Accepted November 9, 2012 A reliable, selective and sensitive LC-MS/MS assay has been proposed for the determination of nitrofurantoin in human plasma. The analyte and nitrofurazone were extracted from 100 μL of human plasma via SPE on Strata-X 33 μm extraction cartridges. Chromatography was done on a BDS Hypersil C18 (100 mm × 4.6 mm, 5 μm) column under isocratic conditions. Quantitation was d...

A new antimicrobial nitrofuran designated SQ 18,506 showed some therapeutic activity when administered orally to mice infected with Escherichia coli, Salmonella schottmuelleri, Shigella flexneri, or Klebsiella pneumoniae. Animals infected parenterally with Streptococcus pyogenes, Proteus mirabilis, Mycobacterium tuberculosis, and Candida albicans, or topically with Trichophyton mentagrophytes, ...

The mechanisms for the development and spread of antibacterial resistance (ABR) in bacteria residing in environmental compartments, including the marine environment, are far from understood. The objective of this study was to examine the ABR rates in Escherichia coli and other Enterobacteriaceae isolates obtained from marine bivalve mollusks collected along the Norwegian coast during a period f...

The so-called " serotonin syndrome " (SS) is a potentially serious condition of central and peripheral serotonergic hyperstimulation. It is caused by the administration of single drugs or combinations of drugs that elevate synaptic levels of serotonin. It can arise following both therapeutic doses and overdoses, while the most serious cases are usually caused by an unintended synergism between ...

Nearly 90 million people (about a quarter of the Latin American population) live in zones where Chagas disease is endemic while 18-20 million are already infected with is causative agent, Trypanosoma (Schizotrypanum) cruzi. It is estimated that there are currently >550,000 new cases and 50,000 deaths associated to this condition every year (Docampo & Schmuñis 1997). This disease leads to an ann...

We have studied the in vivo activity of the new experimental triazole derivative SCH 56592 (posaconazole) against a variety of strains of the protozoan parasite Trypanosoma (Schizotrypanum) cruzi, the causative agent of Chagas' disease, in both immunocompetent and immunosuppressed murine hosts. The T. cruzi strains used in the study were previously characterized as susceptible (CL), partially r...

Background: Antimicrobial resistance (AMR) in bacteria is an increasing health concern. The spread of AMR bacteria (AMRB) between animals and humans via the food chain and the exchange of AMR genes requires holistic approaches for risk mitigation. The AMRB exposure of humans via food is currently only poorly understood leaving an important gap for intervention design. Method: This study aimed t...

Aq4{5-Nitro-2-furyl)-2-thiazolyl]acetamide (NFTA), fed to female Swiss mice at doses of 0.05 and 0.1% of the diet, induced a high incidence of lymphocytic leukemia and a low incidence of forestomach tumors. Several other chemicals structurally related to NFTA were also fed to female Swiss mice to determine structure-activity relationships with respect to organ specificity. 7V-[4-(5-Nitro-2-fury...

1,3,4-oxadiazoles are interesting compounds because of their valuable biological effects such as cytotoxic, antibacterial, antifungal, and anti-tubercular activities. Ethyl mandelate was treated with hydrazine hydrate to yield the corresponding acylhydrazide. Some of the 2,5 disubstituted 1,3,4-oxadiazole derivatives were prepared from acylhydrazide using three different procedures. In the firs...
