BACKGROUND Curcumin and vanillin are the two useful compounds in food and medicine. Bismuth nitrate pentahydrate is an economical and ecofriendly reagent. METHOD Bismuth nitrate pentahydrate impregnated montmorillonite KSF clay and curcumin were subjected to microwave irradiation. RESULTS Microwave-induced bismuth nitrate-promoted synthesis of vanillin from curcumin has been accomplished in...

background and objectives: pseudomonas aeruginosa is an opportunistic pathogen that can produce biofilm. biofilm is a complex, three dimensional structure in which microorganisms are attached to a surface and embedded in a matrix made of extracellular polymers. due to high resistance to antimicrobial agents, biofilms create difficulties in various situations in healthcare. in this study, antibi...

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...

BACKGROUND Eugenol, the main constituent of clove oil possesses a number of medicinal activities. To enhance the medicinal property, structural modification is required. On the other hand, bismuth nitrate pentahydrate has been established as an excellent eco-friendly nitrating agent for several classes of organic compounds. RESULTS Bismuth nitrate pentahydrate-induced nitration of eugenol has...

Uniform bismuth nanospheres were successfully prepared from bismuth nitrate in the presence of poly(N-vinyl-2-pyrrolidone) (PVP) by solvothermal process. The product was characterized by powder X-ray diffraction, scanning electron microscopy, transmission electron microscopy, selected area electron diffraction, and energy-dispersive X-ray. PVP plays a critical role both as a reducing agent and ...

Montmorillonite impregnated with bismuth nitrate has been found to be an excellent reagent for the synthesis of several nitro compounds of biological significance in high yield.

Nitro catechols via 2 hydroxyl group and a nitro group have a wide range of functions including reagents form stable complexes with more than 40 elements in the fields of analytical chemistry, biochemistry, coordination chemistry, environmental chemistry, atrium exploration, organic chemistry, pharmacy, etc. Moreover, the nitro to amine recovery has a potential function in different fields. In ...

The participation of renal metallothionein (Ml) in the toxicity and antitumor activity of cii-diamminedichloroplatinum(II) (cw-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 c/j-DDP. In the present study a correlation between the ...
