Antibacterial activity of soluble pyridinium-type polymers.

Antibacterial/Antiviral Property and Mechanism of Dual-Functional Quaternized Pyridinium-type Copolymer

Due to the massive outbreaks of pathogen-caused diseases and the increase of drug-resistant pathogens, there is a particular interest in the development of novel disinfection agents with broad-spectrum antipathogenic activity. In the present study, water-soluble pyridinium-type polyvinylpyrrolidones with different counter anions were prepared. Structural characterization was conducted via 13C–1...

Poly(pyridinium phenylene)s: water-soluble N-type polymers.

Poly(pyridinium phenylene) conjugated polymers are synthesized by a cross-coupling and cyclization sequence. These polyelectrolytes are freely soluble in water and display high degrees of electroactivity. When reduced (n-doped) these materials display in situ conductivities as high as 160 S/cm. The high conductivity is attributed to the planar structure that is enforced by the cyclic structures...

Effect of herbal supplements of caraway (Carum carvi) and fenugreek (Trigonella foenum graecum) on antibacterial activity and soluble protein of mucus in Cyprinus carpio fingerlings

In this study, we investigated the effects of herbal supplements of Carum carvi and Trigonella foenum graecum on soluble protein and antibacterial activity of mucus in common carp (Cyprinus carpio) fingerlings. Fish with a mean weight of 2.457±0.057 g were divided randomly into 7 treatments (one control group and the experimental groups treated with diets that contained different percents of ca...

Antibacterial and hemolytic activities of pyridinium polymers as a function of the spatial relationship between the positive charge and the pendant alkyl tail.

Antimicrobial and Antifungal Effects of Acid and Water-Soluble Chitosan Extracted from Indian Shrimp (Fenneropenaeus indicus) Shell

Background & Objective : Currently, efforts are underway to seek new and effective antimicrobial agents, and marine resources are potent candidates for this aim. The following study was conducted to investigate the efficacy of water-soluble and acid-soluble chitosan against some pathogenic organisms.   Materials & Method s: Inhibition zone of different concentrations (5, 7.5, and 10 mg/ml) of a...
