Inhibition of Leishmania infantum Trypanothione Reductase by Azole-Based Compounds: a Comparative Analysis with Its Physiological Substrate by X-ray Crystallography

Herein we report a study aimed at discovering a new class of compounds that are able to inhibit Leishmania donovani cell growth. Evaluation of an in-house library of compounds in a whole-cell screening assay highlighted 4-((1-(4-ethylphenyl)-2-methyl-5-(4-(methylthio)phenyl)-1H-pyrrol-3-yl)methyl)thiomorpholine (compound 1) as the most active. Enzymatic assays on Leishmania infantum trypanothione reductase (LiTR, belonging to the Leishmania donovani complex) shed light on both the interaction with, and the nature of inhibition by, compound 1. A molecular modeling approach based on docking studies and on the estimation of the binding free energy aided our rationalization of the biological data. Moreover, X-ray crystal structure determination of LiTR in complex with compound 1 confirmed all our results: compound 1 binds to the T(SH)2 binding site, lined by hydrophobic residues such as Trp21 and Met113, as well as residues Glu18 and Tyr110. Analysis of the structure of LiTR in complex with trypanothione shows that Glu18 and Tyr110 are also involved in substrate binding, according to a competitive inhibition mechanism.

Synthetic Route of 446-32-2, The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find hit molecules. I hope my blog about 446-32-2 is helpful to your research.

meso-Tetraphenylporphyrin-derived oxypyriporphyrin, oxypyrichlorin, and thiomorpholinochlorin, as their Ni(II) complexes

trans-Diolchlorin was prepared by nucleophilic addition of methyl-Grignard bromide to meso-tetraphenyl-2,3-dioxoporphyrin, as its free base or Ni(II) complex. The trans-configuration of the vic-diol functionality was shown by single crystal X-ray diffractometry. The nickel complex of the trans-dimethyldiol proved susceptible to Pb(IV) acetate-induced, oxidative diol cleavage, generating a meso-tetraphenylsecochlorin bismethylketone Ni(II) complex, the first example of this chromophore class. Under Bronsted-basic conditions, this bisketone cyclized via an intramolecular aldol condensation to provide a meso-tetraphenyloxypyriporphyrin. Reduction of this porphyrin analog saturated the double bond in the pyridinone moiety, generating an oxypyrichlorin. Reaction of the meso-tetraphenylsecochlorin bismethylketone Ni(II) complex with Lawesson’s reagent induced the formation of a thiomorpholinochlorin substituted with two methylene groups, the first example of any porphyrin analog containing a thiomorpholine moiety.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. 21145-77-7, you can contact me at any time and look forward to more communication.

Interaction of morpholine and thiomorpholine with molecular diiodine: X-ray crystal structure of morpholinium triiodide

The reactions between the donors morpholine (1) and thiomorpholine (2) with I-2 in low polar solvents (C6H6, CHCl3, CH2Cl2) and different donor/I-2 concentration ratios (1:1, 1:2, 1:3) yield solids of stoichiometry 1 . I-2, 1H(+)I(3)(-), 1H(+)I(5)(-), 2 . I-2, and 2H+I-3(-). Crystals suitable for X-ray structure determination have been obtained only for 1H+I-3(-). All the solids were characterized by FT-Raman and FT-IR spectroscopies in the region ofthe v(I-I) frequencies. Studies in solution have been carried out on each of the reactions between 1, 2, and N-methylmorpholine (3) with I-2. The formation constants of the 1:1 adducts of 2 and 3 determined at 20 degrees C by UV-visible spectroscopy are 8500 and 8400 dm(3) mol(-1), respectively. IR spectroscopy shows that I-2 binds the nitrogen of 1 and 2 both in axial and equatorial positions. Further FT-Raman and C-13 NMR spectroscopies support the nature of weak adducts berween 1 (2) and the molecular diiodine in solution. (C) 1997 John Wiley & Sons, Inc.

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.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.If you’re interested in learning more about 611-19-8.

