The asymmetric unit of the title compound, 7C(10)H(8)N(2)·4C(10)H(13)N(3)O(2)S·2H(2)O, contains two independent 2,4-hydroxy-benzaldehyde 4-ethyl-thio-semicarbazone mol-ecules, three and a half 4,4'-bipyridine mol-ecules and one water mol-ecule. Two of the 4,4'-bipyridine mol-ecules lie on general positions and the other three on centers of inversion. The two 4,4'-bipyridine mol-ecules on genera...

The search for better antimicrobial agent due to rapid appearance of multidrug resistant microorganism and antimicrobial properties of semicarbazones and 2,5-disubstituted 1,3,4-oxadiazoles prompted us to undertake the synthesis of a few novel N-[5-(4-substitutedphenyl)-1,3,4-oxadiazol-2-yl]-N-(4substitutedbenzaldehyde)-semicarbazone and N-[5-(4-substitutedphenyl)-1,3,4-oxadiazol-2-yl]-N-[1-(4s...

hexamethylenetetramine-bromine on wet alumina rapidly regenerates carbonyl compounds from their corresponding semicarbazone using microwave under solventless system.

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 ...

o-xylylenebis (triphenylphosphonium peroxymonosulfate) (1) was easily prepared from an aqueous solution of oxone and o-xylylenebis- (triphenylphosphonium bromide). this compound (1) is a useful and selective reagent for conversion of oximes, semicarbazones and phenylhydrazones to the corresponding carbonyl compounds. the reaction was carried out under solvent-free conditions and in the presence...

In the title 1-alkyl-isatin 3-thio-semicarbazone, C(19)H(28)N(4)OS, the imine C=N bond has a Z configuration, whereas the N-N-C=S unit has an E conformation. In the crystal, mol-ecules are connected by N-H⋯O hydrogen bonds, forming zigzag chains running along the b axis.

Three newly synthesized copper complexes with pyridoxal semicarbazone (PLSC), as ligand, after being subjected to biological tests, showed anticancer activity. As ligand PLSC is biologically active, the results of biological activity are as expected. Specifically, an activity was demonstrated in breast cancer cells (MCF7 and MDA MB 231) and proliferative cells (MCF7).
