Methylone - Wikipedia
Methylone is a psychoactive substance that acts on monoaminergic systems and produces effects such as euphoria, empathy and enhanced perception. It is a slight modification of MDMA, but has lower potency, faster onset and shorter duration.
Methylone screening with electropolymerized molecularly imprinted ...
Aug 1, 2020 · The molecular imprinting of methylone was achieved by electropolymerization of a solution of 15 mmol L −1 2-MBI and 5 mmol L −1 methylone, in pH 7.4 PBS, on a SPAuE. A suitable methylone-templated MIP was achieved by 15 cyclic voltammograms between −0.2 and 1.3 V, at a scan rate of 50 mV s −1.
Methylone and MDPV activate autophagy in human …
May 19, 2017 · Methylone and MDPV prompted the formation of acidic vesicular organelles (AVOs) and lead to increased expression of the autophagy-associated protein LC3-II in a concentration- and time-dependent manner. Electron microscopy confirmed the presence of autophagosomes with typical double membranes and autolysosomes in cells exposed to both β …
