Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

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.

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).

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.
