1,3-Thiazolidin-4-ones: Biological Potential, History, Synthetic Development and Green Methodologies

Background: We present here the synthesis of 1,3-thiazolidin-4-one (1) and its functionalised analogues, such as the classical isosteres, glitazone (1,3-thiazolidine-2,4-dione) (2), rhodanine (2-thioxo-1,3-thiazolidin-4-one) (3) and pseudothiohydantoin (2-imino-1,3-thiazolidin-4-one) (4) started in the mid-nineteenth century to the present day (1865-2018). The review focuses on the differences in the representation of the molecular structures discussed here over time since the first discussions about the structural theory by Kekule, Couper and Butlerov. Moreover, advanced synthesis methodologies have been developed for obtaining these functional group, including green chemistry. We discuss about its structure and stability and we show the great biological potential. Conclusion: The 1,3-thiazolidin-4-one nucleus and functionalised analogues such as glitazones (1,3-thiazolidine-2,4-diones), rhodanines (2-thioxo-1,3-thiazolidin-4-ones) and pseudothiohydantoins (2-imino-1,3-thiazolidine-2-4-ones) have great pharmacological importance, and they are already found in commercial pharmaceuticals. Studies indicate a promising future in the area of medicinal chemistry with potential activities against different diseases. The synthesis of these nuclei started in the mid-nineteenth century (1865), with the first discussions about the structural theory by Kekule, Couper and Butlerov. The present study has demonstrated the differences in the representations of the molecular structures discussed here over time. Since then, various synthetic methodologies have been developed for obtaining these nuclei, and several studies on their structural and biological properties have been performed. Different studies with regards to the green synthesis of these compounds were also presented here. This is the result of the process of environmental awareness. Additionally, the planet Earth is already showing clear signs of depletion, which is currently decreasing the quality of life.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 542-05-2 help many people in the next few years. Recommanded Product: 3-Oxopentanedioic acid.

Synthesis, Molecular Docking and Antimicrobial Activities of 5-(4-substituted-benzyl)-2-(furan/thiophen-2-ylmethylene hydrazono)thiazolidin-4-ones

In our present work, we reported an effective synthesis, molecular docking, and antimicrobial properties of novel 5-(4-substituted-benzyl)-2-(furan/thiophen-2-ylmethylene hydrazono) thiazolidin-4-ones (6a-g) and (7a-i). The structures of the synthesized compounds (6a-g) and (7a-i) were elucidated by 1H-NMR spectroscopy. The molecular docking studies were performed for all the synthesized compounds against GlcN-6P using AutoDock-tools-1.5.6 and recorded the extent of H-bonding and binding affinities. The preselected compounds via molecular docking were further tested for in vitro antimicrobial activity against five bacterial strains (Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, Staphylococcus aureus) and two fungal strains (Candida albicans and Cryptococcus neoformans). The antimicrobial findings exhibited that the compounds possessed significant antimicrobial potential.

Surface characterization of thiazolidinone derivatives by inverse gas chromatography

Inverse gas chromatography at infinite dilution was used for the first time to determine the adsorption properties and acid-base contributions to the surface energy of thiazoldin-4-ones bearing heteroaryl substituents. 3-(6-Methyl-2-pyridyl)-2-(2-thienyl)-1,3-thiazolidin-4-one (MPTT) and 3-(6-Methyl-2-pyridyl-2-(3-methyl-2-thienyl-1,3-thiazolidin-4-one (MPMTT) were freshly synthesized via one-pot three component condensation reaction. The retentions of nonpolar solvents such as n-hexane, n-heptane, n-octane, n-nonane, n-decane and other acidic, basic and amphoteric probes such as tetrahydrofurane, dichloromethane, chloroform, acetone and ethyl acetate used without further purification on MPTT and MPMTT were measured in the temperature ranges from 303 to 333 K by inverse gas chromatography (IGC). The dispersive component of the surface energy, gamma(D)(S) of studied adsorbent surface was estimated using retention times of different nonpolar organics in the infinite dilution region. Dispersive components of the surface energies, gamma(D)(S)according to Fowkes and Dorris-Gray approaches and the acid, K-A and base, K-D constants for the 3-(6-Methyl-2-pyridyl)-2-(2-thienyl)-1,3-thiazolidin-4-one and 3-(6-Methyl-2-pyridyl)-2-(3-methyl-2-thienyl-1,3-thiazolidin-4-one were calculated.

One-pot four-component synthesis of thiazolidin-2-imines using Cu-I/Zn-II dual catalysis: A new class of acetylcholinesterase inhibitors

An efficient one-pot four-component strategy involving aldehydes, amines, alkynes and isothiocyanates has been developed to access a novel series of thiazolidine-2-imines (5a-x). This process operates under the action of a cooperative catalysis composed of Cu(I) and Zn(II) delivering the desired five-membered heterocyclic compounds in good to excellent yields. Notably, this transformation avoids the use of pre-formed imines or propargylamines and proceeds via an intramolecular 5-exo-dig hydrothiolation reaction of the in situ formed propargyl thiourea. Furthermore, the biological application of these motifs was demonstrated in terms of their strong acetylcholinesterase (AChE) inhibitory activity where compound 5s was identified as the lead AChE inhibitor with an IC50, value of 0.0023 +/- 0.0002 mu M, 88-folds stronger inhibition than standard drug (neostigmine methyl sulphate; IC50, = 0.203 +/- 0.004 mu M). Molecular docking analysis reinforced the in vitro biological activity results revealing the formation of several useful interactions of the potent lead with amino acid residues in the active site of the enzyme.

