The behavioral actions of some novel aporphines have been examined in rats with selective unilateral 6-hydroxydopamine (6OHDA)-induced destruction of nigrostriatal dopaminergic neurons, and in rats with bilateral 6OHDA-induced destruction of mesolimbic dopaminergic neurons. Dopaminomimetics such as apomorphine (APO) in these

Syntheses of (R)-(-)-2-methoxyapomorphine (R-8), its antipode S-8, and its (R)-(-)-N-n-propyl R-9 derivatives are described. The dopaminergic receptor affinities of these compounds and their 2-unsubstituted counterparts (R)-(-)-apomorphine (R(-)-APO, R-1), (S)-(+)-apomorphine (S(+)-APO, S-1), and (R)-(-)-N-n-propylnorapomorphine (R(-)-NPA, R-2), as well as those of

The purpose of this study was to correlate potential mechanisms with site(s) of action for TNPA-induced ocular hypotension. In response to R(-)-2, 10, 11-trihydroxy-N-propyl-noraporphine hydrobromide (TNPA, 75 microg), a D2 dopamine receptor agonist, the intraocular pressure decreased by 4.5 and

(-)-2,10,11-Trihydroxy-N-n-propylnoraporphine (TNPA,2c) has been synthesized from thebaine (3a), via northebaine (3b), normorphothebaine (2a), and alkylation to the N-propyl derivative 2b. O-Demethylation gave the desired product 2c. Compound 2c showed activity comparable to its 10,11-dihyroxy counterpart (NPA, 1b) on the stimulation
