The decomposition rate increases with increasing pH value of the medium. The found reversibility of the reactions of phenylhydrazonopropanedinitriles with thiols is discussed with respect to elucidation of bioactivity of phenylhydrazonopropanedinitriles.

Abstract:

Several new 2,6-bis(substituted)pyridine ligands and 2,6-bis(substituted)pyridine Ag(I) nitrate complexes were synthesized and characterized spectroscopically. The newly synthesized ligands include pyridine-2,6-bis(3-oxopropanenitrile) (1), pyridine-2,6-bis(2-cyano-N-phenyl-3-oxopropanethioamide) (2), and pyridine-2,6-bis((E)-2-(2-phenylhydrazono)-3-oxopropanenitrile) (3). The newly synthesized ligands and silver(I) complexes were evaluated for their in vitro anticancer activity against four human cancer cell lines including hepatocellular carcinoma (HePG2), lung adenocarcinoma (A549), colon c

Abstract:

The title compound, [RuCl2(C15H13N3O2)(C10H8N2)]·CH2Cl2, has a pseudo-octahedral coordination environment made up of two trans chloride ligands and four N-donor atoms, two of which belong to the azoimine bidentate ligand and two to the bipyridyl molecule. The ester group is disordered over two positions; the site occupancy factors are ca 0.6 and 0.4.

Abstract:

Glyoxalbis(phenylhydrazone) 1a reacts with aromatic aldehydes and secondary amines to yield either propan-1,2-dialdiphenylhydrazones 2 or arylazopyrazoles 7 depending on the nature of utilised aldehyde. The reactivity of 1a with phosphorus oxychloride (POCl3) and dimethylformamide (DMF) (Vilsmeier reaction) afforded the cinnolin-3-carbaldehyde phenylhydrazone 11. Compound 1a afforded also the tribenzoyl derivative 16 on treatment with benzoyl chloride. Only the diacetyl derivative 17 was produced on refluxing 1a in acetic anhydride. The diphenylhydrazone 20 was produced on treatment of 19, pre

Abstract:

Recently, heterocyclic compounds and amino acids are of great interest to researchers owing to their various biological activities like; antimicrobial, anticancer, antiviral, anti-inflammatory, etc. Isatin is also a vital moiety containing N and O donor heteroatoms, and its Schiff base is used for complexation with metal ions which may alter their activities. The new metal complex of Ni has been synthesized using two ligands, 3-(2-phenylhydrazono) indolin-2-one (PHI) (L1) and amino acid Histidine (L2). The newly prepared ligand and the complex are further characterized by determination of mole

The resulting complexes have been characterized by elemental analyses, molar conductivity, spectral data (IR, 1H NMR, mass) and magnetic moments. Furthermore, the ligands and their metal complexes have been screened for their cytotoxicity against different
