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.

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.

Synthesis of novel indole derivatives as promising DNA-binding agents and evaluation of antitumor and antitopoisomerase I activities

Molecules bearing indole nucleus present diverse biological properties such as antitumor and antiinflammatory activities that can be associated both to DNA and protein interactions. This study focused on the synthesis of new indole derivatives with thiazolidines and imidazolidine rings condensed as side chains as well as the evaluation of their ability to interact with the DNA and antitumor and topoisomerase inhibition activities. All derivatives were successfully synthesized and their structures were elucidated by mass spectrometry (MS), infrared (IR), spectroscopy H-1 NMR,C-13 NMR, COSY H-1-H-1 and HSQC H-1-C-13. The antitumor activity was evaluated against different cancer cell lines using the antiproliferative MTT assay. DNA binding ability was analyzed by absorption spectroscopy and fluorescence technique using ethidium bromide (EB) as a fluorescent probe. Changes were observed in spectroscopic properties of the compounds after interacting with ctDNA (calf thymus DNA), with hypochromic and hyperchromic effects, besides blue or red shifts in the maxima of spectra. The indole derivative 5-(1H-Indo1-3-ylmethylene)-thiazolidin-2,4-dione (4c) presented the best results in antitumor assay against the breast line tested (T47D), with IC50 value lower than the positive control, doxorubicin (1.93 and 4.61 mu M, respectively). On the other hand, the compound 3-amino-5-(1H-indo1-3ylmethylene)-2-thioxo-thiazolidin-4-one (4a) was active against leukemia cell lines (HL60 and K562) with the high value of the DNA binding constant, Kb of 5.69 x 10(4). However, this compound (4a) did not inhibit the topoisomerase-I activity evaluated by relaxation assay. These results show that the indole nucleus contribute to the incorporation of molecules into the DNA. Moreover, it was highlighted that basic side chains, such as thiazolidines and imidazolidines, and free amino group, are relevant for design of promising antitumor and DNA binding compounds.

Novel Thiazolidinone-Azole Hybrids: Design, Synthesis and Antimycobacterial Activity Studies

To develop novel antimycobacterial agents, a new series of thiazolidinone-azole hybrids 4a-b, 5a-b and 6-13 were designed and synthesized. Thiazolidin-4-ones (4a-b and 5a-b) were obtained by the reaction of Schiff bases and hydrazones (2a-b and 3a-b) with mercaptoacetic acid. 5-Benzylidene derivatives (6-13) were gained by treatment of 5a-b with appropriate benzaldehydes according to Knoevenagel condensation. To evaluate their structures H-1 NMR, IR, mass spectrometry and elemental analysis data were used. The target compounds were screened for their antimycobacterial activity against M. tuberculosis H37Rv strain using the microplate alamar blue assay method. Among them, 6, 10 and 12 (MIC: 14.27-14.74 mu M) were found as most active compounds in the series. It was seen that both phenylamino and benzylidene substitutions on thiazolidin-4-one ring caused an improvement in the antimycobacterial activity.

ASSESSMENT OF IN VITRO ANTIOXIDANT ACTIVITY OF SOME NEW FERULIC ACID DERIVATIVES

Aim: The in vitro antioxidant potential of new thiazolidin-4-one derivatives of ferulic acid was evaluated according to the total antioxidant activity and ferric reducing power assays. Material and methods: The ferric reducing power assay was based on the reduction of ferricyanide to ferrocyanide, which form in the presence of ferric chloride a Perl Prussian blue color complex. The total antioxidant activity assay was assessed using phosphomolybdenum method. The results were expressed as effective concentration (EC50) values and ascorbic acid was used as positive control. All determinations were performed in triplicate. Results: It was found that the activity of the tested compounds is influenced by the substituents on phenyl ring of the thiazolidine-4-one moiety. The most active compound was 1i, which contains 2,3-diOH as substituent on phenyl ring. Conclusions: A total of 10 new thiazolidin-4-one derivatives of ferulic acid were investigated for their in vitro antioxidant activity. The most active compound 1i (R=2,3-diOH) proved to be about 4 times more active than ferulic acid and comparable to ascorbic acid in both antioxidant assays.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 10097-02-6. COA of Formula: C6H12O4.

