a series of n-substituted-2,4-thiazolidinedione derivatives (tzds) were prepared via n-alkylation of 2,4-tzd at position 3 using substituted benzyl halides. synthesized n-substituted-2,4-tzd was then substituted at position 5 with substituted aromatic aldehyde according to knoevenagel condensation method. structures of the compounds were elucidated using various spectral techniques viz. ir, 1hn...

This study reported a one-pot process used to synthesize poly[(linoleic acid)-g-(styrene)-g-(ε-caprolactone)] (PLina-g-PSt-g-PCL) graft copolymers. The was carried out by combining the atom transfer radical polymerization (ATRP) of styrene with ring-opening (ROP) ε-caprolactone from polymeric linoleic acid having hydroxyl groups and bromine (PLina-Br) in main chain. characterization products ac...

The aim of this study was to characterize the phytochemicals and investigate antimicrobial efficacy shade dried roots Asparagus adscendens. powder were extracted with chloroform after removal solvent under reduced pressure subjected for chromatographic separation. After column chromatography purification five compounds i.e .hexacosanyltriacontanoate, hexatriacontanone, 2,3,5,7-tetramethoxydi hy...

New N-substituted ?-aminonitrile derivatives from menthol were synthesized by consecutive succinic ester formation, propargylation, 1,3-dipolar Huisgen cycloaddition and Strecker reaction. The structures of the compounds confirmed diverse spectroscopic techniques including 1HNMR, 13C-NMR, ESI-MS IR. novel evaluated for their in vitro antibacterial activities against Staphylococcus aureus as Gra...

ethylammonium propionate with high polarity and ionic conductivity was synthesized andcharacterized with 1hnmr and ir. this ionic liquid which is prepared from readily available startingmaterial in high yield shows reasonably high at viscosity and heat stability up to 150 °c. this ionicliquid is able to dissolve most of organic solvents due to the hydrogen interaction between ionicliquid and th...

VEGFR-2 is a critical target for the treatment of solid tumors. This work represents synthetic approaches to new class fenamate-based derivatives with essential pharmacophoric properties comparable inhibitors. The reaction tolfenamic acid hydrazide substituted phenacyl bromide, and phenylisothiocynate produced novel (TA) (compounds 4 5). molecules were validated using spectroscopic techniques s...
