Abstract

We have developed a procedure for the synthesis of N-hydroxy-N(1)-phenyloctanediamide (suberoylanilide hydroxamic acid (SAHA)), providing the product in 79.8% yield. SAHA is a potent inhibitor of histone deacetylase, induces differentiation and/or apoptosis in certain transformed cells in culture, and suppressed the growth of human prostate cancer LNCaP and PC-3 cell lines. The combination of SAHA with other compounds inhibited cell proliferation of LNCaP cells in additive fashion and resulted in synergistic growth inhibition.
