CAS#: 138794-73-7 (HCl)

Description: 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.
