Antileukemic Agents. II. New 2, 5-Bis (1-aziridinyl)-p-benzoquinone Derivatives

A series of 2, 5-bis (1-aziridinyl)-p-benzoquinone derivatives were synthesized and evaluated as antileukemic agents. The most active compounds against lymphoid leukemia L-1210 in BDF1 mice were 2, 5-bis (1-aziridinyl)-3-(2-carbamoyloxyethyl-1-methoxy)-6-methyl-p-benzoquinone, carbazilquinone (7), and related compounds (8, 23 and 24). Structure-activity relationships were discussed.