Amides of non-steroidal anti-inflammatory drugs with thiomorpholine can yield hypolipidemic agents with improved anti-inflammatory activity

Novel amides of non steroidal anti-inflammatory drugs (NSAIDs), alpha-lipoic acid and indole-3-acetic acid with thiomorpholine were synthesised by a simple method and at high yields (60-92%). All the NSAID derivatives highly decreased lipidemic indices in the plasma of Triton treated hyperlipidemic rats. The most potent compound was the indomethacin derivative, which decreased total cholesterol, triglycerides and LDL cholesterol by 73%, 80% and 83%, respectively. They reduced acute inflammation equally or more than most parent acids. Hence, it could be concluded that amides of common NSAIDs with thiomorpholine acquire considerable hypolipidemic potency, while they preserve or augment their anti-inflammatory activity, thus addressing significant risk factors for atherogenesis.

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.

Conventional and Microwave-assisted Total Synthesis, Antioxidant Capacity, Biological Activity, and Molecular Docking Studies of New Hybrid Compounds

Thiomorpholine was converted to the corresponding 1,3,4-oxadiazole (4), arylidenehydrazide (5a-e), and 1,2,4-triazole (7a and, 7b) derivatives via the formation of hydrazide (3). Compounds 4 and 7 were next converted to the corresponding Mannich bases containing piperidin, beta-lactam, fluoroquinolone, piperazine, or morpholine core. Conventional and microwave-assisted methods were used for all syntheses. The effect of acid catalyst on Mannich reactions was also investigated. All the newly synthesized compounds were screened for their antimicrobial, antiglucosidase, antilipase, anti-urease, and antioxidant activities. Most exhibited good-moderate antibacterial and/or antifungal activity. Docking of some of the synthesized compounds into the active sites of lipase, alpha-glucosidase, and urease was carried out in order to predict the binding affinities and noncovalent interactions stabilizing the enzyme-ligand complexes. Docking results complemented well the experimental results on inhibitory effects of compounds. Higher binding affinities were observed for active compounds in contrary to inactive ones.

Unusual Synthesis of Triosmium Carbene Clusters by Tandem Activation of Chlorohydrocarbons and Heterocyclic Amines

Reactions of the [Os3H2(CO)(10)] cluster complex (1) with six-membered heterocyclic amines (morpholine, thiomorpholine, piperidine) and halohydrocarbons (CH2Cl2, ClHC=CHCl, CH2=CCl2) at similar to 25 degrees C have been studied. Two main types of products are formed in all studied reactions. One product is carbene cluster [Os-3(mu-H)(mu-Cl){eta(1)-C(CH3)N(CH2CH2)(2)X}(CO)(9)] (X=O, S, CH2) (3, 3 a and 3 b). Second product is cluster containing enamine ligand [Os-3(mu-H){mu-CH=CHN(C2CH2)(2)X)}(2)(CO)(10)] (X=O, S, CH2) (2, 2 a and 2 b). The carbene ligand is assembled on a cluster, from three organic molecules, thus representing the first example of carbene ligands formed in this way. Clusters with carbene ligand exist as two stable isomers (rotamers hindered towards the Os-C bond), as confirmed by NMR studies and conformational analysis. We have found that in reactions of cluster 1 with acyclic amines containing an oxygen atom in gamma-position (likely morpholine in CH2Cl2), only complexes with bridging enamine ligands are formed. Compounds 2 a, 2 b, 3 and 3 b are characterized by single-crystal X-ray diffraction.

Tedaniophorbasins A and B-Novel Fluorescent Pteridine Alkaloids Incorporating a Thiomorpholine from the Sponge Tedaniophorbas ceratosis

Two new fluorescent pteridine alkaloids, tedaniophorbasins A (1) and B (2), together with the known alkaloid N-methyltryptamine, were isolated, through application of mass directed purification, from the sponge Tedaniophorbas ceratosis collected from northern New South Wales, Australia. The structures of tedaniophorbasins A and B were deduced from the analysis of 1D/2D NMR and MS data and through application of C-13 NMR DFT calculations. Tedaniophorbasin A possesses a novel 2-imino-1,3-dimethyl-2,3,7,8-tetrahydro-1H-[1,4]thiazino[3,2-g]pteridin-4(6H)-one skeleton, while tedaniophorbasin B is its 2-oxo derivative. The compounds show significant Stokes shifts (similar to 14,000 cm(-1)) between excitation and emission wavelengths in their fluorescence spectra. The new compounds were tested for bioactivity against chloroquine-sensitive and chloroquine-resistant strains of the malaria parasite Plasmodium falciparum, breast and pancreatic cancer cell lines, and the protozoan parasite Trypanosoma brucei brucei but were inactive against all targets at 40 mu M.
