The synthesis of pyrrolo[2,3-e]indole derivatives with the structural characteristics of DNA bis- and mono-intercalators are described. A dihydro benzoindol analogue was also synthesised to elucidate the major structural requirements for cytotoxic activity. A biological evaluation of the test compounds was carried out in six different tumoral cell lines. The factors that affect the cytotoxic activity

Provided is a rubber composition that has better weather resistance than conventional rubber compositions and can inhibit surface discoloration of a rubber article. The rubber composition contains at least one rubber component selected from natural rubber and diene-based synthetic rubbers and, blended therewith, at least one amine compound represented by formula (I) shown below. In formula (I), R1 and R2 each represent, independently of one another, an alkyl group having a carbon number of 1-10, an aralkyl group, or a phenyl group, and A represents an alkylene group having a carbon number of 6-30 that may include an interposed phenylene group.
