%). PoPE was found to be 13 times more selective and toxic to MCF-7 cells than Vero normal cells, with the lowest IC50 value (4.5 μg/mL), so they were selected to examine the potential cytotoxic effects of PoPE. In MCF-7 cells, PoPE appeared to promote cell cycle arrest in the sub-G1 stage, as well as apoptosis. It significantly increased TNF-α production while decreasing IL-6 levels. PoPE's total antioxidant capacity, lipid peroxide, and glutathione reductase activity were recorded 0.14 ± 0.02 mM/L, 15.60 ± 0.015 nmol/mL, and 9.50 ± 1.30 U/L, respectively. The existence of different bioactive metabolites was investigated GC-MS, which confirmed the presence of 15 compounds with well-known biological activity.
应对耐药病原体并开发潜在抗癌药物的一种策略是,在源自蘑菇的生物活性代谢物领域寻找新的、有前景且具有成本效益的药用价值。在本研究中,制备了埃及栽培子实体的极性提取物,以评估其抗菌活性以及对各种癌细胞系的细胞毒性作用。极性提取物(PoPE)通过其酚类和黄酮类成分进行表征。PoPE的酚类和黄酮类含量分别为6.94和0.15毫克/克。极性提取物对四种病原体表现出强大的抗菌活性,包括[此处原文缺失病原体名称]、[此处原文缺失病原体名称]和[此处原文缺失病原体名称]。发现PoPE可抑制[此处原文缺失被抑制对象名称](47%)、[此处原文缺失被抑制对象名称](28%)以及[此处原文缺失被抑制对象名称](21%)。发现PoPE对MCF - 7细胞的选择性和毒性比对Vero正常细胞高13倍,IC50值最低(4.5微克/毫升),因此选择它们来研究PoPE的潜在细胞毒性作用。在MCF - 7细胞中,PoPE似乎促进细胞周期停滞在亚G1期以及诱导凋亡。它显著增加肿瘤坏死因子 - α的产生,同时降低白细胞介素 - 6水平。PoPE的总抗氧化能力、脂质过氧化物和谷胱甘肽还原酶活性分别记录为0.14±0.02毫摩尔/升、15.60±0.015纳摩尔/毫升和9.50±1.30单位/升。通过气相色谱 - 质谱联用(GC - MS)研究了不同生物活性代谢物的存在情况,证实存在15种具有已知生物活性的化合物。
