Metabolomics is considered an effective approach for understanding metabolic responses in complex biological systems. Accordingly, it has attracted increasing attention for biomarker discovery, especially in cancer. In this study, we used a non-invasive method to evaluate four urine metabolite biomarker candidates?o-phosphoethanolamine, 3-amio-2-piperidone, uridine and 5-hydroxyindoleactic acid?for their potential as bladder cancer diagnostic biomarkers. To analyze these targeted amine- and phenol-containing metabolites, we used differential 12C2-/13C2-dansylation labeling coupled with liquid chromatography/tandem mass spectrometry, which has previously been demonstrated to exhibit high sensitivity and reproducibility. Specifically, we used ultra-performance liquid chromatography (UPLC) coupled with high-resolution Fourier transform ion-cyclotron resonance MS system (LC-FT/MS) and an ion trap MS with MRM function (LC-HCT/MS) for targeted quantification. The urinary metabolites of interest were well separated and quantified using this approach. To apply this approach to clinical urine specimens, we spiked samples with 13C2-dansylatedsynthetic compounds, which served as standards for targeted quantification of 12C2-dansylated urinary endogenous metabolites using LC-FT/MS as well as LC-HCT/MS with MRM mode. These analyses revealed significant differences in two of the four metabolites of interest?o-phosphoethanolamine and uridine?between bladder cancer and non-cancer groups. O-phosphoethanolamine was the most promising single biomarker, with an area-under-the-curve (AUC) value of 0.709 for bladder cancer diagnosis. Diagnostic performance was improved by combining uridine and o-phosphoethanolamine in a marker panel, yielding an AUC value of 0.726. This study confirmed discovery-phase features of the urine metabolome of bladder cancer patients and verified their importance for further study.

Sweat has recently gained popularity as clinical sample in metabolomics analysis as it is a non-invasive biofluid the composition of which could be modified by certain pathologies, as is the case with cystic fibrosis that increases chloride levels in sweat. However, the whole composition of sweat is still unknown and there is a lack of analytical strategies for sweat analysis. The aim of the present study was to develop and validate a method for metabolomic analysis of human sweat by gas chromatography-time of flight/mass spectrometry (GC-TOF/MS) in high resolution mode. Thus, different sample preparation strategies were compared to check their effect on the profile of sweat metabolites. Sixty-six compounds were tentatively identified by the obtained MS information. Amino acids, dicarboxylic acids and other interesting metabolites such as myo-inositol and urocanic acid were identified. Among the tested protocols, methyoxiamination plus silylation after deproteinization was the most suited option to obtain a representative snapshot of sweat metabolome. The intra-day repeatability of the method ranged from 0.60 to 16.99% and the inter-day repeatability from 2.75 to 31.25%. As most of the identified metabolites are involved in key biochemical pathways, this study opens new possibilities to the use of sweat as a source of metabolite biomarkers of specific disorders.

One-pot parallel synthesis approach to secondary amines based on the reductive amination of ketones

A combination of a condensation mixture [a Lewis acid, Ti(Oi-Pr) 4, and a water scavenger, 1-(trimethylsilyl)-2-pyrrolidinone] and a simple reductant (NaBH4) provides an efficient one-pot approach to parallel synthesis of secondary amines by the reductive amination of ketones. The approach demonstrated its applicability to a variety of substrates with different degree of hindrance of an amino or a carbonyl group affording products in moderate to high yields.

Preparation of D-alpha-aminolactams by L-enantioselective degradation of alpha-aminolactam mediated by Mesorhizobium sp. L88

By the screening of microorganisms that can assimilate alpha-amino-epsilon-caprolactam (ACL) as a sole source of carbon and nitrogen from 115 soil samples, two microorganisms that can hydrolyze ACL l-enantioselectively and degrade further have been isolated and identified as Mesorhizobium sp. L88 and Aneurinibacillus migulanus L168. The culture and reaction conditions of Mesorhizobium sp. L88 were optimized to apply the intact cells to the preparation of enantiomerically pure d-alpha-aminolactams. Under the optimized conditions, d-alpha-aminolactams with a five- to an eight-membered ring were prepared with an enantiomeric excess of >99.8%. Ring-opened alpha-amino- N’-alkylamides, lysine amide, ornithine amide, epsilon-caprolactam, and delta-valerolactam were not accepted as substrates.

Unusually Large 13C NMR Chemical Shift Differences between Neutral and Protonated Glycocyamidines. New Insights on Previously Reported Chemical Shift Assignments and Chemical Properties

Unusually large 13C chemical shift differences are observed between neutral and protonated glycocyamidine (2-aminoimidazolinone) derivatives. Upon protonation, the guanidine (N-C=N) and carbonyl (C=O) carbons undergo an upfield shift of approximately 12 and 17 ppm, respectively, relative to the neutral species. For neutral glycocyamidine derivatives, the 13C chemical shifts for the carbonyl carbon reside above 190 ppm. In the protonated form, the carbonyl resonances are in the mid to lower 170s. These values are indicative of the protonation state of the glycocyamidine moiety. The present study serves as a useful reference in assisting the characterization of future glycocyamidine-based natural products and derivatives.
