Reinforcing properties of fencamfamine: Involvement of dopamine and opioid receptors
Fencamfamine (FCF) is a psychostimulant classified as an indirect dopamine agonist. The conditioning place preference (CPP) paradigm was used to investigate the reinforcing properties of FCF. After initial preferences had ...
Functional roles of T3.37 and S5.46 in the activation mechanism of the dopamine D1 receptor
(Springer Verlag, 2017)
© 2017, Springer-Verlag Berlin Heidelberg. The activation mechanism of dopamine receptors is unknown. The amino acids S5.42, S5.43, and S5.46 located in helix 5 appear to be crucial, but their specific roles in receptor ...
Behavioral indices of moderate nigrostriatal 6–hydroxydopamine lesion: a preclinical Parkinson's model.
Asymmetries in turning and scanning were investigated in rats with different degrees of neostriatal dopamine depletion after unilateral injections of 6-hydroxydopamine into the substantia nigra. Animals with severe lesions, ...
Theoretical study of dopamine. Application of the HSAB principle to the study of drug-receptor interactions
We present a theoretical conformational study of neutral and N- protonated form of dopamine in which we relate its pharmacological activity to the chemical hardness. We have found that the neutral form presents small ...
Targeting dopamine receptor D3 signalling in inflammation

DAILY VARIATION IN PLASMA-CONCENTRATION OF FENCAMFAMINE AND STRIATAL DOPAMINE-RECEPTORS IN RATS
(Associação Brasileira de Divulgação Científica (ABRADIC), 1994-03-01)
Fencamfamine (FCF) is a psychostimulant drug classified as an indirect dopamine agonist. In the present study we evaluated the daily variation in plasma FCF concentration and in striatal dopamine receptors. Adult male ...
3-Chlorotyramine acting as ligand of the d2 dopamine receptor: molecular modeling, synthesis and d2 receptor affinity
(Wiley VCH Verlag, 2015-02)
We synthesized and tested 3-chlorotyramine as a ligand of the D2 dopamine receptor. This compound displayed a similar affinity by this receptor to that previously reported for dopamine. In order to understand further the ...
