Abstract Recently, as a drug target in cancer treatment, the superfamily of glutathione S‐transferase (GSTs, EC 2.5.1.18) have been invited considerable interest by scientists. In particular, they are overexpressed many human cell lines, GSTs can catalyze conjugation cellular nucleophile (GSH) with wide range electrophilic carcinogens toxins and drugs, meanwhile producing oxidative stress. For this purpose, GST was purified GSH‐agarose affinity chromatography, some calcium channel blockers (CCBs), such amlodipine, cinnarizine, isradipine, nifedipine, nilvadipine, were assessed for their inhibitory actions against GST. The CCBs demonstrated micromolar levels activity towards ( K I s spanning within 98.84±0.53 μM–502.70±2.53 μM range). best observed isradipine. Additionally, molecular docking study performed competitive inhibitor nilvadipine on to describe possible interaction active site confirm activity.

Redox equilibria and the modulation of redox signalling play crucial roles in physiological processes. Overproduction reactive oxygen species (ROS) disrupts body's antioxidant defence, compromising homeostasis increasing oxidative stress, leading to development several diseases. Manganese superoxide dismutase (MnSOD) is a principal enzyme that protects cells from damage by converting anion radicals hydrogen peroxide mitochondria. Systematic studies have demonstrated MnSOD plays an indispensable role multiple This review focuses on preclinical evidence describes mechanisms diseases accompanied with imbalanced status, including fibrotic diseases, inflammation, diabetes, vascular neurodegenerative cancer.
