1-Aryl-3-(2-chloroethyl) ureas and 1-aryl-3-nitroso-3-(2-chloroethyl) ureas, derived from 4-phenylbutyric acid and alkylanilines, were synthesized and their cytotoxicity was evaluated on human adenocarcinoma cells in vitro. Methyl 4-[p-[3-(2-chloroethyl)ureido]-phenyl]butyrate, 4-methyl [3-(2-chloroethyl)ureido]benzene, and 4-butyl[3-(2-chloroethyl)ureido]benzene were found to be at least as cytotoxic as

Several alkyl[3-(2-chloroethyl)ureido] (CEU) benzene derivatives were prepared as potential anticancer agents. These new compounds were readily prepared in good yields by addition of anilines to 2-chloroethylisocyanate. Their cytotoxic activity was evaluated on human breast cancer (MDA-MB-231), human colon adenocarcinoma (LoVo) and mouse lymphocytic leukemia (P388D(1),) tumor cell lines. Several new CEUs were significantly more cytotoxic than the nitrogen mustard chlorambucil. The biological activity of these aromatic urea derivatives seems to be related to the nature and position of the alkyl substituents on the aromatic ring. Substitution by branched alkyl groups on position 4 of the aromatic ring led to cytotoxic molecules which are up to 5 times more potent than the standard chlorambucil.

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
