2-Carbomethoxy-3-aryl-8-bicyclo[3.2.1]octanes: Potent Non-Nitrogen Inhibitors of Monoamine Transporters
摘要:
Cocaine is a potent central nervous system stimulant with severe addiction liability. Its reinforcing and stimulant properties derive from inhibition of monoamine transport systems, in particular the dopamine transporter (DAT). This inhibition results in an increase in synaptic dopamine with subsequent stimulation of postsynaptic dopamine receptors. A wide variety of ligands manifest potent inhibition of the DAT, and these ligands include 3-aryltropane as well as 8-oxa-3-aryltropane analogues of cocaine. There has been considerable effort to determine structure-activity relationships of cocaine and congeners, and it is becoming clear that these inhibitors do not all interact with the DAT in the same manner. The functional role of the 8-heteroatom is the focus of this study. We describe the preparation and biology of a series of 2-carbomethoxy-3-arylbicyclo[3.2.1]octane analogues. Results show that methylene substitution of the amine or ether function of the 8-hetero-2-carbomethoxy-3-arylbicyclo[3.2.1]octanes yields potent inhibitors of monoamine transport. Therefore neither nitrogen nor oxygen are prerequisites for binding of tropane-like ligands to monoamine transporters.

design of potential cocaine antagonists or cocaine substitutes which interact at the dopamine transporter of mammalian systems. This manuscript describes the synthesis and biological evaluation of 8-substituted 2-carbomethoxy-3-arylbicyclo[3.2.1]oct-2-enes. These compounds prove potent and selective inhibitors of the dopamine transporter. Their selectivity results primarily from a reduced inhibitory potency
The present invention relates to the therapeutic use of non-amine tropane analogues that bind to the SERT to treat neuropsychiatric disorders.
本发明涉及治疗非胺类曲梯巴酮类似物与SERT结合以治疗神经精神障碍的用途。
