Several aniline mustard analogues were obtained by introducing N,N-bis
(2-chloroethyl)amino moiety to phenyl ring of A10 analogues in order t
o increase reactivity of A10 analogs and selectivity into DNA. The in
vitro antitumor activity oi synthesized compounds was evaluated using
five different solid tumor cell lines by SRB method. Aniline mustard a
nalogues exhibited more potent antitumor activity than A10 analogs. Es
pecially, m-aniline mustard of benzoyl analogue displayed remarkable a
ntitumor activity.
