Molecular targets of celastrol in cancer: Recent trends and advancements

Area of Science:

• Phytochemistry
• Molecular Biology
• Cancer Research

Background:

• Cancer remains a leading global cause of death despite advances in medical facilities.
• Phytochemicals, particularly terpenoids like celastrol, are gaining attention for their potential anti-cancer properties.
• Celastrol, a pentacyclic terpenoid, exhibits diverse pharmacological activities relevant to cancer treatment.

Purpose of the Study:

• To review the molecular mechanisms underlying celastrol's anti-cancer effects.
• To elucidate how celastrol influences cancer initiation and progression.
• To inform the development of novel therapeutic strategies using celastrol.

Main Methods:

• Literature review of studies on celastrol's pharmacological properties.
• Analysis of celastrol's impact on various cancer signaling pathways.
• Examination of celastrol's effects on apoptosis, angiogenesis, metastasis, and inflammation.

Main Results:

• Celastrol demonstrates anti-proliferative activity through multiple molecular pathways.
• Its anti-cancer effects are linked to pro-apoptotic (Protein Kinase B), anti-angiogenic (VEGF, VEGFR), anti-metastatic (MMPs), and anti-inflammatory (cytokines, chemokines) actions.
• Celastrol modulates key signaling pathways involved in cancer biology.

Conclusions:

• Celastrol possesses significant potential as an anti-cancer agent.
• Understanding its molecular mechanisms is crucial for developing effective cancer therapies.
• Celastrol's multifaceted actions offer a promising avenue for novel cancer treatment strategies.
