  • Title: A prodrug of ADTN: selectivity of dopaminergic action and brain levels of ADTN.
    Author: Horn AS, Kelly P, Westerink BH, Dijkstra D.
    Journal: Eur J Pharmacol; 1979 Nov 23; 60(1):95-9. PubMed ID: 574829.
    Abstract:
    The effects of administration of the prodrug dibenzoyl ADTN (DBADTN) on ADTN concentrations in rat brain and on behaviour in rats having a unilateral 6-hydroxydopamine lesion in the corpus striatum have been studied. Using a combination of HPLC and electrochemical detection as assay method it was found that there was a more selective accumulation of ADTN in the corpus striatum than in the cerebellum. In addition the accumulation of ADTN in the corpus striatum was slow in onset yet long in duration. The peak concentration of ADTN was relatively low and although it was sufficient to cause a strong stimulation of presynaptic DA receptors it did not cause significant rotation in the unilaterally lesioned rat. Prodrug methodology may thus prove useful in designing new selectively acting DA agonists.
