✦ Synopsis

Selected synthetic oligoamines were able to inhibit (ICso) the growth of leukemic L 1210cells in concentrations between4-10 J.1rnollL TIle essential structural features were at least two basic nitrogen functions in suitable distance, substituted with arylalkyl or alkyl groups. TIle favorable chain length is about eight carbon atoms. TIle cytostaticeffect is complete after 30 min and cannot be washed out with buffer. Viability measurements showed that the leukemic cells were killed in a time dependent manner. As no influence on the cell nucleuscould be observed this is most probably due to interaction with the cell membrane. When high local concentrations are applied in vivo. the oligoamines are toxic because of cytolytic properties. This toxicity can be overcome by administration of suitable prodrugs (lDSO > 1000mg/kg).
