In February 2013, the US FDA approved pomalidomide (also known as CC4047) for the treatment of multiple myeloma (MM) in patients with disease progression after receiving other cancer therapeutics. Pomalidomide is a 4-amino analog of thalidomide with enhanced potency and an improved toxicity profile. Pomalidomide and thalidomide exert their effects by modulation of immunity, inhibition of angiogenesis, interference with the bone/tumor microenvironment, and inhibition of the cereblon protein. Pomalidomide potently inhibited in vitro proliferation in a variety of human MM cell lines, IC50~10 nM, while thalidomide showed almost no inhibition up to 100 μM. In mouse MM tumor models, 50 mg/kg daily doses of pomalidomide resulted in marked inhibition of tumor growth after 15 days of treatment and complete regression in 3–6 weeks versus thalidomide-treated controls at the same dose. Pomalidomide is prepared by condensation of 4-nitrophthalic anhydride with 3-aminopiperidine-2,6-dione followed by catalytic hydrogenation of the nitro group.
