Description:

WARNING: This product is for research use only, not for human or veterinary use.

Neostigmine is a cholinesterase inhibitor used in the treatment of myasthenia gravis and to reverse the effects of muscle relaxants such as gallamine and tubocurarine. Neostigmine, unlike PHYSOSTIGMINE, does not cross the blood-brain barrier.

Product Data
Biological target:
Neostigmine Bromide is a cholinesterase inhibitor used in the treatment of myasthenia gravis.
In vitro activity:
In this study, the cytotoxicity, genotoxicity and apoptotic effects of Sugammadex and Neostigmine on HEK-293 cells were analyzed with using the MTT, Comet Assay and Flow Cytometric Annexin-V methods, respectively. The results demonstrate that Neostigmine at 50, 100, 250, and 500 µg/mL is more cytotoxic than equivalent dosages of Sugammadex. Neostigmine at 500 and 1000 µg/mL was found to be more genotoxic, and Neostigmine at 500 µg/mL had a statistically higher risk of causing apoptosis and necrosis than Sugammadex (p<0.05).

In vivo activity:
In this sense, the aim of this study is to investigate the effects of treatment with neostigmine, known for the ability to control lung inflammation, on oxidative stress in the cerebral cortex of asthmatic mice. Female BALB/cJ mice were submitted to asthma model induced by ovalbumin (OVA). Control group received only Dulbecco's phosphate-buffered saline (DPBS). To evaluate neostigmine effects, mice received 80 μg/kg of neostigmine intraperitoneally 30 min after each OVA challenge. The results revealed for the first time that treatment with neostigmine (an acetylcholinesterase inhibitor that no crosses the BBB) was able to revert ROS production and change anti-oxidant enzyme catalase in the cerebral cortex in asthmatic mice.
