  The first synthesis and molecular docking studies of diastereomerically pure substituted 4-amino-7-hydroxyheptanoic acids

  摘要：

  Diastereoselective synthesis of 4-amino-7-hydroxyheptanoic acids 1, new GABA analogues, was performed involving reduction of C-3 functionalized 5,6-dihydro-4H-1,2-oxazines available from nitroethane. Molecular docking studies showed that amino acids of type 1 may bind to GABA transaminase, however, no inhibition was observed in the experiments with the enzyme.

  摘要：

  报道了一种通过双（氧）烯胺从容易获得的硝基化合物和硝基化合物合成 α-卤代肟醚的方法。该策略的一个关键步骤涉及双（氧）烯胺与金属（Co、Zn、Mg、Mn）卤化物的前所未有的反应，该卤化物既作为促进剂又作为卤化物（Br、I、Cl）源。各种 α-卤代肟的环状和非环状醚，包括以前无法获得的 α-碘肟的三甲基甲硅烷基醚，已经以良好到高的产率合成。

  A novel and efficient four-step procedure for the synthesis of C-3-functionalised 5,6-dihydro-4H-1,2-oxazines from nitroethane is described. It includes preparation of 3-methyl-substituted six-membered cyclic nitronates, 3-(bromomethyl)-substituted 5,6-dihydro-4H-1,2-oxazines as intermediates, and nucleophilic substitution of bromine. Total yields of the target C-3-functionalised oxazines are 15-30%

  Thirteen 2-oxazine-based small molecules were synthesized targeting 5-lipoxygenase (LOX), and acetylcholinesterase (AChE). The test revealed that the newly synthesized compounds had potent inhibition towards both 5-LOX and AChE in lower micro molar concentration. Among the tested compounds, the most active compound, 2-[(2-acetyl-6,6-dimethy1-4-phenyl-5,6-dihydro-2H-1,2-oxazin-3-yl)methyl]-1H-isoindole-1,3(2H)-dione (2a) showed inhibitory activity towards 5-LOX and AChE with an IC50 values of 1.88, and 2.5 mu M, respectively. Further, the in silico molecular docking studies revealed that the compound 2a bound to the catalytic domain of AChE strongly with a highest CDOCKER score of -1.18 kcal/mol when compared to other compounds of the same series. Additionally, 2a showed a good lipophilicity (logP = 2.66), suggesting a potential ability to penetrate the blood-brain-barrier. These initial pharmacological data revealed that the compound 2a could serve as a drug-seed in developing anti-Alzheimer's agents. (C) 2014 Elsevier Ltd. All rights reserved.
