N-Methyl-1-(naphthalen-2-yl)propan-2-amine (methamnetamine, PAL-1046) is an amphetamine-based new psychoactive substance (NPS). Methamnetamine has been reported to cause excessive release of serotonin, and it is classified as an empathogen or entactogen. It is not regulated as a controlled substance in most countries, and there are no studies on its metabolism. In this study, in vitro phase I metabolism of methamnetamine in human liver microsomes (HLM) and flavin-containing monooxygenase (FMO…

It is concluded that low-efficacy partial DAT substrates promote efflux at a slower rate than full substrates, and “partiality” reflects the ultra-slow K2 constant, which functionally limits the ability of these compounds to increase extracellular DA.
A kinetic account for amphetamine-induced monoamine release
- BiologyThe Journal of general physiology
- 2018
A kinetic model was developed, which allowed for random, but cooperative, binding of substrate and Na+ (or K+) and accounted for the releasing action of amphetamines without any digression from alternating access and is the first to provide a mechanistic framework for amphetamine-induced monoamine release.
