Environmentally Benign Synthesis of 4-Thiazolidinone Derivatives Using a Co/Al Hydrotalcite as Heterogeneous Catalyst

The present effort describes facile and environmentally benign synthesis of 4-thiazolidinone via oxidative cyclocondensation of benzyl alcohols, various substituted aromatic anilines and thioglycolic acid using a Co-Al hydrotalcite based heterogeneous catalyst (Co@HT) in methanol act as a solvent. We have synthesized three types of Co@HT with different molar ratio Co@HT-2 (1:1), Co@HT-3 (2:1), Co@HT-4 (3:1). Characterization of synthesized Co@HT catalyst using various analysis techniques such as FT-IR, powder XRD, SEM, XPS, EDS, DTG-TGA and N-2 physical adsorption. Among the synthesized hydrotalcite, Co-HT-3 exhibit admirable catalytic activity towards oxidation of benzyl alcohol followed by cyclocondensation of respective aldehydes, anilines and thioglycolic acid into the corresponding 4-thiazolidinones in methanol at 60 C-omicron using O-2 as a oxidant. Furthermore, after end of the reaction, the catalyst is easily recovered and eco-friendly without any considerable loss in its catalytic efficiency. [GRAPHICS] .

Symmetrical aryl linked bis-iminothiazolidinones as new chemical entities for the inhibition of monoamine oxidases: Synthesis, in vitro biological evaluation and molecular modelling analysis

The multifactorial nature of Parkinson’s disease necessitates the development of new chemical entities with inherent ability to address key pathogenic processes. To this end, two series of new symmetrical 1,2- and 1,4-bis(2-aroyl/alkoylimino-5-(2-methoxy-2-oxoethylidene)-4-oxo-thiazolidin-3-yl) benzene derivatives (3a-g and 5a-e) were synthesized in good yields by the cyclization of 1,2- and 1,4-bis (N ‘-substituted thioureido) benzene intermediates with dimethyl acetylenedicarboxylate (DMAD) in methanol at ambient temperature. The bis-iminothiazolidinone compounds were investigated in vitro for their inhibition of monoamine oxidase (MAO-A & MAO-B) enzymes with the aim to identify new and distinct pharmacophores for the treatment of neurodegenerative disorders like Parkinson’s disease. Most of the designed compounds exhibited good inhibitory efficacy against monoamine oxidases. Compound 5a was identified as the most potent inhibitor of MAO-A depicting an IC50 value of 0.001 mu M, a 4-fold stronger inhibitory strength compared to standard inhibitor (clorgyline: IC50 = 0.0045 mu M). Molecular docking studies provided insights into enzyme-inhibitor interactions and a rationale for the observed inhibition towards monoamine oxidases. (C) 2016 Elsevier Inc. All rights reserved.

The XRD patterns of 4-ATS and 5-ATS in powder form were recorded and found to be polycrystalline with monoclinic crystal system. Thin films of 4-ATS and 5-ATS were successfully prepared by thermal evaporation technique onto optical flat quartz substrates. Linear and nonlinear optical properties of 4-ATS and 5-ATS were investigated by spectrophotometric measurements. The spectral distribution of refractive index of 5-ATS thin films showed normal dispersion in the non-absorbing region of spectra, while 4-ATS showed nonlinear response. The optical energy gap and the electronic transition type for 4-ATS and 5-ATS were calculated. The electronic absorption and emission spectra were recorded for pristine and UV-irradiated 4-ATS and 5-ATS thin films. The absorption coefficient spectra for 4-ATS and 5-ATS were found to decrease with increasing UV exposure time, while the intensity of emission spectra for both of the derivatives were enhanced with increasing UV exposure time. Recovery in dark reversed the effect of UV-radiation.

Synthesis and Antimicrobial Screening of Novel Azetidin-2-ones Derived from Pyromellitic Diimide via [2+2]-Cycloaddition Reaction

A series of novel 2-azetidinone derivatives have been obtained starting from pyromellitic dianhydride. Pyromellitic dianhydride was converted to pyromellitic diimide using sodium cyanate, and the diimide was alkylated with ethyl chloroacetate. The resulting diester was treated with hydrazine hydrate to obtain dihydrazide which reacted with substituted pyridine-2-carbaldehydes to give the corresponding Schiff bases, and [2+2]-cycloaddition of the latter with chloroacetyl chloride in the presence of triethylamine afforded the target azetidin-2-one derivatives. The newly synthesized compounds showed high antimicrobial activities against some bacterial and fungal strains.
