Antimitotic Antitumor Agents: Synthesis, Structure−Activity Relationships, and Biological Characterization of <i>N</i>-Aryl-<i>N</i>‘-(2-chloroethyl)ureas as New Selective Alkylating Agents
series of N-aryl-N'-(2-chloroethyl)ureas (CEUs) and derivatives were synthesized and evaluated for antiproliferative activity against a wide panel of tumor cell lines. Systematic structure--activity relationship (SAR) studies indicated that: (i) a branched alkyl chain or a halogen at the 4-position of the phenyl ring or a fluorenyl/indanyl group, (ii) an exocyclic urea function, and (iii) a N'-2-chloroethyl
