Herein, we discuss the synthesis, structural and spectroscopic characterization, biological activity of five heteroligand copper(II) complexes with diethylnicotinamide various fenamates, as follows: flufenamate (fluf), niflumate (nifl), tolfenamate (tolf), clonixinate (clon), mefenamate (mef) N, N-diethylnicotinamide (dena). The composition: [Cu(fluf)2(dena)2(H2O)2] (1), [Cu(nifl)2(dena)2] (2),...

In the crystal structure of the title Co(II) complex, [Co(C(8)H(5)O(3))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], the metal centre is located on an inversion center and is coordinated by two 4-formyl-benzoate (FOB), two diethyl-nicotinamide (DENA) ligands and two water mol-ecules in a slightly distorted CoO(4)N(2) octa-hedral geometry. In the crystal structure, O-H⋯O hydrogen bonds link the mol-ecules...

The chlorinated hydrocarbons chloroform (CHCl3), 1,1-dichlorethane (1,1-DCE) and 1,2-dichloroethane (1,2-DCE) have been detected in finished drinking water. When administered to B6C3F1 mice by gavage in corn oil, these compounds have been shown to induce hepatic tumors. The present study examines the effect on liver tumor incidence of continuous treatment of CHCl3 (600 mg/L and 1800 mg/L), 1,1-...

By-products of disinfection were tested for initiating and/or promoting activity in rat liver by using the rat liver foci bioassay. The assay uses an increased incidence of gamma-glutamyltranspeptidase-positive foci (GGT foci) as an indicator of carcinogenicity. The by-products of disinfection, including chloramine, halogenated humic acids, halogenated ethanes, halogenated acetonitriles, haloge...

Liver cancer (LC) is generally characterized by malignant cell proliferation and growth; it normally develops in stages that progress from non-specific injury of the liver to liver fibrosis, liver cirrhosis, dysplasia nodules, and liver carcinoma. We used a rat model of diethylnitrosamine (DENA)-induced LC; a Rat Genome 230 2.0 Array was used to detect gene expression profile of liver tis...

In the monomeric title complex, [Mn(C(7)H(4)ClO(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], the Mn(II) atom is located on a crystallographic centre of inversion. The asymmetric unit contains one 2-chloro-benzoate (CB) ligand, one diethyl-nicotinamide (DENA) ligand and one coordinated water mol-ecule, all ligands being monodentate. The four O atoms in the equatorial plane around the Mn atom form a sl...

Hepatocellular carcinoma (HCC) is a serious healthcare problem worldwide because of its increasing morbidity and high mortality rates. However, our understanding of the mechanism of liver tumorigenesis remains incomplete. We report the expression of myosin light chain kinase (MLCK) in the livers of rats with diethylnitrosamine (DENA)-induced HCC and investigated the correlation between MLCK an...
