Abstract

Background: The clinical effectiveness of wide range of currently available anticancer drugs is being reduced .HIF-1 alpha is essential for the reprogramming of cancer cells' metabolism,so cancer treatments include inhibiting the HIF-1α signaling pathway and The evidence underscores the potential of natural flavonoids as HIF-1α inhibitors in cancer therapy.

Objective: To provide  more comprehensive overview of  inhibition of flavonoids on HIF-1 which may be useful for developing new compounds with enhanced anticancer properties and also to provide reasearchers with a thought to design potent and low toxic anticancer candidates.

Material and methods: A comprehensive review of recent literature was conducted to identify studies investigating the effects of natural flavonoids and their derivatives on HIF-1α activity. Emphasis was placed on mechanisms of action, efficacy, and toxicity profiles, as well as their impact on tumor hypoxia and associated pathways such as vascularization and glycolysis.

Result: Recent findings demonstrate that various natural flavonoids effectively downregulate HIF-1α through distinct mechanisms. These compounds exhibit significant anti-cancer properties while maintaining low toxicity, making them viable candidates for further development. Several studies have also highlighted the ability of flavonoids to influence tumor vascularization and glycolytic pathways, thereby enhancing their therapeutic potential.

Conclusion: In this review in order to increase bioavailability , solubility and to better understand the impact of anticancer flavonoids on HIF-1 alpha, amino acids or amino groups were added to the flavonoid structure. understanding the effect of anticancer flavonoids on HIF-1 α may be relevant in the development of novel compounds with increased anticancer activity.
