Monoamine oxidase-A (MAO-A) (amiflamine (AMF) and 4-methylthioamphetamine (MTA)) and MAO-B (l-deprenyl) inhibitors were found to be cytotoxic in a concentration-dependent manner for RCHT cells derived from adult rat hypothalamus. The cytotoxic effects were increased when the inhibitors were co-incubated with dicoumarol and especially with 25 μM AMF+100 μM(More)
Halogenation of the aporphine alkaloid boldine at the 3-position leads to increased affinity for rat brain D(1)-like dopaminergic receptors with some selectivity over D(2)-like receptors. A series of 3-halogenated and 3,8-dihalogenated (halogen=Cl, Br or I) derivatives of predicentrine (9-O-methylboldine) and glaucine (2,9-di-O-methylboldine) were prepared(More)
(+/-)-4-Methylthioamphetamine (MTA) was resolved into its enantiomers, and a series of N-alkyl derivatives of the parent compound, as well as its alpha-ethyl analogue, were prepared. The monoamine oxidase (MAO) inhibitory properties of these substances were evaluated in vitro, using a crude rat brain mitochondrial suspension as the source of enzyme. All(More)
Amphetamine derivatives have therapeutic potential in diseases such as attention deficit hyperactivity disorder, narcolepsy and obesity. However, their prolonged use has been associated with cardiovascular toxicity and addiction. In recent years, we have studied the pharmacological effects of amphetamine derivatives such as methylthioamphetamine (MTA) and(More)
