- Co-administration of dopamine-receptor binding compounds
-
Methods for treating a patient having neurological, psychotic, and psychiatric disorders are described comprising the steps of administering to the patient an effective amount of a partial and/or full dopamine D1 receptor agonist, and administering to the patient an effective amount of a dopamine D2 receptor antagonist. Pharmaceutical compositions comprising a dopamine D1 receptor agonist and a dopamine D2 receptor antagonist are also described. The D1 dopamine receptor agonist and the D2 dopamine receptor antagonist can be administered to the patient in the same or in a different composition or compositions.

- (+)-Dinapsoline: An efficient synthesis and pharmacological profile of a novel dopamine agonist
-
A highly convergent synthesis was developed for the novel dopamine agonist dinapsoline (12) (Ghosh, D.; Snyder, S. E.; Watts, V. J.; Mailman, R. B.; Nichols, D. E. 8,9-Dihydroxy-2,3,7, 11b-tetrahydro-1H-naph[1,2,3-de]isoquinoline: A Potent Full Dopamine D1 Agonist Containing a Rigid β-Phenyldopamine Pharmacophore. J. Med. Chem. 1996, 39 (2), 549-555). The crucial step in the new synthesis was a free radical-initiated cyclization to give the complete dinapsoline framework. The improved synthesis required half as many steps as the original procedure (Nichols, D. E.; Mailman, R.; Ghosh, D. Preparation of novel naphtho[1,2,3-de]isoquinolines as dopamine receptor ligands. PCT Int. Appl. WO 9706799 A1, Feb 27, 1997). One of the late-stage intermediates (11) was resolved into a pair of enantiomers. From there, the (R)-(+)-12 (absolute configuration by x-ray) of dinapsoline was identified as the active enantiomer. In unilateral 6-hydroxydopamine (6-OHDA)-lesioned rats, (+)-dinapsoline showed robust rotational behavior comparable to that of an external benchmark, trans- 4,5,5a,6,7,11b-hexahydro-2-propylbenzo[f]thieno[2,3-c]quinoline-9,10-diol, hydrochloride 18 (Michaelides, M. R.; Hong, Y. Preparation of heterotetracyclic compounds as dopamine agonists. PCT Int. Appl. WO 9422858 A1, Oct 13, 1994).

- New diarylmethylpiperazines as potent and selective nonpeptidic δ opioid receptor agonists with increased in vitro metabolic stability
-
Nonpeptide δ opioid agonists are analgesics with a potentially improved side-effect and abuse liability profile, compared to classical opioids. Andrews analysis of the NIH nonpeptide lead SNC-80 suggested the removal of substituents not predicted to contribute to binding. This approach led to a simplified lead, N,N-diethyl-4-[phenyl(1-piperazinyl)methyl]benzamide (1), which retained potent binding affinity and selectivity to the human δ receptor (IC50 = 11 nM, μ/δ = 740, κ/δ > 900) and potency as a full agonist (EC50 = 36 nM) but had a markedly reduced molecular weight, only one chiral center, and increased in vitro metabolic stability. From this lead, the key pharmacophore groups for δ receptor affinity and activation were more clearly defined by SAR and mutagenesis studies. Further structural modifications on the basis of 1 confirmed the importance of the N,N-diethylbenzamide group and the piperazine lower basic nitrogen for δ binding, in agreement with mutagenesis data. A number of piperazine N-alkyl substituents were tolerated. In contrast, modifications of the phenyl group led to the discovery of a series of diarylmethylpiperazines exemplified by N,N-diethyl-4-[1-piperazinyl(8-quinolinyl)-methyl]benzamide (56) which had an improved in vitro binding profile (IC50 = 0.5 nM, μ/δ = 1239, EC50 = 3.6 nM) and increased in vitro metabolic stability compared to SNC-80.
