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

7beta-OHsitosterol and 7beta-OHcholesterol are natural compounds of plant and animal cells with high structural similarity. Recently it was reported that both compounds induced apoptosis on human colon cancer cells by targeting different signalling pathways. Our study aimed at comparing their

Reduction of cellular polyamine pools results in inhibition of cell proliferation and sometimes in induction of cell death. Reduction of cellular polyamine pools can be achieved by several strategies involving all the mechanisms of polyamine homoeostasis, i.e. biosynthesis, catabolism and

We showed previously that inhibition of polyamine catabolism with the polyamine oxidase inhibitor MDL 72527 (MDL) potentiates the apoptotic effects of apple procyanidins (Pcy) in SW620 cells. Here we report that Pcy caused an activation of the intrinsic apoptotic pathway
