  Synthesis and biological activity of 2-Carbomethoxy-3-catechol-8-azabicyclo[3.2.1]octanes

  摘要：

  Cocaine inhibits the dopamine transporter and the consequent elevation of dopamine is thought to contribute to the addictive properties of cocaine. Tropane analogues of cocaine, targeted to the dopamine transporter (DAT), are a significant focus of drug design for cocaine addiction medications. Herein, we report the function of the ortho hydroxy substituents in dopamine with respect to the azabicyclo[3.2.1]octane skeleton. The introduction of the o-dihydroxyl functionality led to reduced binding potency at monoamine transporters, rather than enhanced interaction with the DAT. It is therefore likely that the binding site for these compounds on the DAT is not the same as that for dopamine. Notwithstanding the moderate potency of the free catechols (> 100 nM), 7 manifested stimulant activity with a duration of effect that exceeded 4 h in a rat locomotor activity assay. Compound 10, a diacetoxy prodrug for 7, substituted fully for cocaine in a rat drug-discrimination paradigm and is now undergoing further investigation as a potential medication for cocaine abuse.

• Rotational Energy Barrier around the C1–C11 Single Bond in Lamellarins: A Study by Variable-Temperature NMR
  作者：Masatomo Iwao、Tsutomu Fukuda、Ryosuke Itoyama、Terufusa Minagawa

  DOI：10.3987/com-13-s(s)69

  日期：——

  In order to estimate the free energy barrier to rotation around the C1-C11 single bond in lamellarins, new lamellarin analogues (1a), (1b), (2a), and (2b) possessing diastereotopic protons or carbons at the C1 aryl moiety were synthesized. Variable-temperature H-1 and C-13 NMR measurements of these analogues revealed that the free energy barriers to rotation around the C1-C11 axis in 5,6-saturated and 5,6-unsaturated lamellarins were around 72-74 and 83-87 kJ/mol, respectively.
