  Phase I metabolites of mephedrone display biological activity as substrates at monoamine transporters

  摘要：

  Background and Purpose4‐Methyl‐N‐methylcathinone (mephedrone) is a synthetic stimulant that acts as a substrate‐type releaser at transporters for dopamine (DAT), noradrenaline (NET) and 5‐HT (SERT). Upon systemic administration, mephedrone is metabolized to several phase I compounds: the N‐demethylated metabolite, 4‐methylcathinone (nor‐mephedrone); the ring‐hydroxylated metabolite, 4‐hydroxytolylmephedrone (4‐OH‐mephedrone); and the reduced keto‐metabolite, dihydromephedrone.Experimental ApproachWe used in vitro assays to compare the effects of mephedrone and synthetically prepared metabolites on transporter‐mediated uptake and release in HEK293 cells expressing human monoamine transporters and in rat brain synaptosomes. In vivo microdialysis was employed to examine the effects of i.v. metabolite injection (1 and 3 mg·kg−1) on extracellular dopamine and 5‐HT levels in rat nucleus accumbens.Key ResultsIn cells expressing transporters, mephedrone and its metabolites inhibited uptake, although dihydromephedrone was weak overall. In cells and synaptosomes, nor‐mephedrone and 4‐OH‐mephedrone served as transportable substrates, inducing release via monoamine transporters. When administered to rats, mephedrone and nor‐mephedrone produced elevations in extracellular dopamine and 5‐HT, whereas 4‐OH‐mephedrone did not. Mephedrone and nor‐mephedrone, but not 4‐OH‐mephedrone, induced locomotor activity.Conclusions and ImplicationsOur results demonstrate that phase I metabolites of mephedrone are transporter substrates (i.e. releasers) at DAT, NET and SERT, but dihydromephedrone is weak in this regard. When administered in vivo, nor‐mephedrone increases extracellular dopamine and 5‐HT in the brain whereas 4‐OH‐mephedrone does not, suggesting the latter metabolite does not penetrate the blood–brain barrier. Future studies should examine the pharmacokinetics of nor‐mephedrone to determine its possible contribution to the in vivo effects produced by mephedrone.

  The strategy of stereodivergent reactions on racemic mixtures (stereodivergent RRM) was employed for the first time in intramolecular benzoin reactions and led to the rapid access of chromanones/flavanones with two consecutive stereocenters. The easily separable stereoisomers of the products were obtained with moderate to excellent enantioselectivities in a single step. Catechol type additives proved

  Abstract Aromatic α-bromo ketones and α-iodio ketones can be reduced by bismuth prepared from NaBH4 and BiCl3 in water to their parent ketones in high yields, but aromatic α-chloro ketones should be added to sodium iodide first.

  An efficient and mild method for reductive C–O bond cleavage of lignin β-O-4 ketone models was developed to afford the corresponding ketones and phenols with PDI-CoCl2 as the precatalyst and diboron reagent as the reductant. The synthetic utility of the methodology was demonstrated by depolymerization of a polymeric model and gram-scale transformation. Mechanistic studies suggested that this transformation
