Identification of Advanced Reaction Products Originating from the Initial 4-Oxo-2-nonenal-cysteine Michael Adducts

4-Oxo-2-nonenal (ONE), an aldehyde originating from the peroxidation of omega 6 polyunsaturated fatty acids, preferentially reacts with the cysteine residues of protein. Despite the fact that there has been significant recent interest in the protein reactivity and biological activity of ONE, the structural basis of the ONE-cysteine adducts remain to be established. In the present study, to gain a structural insight into the sulfhydryl modification by ONE, we characterized reaction products that originated from the initial ONE-cysteine Michael adducts. N-Acetyl-L-cysteine (10 mM) was incubated with an equimolar concentration of ONE in 0.1 M phosphate buffer (pH 7.4) at 37 degrees C. Within I h of incubation, the reaction of N-acetyl-L-Cysteine with ONE resulted in the formation of two (C-2 and C-3) Michael addition products possessing a carbonyl functionality. Subsequent incubation of the reaction mixture resulted in their disappearance and concomitant formation of advanced reaction products, including a minor product III and major products IVa, IVb, and V. Product III was identified to be a thiomorpholine derivative, 4-acetyl-5-hydroxyl-6-(2-oxoheptyl)thiomorpholine-3-carboxylic acid, which might have originated from the C-2 Michael addition product. The major products were identified to be the novel 2-cyclopentenone derivatives, that is, 2-(acetylamino)-3-[(3-butyl-4-oxocyclopent-2-en-1-yl)sulfanyl] propionic acid (IVa and its isomer IVb) and 2-(acetylamino)-3-[(4-butyl-5-oxocyclopent-3-en-1-yl)sulfanyl]propionic acid (V), which might be generated through the base-catalyzed cyclization of the C-2 and C-3 Michael addition products, respectively. The furan derivative, which has been reported as the end product of the Michael adducts, was found to be formed only under acidic conditions. Thus, this study identified the novel ONE-cysteine adducts, including the most prominent 2-cyclopentenone derivatives, that originated from the initial Michael adducts.

H-1 NMR: a tool to study the fate of pollutants in the environment

In situ H-1 NMR, directly performed on biological fluids is a very powerful tool to study the fate of pollutants in the environment. The biodegradation of 2-aminobenzothiazole by Rhodococcus rhodochrous was monitored by reverse phase HPLC and by in situ H-1 NMR, methods performed directly on culture media without purification. The xenobiotic was biotransformed into a hydroxylated derivative. The chemical structure of this metabolite was determined by a long-range H-1-N-15 heteronuclear shift correlation without any previous N-15 enrichment of the compound. This approach allowed the assignment of the metabolite structure to 2-amino-6-hydroxybenzothiazole. (C) 2001 Academie des sciences/Editions scientifiques et medicates Elsevier SAS.

Improved BM212 MmpL3 Inhibitor Analogue Shows Efficacy in Acute Murine Model of Tuberculosis Infection

1,5-Diphenyl pyrroles were previously identified as a class of compounds endowed with high in vitro efficacy against M. tuberculosis. To improve the physical chemical properties and drug-like parameters of this class of compounds, a medicinal chemistry effort was undertaken. By selecting the optimal substitution patterns for the phenyl rings at N1 and C5 and by replacing the thiomorpholine moiety with a morpholine one, a new series of compounds was produced. The replacement of the sulfur with oxygen gave compounds with lower lipophilicity and improved in vitro microsomal stability. Moreover, since the parent compound of this family has been shown to target MmpL3, mycobacterial mutants resistant to two compounds have been isolated and characterized by sequencing the mmpL3 gene; all the mutants showed point mutations in this gene. The best compound identified to date was progressed to dose-response studies in an acute murine TB infection model. The resulting ED99 of 49 mg/Kg is within the range of commonly employed tuberculosis drugs, demonstrating the potential of this chemical series. The in vitro and in vivo target validation evidence presented here adds further weight to MmpL3 as a druggable target of interest for anti-tubercular drug discovery.

