Abstract:
Cancer cells produce high levels of reactive oxygen species (ROS) that lead to a state of increased basal oxidative stress. Since this state of oxidative stress makes cancer cells vulnerable to agents that further augment ROS levels, the use of pro-oxidant agents is emerging as an exciting strategy to selectively target tumor cells. Natural products have provided a significant contribution to the development of several drugs currently used in cancer chemotherapy. Although many natural products are known to affect the redox state of the cell, most studies on these compounds have focused on their antioxidant activity instead of on their pro-oxidant properties. This article provides an overview of natural products with pro-oxidant and anticancer activities, with special focus on plant secondary metabolites, and discusses their possible use as cancer chemotherapeutic agents.
Insights
Cancer cells
Area of Science:
- Biochemistry
- Pharmacology
- Oncology
Background:
- Cancer cells exhibit elevated reactive oxygen species (ROS) levels, creating a state of heightened oxidative stress.
- This increased oxidative stress renders cancer cells susceptible to agents that further elevate ROS.
- Targeting tumor cells selectively using pro-oxidant agents is a promising therapeutic strategy.
Purpose of the Study:
- To provide an overview of natural products exhibiting pro-oxidant and anticancer activities.
- To highlight plant secondary metabolites as a key source of such compounds.
- To discuss the potential of these natural products as anticancer chemotherapeutic agents.
Main Methods:
- Literature review of natural products with documented pro-oxidant and anticancer effects.
- Focus on studies investigating the impact of natural products on cellular redox state.
- Analysis of plant secondary metabolites for their pro-oxidant properties.
Main Results:
- Many natural products influence cellular redox state, but their pro-oxidant effects are often overlooked.
- Plant secondary metabolites demonstrate significant pro-oxidant and anticancer activities.
- Evidence suggests these compounds can selectively target cancer cells.
Conclusions:
- Natural products, particularly plant secondary metabolites, possess pro-oxidant properties beneficial for cancer therapy.
- Further research into the pro-oxidant activities of natural products could lead to novel chemotherapeutic agents.
- Exploiting the vulnerability of cancer cells to ROS is a viable approach for developing new cancer treatments.
