1,2-Epoxy alkanes from C3 to C8 were reacted with DNA, deoxyguanosine and 4-(p-nitrobenzyl) pyridine (NBP). DNA was hydrolyzed at neutral pH to release 7-alkylguanines. The products were analyzed by HPLC. The epoxides reacted largely according to the chain length, shorter

We developed a rapid and simple method for identifying 25 commonly used organophosphorus insecticides in human serum using high-performance thin-layer chromatography (HPTLC). These organophosphates were separated on plates with three different developing systems within 6-18 min and detected by means

On-resin real-time monitoring by a combination of a color test of (p-nitrobenzyl)pyridine and Disperse Red was developed for oligosaccharide synthesis.
Mitomycin C (MC) requires bioreduction prior to the generation of alkylating moieties. NADPH-cytochrome P450 reductase is predominant in metabolic activation of MC in hypoxic cancer cells. In this study, neuronal nitric oxide synthase (nNOS), whose reductase domain is structurally similar

The chemical reactivity of the mutagenic epoxides (EP) propylene oxide (PO), 1,2-epoxybutane (1,2-EB), and cis- and trans-2,3-epoxybutane (cis- and trans-2,3-EB) with 4-(p-nitrobenzyl)pyridine (NBP), a bionucleophile model for S(N)2 alkylating agents with high affinity for the guanine-N7 position, was investigated kinetically.
