  Deconstruction of the α4β2 Nicotinic Acetylcholine Receptor Positive Allosteric Modulator Desformylflustrabromine

  摘要：

  Desformylflustrabromine (dFBr; 1), perhaps the first selective positive allosteric modulator of alpha 4 beta 2 neuronal nicotinic acetylcholine (nACh) receptors, was deconstructed to determine which structural features contribute to its actions on receptors expressed in Xenopus ooycytes using two-electrode voltage clamp techniques. Although the intact structure of 1 was found to be optimal, several deconstructed analogs retained activity. Neither the 6-bromo substituent nor the entire 2-position chain is required for activity. In particular, reduction of the olefinic side chain of 1, as seen with 6, not only resulted in retention of activity/potency but in enhanced selectivity for alpha 4 beta 2 versus alpha 7 nACh receptors. Pharmacophoric features for the allosteric modulation of alpha 4 beta 2 nACh receptors by 1 were identified.

  brominated marine alkaloids arborescidine A (1), B (2) and C (3), starting from 6-bromo-(N-methyl) trypatamine is described. An equilibrium, under both basic and acidic conditions was found to exist between the trans- and cis-isomers 3 and 4. Spectral data indicated that the structure of isomer 4 does not correspond with the compound identified as arborescidine D recently isolated from the marine tunicate

  In this study thirty-three novel indole derivatives were designed and synthesized based on the structure of deformylflustrabromine B (1), a metabolite isolated from the marine bryozoan Flustra foliacea L. The syntheses were carried out using standard methodologies and in good yields. The molecules were tested for their affinities for the alpha 4 beta 2*, alpha 3 beta 4*, alpha 7* and (alpha 1)(2)beta 1 gamma delta nicotinic acetylcholine receptor (nAChR) sub-types. Binding assays showed that, among these ligands, compound 7c exhibited the highest affinity with K-i = 136.1, 93.9 and 862.4 nM for the alpha 4 beta 2*, alpha 3 beta 4*, and alpha 7* nAChRs subtypes, respectively. These results indicated that the indole core might be a useful scaffold for the development of new potent and selective nAChR ligands. (C) 2012 Elsevier Ltd. All rights reserved.

  Desformylflustrabromine (dFBr; 1) and desformylflustrabromine-B (dFBr-B; 2) have been previously isolated from natural sources, and the former has been demonstrated to be a novel and selective positive allosteric modulator of alpha 4 beta 2 nicotinic acetylcholine (nACh) receptors. The present study describes the synthesis of water-soluble salts of I and 2, and confirms and further investigates the actions of I and 2 using two-electrode voltage clamp recordings.
