Gallic acid for cancer therapy: Molecular mechanisms and boosting efficacy by nanoscopical delivery

Area of Science:

• Oncology
• Pharmacology
• Natural Products Chemistry

Background:

• Cancer is a leading global cause of death, with therapy resistance a major challenge.
• Phytochemicals, like gallic acid (GA), are explored for novel anti-cancer therapeutics due to their diverse molecular targets.
• Poor bioavailability of plant-derived compounds like GA limits their anti-tumor efficacy.

Purpose of the Study:

• To review recent research on the anti-tumor activities of gallic acid (GA).
• To elucidate the molecular mechanisms and cellular pathways targeted by GA in various cancers.
• To explore strategies for enhancing GA's bioavailability and anti-cancer potential.

Main Methods:

• Literature review of studies investigating gallic acid's anti-cancer effects.
• Analysis of research on molecular pathways (e.g., PI3K/Akt) modulated by GA.
• Examination of studies on nano-vehicle delivery systems for GA.

Main Results:

• Gallic acid demonstrates anti-tumor activity across various cancer types.
• GA effectively down-regulates pro-cancerous molecular pathways, including PI3K/Akt.
• Co-administration of GA with chemotherapy enhances cancer suppression.
• Nano-vehicle formulations improve GA's bioavailability and tumor-targeting capabilities.

Conclusions:

• Gallic acid exhibits significant potential as an anti-cancer agent, particularly against chemoresistant cancers.
• Targeting molecular pathways like PI3K/Akt is a key mechanism of GA's anti-tumor action.
• Nanotechnology offers a promising approach to overcome GA's bioavailability limitations and enhance its therapeutic efficacy.
