Thiazolidine Derivatives Attenuate Carrageenan-Induced Inflammatory Pain in Mice

Background: Peripheral inflammation leads to the development of persistent thermal hyperalgesia and mechanical allodynia associated with increased expression of interleukin-1 beta (IL-1 beta) in the spinal cord. The aim of the present study was to investigate the effects of thiazolidine derivatives, 1b ([2-(2-hydroxyphenyl)-1,3-thiazolidin-4-yl](morpholin-4-yl) methanone) and 1d (2-hydroxy-4-{[2-(2-hydroxyphenyl)-1,3-thiazolidine-4-carbonyl] amino}benzoic acid), on thermal hyperalgesia, mechanical allodynia and on IL-1 beta expression during carrageenan-induced inflammation in the spinal cord in mice. Inflammatory pain was induced by injecting 1% carrageenan into the right hind paw of the mice. Methods: The animals were administered thiazolidine derivatives, 1b and 1d (1 mg/kg, 3 mg/kg, or 10 mg/kg), intraperitoneally 30 minutes before carrageenan administration. The animals’ behavior was evaluated by measuring thermal hyperalgesia, mechanical allodynia, and motor coordination. The IL-1 beta expression was measured by enzyme-linked immunosorbent assay. Acute and sub-acute toxicity studies were conducted to evaluate the toxicity profile of compounds. Results: Treatment with the thiazolidine derivative, 1b and 1d, attenuated carrageenan-induced thermal hyperalgesia and mechanical allodynia at doses of 1 mg/kg, 3 mg/kg, and 10 mg/kg. No motor coordination deficits were observed in animals. The compounds also reduced IL-1 beta expression in the spinal cord of mice. Acute and sub-acute toxicity studies revealed that both compounds were safe. Conclusion: The compounds exhibit promising activity against inflammatory pain due to their ability to produce anti-hyperalgesic and anti-allodynic effects and to inhibit IL-1 beta expression in the spinal cord.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 29681-57-0, you can contact me at any time and look forward to more communication. Recommanded Product: 29681-57-0.

Thiazole-Bearing 4-Thiazolidinones as New Anticonvulsant Agents

Here, we describe the synthesis and anticonvulsant activity of thiazole-bearing hybrids based on 2-imino-4-thiazolidinone and 2,4-dioxothiazolidine-5-carboxylic acid cores. The structure of target compounds was based on the following: (i) A combination of two thiazole cores; (ii) similarity to ralitolin’s structure; (iii) the compliance with structural requirements for the new anticonvulsants. Target compounds were synthesized via known approaches based on Knoenavegel reaction, alkylation reaction, and one-pot three-component reaction. Anticonvulsant properties of compounds were evaluated in two different models-pentylenetetrazole-induced seizures and maximal electroshock seizure tests. Among the tested compounds 5Z-(3-nitrobenzylidene)-2-(thiazol-2-ylimino)-thiazolidin-4-one Ib, 2-[2,4-dioxo-5-(thiazol-2- ylcarbamoylmethyl)-thiazolidin-3-yl]-N-(2-trifluoromethylphenyl)acetamide IId and (2,4-dioxo-5- (thiazol-2-ylcarbamoylmethylene)-thiazolidin-3-yl)acetic acid ethyl ester IIj showed excellent anticonvulsant activity in both models. The directions of compounds modification based on SAR aspects were discussed. The results of the study provide a basis for further study of the anticonvulsant properties of selected thiazole-thiazolidinones.

Crystal structures of two (Z)-2-(4-oxo-1,3-thiazolidin-2-ylidene) acetamides

The crystal structures of two (oxothiazolidin-2-ylidene) acetamides, namely (Z)-2-[2-(morpholin-4-yl)-2-oxoethylidene] thiazolidin-4-one, C9H12N2O3S, (I), and (Z)-N-(4-methoxyphenyl)-2-(4-oxothiazolidin-2-ylidene) acetamide, C12H12N2O3S, (II), are described and compared with a related structure. The Z conformation was observed for both the compounds. In (I), the morpholin-4-yl ring has a chair conformation and its mean plane is inclined to the thiazolidine ring mean plane by 37.12 (12)degrees. In (II), the benzene ring is inclined to the mean plane of the thiazolidine ring by 20.34 (14) degrees. In the crystal of (I), molecules are linked by N-H center dot center dot center dot O hydrogen bonds, forming C(6) chains along the b-axis direction. The edge-to-edge arrangement of the molecules results in short C-H center dot center dot center dot O and C-H center dot center dot center dot S interactions, which consolidate the chain into a ribbon-like structure. In the crystal of (II), two N-H center dot center dot center dot O hydrogen bonds result in the formation of C(8) chains along the b-axis direction and C(6) chains along the c-axis direction. The combination of these interactions leads to the formation of layers parallel to the bc plane, enclosing R-4(4) (28) rings involving four molecules.

