The formal [3+2] cycloadditions of complexes 3 with different alkynes including diynes and enynes performed in donor solvents such as pyridine or acetonitrile afforded highly substituted 5-(dialkylamino)-3-ethoxycyclopentadienes 7, generally in medium to excellent yields (25 examples with yields of 60-95% and 7 examples with yields of 18-53%). The steric and electronic effects of the substituents on the carbene complexes and the incorporated alkynes on the regio- and stereo selectivity of the ring-forming reaction have been elaborated. An interesting 1,5- or, more likely, 1,2-migration of the dimethylamino group was observed for 5-(dimethylamino)-3-ethoxycyclopentadienes with trimethylsilyl and jPr substituents at C-5. Attempted asymmetric syntheses of cyclopentadienes 7 from complexes 3 with chiral amino groups or substituents were only moderately successful. At a center of chirality in the secondary amino group, complexes of type 3 gave compounds 7 with diastereomeric excesses of, at best, 59% in yields of 54%, and with a stereogenic center in the substituent R-1 attached to the vinyl group of 3, diastereomeric excesses as high as 94% could be achieved, but with poor chemical yields (21%). In general, cyclopentenones 21 could be easily obtained from the cyclopentadienes 7 under acidic conditions in very good yields (4 examples with yields of 81-98%, 1 example with an overall yield of 50% from complex 3). Intramolecular aldol reactions of dicarbonyl compounds generated by hydrolysis of cyclopentadienes 7 with acetal-protected aldehyde or ketone carbonyl groups in either the 5-substituent R-1 or the N-substituent R-2 led to the bicyclic compounds 22 and 23. The dimethylamino group in cyclopentenones 21 could be either eliminated or transformed into other functional groups via the quaternary ammonium salts 24. The elimination product, cyclopentadienone 27 can undergo dimerization either by a formal [4+2] or [2+2] cycloaddition. Cyclopentenone 21naaa with a bromovinyl-terminated side chain undergoes an intramolecular Heck reaction to form 5-methyl-4,6-dimethylenebicyclo[3.3.0]oct-1-en-3one (32) (37% yield).

Spreading depression (SD) resembles a concerted, massive neuronal/glial depolarization propagating within the gray matter. Being associated with cerebropathology, such as cerebral ischemia or hemorrhage, epileptic seizures, and migraine, it is well studied in cortex and hippocampus. We have now analyzed the susceptibility of rat brain stem to hypoxia-induced spreading depression-like depolarization (HSD), which could critically interfere with cardiorespiratory control. In rat brain stem slices, severe hypoxia (oxygen withdrawal) triggered HSD within minutes. The sudden extracellular DC potential shift of approximately -20 mV showed the typical profile known from other brain regions and was accompanied by an intrinsic optical signal (IOS). Spatiotemporal IOS analysis revealed that in infant brain stem, HSD was preferably ignited within the spinal trigeminal nucleus and then mostly spread out medially, invading the hypoglossal nucleus, the nucleus of the solitary tract (NTS), and the ventral respiratory group (VRG). The neuronal hypoxic depolarizations underlying the generation of HSD were massive, but incomplete. The propagation velocity of HSD and the associated extracellular K+ rise were also less marked than in other brain regions. In adult brain stem, HSD was mostly confined to the NTS and its occurrence was facilitated by hypotonic solutions, but not by glial poisoning or block of GABAergic and glycinergic synapses. In conclusion, brain stem tissue reliably generates propagating HSD episodes, which may be of interest for basilar-type migraine and brain stem infarcts. The preferred occurrence of HSD in the infant brain stem and its propagation into the VRG may be of importance for neonatal brain stem pathology such as sudden infant death syndrome."],["dc.description.sponsorship","Deutsche Forschungsgemeinschaft"],["dc.identifier.doi","10.1152/jn.91260.2008"],["dc.identifier.isi","000265398100023"],["dc.identifier.pmid","19261708"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/16886"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Amer Physiological Soc"],["dc.relation.issn","0022-3077"],["dc.title","Infant Brain Stem Is Prone to the Generation of Spreading Depression During Severe Hypoxia"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

