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.

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 94-41-7, in my other articles.

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.

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.

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.

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.

Utility of chloroacetonitrile in construction of some hitherto novel pyrazole and thiazole derivatives

2-(-Piperidin-1-yl) acetamide (2) was easily prepared by reacting chloroacetonitrile with piperidine. Furthermore, (2) was allowed to react with different aromatic aldehydes to afford novel arylidene derivatives (3a,b). Unexpectedly, 2-oxo-4-hydroxy-thiazole (5) was obtained instead of 2-(piperidin-1-yl-methylene) thiazolidin-4-one (4) when (2) was treated with mercaptoacetic acid under fusion conditions. Subsequent treatment of (5) with aromatic aldehydes and either malononitrile or cyanoacetamide (1:1:1 molar ratios) produced the hitherto unknown pyrano[2,3-d] thiazole derivatives (6a,b) and (7). Novel pyrazole derivatives (8a, b) and (9) were synthesized upon cyclocondensation of (2) with aromatic aldehydes and hydrazine hydrate. Unfortunately, attempts to prepare novel isoxazole derivatives by utilizing hydroxylamine instead of hydrazine hydrate following the previous procedure were failed. Surprisingly, the uncyclized products (10a,b) were obtained rather than 3-hydroxy-4-piperidinyl-isoxazole (11a,b). Upon refluxing thiosemicarbazide with (2) and aromatic aldehydes under the same conditions, pyrazolinone carbothioamides (12), (13) and (14a-c) were obtained.

New thiazoldinone substituted 2,6-diarypiperidin-4-one: Synthesis, crystal structure, spectral characterization, binding mode with calf thymus DNA

A series of 2,6-diarylpiperidin-4-ylidene thiazolidin-4-one derivatives (15-21) were efficiently synthesized using a green and recyclable catalyst Amberlit IR-120H resin under microwave irradiation. All the compounds were characterized by elemental analysis, FT-IR, H-1, C-13 NMR spectra. The conformation of the compound was unambiguously assigned by 2D NMR spectral analysis. Single crystal X-ray diffraction recorded for compound 21 and the data indicate that the compound crystallized in triclinic system with space group P (1) over bar. The observed chemical shifts and coupling constants suggested that the piperidone ring (15-21) adopts in chair conformation with equatorial orientations of the aryl groups. In solid state the configuration about C=N double bond is syn to C-5 carbon. All the compounds were screened for their in vitro antibacterial and antimycobacterial activities. Among the tested, compounds 17 and 18, were found to be potent inhibition with MIC values in the range of 0.2-0.8 mu g/mL. The interactions of the compounds with calf thymus DNA were investigated by spectroscopic method and the results indicated that compounds bound to Deoxyribo Nucleic Acid (DNA) by groove binding mode.
