Sardomozide HCl, also known as SAM486A or CGP48664, is a second-generation polyamine synthesis inhibitor, which inhibits the activity of the polyamine biosynthetic enzyme S-adenosylmethionine decarboxylase (SAMDC). SAM486 is more potent and specific than the first-generation SAMDC inhibitor methylglyoxal (bis) guanylhydrazone (MGBG). Preclinical testing confirmed promising antiproliferative activity. The in vitro tests showed that p53 wild-type NB cells were highly sensitive to SAM486A treatment. Most notably, SAM486A treatment resulted in the rapid accumulation of proapoptotic proteins p53 and Mdm2.

How to use

In Vitro:

Sardomozide is a S-adenosylmethionine decarboxylase (SAMDC) inhibitor with an IC50 of 5 nM in cell assay. Following treatment for 48 h with 3 μM Sardomozide, intracellular SAMDC activity is reduced to 10% of control. When the CHO/664 cells are grown in the presence of Sardomozide and during treatment with DENSPM, vacuole formation is not observed, and these cells are growth-inhibited and contain levels of DENSPM similar to the parental CHO cells.
