2-Isoxazol-3-Phenyltropane Derivatives of Cocaine: Molecular and Atypical System Effects at the Dopamine Transporter

The locomotor-stimulant effects of RTI-371 were comparable in wild-type and knockout cannabinoid CB1 receptor (CB1R) mice, indicating that previously reported CB1 allosteric effects do not decrease cocaine-like effects ofRTi-371.

2-Substituted 3β-Aryltropane Cocaine Analogs Produce Atypical Effects without Inducing Inward-Facing Dopamine Transporter Conformations

Behavioral, biochemical, and computational results show that aryltropane analogs can bind to the DAT and stabilize outward-facing DAT conformations like cocaine, yet produce effects that differ from those of cocaine.

Influence of chronic dopamine transporter inhibition by RTI-336 on motor behavior, sleep, and hormone levels in rhesus monkeys.

Chronic treatment with RTI-336 has a mild but significant stimulant effect, as evidenced by the significant increase in activity during the evening period which may cause minor disruptions in sleep measures.

Synthesis and Pharmacological Evaluation of 6-Acetyl-3-(4-(4-(4-fluorophenyl)piperazin-1-yl)butyl)benzo[d]oxazol-2(3H)-one (SN79), a Cocaine Antagonist, in Rodents

The ability of SN79 to significantly attenuate the acute and subchronic effects of cocaine provides a promising compound lead to the development of an effective pharmacotherapy against cocaine.

The Atypical Stimulant and Nootropic Modafinil Interacts with the Dopamine Transporter in a Different Manner than Classical Cocaine-Like Inhibitors

Modafinil displayed affinity ratios similar to those of benztropine, GBR12909 and bupropion, but far different than those of cocaine, β-CFT or methylphenidate, and it was demonstrated that the conformational effects of a given DAT inhibitor influence its phenomenological effects.

Medication Development for the Treatment of Cocaine Addiction – Progress at Preclinical and Clinical Levels

This review article will focus on those medication strategies that are well-studied in experimental animals and are currently under clinical trials for the treatment of addiction or for other diseases, including DAT-based agonist therapy, DA receptor-based antagonist therapy, glutamate- based therapy, GABA-based therapy and endocannabinoid-based Therapy.

Cocaine Interaction with Dopamine Transporter in the Prefrontal Cortex and Beyond

Although the relevant research investment in understanding the mechanism of action of cocaine and its role in altering brain circuits and behaviour has not been found yet, cocaine use, dependence, abuse and addiction are still a relevant health, social, and economical problem.

Models of Neurological Disease (Substance Abuse): Self‐Administration in Monkeys

Procedures for studying intravenous drug self‐administration in large primates, such as rhesus macaques, and smaller primates,such as squirrel monkeys are described.



Effects of Combined Dopamine and Serotonin Transporter Inhibitors on Cocaine Self-Administration in Rhesus Monkeys

Results indicate that combined inhibition of DAT and SERT warrants consideration as a viable approach in the development of cocaine medications.

The Reinforcing Efficacy of the Dopamine Reuptake Inhibitor 2β-Propanoyl-3β-(4-tolyl)-tropane (PTT) as Measured by a Progressive-Ratio Schedule and a Choice Procedure in Rhesus Monkeys

Results suggest that the reinforcing efficacy of PTT is less than cocaine in nonhuman primates, and indicate that slow-onset, long-acting DAT inhibitors can decrease cocaine self-administration while not functioning robustly as reinforcers, and support the further investigation of these drugs as treatment for cocaine addiction.

The Reinforcing Efficacy of Psychostimulants in Rhesus Monkeys: The Role of Pharmacokinetics and Pharmacodynamics

There was not a linear relationship between monoamine transporter affinity and reinforcing efficacy, but it appeared that in nonhuman primates there is a range of DAT affinity under which maximal responding is maintained, and the 5-HTT-selective cocaine analog HD-60 functioned robustly as a reinforcer at several doses in all monkeys tested.

The reinforcing and discriminative stimulus effects of the novel cocaine analog 2beta-propanoyl-3beta-(4-tolyl)-tropane in rhesus monkeys.

It is demonstrated that the long-acting indirect dopamine agonist PTT was effective in decreasing cocaine self-administration and in abuse liability testing showed a unique behavioral profile, not functioning as a reinforcer when substituted for cocaine and producing discriminative stimulus effects similar to cocaine.

Effects of cocaine and related drugs in nonhuman primates. III. Self-administration by squirrel monkeys.

The results in conjunction with those of previous studies in squirrel monkeys reveal a close correspondence between the relative potencies of cocaine and related drugs for maintaining i.v. self-administration and for increasing rates of schedule-controlled responding, suggesting that the reinforcing and psychomotor-stimulant effects of the drugs are mediated similarly.

Reinforcing Strength of a Novel Dopamine Transporter Ligand: Pharmacodynamic and Pharmacokinetic Mechanisms

The results suggest that (+)-CPCA is a weaker positive reinforcer than cocaine because it has a slower onset of action over the first few minutes after i.v. injection.

Further evaluation of the reinforcing effects of the novel cocaine analog 2β-propanoyl-3β-(4-tolyl)-tropane (PTT) in rhesus monkeys

It is suggested that for long-acting compounds like PTT, reinforcing effects are more likely to be observed when the drug is available under a ratio-based schedule, compared to an interval- based schedule.

Self-administration of two long-acting monoamine transport blockers in rhesus monkeys

The results indicate that the reinforcing effects of PTT were slightly modified by a brief history of cocaine reinforcement, and that the weak reinforcing effects were most apparent when the drug was available under unlimited-access conditions.
