Popis: | In an attempt to enhance the potency of the dopamine autoreceptor agonist 3-PPP, racemic cis-3-(3-hydroxyphenyl)-5-[(methylmercapto)methyl]-N-n-propylpiperidine has been prepared in a stereoselective synthesis. NMR studies of 3 show a diequatorial conformation for the 3- and 5-substituents, which gives compound 3 an intriguing overlap with the ergoline derivative pergolide. Pharmacological testing revealed that 3, which is a 5-(methylmercapto)methyl derivative of racemic 3-PPP does not show the anticipated potency increase as a dopamine autoreceptor agonist. In vitro (inhibition of tyrosine hydroxylation) 3 and 1 have similar potency, and the in vivo potency (inhibition of GBL accelerated dopamine synthesis) of 3 is inferior to that of 1. |
