Three types of 1-chloromethyl-5-hydroxy-1,2-dihydro-3H-benz[e]indole (seco-CBI) dimers were designed, synthesized and evaluated in vitro by NCI against nine types of cancer cells. Biological results showed that the antitumor activities of these seco-CBI dimers were strongly related to the position and length of the linker and generally with potency increasing in the order of C7-C7 dimers (22i-iv) < C7-N3 dimers (28i-iv) < N3-N3 dimers (25i-iv). Compound 28iv showed significant activity against CCRT-CEM, HL-60 (TB), MOLT-4, and SR leukemia cell lines and the MCF 7 breast cancer cell line with GI(50) values < 0.01 mu M. N3-N3 dimer 25i displayed striking potency against leukemia, CNS cancer, melanoma and prostate cancer cell lines with GI(50) values < 0.01 mu M against all the cell lines and showed the highest overall potency of the agents examined (GMG = 0.0120 mu M).
