A new Schiff base ligand (L) obtained by the condensation reaction of N-acetylaceto-otoluidineand 2-aminopropanoic acid (an amino acid), is used to synthesize four mononuclearcomplexes of [MLCl] and [ML2] types (where M = Cu(II) and Zn(II); L = Schiff base) bykeeping the metal and ligand ratio as 1:1 and 1:2 respectively. This ligand and its complexeshave been characterized on the basis of diff...

Objective(s):Perovskia abrotanoides Kar., from family Lamiaceae, is a little known medicinal plant growing in various regions of Iran. In the present study, cryptotanshinone (CT), tanshinone 2A (Tan2A), and hydroxycryptotanshinone (HCT) were isolated and purified from the roots of P. abrotanoides. In addition, cytotoxic and apoptotic effects of total root extract (TE) and three purified tanshin...

A new Schiff base ligands (H2L -H2L 3) was synthesized by the condensation reaction of 4-acyl pyrazolones and 2-benzothiazolyl thiosemicarbazide. The ruthenium(II) Schiff base complexes were prepared by the interaction of the ligands with [RuHCl(CO)(EPh3)2(B)] (E=P/As; B=PPh3/AsPh3/py). They were characterized by elemental analysis, IR, UV-vis, 1H, 13C, and 31P NMR spectral data. The interactio...

few novel cobalt(ii) and copper(ii) complexes [m(fmp)3]cl2, [m(fmp)(bpy)2]cl2,[m(fmp)(phen)2]cl2 and [m(fmp)(phen)(bpy)]cl2 (fmp = 3-furan-2-ylmethylene-pentane-2,4-dione, phen = 1,10-phenanthroline, bpy = 2,2'-bipyridine) have been synthesized andcharacterized by elemental analyses, molar conductance, magnetic susceptibility measurements,ir, electronic, epr, mass spectra and cyclic voltam...
