摘要

众所周知,海洋硅藻Chaetoceros gracilis是调节水产养殖物种营养成分的关键角色。它能合成一系列高价值的生物活性化合物,如氨基酸、脂类、萜类和多糖,因此也是一种潜在的治疗和营养保健品。这项基于硅学的研究通过综合网络药理学和分子对接方法,阐明了硅藻 C. gracilis 不同化合物、蛋白质和通路之间的交互关联。根据对检测到的 41 种化合物的网络分析,饱和碳氢化合物、二萜类化合物和酚类化合物的得分最高(140 分)。这些化合物被进一步编码为约 349 个蛋白质靶标和近 490 个不同的通路。根据 STRING 数据库,HSP90AA1、STAT3、HIF1A、MTOR、ESR1、PIK3CA、MAPK1 和 PTGS2 的蛋白质相互作用程度最高。基因富集分析进一步显示,这些蛋白质与癌症途径、神经活性配体-受体相互作用、钙和 cAMP 信号途径、PI3K-Akt 信号途径、阿尔茨海默病和神经退行性病变途径等代谢途径密切相关,而这些途径在乳腺癌、前列腺癌、肝癌、精神分裂症及其他精神和高血压疾病的代谢过程中发挥着重要作用。此外,研究人员还对一些新型化合物与 mTOR 和 HSP90AA1 进行了分子对接和毒性评估,结果表明它们之间的相互作用前景广阔且稳定。因此,本研究首次从硅学角度概述了从海洋硅藻C.gracilis中提取的新型生物活性化合物的抗癌和神经保护潜力。

Characterization of natural compounds derived from diatom C. gracilis as potential therapeutic agents: An in-silico networking and docking study

Marine diatom Chaetoceros gracilis have been known as the key player regulating the nutritional content of aquaculture species. Being able to synthesize an array of high value bioactive compounds like amino acids, lipids, terpenoids and polysaccharides, it also serves as potential therapeutic and nutraceutical agent. This in silico-based study elucidates the interactive association of different compounds, proteins and pathways of the diatom C. gracilis through an integrated network pharmacology and molecular docking approach. According to the Network analysis of the 41 compounds detected, saturated hydrocarbons, diterpenoids and phenolic compounds scored the highest degree (score > 140). These compounds were further coded for approximately 349 protein targets and almost 490 different pathways. HSP90AA1, STAT3, HIF1A, MTOR, ESR1, PIK3CA, MAPK1 and PTGS2 secured highest degree of protein-protein interaction according to STRING database. The gene enrichment analysis further revealed that these proteins were closely associated with metabolic pathways like Pathways in cancer, neuroactive ligand-receptor interaction, calcium and cAMP signaling pathway, PI3K-Akt signaling pathway, Alzheimer's disease and pathways of neurodegeneration which played an instrumental role in the metabolism of diseases and disorders like cancers of breast, prostrate, and liver, schizophrenia and other mental and hypertensive disorders. Furthermore, the molecular docking and toxicity assessment of a few novel compounds was done with mTOR and HSP90AA1 which revealed promising and stable interactions. Thus, this study provides the first in silico insight outlining the anti-cancerous and neuroprotective potential of novel bioactive compounds derived from marine diatom C.gracilis.

期刊介绍: Algal Research is an international phycology journal covering all areas of emerging technologies in algae biology, biomass production, cultivation, harvesting, extraction, bioproducts, biorefinery, engineering, and econometrics. Algae is defined to include cyanobacteria, microalgae, and protists and symbionts of interest in biotechnology. The journal publishes original research and reviews for the following scope: algal biology, including but not exclusive to: phylogeny, biodiversity, molecular traits, metabolic regulation, and genetic engineering, algal cultivation, e.g. phototrophic systems, heterotrophic systems, and mixotrophic systems, algal harvesting and extraction systems, biotechnology to convert algal biomass and components into biofuels and bioproducts, e.g., nutraceuticals, pharmaceuticals, animal feed, plastics, etc. algal products and their economic assessment
