  Structure-based design, synthesis and biological evaluation of novel β-secretase inhibitors containing a pyrazole or thiazole moiety as the P3 ligand

  摘要：

  We describe structure-based design, synthesis, and biological evaluation of a series of novel inhibitors bearing a pyrazole (compounds 3a-h) or a thiazole moiety (compounds 4a-e) as the P3 ligand. We have also explored Boc-beta-amino-L-alanine as a novel P2 ligand. A number of inhibitors have displayed b-secretase inhibitory potency. Inhibitor 4c has shown potent BACE1 inhibitory activity, K-i = 0.25 nM, cellular EC50 of 194 nM, and displayed good selectivity over BACE2. A model of 4c was created based upon the X-ray structure of 2-bound beta-secretase which revealed critical interactions in the active site. (C) 2014 Elsevier Ltd. All rights reserved.

• Synthesis of N- and C-azolyl-substituted pyrazolo[1,5-a]pyrimidines by recyclization of pyrimidinium salts

  We studied the reaction of 2-(ethoxycarbonyl)methyl-1,4,6-trimethylpyrimidinium iodide with hydrazides of N-azolyl- and D-pyrazolylsubstituted carboxylic acids, which were synthesized by reacting the respective esters with hydrazine hydrate. This reaction was shown to result in recyclization and formation of ethyl 2-(pyrazolylalkyl)- and 2-(azolylalkyl)-5,7-dimethylpyrazolo[1,5-a]pyrimidine-3-carboxylates. Besides pyrazolopyrimidines, the separation of reaction mixture provided in some cases also another recyclization product, 2-hydroxy-5,7-dimethylpyrazolo[1,5-a]pyrimidine.
• Synthesis of α-methyl-β-(3-methylpyrazol-1-yl)-and α-methyl-β-(5-methylpyrazol-1-yl)propionic acids and their esterification with vinyl acetate

  alpha-Methyl-beta-(3-methylpyrazol-1-yl)- and alpha-methyl-beta-(5-methylpyrazol-1-yl)propionic acids were synthesized by reaction of 3(5)-methylpyrazole with methyl methacrylate, followed by separation of the resulting isomeric esters and their hydrolysis. Esterification of the title acids was performed via vinyl exchange reaction with vinyl acetate in the catalytic system mercury acetate-trifluoroacetic acid.
