The protective effect of some Thai plants and their bioactive compounds in UV light-induced skin carcinogenesis

Area of Science:

• Dermatology and Oncology
• Photobiology
• Natural Product Chemistry

Background:

• Skin cancer, particularly melanoma, poses a significant public health threat, with solar UVB radiation as a primary carcinogen.
• UVB-induced reactive oxygen species (ROS) drive inflammation and immune changes, contributing to skin cancer development.
• Current melanoma therapies face challenges with drug resistance, increasing interest in novel chemopreventive agents.

Purpose of the Study:

• To explore the potential of Thai plants and their bioactive compounds as chemopreventive agents against UV-induced skin cancer.
• To evaluate the antioxidant, antimutagenic, and anticarcinogenic properties of plant-derived compounds.
• To assess the efficacy of these natural compounds in experimental models of skin carcinogenesis.

Main Methods:

• Review of existing literature on Thai flora and their medicinal properties.
• Analysis of the mechanisms by which bioactive compounds exert chemopreventive effects (e.g., antioxidant, anti-inflammatory).
• Examination of experimental data from in vitro and in vivo models of UV-induced skin cancer.

Main Results:

• Thai plants possess bioactive compounds with demonstrated antioxidant, antimutagenic, and anticarcinogenic properties.
• These compounds have shown protective effects against UV light-induced skin damage and cancer in various experimental models.
• The identified compounds exhibit potential for targeted or adjuvant therapy in melanoma treatment.

Conclusions:

• Thai plants and their bioactive compounds represent a promising source for novel chemopreventive strategies against skin cancer.
• Further in vivo research and clinical studies are warranted to establish efficacy and safety for therapeutic use.
• Natural compounds offer a potential avenue to overcome drug resistance in current melanoma therapies and enhance photocarcinogenesis prevention.
