Clostridium difficile is a major nosocomial pathogen responsible for pseudomembranous colitis and many cases of antibiotic-associated diarrhea. Because of potential relapse of disease with current antimicrobial therapy protocols, there is a need for additional and/or alternative antimicrobial agents for the treatment of disease caused by C. difficile. We have synthesized a systematic series of ...

Consumption and production of bismuth compounds are increasing, however, little information on the toxic effects and effective methods in removal of bismuth compounds are available. Although bismuth intoxication is currently rare, a careful evaluation should be carried out for possible exposure. We reported a16-year-old female who developed acute kidney failure, tonsillar ulceration and posteri...

bismuth salts and different antimicrobials including metonidazole & tetracyclines were used in the assessment of inhibition zone of helicobacter pylori cultures on solid media. antibiotics were used or in combined in order to find out their possible synergistic effects. it was showed that: only bismuth substrate and not then salts have antibacterial effects on helicobacter pylori and also on th...

Abstract: Bismuth(III) compounds (BiX3, X = Cl, Br, NO3 and OTf etc.) are moistureand air-tolerant Lewis acids, which have been widely applied as green catalyst in diverse organic synthesis in the past few years. This review illustrates significant advances in this field over recent five years, and mainly focuses on the bismuth-catalyzed formation of carbon-carbon, carbon-nitrogen, carbon-sulfu...

For the last three centuries, Bismuth compounds have been of traditional importance for the treatment of infectious diseases, syphilis, amoebiasis, dyspepsia and diarrhea 1. Despite its old history, intensive research and investigation on the mechanism of action and its clinical efficacy has begun in recent years.Trivalent bismuth preparations such as bismuth subsalicylate (BSS) and colloidal b...

: Bismuth compounds have been used extensively as medicines and in particular for the treatment of gastrointestinal ailments. In addition to bismuth's well known gastroprotective effects and efficacy in treating H. pylori infection it also has broad anti-microbial, anti-leishmanial and anti-cancer properties. Aspects of the biological chemistry of bismuth are discussed and biomolecular targets ...

Six inorganic-organic bismuth 2,6-pyridinedicarboxylate (pdc) compounds, [Bi(2,6-pdc)(3)]·3(dma), 1, [Bi(2,6-pdc)(3)]·3(dma)·2(H(2)O), 2, [Bi(2,6-pdc)(2)(dmf)]·(dma), 3, Bi(2,6-pdc)(2,6-pdcme)(MeOH), 4, [LiBi(2,6-pdc)(3)(H(2)O)]·2(dma), 5, and Li(5)Bi(2,6-pdc)(4)(H(2)O)(2), 6 (where dma = dimethyl ammonium cation, dmf = dimethylformamide and 2,6-pdcme = 6-methyl-oxycarbonyl pyridine 2-carboxyla...

The participation of renal metallothionein (MT) in the toxicity and antitumor activity of cis-diamminedichloroplatinum(II) (cis-DDP) in male mice was examined. Preinduction of MT in the kidney by the s.c. administration of bismuth compounds decreased the lethality and renal and gastrointestinal toxicity caused by a single s.c. injection of cis-DDP. In the present study a correlation between the...
