Conformational preferences of the potent dopamine reuptake blocker BTCP and its analogs and their incorporation into a pharmacophore model
Molecular mechanics calculations using MM3-92 and ab initio quantum mechanical calculations using SPARTAN 5.0 were performed on the structurally similar PCP and BTCP, in which only the latter has a cocaine-lik...

Crystal Structures of Analogs of threo-Methylphenidate
The crystal structures of the chloride salts of five analogs of threo-methylphenidate have been obtained. Four of these have different substituents on the phenyl ring while the fifth is the ethyl ester of methylp...

Structural Factors that Distinguish Dopamine D1 and D2 Agonists
To determine the structural features responsible for their selectivity as dopamine D1 agonists, a conformational analysis has been performed on an analog of nomifensine, dihydrexidine, a benzergoline, and an ...
