Background:

Perifosine is an inhibitor of Akt [1].

Perifosine is a synthetic antitumor alkylphospholipid. It induces cell apoptosis through inhibiting the activity of Akt. Perifosine shows antitumor activity in various cell lines including NSCLC, MM, epithelial carcinoma, prostate carcinoma and leukemia cells. In H460 cells, perifosine decreased cell survival and induced apoptosis with IC50 values of 1μM and 10 μM, respectively. The treatment of perifosine was also found to induce cleavage of caspase-8, caspase-9, caspase-3 and PARP in this cell line. In MM.1S cells, perifosine induced sub-G1 phase population increase from 15% to 57% at 10 μM and induced cleavage of caspase-8, caspase-9 and PARP in a dose-dependent manner. In mice inoculated with MM.1S cells, oral administration of perifosine significantly reduced MM tumor growth and increased survival [1, 2].
