Abstract

Candidiasis, caused by opportunistic fungal pathogens of the genus, poses a significant threat to immunocompromised individuals. Natural compounds derived from medicinal plants have gained attention as potential sources of anti-fungal agents. Ajwa dates ( L.) have been recognized for their diverse phytochemical composition and therapeutic potential. In this study, we employed a multi-faceted approach to explore the anti-candidiasis potential of Ajwa dates' phytochemicals. Utilizing network pharmacology, we constructed an interaction network to elucidate the intricate relationships between Ajwa dates phytoconstituents and the -associated molecular targets of humans. Our analysis revealed key nodes in the network (STAT3, IL-2, PTPRC, STAT1, CASP1, ALB, TP53, TLR4, TNF and PPARG), suggesting the potential modulation of several crucial processes (the regulation of the response to a cytokine stimulus, regulation of the inflammatory response, positive regulation of cytokine production, cellular response to external stimulus, etc.) and fungal pathways (Th17 cell differentiation, the Toll-like receptor signaling pathway, the C-type lectin receptor signaling pathway and necroptosis). To validate these findings, molecular docking studies were conducted, revealing the binding affinities of the phytochemicals towards selected protein targets of humans (ALB-rutin (-9.7 kJ/mol), STAT1-rutin (-9.2 kJ/mol), STAT3-isoquercetin (-8.7 kJ/mol), IL2-β-carotene (-8.5 kJ/mol), CASP1-β-carotene (-8.2 kJ/mol), TP53-isoquercetin (-8.8 kJ/mol), PPARG-luteolin (-8.3 kJ/mol), TNF-βcarotene (-7.7 kJ/mol), TLR4-rutin (-7.4 kJ/mol) and PTPRC-rutin (-7.0 kJ/mol)). Furthermore, molecular dynamics simulations of rutin-ALB and rutin-STAT1 complex were performed to gain insights into the stability and dynamics of the identified ligand-target complexes over time. Overall, the results not only contribute to the understanding of the molecular interactions underlying the anti-fungal potential of specific phytochemicals of Ajwa dates in humans but also provide a rational basis for the development of novel therapeutic strategies against candidiasis in humans. This study underscores the significance of network pharmacology, molecular docking and dynamics simulations in accelerating the discovery of natural products as effective anti-fungal agents. However, further experimental validation of the identified compounds is warranted to translate these findings into practical therapeutic applications.

摘要

念珠菌病由该属的机会性真菌病原体引起,对免疫功能低下的个体构成重大威胁。源自药用植物的天然化合物作为抗真菌剂的潜在来源受到了关注。阿久哇枣(Phoenix dactylifera L.)因其多样的植物化学成分和治疗潜力而受到认可。在本研究中,我们采用了多方面的方法来探索阿久哇枣植物化学成分的抗念珠菌病潜力。利用网络药理学,我们构建了一个相互作用网络,以阐明阿久哇枣植物成分与人类念珠菌病相关分子靶点之间的复杂关系。我们的分析揭示了网络中的关键节点(信号转导和转录激活因子3、白细胞介素 - 2、蛋白酪氨酸磷酸酶受体C、信号转导和转录激活因子1、半胱天冬酶1、白蛋白、肿瘤蛋白p53、Toll样受体4、肿瘤坏死因子和过氧化物酶体增殖物激活受体γ),表明可能对几个关键过程(细胞因子刺激反应的调节、炎症反应的调节、细胞因子产生的正调节、细胞对外部刺激的反应等)和真菌途径(辅助性T细胞17分化、Toll样受体信号通路、C型凝集素受体信号通路和坏死性凋亡)进行调节。为了验证这些发现,进行了分子对接研究,揭示了植物化学成分对人类选定蛋白质靶点的结合亲和力(白蛋白 - 芦丁(-9.7千焦/摩尔)、信号转导和转录激活因子1 - 芦丁(-9.2千焦/摩尔)、信号转导和转录激活因子3 - 异槲皮苷(-8.7千焦/摩尔)、白细胞介素2 - β - 胡萝卜素(-8.5千焦/摩尔)、半胱天冬酶1 - β - 胡萝卜素(-8.2千焦/摩尔)、肿瘤蛋白p53 - 异槲皮苷(-8.8千焦/摩尔)、过氧化物酶体增殖物激活受体γ - 木犀草素(-8.3千焦/摩尔)、肿瘤坏死因子 - β - 胡萝卜素(-7.7千焦/摩尔)、Toll样受体4 - 芦丁(-7.4千焦/摩尔)和蛋白酪氨酸磷酸酶受体C - 芦丁(-7.0千焦/摩尔))。此外,对芦丁 - 白蛋白和芦丁 - 信号转导和转录激活因子1复合物进行了分子动力学模拟,以深入了解所鉴定的配体 - 靶点复合物随时间的稳定性和动力学。总体而言,这些结果不仅有助于理解阿久哇枣特定植物化学成分在人类中抗真菌潜力的分子相互作用,还为开发针对人类念珠菌病的新型治疗策略提供了合理依据。本研究强调了网络药理学、分子对接和动力学模拟在加速发现天然产物作为有效抗真菌剂方面的重要性。然而,需要对所鉴定的化合物进行进一步的实验验证,以便将这些发现转化为实际的治疗应用。