Preclinical efficacy of a gastro-sparing novel thiazolidin-4-one in alleviating secondary lesions of polyarthritis: A multi-parametric approach

The promising role of thiazolidin-4-ones (TZOs) against inflammatory conditions has been reported. From our lab, one of the TZO derivatives, compound 4C, exerted anti-inflammatory potential via inhibition of locally released cytokines and prostaglandin. In continuance, a detailed study was undertaken for the preclinical profiling of this promising TZO derivative against polyarthritis in rats, along with assessment of risk associated with the treatment. Male Sprague-Dawley rats were used for the adjuvant-induced arthritis (AIA) model. Based on the development of secondary lesion, the animals were randomized into different treatment groups. To establish the efficacy of the test compound, parameters such as inflammation, pain, disease progression, cytokines and prostaglandin (PG)-E-2 levels and complete blood cell profile were recorded along with radiological and histological examinations of joints. The study also focused on evaluating the side effect of test compound on gastric, liver, renal, blood and cardiovascular components. Compound 4C exerted promising therapeutic effect against secondary lesions in polyarthritis in rats. It limited the progression of chronic inflammation and associated pain in rats. Modulation of cytokine signalling and arachidonate metabolism by 4C was evident from inhibition of interleukin (IL)-6, tumor necrosis factor (TNF)-alpha and PGE(2) generation in AIA rats. Comparatively, compound 4C was safer than diclofenac to cause gastric, liver, renal, blood and cardiovascular toxicities. These finding supports the efficacy and safety profile of 4C, a TZO derivative in limiting the progression of arthritis when administered orally. (C) 2016 Elsevier B.V. All rights reserved.

Synthesis, computational studies and enzyme inhibitory kinetics of substituted methyl[2-(4-dimethylamino-benzylidene)-hydrazono)-4-oxo- thiazolidin-5-ylidene] acetates as mushroom tyrosinase inhibitors

The present article describes the synthesis and enzyme inhibitory kinetics of methyl[ 2-(arylmethylenehydrazono)-4-oxo-thiazolidin-5-ylidene] acetates 5a-j as mushroom tyrosinase inhibitors. The title compounds were synthesized via cyclocondensation of thiosemicarbazones 3a-j with dimethyl but-2-ynedioate (DMAD) 4 in good yields under solvent-free conditions. The synthesized compounds were evaluated for their potential to inhibit the activity of mushroom tyrosinase. It was unveiled that compounds 5i showed excellent enzyme inhibitory activity with IC50 3.17 mu M while IC50 of standard kojic acid is 15.91 mu M. The presence of heterocyclic pyridine ring in compound 5i play important role in enzyme inhibitory activity as rest of the functional groups are common in all synthesized compounds. The enzyme inhibitory kinetics of the most potent derivative 5i determined by Lineweaver-Burk plots and Dixon plots showed that it is non-competitive inhibitor with Ki value 1.5 mu M. It was further investigated that the wet lab results are in good agreement with the computational results. The molecular docking of the synthesized compounds was performed against tyrosinase protein (PDBID 2Y9X) to delineate ligand-protein interactions at molecular level. The docking results showed that the major interacting residues are His244, His85, His263, Val 283, His 296, Asn260, Val248, His260, His261 and Phe264 which are located in active binding site of the protein. The molecular modeling demonstrates that the oxygen atom of the compound 5i coordinated with the key residues in the active site of mushroom tyrosinase contribute significantly against inhibitory ability and diminishing the human melanin synthesis. These results evident that compound 5i is a lead structure in developing most potent mushroom tyrosinase inhibitors. (C) 2017 Elsevier Ltd. All rights reserved.

Magnetized inorganic-bioorganic nanohybrid [nano Fe3O4-SiO2@Glu-Cu (II)]: A novel nanostructure for the efficient solvent-free synthesis of thiazolidin-2-imines

In this research, a solvent-free four-component one-pot reaction of phenyl isothiocyanate, phenylacetylene, various kinds of aldehydes, and amines was interpreted to obtain the desired five-membered heterocycles named thiazolidin-2-imines. The promotor of this transformation is a novel magnetite-based multilayered inorganic-bioorganic nanohybrid prepared via embedding glutamic acid on the magnetized silica followed by anchoring Cu (II) [nano Fe3O4-SiO2@Glu-Cu (II)]. The newly synthesized nanostructure is characterized through Fourier-transform infrared (FT-IR), field-emission scanning electron microscopy (FESEM), energy dispersive X-ray analysis (EDAX), transmission electron microscopy (TEM), X-ray fluorescence (XRF), thermogravimetric analysis or derivative thermogravimetric (TGA/DTG), vibrating sample magnetometer (VSM), X-ray photoelectron spectroscopy (XPS), and Brunauer-Emmett-Teller (BET) techniques. This protocol is a straightforward one-step procedure to obtain thiazolidin-2-imines without requirement to propargylamines or imines as substrates. In addition, easy work-up procedure, high yields of products, absence of organic solvents in the reaction media, recovery and reusability of nano Fe3O4-SiO2@Glu-Cu(II) to promote the reaction at least for three runs without activity lost, simple separation of the catalyst from reaction mixture via an external magnet, and regioselectivity of the method are some highlighted aspects of the approach.

Synthesis and Antifungal Activity against Fusarium oxysporum of Some Brassinin Analogs Derived from L-tryptophan: A DFT/B3LYP Study on the Reaction Mechanism

An efficient methodology to obtain novel antifungal analogs of brassinin 1 is described. Starting from L-tryptophan 2, N, N’-dialkylthiourea 4, 4-[(1H-indol-3-yl) methylene]-2-sulfanylidene-1,3-thiazolidin-5-one 5 and alkyl (2S)-3-(1H-indol-3-yl)-2-{[(alkylsulfanyl) carbonothioyl] amino} propanoate 6 type compounds were obtained as main products in different ratios depending on the reaction conditions via a tandem dithiocarbamate formation and Michael addition reaction. In order to understand the dependence of the reaction conditions on the mechanism pathway, a DFT/B3LYP study was performed. The results suggested the existence of competitive mechanistic routes which involve the presence of an ionic dithiocarbamate intermediate 9. Antifungal activities of all products were then evaluated against Fusarium oxysporum through mycelial growth inhibition using a microscale amended-medium assay. IC50 values were thus determined for each compound. These results showed that 6-related compounds can be considered as promissory antifungal agents.
