Abstract

Flavonoids are polyphenolic compounds with a fifteen carbon basic skeleton (C6-C3-C6) composed of two benzene rings, A and B, connected by a pyran-C heterocyclic ring. The high interest in flavonoid research appears due to the numerous benefits of this compound based on its antioxidant activity. Various authors reported multiple studies in this regard. The research on methods of extraction, identification, quantification, and testing of antioxidant activity is compiled in this review. The most important part of this study is a review of the antioxidant activity assay method, which is equipped with the reaction mechanism.

Abstract

Introdiction: Oxidative stress is a condition caused by an imbalance between the level of oxidants in cells and tissues and the ability of the biological system to detoxify these reactive products. To compensate for the excess oxidant molecules, the human body requires the intake of antioxidant compounds through diet or medicinal plants to overcome the deficiency of these endogenous antioxidants. Zerumbone is the main bioactive compound of the Zingiber zerumbet L. Smith rhizome that was reported to have antioxidant activity and different pharmacological effects, like anti-inflammatory, anti-cancer, antidiabetic, immunomodulatory, anti-neurodegenerative disease, hepatoprotective, and gastroprotective. Aims: This review aims to gather available scientific research data regarding the antioxidant activity of zerumbone and its pharmacological prospects under conditions of oxidative stress. This paper is an overview of previous research on the various pharmacological activities of zerumbone and studies of its mechanism of action related to oxidative stress at the molecular level. The selected articles are related research reports for the 2010–2022 period, which can be accessed online through NCBI, Science Direct, MDPI, and Google Scholar. Result: The research results mentioned in this review paper can summarize knowledge to explain the pharmacological potential of zerumbone so that it can be used as a starting point or comparison in designing further research. Conclusion: The results of the reviews show that the various pharmacological prospects of zerumbone are related to oxidative stress conditions through various modes of action.

Abstract

Introduction: Rutin is a flavonol glycoside that is known to have blood sugar reducing activity. However, its molecular mechanism in reducing blood sugar level remains unclear. This study was employed to elucidate the pharmacological mechanism of rutin as antidiabetic agent. Methods: Potential target of rutin was screened in relevant databases to construct a compound-target network. Network pharmacology was utilized to identify targets associated with disease, gene ontology and KEGG pathways and confirmed its potential binding affinity using Autodock 4.2 assisted by ADT interface. Result: The result highlighted mTor, PIK3R1, and NFKB1R as a potential target of Rutin through network pharmacology. This target involved in the insulin signaling pathways, insulin resistance, type 2 diabetes mellitus, B receptor signaling pathways, AGE-RAGE signaling pathway in diabetic complications and pancreatic cancer. All docking protocols were valid with RMSD value for TNF-a, NF-KB, PI3K were 0.72 Å, 0.67 Å, ​​and 0.54 Å, respectively. The molecular docking has confirmed the potential mechanism of rutin as antidiabetic agent by stably bound with these proteins with estimated free binding energy values of -8.54 kcal/mol (NF-KB), -8.01 kcal/mol (PI3K), and -6.22 kcal/mol (TNF-a). Conclusion: The study has given insight into the molecular mechanism of rutin in the management of DM by stably bound with NF-KB, TNF-a, and PI3K. However, further laboratory experimental research is needed, particularly in vitro and in vivo assay
