Insight Into

Growing demand for safe foods coupled with the intent to reduce food waste, seeing as much of it is lost through contamination by spoilage microorganisms, leads to research on antimicrobial agents such as LAE (Nα-lauroyl-L-arginine ethyl ester monohydrochloride). This compound has great antimicrobial potential against a range of microorganisms and, therefore, its use may be of extreme importance for the food industry in the search for antimicrobial agents with a broad spectrum of action. Thus, the objective of this article is to review the research involving LAE, when studied in vitro, in vivo and in the incorporation in different packaging in order to be released in a controlled manner for food products. In conclusion, despite the fact that it has a strong antimicrobial activity, it is still little known and is not accepted in all countries, including Brazil. With greater insight into this antimicrobial agent, more countries could use it, supporting worldwide in food preservation.

Didecyldimethylammonium Chloride

In commercial products such as household deodorants or biocides, didecyldimethylammonium chloride (DDAC) often serves as an antimicrobial agent, citral serves as a fragrance agent, and the excipient ethylene glycol (EG) is used to dissolve the active ingredients. The skin sensitization (SS) potentials of each of these substances are still being debated. Moreover, mixtures of DDAC or citral with EG have not been evaluated for SS potency. The in vitro alternative assay called human Cell Line Activation Test (h-CLAT) and Direct Peptide Reactivity Assay (DPRA) served to address these issues. On three independent runs of h-CLAT, DDAC and citral were predicted to be sensitizers while EG was predicted to be a non-sensitizer and also by the DPRA. Mixtures of DDAC or citral with EG at ratios of 7:3 and 1:4 w/v were all positive by the h-CLAT in terms of SS potential but SS potency was mitigated as the proportion of EG increased. Citral and its EG mixtures were all positive but DDAC and its EG mixtures were all negative by the DPRA, indicating that the DPRA method is not suitable for chemicals with pro-hapten characteristics. Since humans can be occupationally or environmentally exposed to mixtures of excipients with active ingredients, the present study may give insights into further investigations of the SS potentials of various chemical mixtures.

This study evaluated the in vitro activity of A-86719.1, a novel 2-pyridone antimicrobial agent. The drug inhibited all tested members of the family Enterobacteriaceae at < or = 0.5 microgram/ml and all tested Pseudomonas aeruginosa, Burkholderia (Pseudomonas) cepacia, and Xanthomonas maltophilia strains at < or = 2 micrograms/ml. All but two strains of gram-positive bacteria were inhibited by < or = 1 microgram of the new drug per ml, including isolates highly resistant to ciprofloxacin.
