Reactive oxygen species (ROS) are double-edged swords in biological systems-they are essential for normal cellular functions but can cause damage when accumulated due to oxidative stress. Manganese superoxide dismutase (MnSOD), located in the mitochondrial matrix, is a key enzyme that neutralizes superoxide radicals (O), maintaining cellular redox balance and integrity. This review examines the development and therapeutic potential of MnSOD mimetics-synthetic compounds designed to replicate MnSOD's antioxidant activity.

Despite promising preliminary biology, natural products isolation efforts may be confounded when the active compound is not isolated during bioassay-guided purification or classical pharmacognostic research investigations. A more rational isolation procedure connecting the polypharmacology of an herb to its individual constituents must be applied to better detect bioactive molecules before tedious analytical steps are considered. While (yohimbe) has been traditionally used in herbal medicine as a general tonic, an aphrodisiac, a performance enhancer, and an integral part of various dietary supplements, the hydroethanolic extract of yohimbe was identified to possess at least 3-4-fold induction of the pregnane X receptor (PXR) at 30 μg/mL, a key nuclear receptor implicated in adverse interactions, .
