Gambogic acid: A shining natural compound to nanomedicine for cancer therapeutics

Area of Science:

• Natural Product Chemistry
• Pharmacology
• Oncology

Background:

• Current cancer therapies face challenges like high cost, systemic toxicity, drug resistance, metastasis, and recurrence.
• There is an urgent need for safe and effective natural compounds for cancer prevention and treatment.
• Gambogic acid (GA), a xanthone from Garcinia hanburyi resin, exhibits promising anti-cancer biological activities.

Purpose of the Study:

• To review the distinct biological characteristics of gambogic acid (GA) as a novel anti-cancer agent.
• To delineate the molecular mechanisms underlying GA's anti-cancer, anti-metastasis, and anti-angiogenesis effects.
• To describe the development and application of gambogic acid-based nanomedicine.

Main Methods:

• Literature review of biological characteristics and molecular mechanisms of gambogic acid.
• Analysis of studies on GA's anti-cancer, anti-metastasis, anti-angiogenesis, and chemo-/radiation sensitizer activities.
• Review of recent advancements in gambogic acid nanoformulations.

Main Results:

• Gambogic acid (GA) demonstrates a broad spectrum of biological benefits against various cancers.
• GA exhibits potent anti-cancer, anti-metastasis, and anti-angiogenesis activities through specific molecular pathways.
• GA acts as a chemo- and radiation sensitizer, enhancing the efficacy of conventional treatments.
• Development of gambogic acid nanoformulations (nanomedicine) has been described.

Conclusions:

• Gambogic acid is a promising natural compound with significant potential for cancer therapy.
• Understanding GA's molecular mechanisms supports its development as a novel anti-cancer agent.
