Fodipir, the active metabolite of mangafodipir, plays a crucial role in the mechanism of mangafodipir-mediated cytoprotection, specifically mitigating cell death induced by 7β-hydroxycholesterol.

Fodipir (Dp-dp; Dipyridoxyl diphosphate; 100 μM) demonstrates significant cytoprotective effects, effectively mitigating 7β-hydroxycholesterol (7β-OH)-induced cell death after 8 hours of treatment. It not only reduces cellular reactive oxygen species (ROS) production triggered by 7β-OH but also inhibits lysosomal membrane permeabilization (LMP), enhancing cell survival. Fodipir, as a principal metabolite of mangafodipir, plays a crucial role in the cytoprotection conferred by mangafodipir against 7β-OH-induced cytotoxicity.
