A DT-diaphorase responsive theranostic prodrug for diagnosis, drug release monitoring and therapy.
A DT-diaphorase-activatable theranostic prodrug, which contains camptothecin, a self-immolative linker and a trigger group, has been developed for the detection of DT-diaphorase, tracking of drug release and selectively killing cancer cells over-expressed with DT-diaphorase. This strategy may offer a new approach for the development of enzyme-catalyzed theranostic anticancer therapeutics.
متن کاملProperties and reaction mechanism of DT diaphorase from rat liver.
DT diaphorase was purified to homogeneity from rat liver and characterized. The molecular weight of the enzyme was calculated to be 5.0 h 0.06 x lo4 from sedimentation equilibrium experiments and to be 4.8 x IO4 by thin layer gel filtration method using Sephadex G-200. The identity of FAD as a prosthetic group was confirmed by o-amino acid oxidase test. It was found that 1 mole of FAD was prese...
متن کاملCell-selective metabolic labeling of proteins.
Metabolic labeling of proteins with the methionine surrogate azidonorleucine can be targeted exclusively to specified cells through expression of a mutant methionyl-tRNA synthetase (MetRS). In complex cellular mixtures, proteins made in cells that express the mutant synthetase can be tagged with affinity reagents (for detection or enrichment) or fluorescent dyes (for imaging). Proteins made in ...
متن کاملExpression in Human Non-Small Cell Lung Carcinoma Cigarette Smoking Is a Determinant of DT-Diaphorase Gene
The levels of NAI)(P)H:(quinone-acceptor) oxidoreductase (EC.1.6. 99.2) (DT-diaphorase) mRNA and enzyme activity have been studied in paired human normal lung and non-small cell lung tumor samples from patients with a history of cigarette smoking. There were significantly higher levels of DT-diaphorase mRNA (1.2 kilobases) in lung tumor com pared to normal lung tissue of patients who had stoppe...
متن کاملCigarette smoking is a determinant of DT-diaphorase gene expression in human non-small cell lung carcinoma.
The levels of NAD(P)H:(quinone-acceptor) oxidoreductase (EC.1.6.99.2) (DT-diaphorase) mRNA and enzyme activity have been studied in paired human normal lung and non-small cell lung tumor samples from patients with a history of cigarette smoking. There were significantly higher levels of DT-diaphorase mRNA (1.2 kilobases) in lung tumor compared to normal lung tissue of patients who had stopped s...
