GF 15 is a potent inhibitor of centrosomal clustering in tumor cells.
GF 15 leads to multipolar mitosis induction with an EC50 of 900 nM. GF 15 exhibits potent cytotoxicity in a concentration-dependent manner against a broad spectrum of tumor cell types including colon, cervix, glioblastoma, pancreas, leukemia, and myeloma-derived cell lines with IC50s of 1-5 μM[1].
Treatment of mouse xenograft models of human colon cancer and multiple myeloma with GF 15 results in tumor growth inhibition and significantly prolonged survival[1].
