Superoxide dismutase as multipotent therapeutic antioxidant enzyme: Role in human diseases

Priyanka Saxena et al. Biotechnol Lett. 2022 Jan.

Abstract

Reactive oxygen species (ROS) is consistently recognized as a threat to living organisms, especially for human beings. For proper working of cellular signaling, functioning, and survival, a strict and balanced level of ROS is necessary. Superoxide dismutase (SOD); a group of metalloenzymes provides an important antioxidant defense mechanism, required to preserve the level of ROS in the body. The enzyme reveals the therapeutic potential against various diseases due to a deficiency in the ROS level. The review illustrates the numerous clinical aspects of SOD in various physiological and pathological conditions such as cancer, diabetes, arthritis, cardiovascular, neurodegenerative diseases, etc., with the mechanism of action. Despite limitations, the SOD enzyme has proved as a powerful tool against diseases, and various forms of conjugates and mimetics have been developed and reported to make it more efficient. Extensive studies need in this direction for use of natural SOD-based therapeutics for the prevention and cure of diseases.

Keywords: Metalloenzyme; Pathophysiological conditions; Reactive oxygen species; SOD-based therapeutics.
