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.
