In the title compound, C(9)H(13)NOS(2), the complete mol-ecule is generated by crystallographic mirror symmetry, with all the non-H atoms of the rhodanine (2-thioxo-1,3-thia-zolidin-4-one) system and two C atoms of the cyclo-hexyl ring lying on the reflecting plane. The conformation is stabilized by intra-molecular C-H⋯O and C-H⋯S inter-actions. In the crystal, weak π-π inter-actions at a dista...

Polyphenolics were extracted from peels, pulp and kernels of mango fruits (Mangifera indica L. cv. 'Tommy Atkins') and characterized by high-performance liquid chromatography/electrospray ionization mass spectrometry. In the peel 18 gallotannins and five benzophenone derivatives were detected which were tentatively identified as galloylated maclurin and iriflophenone glucosides. Twenty-one and ...

A series of rhodanine derivatives was prepared. The synthetic approach, analytical and spectroscopic data of all synthesized compounds are presented. Lipophilicity of all the discussed rhodanine derivatives was analyzed using the RP-HPLC method. The compounds were tested for their ability to inhibit photosynthetic electron transport (PET) in spinach (Spinacia oleracea L.) chloroplasts and reduc...

We describe a new chromogenic substrate and assay for determining N-acetyl-beta-D-glucosaminidase (EC 3.2.1.30; NAG) activity in normal and pathological human urine. The novel substrate, ammonium 5-[4-(2-acetamido-2-deoxy-beta-D-glucopyranosyloxy)-3- methoxyphenylmethylene]-2-thioxothiazolidin-4-one-3-ethan oate (VRA-GlcNAc), is prepared by condensation of vanillyl N-acetyl-beta-D-glucosaminide...

A green, efficient synthesis of 5-arylidene rhodanine and 2,4-thiazolidinedione derivatives without using any external catalyst in polyethylene glycol (PEG) at 80°C has been described. Reaction procedure is very simple, short, and obtained yields are very high.

In the title compound, C(10)H(9)NOS(2), the dihedral angle between the rhodanine (2-thioxo-1,3-thia-zolidin-4-one) and 3-methyl-phenyl rings is 83.30 (3)°. The H atoms of the methyl group are disordered over two set of sites with an occupancy ratio of 0.58 (3):0.42 (3). In the crystal, the mol-ecules inter-act by way of C-H⋯π and C=O⋯π inter-actions.

Plausible mechanisms of the ultrafast electron injection and the significant dependence of the power conversion efficiency on the anchor group for the triphenylamine-based dye-sensitized TiO2 solar cells have been explored by the density functional calculations. Calculations show that the ultrafast charge recombination on the surface trap state of the dye-sensitized TiO2 system can be ascribed ...

Raltegravir was the first HIV-1 integrase inhibitor that gained FDA approval for use in the treatment of HIV-1 infection. Because of the emergence of IN inhibitor-resistant viral strains, there is a need to identify innovative second-generation IN inhibitors. Previously, we identified 2-thioxo-4-thiazolidinone (rhodanine)-containing compounds as IN inhibitors. Herein, we report the design, synt...
