It contains many common chemicals found in the Aldrich Handbook of Fine Chemicals. To create the Aldrich Raman Condensed Phase Library, 14,033 compounds found in the Aldrich Collection of FT-IR Spectra Edition II Library were excited with an Nd:YVO4 laser (1064 nm) using laser powers between 400 - 600 mW, measured at the sample. A Thermo FT-Raman spectrometer (with a Ge detector) was used to collect the Raman spectra. The spectra were saved in Raman Shift format.

The Impact of D-Cycloserine and Sarcosine on in Vivo Frontal Neural
Yao et al. BMC Psychiatry (2019) 19:314 https://doi.org/10.1186/s12888-019-2306-1 RESEARCH ARTICLE Open Access The impact of D-cycloserine and sarcosine on in vivo frontal neural activity in a schizophrenia-like model Lulu Yao1, Zongliang Wang1, Di Deng1, Rongzhen Yan1, Jun Ju1 and Qiang Zhou1,2* Abstract Background: N-methyl-D-aspartate receptor (NMDAR) hypofunction has been proposed to underlie the pathogenesis of schizophrenia. Specifically, reduced function of NMDARs leads to altered balance between excitation and inhibition which further drives neural network malfunctions. Clinical studies suggested that NMDAR modulators (glycine, D-serine, D-cycloserine and glycine transporter inhibitors) may be beneficial in treating schizophrenia patients. Preclinical evidence also suggested that these NMDAR modulators may enhance synaptic NMDAR function and synaptic plasticity in brain slices. However, an important issue that has not been addressed is whether these NMDAR modulators modulate neural activity/spiking in vivo. Methods: By using in vivo calcium imaging and single unit recording, we tested the effect of D-cycloserine, sarcosine (glycine transporter 1 inhibitor) and glycine, on schizophrenia-like model mice. Results: In vivo neural activity is significantly higher in the schizophrenia-like model mice, compared to control mice. D-cycloserine and sarcosine showed no significant effect on neural activity in the schizophrenia-like model mice. Glycine induced a large reduction in movement in home cage and reduced in vivo brain activity in control mice which prevented further analysis of its effect in schizophrenia-like model mice. Conclusions: We conclude that there is no significant impact of the tested NMDAR modulators on neural spiking in the schizophrenia-like model mice. -

Ketene Reactions. I. the Addition of Acid Chlorides
KETENE REACTIONS. I. THE ADDITION OF ACID CHLORIDES TO DIMETHYLKETENE. II. THE CYCLOADDITION OF KETENES TO CARBONYL COMPOUNDS APPROVED: Graduate Committee: Major Professor Committee Member.rr^- Committee Member Committee Member Director of the Department of Chemistry Dean' of the Graduate School Smith, Larry, Ketene Reactions. I. The Addition of Acid Chlorides to DimethyIketene. II. The Cycloaddition of Ketenes to Carbonvl Compounds. Doctor of Philosophy (Chemistry), December, 1970, 63 pp., 3 tables, bibliography, 62 titles. Part I describes the addition of several acid chlorides to dimethylketene. The resulting 3-ketoacid chlorides were isolated and characterized. The reactivities of acid chlorides were found to parallel the parent acid pKa's. A reactivity order of ketenes toward acid chlorides was established. Dimethylketene is more reactive than ketene which is more reactive than diphenylketene. Attempts to effect the addition of an acid halide to a ketene produced by in situ dehydro- halogenation yielded a-halovinyl esters. The addition of acid chlorides to ketenes was concluded to be an ionic process dependent upon the nucleophilic character of the ketene oc- carbon and the polarity of the carbon-chlorine bond in the acid chloride. Part II describes the cycloaddition of several aldo- ketenes to chloral. The ketenes were generated in situ by dehydrohalogenation and dehalogenation of appropriately substituted acyl halides. Both cis- and trans-4-trichloro- Miyl-2-oxetanones are produced in the cycloadditions with the sterically hindered cis isomer predominating. Isomer distributions were determined by vpc or nmr analysis of the reaction solutions. Production of the ketenes by dehalo- genation resulted in enhanced reactivity of the carbonyl compounds.
