Objective: Growing resistance of microorganisms to potent antibiotics has renewed a great interest towards investigating bactericidal properties of nanoparticles and their nanocomposites as an alternative. Therefore, the present study has been carried out to investigate and compare the antibacterial properties of copper (Cu) and zerovalent iron (Feo) nanoparticles. Methods: Nanoparticles were s...

Aryl-substituted olefins react with t-butyl nitrite and sodium borohydride in the presence of iron(ii)phthalocyanine to give oximes in moderate to high yields.

Background Several studies have demonstrated the use of metallic nanomaterials with applications in the biological area with very promising results. Gold nanoparticles (AuNP’s) have attracted great interest from researchers due to its electronic properties, optical, thermal, and its great potential for application in physical, chemical and biological [1]. In general, the AuNP’s are prepared by ...

Boron-10 enriched boric acid, H3B03, was converted to the corresponding sodium borohydride, NaBH4, in essentially quantitative yields, by using slightly modified literature methods involving the formation of butyl borate, (n-OBu)jB, first and then reacting it with NaH in mineral oil. The oxidation reaction of NaBH« with I2 in diglyme and subsequent addition/purification in dioxane gave Na[B3Hg]...

Increased water pollution due to the tremendous increase of dye-containing effluent is still a serious problem which, in turn, adversely affects aquatic life and, consequently, balance our ecosystem. The aim this research was investigate whether Ca-ALG/MgO/Ag nanocomposite beads successfully prepared from calcium alginate hydrogels with MgO (Ca-ALG/MgO) doped Ag nanoparticles (Ag NPs) caused ef...

A convenient one-pot synthesis of 1,2-amino alcohols from -amino acids with retention of optical purity by use of 1,1’-carbonyldiimidazole and sodium borohydride is described.

[formula: see text] 1,3-Dithianes and -dithiepines are prepared via an experimentally simple and efficient direct transformation of 1,n-alkyl dihalides utilizing carbon disulfide and sodium borohydride.

A new Kinetic Spectrophotometic method for the Determination of trace amount Sulfacetamide Drug into real samples has been described based with silver nanoparticles starch-capped sensor, by sodium borohydride. The reaction is followed spectrophotometrically by measuring the decrease in the absorbance at 347.5 nm. 1.0×10-2 molL-1 silver nanoparticles starch-capped sensor, 2.0×10-3 mol L-1 sodium...

Recently we reported on the rapid inactivation of tetracycline by use of cupric-morpholine complex (Kaplan, Lannon, and Buckwalter, J. Pharm. Sci., 64, 163, 1965). This degradation procedure is used as part of an assay technique for kanamycin in the presence of tetracycline. We have since found that sodium borohydride (Metal Hydrides Inc., Beverly, Mass.) can substitute for cupric-morpholine co...

The structures of mercaptan and sodium borohydride reaction products of neocarzinostatin chromophore A (NCS Chrom A) are compared. Implications on the mechanism of activation of NCS are discussed.
