  Synthesis and evaluation of a series of tropane analogues as novel vesicular monoamine transporter-2 ligands

  摘要：

  A series of tropane derivatives has been synthesized as lobelane analogues and evaluated for their binding affinity at the vesicular monoamine transporter-2 (VMAT2), and at alpha 4 beta 2* and alpha 7* nicotinic acetylcholine receptors. The trop-2-ene analogues 4a and 4b exhibited good affinity and high selectivity for VMAT2. (c) 2005 Elsevier Ltd. All rights reserved.

  The cytotoxic properties and preferential toxicity to tumour cells displayed by some 2,4-bis(benzylidene)-8-methyl-8-azabicyclo[3.2.1] octan-3-ones and 3,5-bis(benzylidene)-1-methyl-4-piperidones

  摘要：

  This study demonstrated that replacement of the axial protons on the C2 and C6 atoms of various 1-methyl-3,5-bis(benzylidene)-4-piperidones 3 by a dimethylene bridge leading to series 2 lowered cytotoxic potencies. Four compounds 2a and 3a-c emerged as lead molecules based on their toxicity towards different neoplasms and their selective toxicity for malignant rather than normal cells. Some possible reasons for the disparity between the IC50 values in the two series of compounds are presented based on molecular modeling, log P values and respiration in rat liver mitochondria.
