Crystal structure of diethyl [(4-chloro-anilino)(4-hy-droxy-phen-yl)meth-yl]phospho-nate N,N-di-methyl-formamide monosolvate.

In the title compound, C17H21ClNO4P·C3H7NO, the dihedral angle formed by the aromatic rings is 83.98 (7)°. In the crystal, O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into double layers parallel to (011).

Aqua-(pyridine-3-carb-oxy-lic acid-κN)(pyridine-2,6-dicarboxyl-ato-κO,N,O)copper(II) monohydrate.

In the title Cu(II) complex, [Cu(C(7)H(3)NO(4))(C(6)H(5)NO(2))(H(2)O)]·H(2)O, the environment of the Cu(2+) ion is a distorted square pyramid with the axial site occupied by the O atom from the coordinated water mol-ecule and the square base formed by two O and two N atoms from the tridentate anion and the neutral monodentate pyridine-3-carboxylic acid ligand. O-H⋯O hydrogen bonds, as well as π-π inter-actions [centroid-centroid distance = 3.945 (3) Å] contribute to the stabilization of this structure.

Restoration of DLC1 gene inhibits proliferation and migration of human colon cancer HT29 cells.

DLC1 (deleted in liver cancer-1) is a new candidate tumor suppressor gene, which is inactive in various types of human cancers including colon cancer. To study the function of DLC1, we constructed a pcDNA3.1 vector containing the DLC1 gene and transfected it into HT29 colon cancer cells that were deficient in DLC1 expression.

2-(Hydrazonomethyl)phenol.

The conformation of the title compound, C(7)H(8)N(2)O, is stabilized by an intra-molecular O-H⋯N hydrogen bond. The crystal structure shows inter-molecular N-H⋯O hydrogen bonds.
