We recently confirmed that ciclopirox olamine inhibits Wnt/beta catenin signalling in myeloma. Griseofulvin (GF) has similar chemical features as compared to ciclopirox olamine. In this study the anti-tumor effect of GF was investigated. GF demonstrated a major apoptotic activity in various human and murine myeloma and lymphoma cell lines as well as in human primary cells. In vivo, tumor growth as well as overall survival were significantly reduced in mice treated with GF as compared to untreated mice. In conclusion, our results reveal a significant selective induction of apoptosis by GF and suggest a significant in vivo effect against myeloma.
