Design, synthesis and AChE inhibitory activity of indanone and aurone derivatives
摘要:
A new series of indanone and aurone derivatives have been synthesized and tested for in vitro AChE inhibitory activity by modified Ellman method. Most of them exhibit AChE inhibitory activities superior to rivastigmine. Further, the most potent compound 1g was selected to evaluate the effect on the acquisition and memory impairment by mice step-down passive avoidance test. (C) 2008 Elsevier Masson SAS.

The unsymmetrical, achiral and chiral NCN pincer ligand precursors (3a-3d) with oxazoline and pyrazole as N donors as well as (3e) which has oxazolinyl and amino group have been synthesized in a facile manner in four steps starting from commercially available isophthalaldehyde. Direct C2 metallation of the precursors (3a-3e) with Pd(OAc)(2) in refluxing HOAc, followed by treatment with LiCl at room temperature provided convenient access to the corresponding pincer palladium(II) complexes (4a-4e). The molecular structure of complex 4e has been determined by X-ray single-crystal diffraction. The obtained Pd complexes exhibited good activities in the Suzuki reactions of aryl bromides and activated aryl chlorides with phenylboronic acid. (C) 2009 Elsevier B. V. All rights reserved.

Structural optimization of 3-hydroxy-N'-arylidenepropanehydrazonamides provided new analogs with nanomolar to subnanomolar antiplasmodial activity against asexual blood stages of Plasmodium falciparum, excellent parasite selectivity, and nanomolar activity against the earliest forms of gametocyte development. Particularly, derivatives with a 1,3-dihalo-6-trifluoromethylphenanthrene moiety showed outstanding in vivo properties and demonstrated in part curative activity in the Plasmodium berghei mouse model when administered perorally.

A new series of flavonoid derivatives have been designed, synthesized and evaluated as potent AChE inhibitors. Most of them showed more potent inhibitory activities to AChE than rivastigmine. The most potent inhibitor isoflavone derivative 10d inhibit AChE with a IC50 of 4 nM and showed high BChE/AChE inhibition ratio (4575-fold), superior to donepezil (IC50 = 12 nM, 389-fold). Molecular docking studies were also performed to explore the detailed interaction with AChE. (C) 2009 Elsevier Ltd. All rights reserved.
