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.

4-Thiazolidinone Derivatives as MMP Inhibitors in Tissue Damage: Synthesis, Biological Evaluation and Docking Studies

Nine 2-(1,2-benzothiazol-3-yl)-N-(4-oxo-2-phenyl-1,3-thiazolidin-3-yl)propanamides combining a benzisothiazole and 4-thiazolidinone in one framework were designed and synthesized. The aim of the study was to verify their effectiveness to affect the inflammatory/oxidative process in which free oxygen and nitrite (ROS and RNS) radicals, inflammatory mediators, such as nuclear factor kappa B (NF-kappa B), and matrix metalloproteinases (MMPs) are involved. Docking studies of all the compounds were performed in order to explore their binding mode at the MMP-9 protein. An appreciable anti-inflammatory/potential wound healing effects of the tested compounds was highlighted. Derivative 23, bearing a 4-carboxyphenyl substituent at C2 of the 4-thiazolidinone ring, exhibited the highest activity, being able to inhibit MMP-9 at nanomolar level(IC50 = 40 nM).

Discovery of Methyl (5Z)-[2-(2,4,5-Trioxopyrrolidin-3-ylidene)-4-oxo-1,3-thiazolidin-5-ylidene]acetates as Antifungal Agents against Potato Diseases

Synthesis, isomerism, and fungicidal activity against potato diseases of new (5Z)-[2-(2,4,5-trioxopyrrolidin-3-ylidene)-4-oxo-1,3-thiazolidin-5-ylidenelacetate derivatives with 1,3-thiazolidine-4-one and pyrrolidine-2,3,5-trione moieties linked by an exocyclic C=C bond were described. Their structures were clearly confirmed by spectroscopic and spectrometric data (Fourier transform infrared spectroscopy, H-1 and C-13 nuclear magnetic resonance, and mass spectrometry), elemental analysis, and X-ray diffraction crystallography. A bioassay for antifungal activity in vitro against Phytophthora infestans, Fusariun solani, Alternaria solani, Rhizoctonia solani, and Colletotrichum coccodes demonstrated that 2,4,5-trioxopyrrolidin-1,3-thiazolidine derivatives exhibited a relatively broad spectrum of antifungal activity. One of the compounds showed considerable activity against all of the strains; in the case of F. solani, P. infestans, and A. solani, it possesses comparable or better fungicidal efficacy than the positive control Consento. Consequently, this compound is a promising fungicidal candidate for plant protection.

Synthesis and isomerization of acridine substituted 1,3-thiazolidin-4-ones and 4-oxo-1,3-thiazolidin-5-ylidene acetates. An experimental and computational study

Acridine thiosemicarbazones 3a-g, obtained through a two-step reaction between aromatic iso-thiocyanates and hydrazine followed by the treatment with acridin-9-carbaldehyde, in reaction with bifunctional reagents; methyl bromoacetate (MBA) and diethyl acetylenedicarboxylate (DEAD) afforded acridin-thiazolidinone derivatives 4a-g and 7a-f and not their regioisomers 6a-g and 9a-f. Derivatives 4a-g and 7a-f exhibit Z(C2N6)E(N7c8) configuration. Upon standing in DMSO-d(6) the thiazolidinones 4a-g and 7a-f spontaneously isomerized into Z(C2N6)Z(N7C8) isomers 5a-g and 8a-f to give a mixture of the both stereoisomers. All compounds were fully characterized by multinuclear NMR, mass spectrometry (MS) and X-ray crystal structure of 4b is also described. X-ray diffraction study revealed that the representative compound 4b crystallized in the monoclinic crystal system with the C2/c space group and Z = 4. Intramolecular C1′-H1′ center dot center dot center dot N-7 hydrogen bond between the acridine proton H-1′ and nitrogen N-7 of linker existed. This hydrogen bond is responsible for the E isomerism on C-8 atom which was observed in the NMR experiments. Quantum-chemical calculations and NOESY experiments confirmed Z(C2N6)Z(N7C8) configuration of the transformed stereoisomers 5a-g and 8a-f. (C) 2017 Elsevier B.V. All rights reserved.

Catalyst-, solvent- and desiccant-free three-component synthesis of novel C-2, N-3 disubstituted thiazolidin-4-ones

Herein it is provided an efficient, environmentally friendly and one-pot procedure for the synthesis of a library of new and diversely substituted 1,3-thiazolidin-4-ones in short reaction times and good yields through a solvent-, catalyst- and desiccant-free three-component process. Reactions proceeded by treatment of primary benzyl(aryl)amines with aromatic aldehydes (and ketones) and 2-mercaptoacetic acid acting as both reagent and self-catalyst. All reactions were performed in sand bath instead of the commonly used oil bath avoiding the generation of undesired volatile materials proceeding of the thermal decomposition of the oils. IR, Mass and NMR experiments as well as X-ray diffraction confirmed structures of the obtained products. (C) 2016 The Authors.

Synthesis and antiviral activity of camphor-based 1,3-thiazolidin-4-one and thiazole derivatives as Orthopoxvirus-reproduction inhibitors

The Orthopoxvirus genus belongs to the Poxviridae family and includes variola virus (smallpox), cowpox virus, monkeypox virus and vaccinia virus (VV). Smallpox is considered one of the great epidemic disease scourges in human history. It has currently been eradicated; however, it remains a considerable threat as a biowarfare or bioterrorist weapon. The poxvirus, VV, serves as a model virus from which new antiviral therapies against Orthopoxviruses can be identified. Here, a series of nitrogen-sulphur containing heterocycles such as 1,3-thiazolidin-4-one and thiazoles containing a 1,7,7-trimethylbicyclo[2.2.1]heptan scaffold were synthesized and screened for their antiviral activity. The bioassay results showed that the 4b, 4c and 4e thiazoles, which contained a substituted benzene ring, were able to inhibit VV reproduction with IC50 values in the 2.4-3.7 micromolar range whilst exhibiting moderate cytotoxicity. Among the thiazolidin-4-one derivatives, compound 8b, which contained a 4-methylbenzylidene group, displayed good inhibitory activity (IC50 = 9.5 M) and moderate toxicity.
