The understanding of nitric oxide (NO) signaling has grown substantially since the identification of endothelial derived relaxing factor (EDRF). NO has emerged as a ubiquitous signaling molecule involved in diverse physiological and pathological processes. Perhaps the most significant function, independent of EDRF, is that of NO signaling mediated locally in signaling modules rather than relyin...
The biodegradation of hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) in liquid cultures with municipal anaerobic sludge showed that at least two degradation routes were involved in the disappearance of the cyclic nitramine. In one route, RDX was reduced to give the familiar nitroso derivatives hexahydro-1-nitroso-3,5-dinitro-1,3, 5-triazine (MNX) and hexahydro-1,3-dinitroso-5-nitro-1,3,5-triazin...
Cytochrome P-450 and NADPH: cytochrome P-450 reductase were solubilized by detergents from microsomal fraction of tulip bulbs Tulipa fosteriana L. and purified to electrophoretic homogeneity. The purification was achieved by anion-exchange column chromatography, hydroxyapatite-column chromatography and affinity chromatography. The two enzyme showed relative molecular weights of about 54,200 and...
nitrosourea (BCNTJ) is shown in Chart 1. The back ground for the development of the nitrosoureas has been recently reviewed by Schabel et al. (4). Initial interest in the group of compounds of which BCNU is a member was stimulated by the finding of the Cancer Chemotherapy National Service Center screening program that i-methyl i-nitroso-3-nitroguanidine (NSC-9369) had weak activity against i.p....
