It is mainly used as a germicidal disinfectant. The killing rate of heterotrophic bacteria, iron bacteria and sulfate-reducing vaccine was better than that of dodecyldimethylbenzyl ammonium chloride, dodecyl dimethyl benzyl ammonium bromide and other commonly used quaternary ammonium salt bactericides, it...
The in vitro assessment of the antitumorigenic activities related to the studied compounds was undertaken using the 3-(4,5-dimethylthiazol-2yl)-2,5-diphenyl tetrazolium bromide (MTT) colorimetric assay, as previously reported [32]. The compounds under investigation were tested in three triplicates...
