Synthesis of Diflunisal Thiazolidinones as Anticancer Agents

A series of diflunisal 4-thiazolidinones were synthesized. Some selected compounds were determined at one dose towards the full panel of 60 human cancer cell lines by National Cancer Institute. 2′,4′-Difluoro-4-hydroxy-N-[4-oxo-2-(thiophen-2-yl)-1,3-thiazolidin-3-yl]biphenyl-3-carboxamide (4a) demonstrated the most marked effect on K-562 cancer cell line with 58.59 % growth inhibition at 10 mu M. Compound 4a was evaluated in vitro using the MTT colorimetric method against human leukemia cell line K-562 and mouse embryonic fibroblasts cell line NIH-3T3 at different doses for cell viability and growth inhibition. Compound 4a exhibited anticancer activity with IC50 value of 5.2 mu M against K-562 cells and did not display cytotoxicity towards NIH-3T3 cells compared with diflunisal. In addition, this compound could be an interesting prototype as an antiproliferative agent.

Chemical Synthesis, Mechanism of Action and Anticancer Potential of Medicinally Important Thiazolidin-2,4-dione Derivatives: A Review

Thiazolidin-2,4-dione (TZD) possessing an active methylene constitute an important chemical class of compounds for the development of new drugs. So, many scholars have synthesized these derivatives as target molecules and evaluated their biological potential. Currently, some of the TZDs are synthesized to treat human cancers stating high levels of PPAR gamma because it is expected that activation of PPAR gamma arbitrates their anticancer activity because PPAR gamma ligands have recently been established to affect differentiation, cell proliferation and apoptosis of different cell types. In the present review, the synthesis of various derivatives of thiazolidine-2,4-diones, their mechanism of action and anticancer activity have been highlighted.

Quorum Sensing Inhibitor Activities of Celecoxib Derivatives in Pseudomonas aeruginosa

Background: A series of novel N-(substituted aryl/alkylcarbamothioyl)-4-[5-(4-methylphenyl)3-( trifluoromethyl)-1H-pyrazol-1-yl] benzene sulfonamides [SGK 318, 319, 320, 324, 327] and N-(3-substitutedaryl/ alkyl-4-oxo-1,3-thiazolidin-2-ylidene)-4-[5-(4-methylphenyl)-3-(trifluoromethyl)-1H-pyrazol-1-yl] benzenesulfonamides[SGK 328, 329, 330, 334, 337] were synthesized and tested for their quorum sensing inhibitor (QSI) capacity using quorum sensing inhibitor selector 1 (QSIS1) bioassay. Findings: QSIS assay revealed that SGK 324, SGK 327 and SGK 330 have the potentials to interfere with QS system in QS inhibitor selector1 (QSIS1) reporter strain. Moreover, these compounds were found to significantly affect QS regulated elastase and biofilm productions in Pseudomonas aeruginosa PA01 strain without affecting its growth. Molecular modeling experiments suggested that SGK 330 fits within the binding site of LasR protein of P. aeruginosa. SGK 324 and 327 also bind LasR provided that they adopt a s-trans/s-cis conformation with respect to the thiourea function. Results and Conclusion: Results of this study indicated that these compounds could be developed as new QS inhibitors without killing the bacteria but as antivirulence compounds to restrict virulence of clinically important human pathogens.

Synthesis, Characterization, Antibacterial and Antioxidant Potency of N-Substituted-2-Sulfanylidene-1,3-Thiazolidin-4-one Derivatives and QSAR Study

