Abstract:


In this review we explore and integrate the knowledge of the plausible pharmacological targets that could explain the new application for the well known semi-synthetic, tetracycline-derivate minocycline as a cytoprotective drug. In doing so, we will analyze the possible mechanisms to elucidate the potential cytoprotective properties of minocycline. We address its anti-oxidant action ranging from its structure to its capacity to modulate the expression of oxidant-related enzymes such as nitric oxide synthase. The pharmacological targets responsible for its anti-inflammatory effects are surveyed. The effects of this antibiotic are making its marks on intracellular pathways related to neurodegenerative processes such as mitochondrially-mediated apoptosis, including minocycline-modulated effects on the expression of apoptotic proteins. Finally, we will explore the effects of minocycline on metalloproteinases, enzymes implicated in the modulation of cerebrovascular post-ischemic oxidative reperfusion injury, and new targets. In conclusion, we shed new light on the shadowy controversy of minocyclines potential cytoprotective mechanisms and targets of action.