Synthesis and biological activity evaluation of new thiazolidinone-diclofenac hybrid molecules

A novel series of [2-(2,6-dichlorophenylamino)-phenyl]-acetic acid N`-3-(substituted)-4-thiazolidin-5-ylidenemethyl-hydrazide derivatives has been designed and synthesized. The structures of synthesized compounds were confirmed by their H-1 NMR, C-13 NMR and LCMS spectroscopic data. Target compounds were screened for their in vitro anticancer activity according to US NCI protocols, in vitro trypanocidal activity toward Trypanosoma brucei brucei (Tbb) and evaluated for anti-inflammatory activity on the carrageenan edema model in rats. Biological screening data led to identification of compounds 3.3 ([2-(2,6-dichloro-phenylamino)-phenyl]-acetic acid N`-(4-oxo-2-thioxo-thiazolidin-5-ylidenemethyl)-hydrazide) and 3.7 ([2-(2,6-dichloro-phenylamino)-phenyl]-acetic acid N`-(4-oxo-2-thioxo-3-(3-trifluoromethylphenyl)thiazolidin-5-ylidenemethyl)-hydrazide) which demonstrated moderate antitumor activity on the non-small-cell lung cancer NCI-H522 and colon cancer HCT-116 cell lines. Several hit compounds (3.2, 3.4) exhibited the promising and significant inhibition growth of the parasites at micromolar concentrations (IC50 values of 4.8 and 7.06 mu M, respectively). The synthesized compounds also demonstrated considerable anti-inflammatory effect comparable to the reference non-steroidal anti-inflammatory drugs (NSAIDs) diclofenac sodium or ketorolac tromethamine.

Antibacterial evaluation and molecular docking studies of pyrazole-thiosemicarbazones and their pyrazole-thiazolidinone conjugates

A library of pyrazole-thiazolidinone conjugates was synthesized using a molecular hybridization approach through a Vilsmeier-Haack reaction. The compounds were tested for anti-microbial activity against two Gram-positive bacteria (Staphylococcus aureus and methicillin-resistant Staphylococcus aureus) and four Gram-negative bacteria (Escherichia coli, Salmonella typhimurium, Klebsiella pneumonia and Pseudomonas aeruginosa). Among the compounds tested, 3-((2,4-dichlorophenyl)-1-(2,4-dinitrophenyl)-1H-pyrazol-yl)methylene)hydrazinecarbothioamide (3a) and 2-((3-(2-chlorophenyl)-1-(2,4 dinitrophenyl)-1H-pyrazol-4-yl)methyleneamino)thiazolidin-4-one (4b) emerged as the most potent anti-microbial compounds with minimum bactericidal concentrations of < 0.2 mu M against MRSA and S. aureus. Structure-activity relationship analysis further revealed that the presence of 2,4-dichloro moiety surprisingly influenced the activity of the compounds. Molecular docking studies of the compounds into the crystal structure of topoisomerase II and topoisomerase IV suggest that compounds 3a and 4b preferably interact with the targets through hydrogen bonding. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 6118-51-0, in my other articles.

Synthesis of novel inhibitors of alpha-amylase based on the thiazolidine-4-one skeleton containing a pyrazole moiety and their configurational studies

Postprandial hyperglycemia can be controlled by delaying the absorption of glucose resulting from carbohydrate digestion. alpha-Amylase is the initiator of the hydrolysis of polysaccharides, and therefore developing alpha-amylase inhibitors can lead to development of new treatments for metabolic disorders like diabetes mellitus. In the present work, we set out to rationally develop alpha-amylase inhibitors based on the thiazolidine-4-one scaffold. The structures of all these newly synthesized hybrids were confirmed by spectroscopic analysis (IR, H-1-NMR, MS). The appearance of two sets of signals for some protons in H-1 NMR revealed the existence of a mixture of 2E, 5Z (37.1-42.0%) and 2Z, 5Z isomers (58.4-62.8%), which was further supported by DFT studies. All the newly synthesized compounds have potential inhibitory properties as revealed through in vitro alpha-amylase inhibition activity. Compound 5a at 100 mu g mL(-1) concentration showed a remarkable inhibition of 90.04%. In vitro alpha-amylase inhibition was further supported by docking studies of compound 5a against the active site of human pancreatic alpha-amylase (PDB ID: 2QV4). The docking studies revealed that the bonding interactions found between 5a and human pancreatic alpha-amylase are similar to those responsible for alpha-amylase inhibition by acarbose.
