  4-(Phosphonoalkyl)- and 4-(phosphonoalkenyl)-2-piperidinecarboxylic acids: synthesis, activity at N-methyl-D-aspartic acid receptors and anticonvulsant activity

  摘要：

  A series of 4-(phosphonoalkyl)- and 4-(phosphonoalkenyl)-2-piperidinecarboxylic acids were synthesized, and their biological activity was assessed as competitive ligands for the NMDA receptor, both in vitro by using a receptor binding assay ([3H]CGS 19755 binding) and in vivo by using an NMDA seizure model in mice. The analogues were also evaluated in [3H]AMPA and [3H]kainate binding to assess their affinity for non-NMDA excitatory amino acid receptor subtypes. A number of these analogues show potent and selective NMDA antagonistic activity both in vitro and in vivo. Most notable are 4-(phosphonomethyl)-2-piperidinecarboxylic acid (1a) (CGS 19755) and the phosphonopropenyl analogue 1i, both of which show anticonvulsant activity in the 1-2 mg/kg ip range. With the aid of computer-assisted modeling, a putative bioactive conformation for AP-5 is hypothesized from the SAR data presented and a preliminary model for the antagonist-preferring state of the NMDA receptor is presented.

  Design, biological evaluation and X-ray crystallography of nanomolar multifunctional ligands targeting simultaneously acetylcholinesterase and glycogen synthase kinase-3

  摘要：

  Both cholinesterases (AChE and BChE) and kinases, such as GSK-3 alpha/beta, are associated with the pathology of Alzheimer's disease. Two scaffolds, targeting AChE (tacrine) and GSK-3 alpha/beta (valmerin) simultaneously, were assembled, using copper(I)-catalysed azide alkyne cycloaddition (CuAAC), to generate a new series of multifunctional ligands. A series of eight multi-target directed ligands (MTDLs) was synthesized and evaluated in vitro and in cell cultures. Molecular docking studies, together with the crystal structures of three MTDL/TcAChE complexes, with three tacrine-valmerin hybrids allowed designing an appropriate linker containing a 1,2,3-triazole moiety whose incorporation preserved, and even increased, the original inhibitory potencies of the two selected pharmacophores toward the two targets. Most of the new derivatives exhibited nanomolar affinity for both targets, and the most potent compound of the series displayed inhibitory potencies of 9.5 nM for human acetylcholinesterase (hAChE) and 7 nM for GSK-3 alpha/beta. These novel dual MTDLs may serve as suitable leads for further development, since, in the micromolar range, they exhibited low cytotoxicity on a panel of representative human cell lines including the human neuroblastoma cell line SH-SY5Y. Moreover, these tacrine-valmerin hybrids displayed a good ability to penetrate the blood-brain barrier (BBB) without interacting with efflux pumps such as P-gp. (C) 2019 Elsevier Masson SAS.