In a RTT mouse model (methyl-CpG-binding protein 2-deficient mice; Mecp2(-/y)) we recently discovered an enhanced hippocampal susceptibility to hypoxia and hypoxia-induced spreading depression (HSD). In the present study we investigated whether this also applies to infant Mecp2(-/y) brain stem, which could become life-threatening due to failure of cardiorespiratory control. HSD most reliably occurred in the nucleus of the solitary tract (NTS) and the spinal trigeminal nucleus (Sp5). HSD susceptibility of the Mecp2(-/y) NTS and Sp5 was increased on 8 mM K(+)-mediated conditioning. 5-HT(1A) receptor stimulation with 8-hydroxy-2-(di-propylamino)tetralin (8-OH-DPAT) postponed HSD by up to 40%, mediating genotype-independent protection. The deleterious impact of HSD on in vitro respiration became obvious in rhythmically active slices, where HSD propagation into the pre-Bötzinger complex (pre-BötC) immediately arrested the respiratory rhythm. Compared with wild-type, the Mecp2(-/y) pre-BötC was invaded less frequently by HSD, but if so, HSD occurred earlier. On reoxygenation, in vitro rhythms reappeared with increased frequency, which was less pronounced in Mecp2(-/y) slices. 8-OH-DPAT increased respiratory frequency but failed to postpone HSD in the pre-BötC. Repetitive hypoxia facilitated posthypoxic recovery only if HSD occurred. In 57% of Mecp2(-/y) slices, however, HSD spared the pre-BötC. Although this occasionally promoted residual hypoxic respiratory activity (\"gasping\"), it also prolonged the posthypoxic recovery, and thus the absence of central inspiratory drive, which in vivo would lengthen respiratory arrest. In view of the breathing disorders in RTTs, the increased hypoxia susceptibility of MeCP2-deficient brain stem potentially contributes to life-threatening disturbances of cardiorespiratory control."],["dc.identifier.doi","10.1152/jn.00822.2010"],["dc.identifier.pmid","21471397"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/15858"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.eissn","1522-1598"],["dc.title","Altered responses of MeCP2-deficient mouse brain stem to severe hypoxia"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]

Especially mitochondria modulate the cytosolic redox status by oxidizing NADH and FADH(2) and generating reactive oxygen species (ROS). Whereas cellular NADH and FAD levels are reliably detectable as autofluorescence, quantifying cellular ROS production is more demanding, because the various redox-sensitive dyes share major disadvantages including irreversible oxidation, autooxidation and photosensitivity. As an alternative, we took advantage of a genetically engineered redox-sensitive green fluorescent protein (roGFP1), carefully evaluated its response properties, and succeeded to monitor ROS dynamics in cultured rat hippocampal neurons and organotypic slices. The ratiometric properties and reversible oxidation/reduction of roGFP1 enable reliable, semi-quantitative analyses of cytosolic ROS levels and redox status. Cytosolically expressed roGFP1 readily responded to hydrogen peroxide, superoxide and hydroxyl radicals, and was only negligibly affected by intracellular pH or Cl(-) content. Furthermore, roGFP1 was well suited for two-photon excitation, reliably detected changes in endogenous ROS production during impaired mitochondrial respiration or neuronal stimulation, and was even capable of visualizing perimitochondrial ROS microdomains. Modulation of cellular scavenging systems confirmed the functional integration of roGFP1 into the cellular ROS and redox balance. We conclude that roGFP1 is well suited for dynamic, compartment specific, subcellular analyses even in complex neuronal networks. The ability to correlate dynamic changes in cellular ROS levels with mitochondrial metabolism and neuronal network activity is a promising step towards a detailed mechanistic understanding of redox- and ROS-mediated signaling in normal and diseased brain function."],["dc.identifier.doi","10.1016/j.neuroimage.2010.11.031"],["dc.identifier.pmid","21081169"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/6124"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/15859"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.relation.eissn","1095-9572"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Dynamic, semi-quantitative imaging of intracellular ROS levels and redox status in rat hippocampal neurons"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]

So far, its respiratory activity has been analyzed predominantly by electrophysiological approaches. Recent advances in fluorescence imaging now allow for the visualization of neuronal population activity in rhythmogenic networks. In the respiratory network, voltage-sensitive dyes have been used mainly, so far, but their low sensitivity prevents an analysis of activity patterns of single neurons during rhythmogenesis. We now have succeeded in using more sensitive Ca2+ imaging to study respiratory neurons in rhythmically active brain stem slices of neonatal rats. For the visualization of neuronal activity, fluo-3 was suited best in terms of neuronal specificity, minimized background fluorescence, and response magnitude. The tissue penetration of fluo-3 was improved by hyperosmolar treatment (100 mM mannitol) during dye loading. Rhythmic population activity was imaged with single-cell resolution using a sensitive charge-coupled device camera and a x20 objective, and it was correlated with extracellularly recorded mass activity of the contralateral PBC. Correlated optical neuronal activity was obvious online in 29% of slices. Rhythmic neurons located deeper became detectable during offline image processing. Based on their activity patterns, 74% of rhythmic neurons were classified as inspiratory and 26% as expiratory neurons.
