Homologous dialkanesulfonic esters of 2,2'-iminodiethanol, 3,3'-iminodi-1-propanol, N-(2-hydroxyethyl)-6-amino-1-hexanol, and N-(3-hydroxypropyl)-6-amino-1-hexanol were prepared via the N-trityl derivatives and screened for L1210 activity. For each active agent significant increases in life-span in L1210 tests (ILS) were correlated by linear least-squares regression with the corresponding log doses
