摘要: Methcathinone and methylone, the beta-ketone analogues of methamphetamine 3,4-methylenedioxymethamphetamine (MDMA), respectively, were tested for neurotransmitter uptake inhibition in vitro. The beta-ketones threefold less potent than nonketo drugs at inhibiting platelet serotonin accumulation, with IC(50)'s 34.6+/-4.8 microM 5.8+/-0.7 microM, respectively. methylone similar potency to MDMA catecholamine transporters individually expressed transfected glial cells. For dopamine uptake, 0.36+/-0.06 0.82+/-0.17 respectively; noradrenaline IC(50) values 0.51+/-0.10 1. 2+/-0.1 In chromaffin granules, accumulation 112+/-8.0 methcathinone 166+/-12 10-fold higher respective MDMA. Our results indicate that potently inhibit plasma membrane but only weakly vesicle transporter.
