چکیده
In the title Schiff base, C(18)H(22)N(4)O, the hexa-hydro-pyrimidinyl ring adopts a chair conformation. The dihedral angle between the aromatic rings of the 4-(2-phenyl-diazen-yl)phenol unit is 15.7 (1)°. There is an intra-molecular O-H⋯N hydrogen bond between the hydroxyl group and an N atom of the hexa-hydro-pyimidinyl unit. Inter-molecular N-H⋯O and N-H⋯N hydrogen bonds give rise to a layer structure.

The title compound, {[Ag(C(19)H(16)N(8))](CF(3)SO(3))}(n), is a coordin-ation polymer with cationic chain motif. The Ag(+) cation is coordinated by two unsubstituted imidazolyl N atoms of two independent 2-paBIM ligands [2-paBIM is bis-{2-[(E)-phenyl-diazen-yl]-1H-imidazol-1-yl}methane]. The shortest Ag⋯Ag separation in a cationic chain is 8.841 (2) Å and the dihedral angle between two 2-phenyl...

متن کاملIn vitro cytotoxic activity evaluation of phenytoin derivatives against human leukemia cells.
Hydantoin derivatives, including phenytoin (5,5-diphenylhydantoin), have recently gained attention as they possess a variety of important biochemical and pharmacological properties. Nevertheless, available information on anticancer activity of hydantoin derivatives is still scarce. Here, we evaluated possible antileukemic potential of four phenytoin analogs, namely: methyl 2-(2,4-dioxo-5,5-diph...
