The discovery of biomolecules has been the subject of extensive research for several years due to their potential to combat harmful pathogens that can lead to environmental contamination and infections in both humans and animals. This study aimed to identify the chemical profile of endophytic fungi, namely and , which were isolated from and . We identified several HPLC-MS compounds, including Ethylidene-3,39-biplumbagin, Pestauvicolactone A, Phenylalanine, 2-Isopropylmalic acid, Fusaproliferin, Sespendole, Ansellone, Calanone derivative, Terpestacin, and others. Solid-state fermentation was conducted for 14-21 days, and methanol and dichloromethane extraction were performed to obtain a crude extract. The results of our cytotoxicity assay revealed a CC value > 500 μg/mL, while the virucide, Trypanosoma, leishmania, and yeast assay demonstrated no inhibition. Nevertheless, the bacteriostatic assay showed a 98% reduction in and . Our findings suggest that these endophytic fungi species with distinct chemical profiles represent a promising niche for further exploring new biomolecules.
由于生物分子具有对抗有害病原体的潜力,而这些病原体可导致环境污染以及人类和动物感染,因此生物分子的发现多年来一直是广泛研究的主题。本研究旨在鉴定从[具体来源1]和[具体来源2]分离出的内生真菌[真菌名称1]和[真菌名称2]的化学特征。我们鉴定了几种高效液相色谱-质谱化合物,包括亚乙基-3,3'-联双柏拉醇、佩斯托维内酯A、苯丙氨酸、2-异丙基苹果酸、镰孢增殖菌素、悬垂内酯、安塞尔酮、卡拉酮衍生物、萜霉素等。进行了14至21天的固态发酵,并进行甲醇和二氯甲烷萃取以获得粗提物。我们的细胞毒性试验结果显示细胞毒性浓度值>500μg/mL,而杀病毒、锥虫、利什曼原虫和酵母菌试验均未显示出抑制作用。然而,抑菌试验显示[具体细菌1]和[具体细菌2]减少了98%。我们的研究结果表明,这些具有独特化学特征的内生真菌物种是进一步探索新生物分子的一个有前景的领域。
