This paper reports on the cytotoxic effect induced by a new natural steroidal saponin, icogenin, on the myeloid leukemia cell line HL-60. Icogenin was found to be a cytotoxic compound IC(50) 2.6+/-0.9microM at 72h, with growth inhibition caused by the induction of apoptosis, as determined by microscopy of nuclear changes and the fragmentation of poly(ADP-ribose) polymerase-1.
