MDL 72527is an inhibitor of polyamine oxidase (spermine oxidase SMO).
MDL 72527is an inhibitor of polyamine oxidase (spermine oxidase SMO). It blocks the production of H2O2 and increases the cells survival. Polyamine catabolism is one of the major causes of the ROS production of prostate cells in general and androgen-induced enhancement of ROS in androgen-dependent CaP cells in particular. Reports suggest that androgen stimulation of prostate cancer results in accumulation of ROS, which lead to progression of cancer, such progression is control by MDL 72527.

Apple procyanidins have chemopreventive properties in a model of colon cancer, they affect intracellular signalling pathways, and trigger apoptosis in a human adenocarcinoma-derived metastatic cell line (SW620). In the present study we investigated relationships between procyanidin-induced alterations in polyamine metabolism

Murine N(1)-acetylated polyamine oxidase (mPAO) was treated with N,N'-bis-(prop-2-ynyl)-1,4-diaminobutane, a poor substrate and inhibitor for the enzyme, with K(m) and K(i) values in the millimolar range. Apparently, its oxidation produces prop-2-ynal, which reacts with amino acyl nucleophiles. Using a steady-state

MDL 72527 was considered a selective inhibitor of FAD-dependent polyamine oxidases. In the present communication, we demonstrate that MDL 72527 inactivates bovine serum amine oxidase, a copper-containing, TPQ-enzyme, time-dependently at 25 degrees C. In striking contrast, the enzyme remained active

Spermine oxidase (SMO) is a recently described flavoenzyme belonging to the class of polyamine oxidases (PAOs) and participating in the polyamine metabolism in animal cells. In this paper we describe the expression, purification, and characterization of the catalytic properties of

In a previous work, we identified a Cys(2)/His(2)-type zinc-finger transcription repressor, (ZFT1), that functions in a spermine-mediated signal transduction pathway in tobacco plants. Database search disclosed the presence of another Cys(2)/His(2)-type zinc-finger protein ZFP1 (accession number AAC06243) in tobacco plants.
