Pimpinella essential oils and isolated compounds were screened for their inhibitory activity against NF-kappaB mediated transcription in SW1353 cells. Twelve oils were effective in inhibiting NF-kappaB mediated transcription. Especially the roots of P. corymbosa, P. tragium and P. rhodanta showed potent activities with IC(50) values of 2, 3 and 6 microg/mL, respectively. Five pure compounds, 7 ...

This paper focuses on the estimation of a …nite dimensional parameter in a linear model where the number of instruments is very large or in…nite. In order to improve the small sample properties of standard instrumental variables (IV) estimators, we propose three modi…ed IV estimators based on three di¤erent ways of inverting the covariance matrix of the instruments. These inverses involve a reg...

The last few years have witnessed an enormous study in the area of integrated hydrological modeling with GIS application. In this research, attempt was made to critically look at the application of HEC-GeoHMS which is an extension of ArcView in HEC-HMS; an HEC package which is a new generation of software being developed for rainfall-runoff simulation. The main role of HEC-GeoHMS is to formulat...

A series of 2-amino pyridine-3-carbinitrile derivatives incorporated coumarin moiety has developed via multicomponent condensation of 3-acetyl-2H-chromen-2-one, arylaldehydes, malononitrile and ammonium acetate utilizing Brønsted acidic ionic liquid, (4-sulfobutyl)tris(4-sulfophenyl)phosphonium hydrogen sulfate as catalyst under solvent-free conditions. Good yields, short reaction times, straig...

The main aims of this work were the synthesis and characterization iron(III) complexes with a ditopic ligand H2L consisting bis(salicylidene)isothiosemicarbazide moiety N2O2 binding site crown-ether (O6) moiety. A series high-spin complexes, i.e. [FeIIILClBa(CH3OH)(H2O)0.5(ZnCl4)] (1), [FeIIILCl] (2), [FeIIIL(N3)] (3) [(FeIIIL)2O] (4), synthesized. characterized by mass spectrometry, IR UV-vis ...
