The anticancer properties of Scolopendra subspinipes mutilans extract were investigated. The extract from S. subspinipes mutilans by 80% EtOH was fractionated with n-hexane, dichloromethan ($CH_2Cl_2$), ethylacetate (EtOAc), and butanol (BuOH) in order. The EtOAc fraction showed the highest inhibitory activity (about 80%) against human leukemia (HL-60) cell growth at $50\;{\mu}g/mL$. To explore the mechanism of cytotoxicity, we used several measures of apoptosis to determine whether these processes were involved in EtOAc fraction-induced HL-60 cell death. Our results showed EtOAc fraction induced cell shrinkage, cell membrane blebbing, apoptotic body, and DNA fragmentation. The EtOAc fraction gradually decreased the expression of anti-apoptotic Bcl-xL and led to the activation of caspase-3, -9 and cleavage of PARP. These findings suggest that S. subspinipes mutilans exhibits potential anticancer properties.
