Biological Activity

Description Minocycline HCl is the most lipid soluble and most active tetracycline antibiotic, binds to the 30S ribosomal subunit, preventing the binding of tRNA to the mRNA-ribosome complex and interfering with protein synthesis.
In vitro

Minocycline is a second-generation tetracycline used in humans, which effectively crosses the blood−brain barrier. It inhibits the activity of caspase-1, caspase-3, inducible form of nitric oxide synthetase (iNOS) and p38 mitogen-activated protein kinase (MAPK). After experimental ischemia, minocycline inhibits caspase-1 and inducible nitric oxide synthetase (iNOS) upregulation, and decreases infarct size. Minocycline inhibits mitochondrial permeability-transition-mediated cytochrome c release. Minocycline-mediated inhibition of cytochrome c release is demonstrated in vivo, in cells, and in isolated mitochondria. [2]

In vivo

Minocycline is a semi-synthetic tetracycline derivative which is well absorbed and distributed in body tissues and is suitable for twice daily administration. Minocycline's effects are related to the inhibition of protein synthesis. Although minocycline's broader spectrum of activity, compared to other members of the group, includes activity against Neisseria meningitidis, its use as a prophylaxis is no longer recomended because of side effects (dizziness and vertigo). [1]

Minocycline is remarkable neuroprotective qualities in models of cerebral ischaemia, traumatic brain injury, and Huntington's and Parkinson's disease. The neuroprotective action of minocycline may include its inhibitory effect on 5-lipoxygenase, an inflammatory enzyme associated with brain aging. [3]
