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.

The Ni-B-P alloy coatings were made autocatalytically (electroless) using an alkaline plating bath with nickel chloride hexahydrate (NiCl2.6H2O) as the source of nickel ions, sodium borohydride (NaBH4) and sodium hypophosphite (NaH2PO2) as reducing agents and source of boron and phosphorous ions, respectively. The effects of bath concentrations on the plating rate, composition of coating, surfa...

The ring opening of some phthalimide derivatives with sodium borohydride in methanol/water (6:1) afforded the corresponding 2-hydroxymethylbenzamides irrespective of the substituents. The most active members of the series evaluated for anti-inflammatory and analgesic activities were 2-hydroxymethyl-N-[4-(2-methoxyphenyl)-piperazin-1-yl]-ethylbenzamide (3d) and 2-hydroxymethyl-N-[4-(2-methoxyphe...

In this study we evaluated two different 99mTc-labeling techniques to produce 99mTc-low density lipoprotein (99mTc-LDL) suitable for the scintigraphic delineation of experimental atherosclerotic lesions. The two methods are 1) a procedure that uses stannous chloride and sodium borohydride (borohydride method) and 2) a procedure that uses sodium dithionite as a reducing agent and that has been s...

Figure 2. Raman spectra of Mg(BH(D)4)2 (in red) and LiBH(D)4 (in blue). Upper curves: deuteride, lower curves: hydride. The asterisk indicates a band resulting from residual diethyl-ether. Figure 5. Structure of Mg(BH4)2 viewed along the hexagonal b axis, showing two unit cells. Red (partially transparent) tetrahedra are BH4units; Mg atoms in blue. Considering the cations as A and the tetrahedr...

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...
