Reduction of the nitroso group in streptozotocin (1a) has led to cyclized products rather than a semicarbazide (1c). Some analogs (1e, 9a, 9b, 9c and 9d) of streptozotocin in which the nitroso group was replaced by other groups have been prepared.
BACKGROUND S-nitrosation--the formation of S-nitrosothiols (RSNOs) at cysteine residues in proteins--is a posttranslational modification involved in signal transduction and nitric oxide (NO) transport. Recent studies would also suggest the formation of N-nitrosamines (RNNOs) in proteins in vivo, although their biological significance remains obscure. In this study, we characterized a redox-base...
one of the applications of nanotechnology is use of carbon nanotubes for the targeted delivery of drug molecules. to demonstrate the physical and chemical properties of biomolecules and identify new material of drug properties, the interaction of carbon nanotubes (cnts) with biomolecules is a subject of many investigations. cnts is a synthetic compound with extraordinary mechanical, thermal, el...
Abstract In this study, we investigated the influence of O 2 , SO and NO x on branched linear polyethyleneimine (PEI) functional silica CO adsorbents (BPEI-SiO LPEI-SiO respectively). was much more likely to oxidize BPEI-SiO compared with form C=O C=N groups led a 23.0% decrease in adsorption capacity after 990 min cumulative contact 10% . contrast, lost only approximately 3.6% its capacity, al...
Aim. To study the frequency and spectrum of cytogenetic disorders in Triticum aestivum L., induced by effect moderate high concentrations N-nitroso-N-methylurea. Methods. The seeds winter wheat cultivars Albatros odeskyi Zymoiarka were treated with water solution N-nitroso-N-methylurea such as 0.005 %, 0.01 0.025 %. A analysis cells a root meristem was made help an anatelophase method. Results....