Background: Rhodanine is known for its potential and important role in the medicinal chemistry since its derivatives exhibit a wide range of pharmacological activities such as antibacterial, antifungal, antidiabetic, antitubercular, anti-HIV, antiparasitic, antioxidant, anticancer, antiproliferative and anthelmintic agents. Objectives: Since N-substituted rhodanine synthons are rarely commercially available, it is desirable to develop a straightforward synthetic approach for the synthesis of these key building blocks. The objective was to synthesize a series of rhodanine derivatives and to investigate their antimicrobial and antioxidant activity. Also, in order to obtain an insight into their structure-activity relationship, QSAR studies on the antioxidant activity were performed. Methods: H-1 and C-13 FTNMR spectra were recorded on Bruker Avance 600 MHz NMR Spectrometer, mass analysis was carried out on ESI+ mode by LC-MS/MS API 2000. 2,2-Diphenyl-1-picrylhydrazyl radical scavenging activity (% DPPH) was determined in dimethylsulfoxide (DMSO) as a solvent. The antibacterial activity was assessed against Bacillus subtilis, Staphylococcus aureus (Gram positive) and Escherichia coli, Pseudomonas aeruginosa (Gram negative) bacteria in terms of the minimum inhibitory concentrations (MICs) by a modified broth microdilution method. Results: A series of N-substituted-2-sulfanylidene-1,3-thiazolidin-4-ones were synthesized and characterized by H-1 NMR, C-13 NMR, FTIR, GC MS, LCMS/ MS and C,H,N,S elemental analysis. Most of the synthesized compounds showed moderate to excellent antibacterial activity (MIC values from 125 mu g/ml to 15.62 mu g/mL) and DPPH scavenging activity (from 3.60% to 94.40%). Compound 2-thioxo-3-(4-(trifluoromethyl)-phenyl)thiazolidin-4-one showed the most potent activity against Escherichia coli (3.125 mu g/mL), equivalent to antibiotic Amikacin sulphate and against Staphylococcus aureus (0.097 mu g/ml), 100 times superior then antibiotic Amikacin sulphate. It has also shown a potent antioxidant activity (95% DPPH scavenging). Two best QSAR models, obtained by GETAWAY descriptor R7p(+), Balabans molecular connectivity topological index and Narumi harmonic topological index (HNar), suggest that the enhanced antioxidant activity is related to the presence of pairs of atoms higher polarizability at the topological distance 7, substituted benzene ring and longer saturated aliphatic chain in N-substituents. Conclusion: A series of novel N-substituted-2-thioxothiazolidin-4-one derivatives were designed, synthesized, characterized and evaluated for their antibacterial and antioxidant activity in vitro. Majority of the compounds showed excellent antibacterial activity compared to ampicillin and few of them have an excellent activity as compared to Chloramphenicol standard antibacterial drug. The QSAR study has clarified the importance of presenting a pairs of atoms higher polarizability, such as Cl and S at the specific distance, as well as the substituted benzene ring and a long saturated aliphatic chain in N-substituents for the enhanced antioxidant activity of 2-sulfanylidene-1,3thiazolidin-4-one derivatives.

The present paper is designed to explore the potential of an important class of heterocycles coumarinylthiazolyl iminothiazolidinone to inhibit jack bean urease. The final products 6a-j were prepared by condensation of substituted aldehydes with intermediate 5 in sodium methoxide/methanol mixture. The synthesized compounds were characterized by their FTIR, H-1, C-13 NMR and mass spectral data. The synthesized coumarinylthiazolyl iminothiazolidinone hybrids 6 a-j were evaluated for their potential to inhibit urease activity. All the synthesized derivatives showed remarkable inhibitory activity with IC50 ranging 8 to 34 nM, while IC50 of standard thiourea is 18.5 nM. The compound 5-(2,4-Dichlorobenzylidene)-2-(4-(2-oxo-2H-chromen-3-yl)thiazol-2-yl imino) thiazolidin-4-one 6 h bearing 2,4-di-chloro substituted phenyl ring exhibited excellent activity with IC50 value 8 nM. In silico molecular docking studies was performed against urease enzyme PDBID 4H9 M and predicted possible binding modes in catalytic site for these active compounds. The thiazole nitrogen in compound 6 h formed a strong hydrogen bonding interaction with side chain Gln635 having distance 2.01 angstrom and rest part of this inhibitor is present close to Val640. The most potent derivative 6 h have highest binding affinity with binding energy -6.178 kcal/mol. It is concluded based upon our results that 6 a and 6 h are most promising compounds from this series and provide a basis for rationale design of most potent urease inhibitors.
