  Regulation of the Escherichia coli AtoSC two component system by synthetic biologically active 5;7;8-trimethyl-1;4-benzoxazine analogues

  摘要：

  The Escherichia coli AtoSC two component system; upon acetoacetate induction; regulates the expression of the atoDAEB operon; through His -> Asp phopshotransfer; thus modulating important cellular processes. In this report the effect of seven 5,7,8-trimethyl-1,4-benzoxazine derivatives on the regulation of the E. coli AtoSC system was studied. The new compounds were tested for their effectiveness on the expression of the atoC and the regulated atoDAEB operon. The non-substituted 5,7,8-trimethyl-1,4-benzoxazine (4a), was the most potent inducer on atoC transcription; resulting in accumulation of AtoC protein. The induction of atoC by 4a was specific; since no effect was observed on the other genes of the system (atoS and atoDAEB). Moreover; compound 4a was shown to significantly up-regulate the in vitro kinase activity of the histidine kinase AtoS without altering the protein levels in the cell. Interestingly; this compound appeared to modulate the acetoacetate-mediated induction of the atoDAEB promoter by the AtoSC system. These data provide the first evidence for a differential modulator role of 5,7,8-trimethyl-1,4-benzoxazine; on the AtoSC two component system mediated signaling. (C) 2011 Elsevier Ltd.

  5,7,8-Trimethyl-benzopyran and 5,7,8-Trimethyl-1,4-benzoxazine Aminoamide Derivatives as Novel Antiarrhythmics against Ischemia−Reperfusion Injury

  摘要：

  6-Hydroxy-5,7,8-trimethyl-benzopyran derivatives and 5,7,8-trimethyl-1,4-benzoxazine analogues substituted by the lidocaine pharmacophore aminoamide functionality at C4 of N4, respectively, were synthesized and evaluated against arrhythmias associated with ischemia-reperfusion injury. The antiarrhythmic effect of substitutents at positions C2 and C6 was examined. Six out of the 11 new derivatives, exhibited arrhythmia scores 1.0-1.3 versus the control (4.5 +/- 1.2), which was also reflected to the % premature beats (0.5-3.9), control (13.7 +/- 3.6). Selected compounds were further studied by a conventional microelectrode method. 2-diethylamino-1-(5,7,8-trimethyl-2-phenyl-2,3-dihydro-benzo[1,4]oxazin-4-yl)-ethanotic (50) and the trolox-inspired 4-(2-diethylamino-acetyl)-2,5,7,8-tetramethyl-3.4-dihydro-2H-benzo[1,4]oxazine-2-carboxylic acid ethyl ester (62) Suppress reperfusion arrhythmias and reduce malondialdehyde (MDA) content, leading to a fast recovery of the heart after ischemia-reperfusion. They exhibit combined class IB and class III antiarrhythmic properties, which constitutes them as promising compounds for further studies because, due to their multichannel "amiodarone like" effect, less proarrhythmic complications can be expected.

  The Woodward–Hoffmann rules predict whether concerted pericyclic reactions are allowed or forbidden based on the number of electrons involved and whether the cyclic orbital overlap involves suprafacial or antarafacial orbital overlap. Pseudopericyclic reactions constitute a third class of reactions in which orthogonal orbitals make them orbital symmetry allowed, regardless of the number of electrons

  Woodward-Hoffmann规则根据所涉及的电子数以及环状轨道重叠是否涉及表面或反面轨道重叠来预测是否允许进行一致的周环反应。伪周环反应构成第三类反应，其中正交轨道使它们成为轨道对称性，而与反应中涉及的电子数无关。基于最近关于八中心酯重排的报道，预言也将允许亚胺的等电子八中心重排。现在，我们报告说发生了这些重排，实际上，在三氯乙酰亚胺基酰基环己二酮中，至少在一种情况下，以八中心重排略胜于众所周知的六中心超人重排，
