Abstract:
In our continued exploration of trishomocubane derivatives with central nervous system (CNS) activity, N-arylalkyl-8-aminopentacyclo[5.4.0.0(2,6).0(3,10).0(5,9)]undecanes (10-13) displaying affinity for the sigma (σ) receptor were also found, in several cases, to interact with the dopamine transporter (DAT). Compound 12 was identified as the first trishomocubane-derived high affinity DAT ligand (K(i) = 1.2 nM), with greater than 8300-fold selectivity over the monoamine transporters NET and SERT, and only low to moderate affinity for σ(1) and σ(2) receptors.

Adrenergic Agonists: Indirect-Acting Agents
One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral bioavailability, and...