Copper(I) (Pseudo)Halide Complexes with Neocuproine and Aminomethylphosphines Derived from Morpholine and Thiomorpholine – In Vitro Cytotoxic and Antimicrobial Activity and the Interactions with DNA and Serum Albumins

Herein, a series of CuI or CuNCS complexes with neocuproine (2,9-dimethyl-1,10-phenanthroline: dmp) and two tris(aminomethyl)phosphines derived from morpholine (P(CH2N(CH2CH2)(2)O)(3)) or thiomorpholine (P(CH2N(CH2CH2)(2)S)(3)) were tested as cytotoxic agents in vitro towards mouse colon carcinoma (CT26) and human lung adenocarcinoma (A549). The studies showed that the complexes exhibit potential antitumor properties, displayed by IC50 values below 10m towards the tested cell lines, in the case of 4-h incubation time with the examined compounds. Moreover, a high antimicrobial activity of all the complexes was observed against Staphylococcus aureus and Candida albicans with minimal inhibitory concentrations equal to 1-2g/mL. To gain insight into the molecular mechanism of biological activity of the complexes, we investigated also their interactions with plasmid DNA (pUC18) and the human and bovine serum albumins. Gel electrophoresis experiments demonstrated that all the compounds were comparably efficient in DNA degradation process; however, luminescence quenching showed surprising dependence on the interactions strength of the used compounds with the albumins. Apart from exceptionally effective [CuI(dmp)P(CH2N(CH2CH2)(2)O)(3)], the complexes with P(CH2N(CH2CH2)(2)O)(3) quenched more strongly luminescence of bovine serum albumin, while the complexes with P(CH2N(CH2CH2)(2)S)(3) were more active in the quenching of human serum albumin luminescence.

Development and validation of a stability indicating method for S-carboxymethyl-L-cysteine and related degradation products in oral syrup formulation

A stability-indicating method for the determination of S-carboxymethyl-L-cysteine and related degradation impurities in Exputex (R) 250 mg/5 mL syrup was developed in anion-exchange liquid chromatography mode. A forced degradation study supported the method development to ensure stability indicating conditions. Aqueous solutions of the active pharmaceutical ingredient and syrup samples at different pH-values were stress-tested in different thermal, light exposure and headspace conditions. One degradation product was detected in thermal stress studies at 60 degrees C and 80 degrees C in the pH range 5.0-7.0 and was identified by mass spectrometry as 5-oxo-thiomorpholine-3-carboxylic acid (lactam of carbocysteine). A second degradation product was only generated in moderately strong oxidizing conditions (0.5% H2O2 aqueous solution) and was identified as S-carboxymethyl-L-cysteine-(R/S)-sulphoxide (carbocysteine sulphoxide). The method was developed on a Zorbax SAX column, in isocratic mode. The mobile phase consisted of 200 mM phosphate solution at pH 4.0 and acetonitrile (50:50 v/v) and UV detection was performed at a wavelength of 205 nm. The method was linear for carbocysteine (R > 0.9982) over a concentration range of 2.5-50 mu g/mL and 0.4-0.6 mg/mL. Linearity for the impurities was shown from the LOQ to 50 mu g/mL. Specificity was verified and accuracy demonstrated for the active ingredient and its degradation products in syrup samples at 3 levels around their respective specification limits. Repeatability, intermediate precision and inter-laboratory reproducibility were assessed on three commercial batches, analyzed in triplicate by two operators at both the transferring and the receiving site and demonstrated a successful method transfer to the manufacturing quality control laboratory.

Thiomorpholine transformation by the fungus Bjerkandera adusta

A screening of lignin-degrading basidial fungi that can grow in the presence of thiomorpholine derivatives (the mixture of 1,4-perhydrothiazines) has been performed. Strain Bjerkandera adusta VKM F-3477 was shown to have the maximal rate of growth in the presence of these compounds, and its capacity for thiomorpholine degradation was studied. The methods of quantitative analysis of thiomorpholine and its degradation products on the basis of thin layer chromatography and high-performance liquid chromatography were developed. It was shown that the B. adusta strain did not utilize thiomorpholine as a carbon source but transformed it into thiomorpholine sulfoxide that accumulated in the medium. Mn peroxidase produced by B. adusta in the course of thiomorpholine transformation is not directly involved in its oxidation.
