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
The relationship between solvatochromic properties and in silico ADME parameters of new chloroethylnitrosourea derivatives with potential anticancer activity and their β-Cyclodextrin complexes
specific solvent–solute interactions. In detail, the solvatochromic effect of the solventpolarity on the absorption and emission maxima was significant for all CENUs, whereas the solvatochromic effect of the solvent’s ability to donate or accept hydrogen bonds on the absorption and emission maxima was critically dependent on the electron density of the N’-aryl group. From the solvatochromic comparison

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.