Visible-light-driven photocatalytic activity of ZnO/g-C3N4 heterojunction for the green synthesis of biologically interest small molecules of thiazolidinones

Designing a photocatalytic system with complementary properties including high surface area, high loading, extraordinary electronic properties, and easy separation for increases photocatalytic performance has remained a challenge in photocatalytic applications. Herein, an environmentally benign approach was developed to fabricate graphitic carbon nitride (g-C3N4) decorated with nanorods zinc oxide (ZnO). The photocatalytic activity of ZnO decorated on the g-C3N4 surface was developed in the synthesis of 1,3-thiazolidin-4-ones and bis-thiazolidinones under very mild and sustainable reaction conditions. The reaction can be carried out by utilizing visible light without the requirement of any additive and other external sources of energy. It was found that the proposed photocatalyst is a more facile, recyclable, large-scale application and provides some new insights into the stabilization of semiconductors for a variety of applications.

Design, graph theoretical analysis, density functionality theories, Insilico modeling, synthesis, characterization and biological activities of novel thiazole fused quinazolinone derivatives

A series of 2-(2-substituted benzylidenehydrazinyl-2-oxopropyl)-3-(4-[4-oxo-2-phenylthiazolo din-3-yl]phenyl)quinazolin-4(3H)-one 7a-7l were synthesized and characterized by IR, H-1-NMR, C-13-NMR, mass spectroscopy and elemental analyses. In this present study, the density functionality theory was performed to identify drug stability. Further we introduced graph theoretical analysis by utilised Kyoto Encyclopedia of Genes and Genomes (KEGG) database and Cytoscape software to identify drug target. Based on the observed drug target insilico modeling was executed to know effective drug. The antiepileptic effects of title compounds were evaluated by using MES and subcutaneous pentylenetetrazole (scPTZ) test. Acute neurological toxicity of title compounds was studied by using standardized rotorod test. After 0.5 hr of period many of the compounds showed anticonvulsant activity at MES or scPTZ test. Comparison of the biological activity of test compounds with its chemical structures indicates that, compounds possessing electron donating group exhibited superior activity than the analogs having electron withdrawing moieties. Among the electron donating group tested, amino derivative exhibited good activity than rest of derivatives. From the study it was concluded that, the compound 7j was established as very potent compared with rest of the compounds and standard drugs subjected to biological studies. Thus the compound 2-(2-[4-aminobenzylidene]hydrazinyl-2-oxopropyl)-3-(4-[4-oxo-2-phenylthiazolidin-3-yl]phenyl) quinazolin-4(3H)-one (7j) came out as pilot derivative without any neurotoxicity with a wide spectrum of antiepileptic activity.

Rapid induction of apoptosis in tumor cells treated with a new platinum(II) complex based on amino-thiazolidinone

Thiazolidinone derivatives have been previously shown significant anti-cancer activities. Two aminothiazolidinone complexes, (Pt(HTone)Cl] (1) and [Cu(HTone)Cl] (3) (HTone = (Z)-2-((E)-(1-(pyridin-2-yl)ethylidene)hydrazono)thiazolidin-4-one) and one ethyl-modified [Pt(ETone)Cl-2] (2) (ETone = (Z)-3ethyl-2-((E)-(1-(pyridin-2-yl)ethylidene) hydrazono)thiazolidin-4-one)], were designed and synthesized in order to explore novel metal-based antitumor agents. MTT assay indicated that 1 and 3 were markedly cytotoxic to MCF-7, HepG-2 and NCI-H460 tumor cells, superior to both cisplatin and the HTone ligand. Massive dead cells were observed as early as 6 h when treated with 1, indicating rapid action of 1 as compared to that of other compounds. More interestingly, Hoechst 33342 staining and flow cytometry analysis illustrated that only complex 1 could induce obvious cell apoptosis within 12 h, which was associated with the high-expression of Bax and cleavage of caspase-3 from 35 kDa to 17 kDa. By means of ICP-MS assay, we found complex 1 could largely accumulate in tumor cells in a short time. Additionally, complex I showed no cross resistance against the cisplatin-resistant cells.

Evaluation of new 2-hydroxy-N-(4-oxo-2-substituted phenyl-1,3- thiazolidin-3-yl)-2-phenylacetamide derivatives as potential antimycobacterial agents

A small collection of 2-hydroxy-N-(5-methyl/nonsubstituted 4-oxo-2-substituted phenyl-1,3-thiazolidin-3-yl)-2-phenylacetamides (3-16) was synthesized from the cyclocondensation of 2-hydroxy-2-phenyl-N’-[(substitutedphenyl)methylene]acetohydrazides (2) and mercaptoethanoic acid or 2-mercaptopropanoic acid, characterized with spectral and elemental analysis. In order to explore their antimycobacterial potential, newly synthesized fourteen compounds were screened for their inhibitory activity against Mycobacterium tuberculosis strain H37Rv at 6.25 mu g/mL with in-vitro primary tests. Compound 7 was found to provide the highest inhibition (98%) M. tuberculosis strain H37Rv, while most of the new derivatives showed different inhibition ratios. For the search of the putative targets which are considered as related to the antimycobacterial activity of these molecules, docking studies were performed. With molecular dynamic simulations, further possible interactions between ligands and the active site of the selected enzymes were investigated. Eventually, molecular modelling studies indicated that at least part of the mechanism of action of these compounds may be mediated by inhibition of MtInhA.
