Effects of natural products on angiogenesis in melanoma

Area of Science:

• Oncology
• Pharmacology
• Natural Product Chemistry

Background:

• Melanoma, the most aggressive skin cancer, arises from melanocyte genetic mutations, primarily caused by UV radiation exposure.
• Conventional chemotherapy for melanoma demonstrates limited efficacy, driving interest in natural product-based therapies.
• Melanoma angiogenesis, crucial for tumor growth and metastasis, is a significant therapeutic target.

Purpose of the Study:

• To review and synthesize existing literature on the inhibition of melanoma angiogenesis by natural products.
• To identify potential mechanisms through which natural products affect melanoma angiogenesis.
• To explore the therapeutic potential of natural products in preclinical and clinical settings for melanoma.

Main Methods:

• Comprehensive literature search across major scientific databases (PubMed, EMBASE, Web of Science, Ovid, ScienceDirect, CNKI).
• Systematic review and analysis of studies investigating natural products and their effects on melanoma angiogenesis.
• Identification and categorization of natural products based on their chemical structures (alkaloids, polyphenols, terpenoids, flavonoids, steroids).

Main Results:

• Twenty-seven distinct natural products were identified as effective inhibitors of melanoma angiogenesis.
• Fifteen crude extracts show promise, though their active components require further investigation.
• Natural products target key pathways including oxidative stress, immune-inflammatory responses, cell proliferation, and capillary formation.

Conclusions:

• Natural products offer a viable strategy for inhibiting melanoma angiogenesis through diverse mechanisms.
• Identified natural products and their targets (e.g., VE-cadherin, COX-2, VEGF) provide a foundation for drug development.
• Further research into these natural products can accelerate the development of novel melanoma therapeutics.
