Minocycline (7-dimethylamino-6-dimethyl-6-deoxytetracycline) is a second-generation tetracycline that can cross the blood-brain barrier and has anti-inflammatory and neuroprotective effects. The potential of minocycline as a drug for treating Huntington's disease has been studied; however, the molecular mechanism underlying the neuroprotective properties of minocycline remains elusive. In this ...

Introduction: Although aging is the most important risk factor for Alzheimer's disease (AD), there is evidence indicating that neuroinflammation may contribute to the development and progression of the disease. Several studies indicated that minocycline may exert neuroprotective effects in rodent models of neurodegenerative diseases. Nevertheless, there are also other studies implying that ...

Minocycline, a broad spectrum antibiotic, has been discovered to have inhibitory activity against HIV-1 in vitro, but the targets inhibited are unknown. We used a docking with dynamics protocol developed by us to predict the binding affinities of minocycline against seven active sites of five HIV-1 proteins to putatively identify the potential target(s) of minocycline. The results indicate that...

Cutaneous hyperpigmentation is a recognized adverse effect of chronic minocycline use occurring in up to 50% of patients. In this report we present a rare case of extensive skin hyperpigmentation involving both lower extremities in a patient receiving long term minocycline. The patient was receiving minocycline as suppression for chronic prosthetic joint infection. Risk factors associated with ...

Background: Minocycline is a second-generation tetracycline with apparent neuroprotective effects. It reportedly blocks the activation of microglia, preventing the release of cytokines that are believed to contribute to schizophrenia. Minocycline also helps to maintain normal glutamatergic neurotransmission. Although the exact mechanism is unknown, results of animal studies and several human tr...

BACKGROUND AND PURPOSE Minocycline, a semisynthetic tetracycline antibiotic, has been reported to ameliorate brain injury and inhibit microglial activation after focal cerebral ischemia. However, the cerebroprotective mechanism of minocycline remains unclear. In the present study, we investigated that mechanism of minocycline in a murine model of 4-hour middle cerebral artery (MCA) occlusion. ...

Minocycline is an inhibitor of matrix metalloproteinases (MMPs) and has been shown to have analgesic effects. Whilst increased expression of MMPs is associated with neuropathic pain, MMPs also play crucial roles in Wallerian degeneration and nerve regeneration. In this study we examined the expression of MMP-2, MMP-9 and tissue inhibitor of metalloproteinase (TIMP)-1/-2 in the sciatic nerve of ...
