lanthanide(iii) chloro complexes of 4[n-(4’-hydroxy-3’-methoxybenzalidene) amino] antipyrine semicarbazone (hmbaaps) (i) and 4[n-(3’,4’,5’-trimethoxybenzalidene) amino] antipyrine semicarbazone (tmbaaps) (ii) with the general composition lncl3.2l (ln = la, pr, nd, sm, gd, tb, dy or ho; l = hmbaaps or tmbaaps) are reported. all the complexes were synthesized in ethanolic medium and refluxed the ...

Simplicial complexes are discrete representations of topological spaces that are practical for computational studies. The first three Betti-numbers (indicating the number of components, tunnels and voids), as well as the topological persistence of each such feature, is welldefined and can be efficiently computed for simplicial complexes embedded in 2D and 3D [1, 2]. We introduce a novel represe...

Complexes of the Bowman-Birk soybean inhibitor with either trypsin or chymotrypsin and with both of these enzymes were isolated by gel atration. Amino acid analyses and molecular weight estimates by gel filtration were consistent with the formation of a 1: 1 molar complex between inhibitor and trypsin or chymotrypsin and a 1: 1: 1 molar complex composed of inhibitor, trypsin, and chymotrypsin. ...

Ibuprofen a non-steroidal anti-inflammatory drug (NSAID) is among the most prescribed drug on the world. Copper(II) complexes with NSAIDs are more active than their parent drugs and exhibit a lower toxicity than inorganic forms of copper [1] . Further, many of these complexes, including that of copper ibuprofenate complex, have a better anti-ulcer protective effect than the parent drugs. Binary...

Bis(oxazoline) copper(II) complexes 1±3 function as enantioselective Lewis acid catalysts for carbocyclic and hetero Diels±Alder, aldol, Michael, ene, and amination reactions with substrates capable of chelation. X-ray crystallography of the catalyst reveals a propensity for the formation of distorted square planar or square pyramidal complexes. The sense of asymmetric induction is identical fo...
