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

In a search for more selective anticancer drugs, we have designed nitrogen mustard and nitrosourea conjugates leading to a series of N-4-aryl-N′-2-chloroethylureas (CEUs). The iodinated derivative N-4-iodophenyl-N′-2-chloroethylurea (4-ICEU) has demonstrated significant antineoplastic and antiangiogenic potency in preclinical evaluations. In this study, 4-ICEU was radiolabelled with [125I]iodide in order to carry out a comparative study of its in vivo behavior profile. 4-[125I]-ICEU was synthesized by direct electrophilic radioiodination with 80% radiochemical yield and 97% radiopurity. Three different routes of administration (intraperitoneal (ip), intravenous (iv) and intratumoral (it)) were tested in mice bearing subcutaneously implanted CT-26 murine colon carcinoma. The results clearly established that 4-ICEU was more stable to biotransformation than previously studied CEUs congeners. It was readily bioavailable and reached the CT-26 colorectal tumor regardless of the route of administration. Additionally, the colon mucosa was an important target tissue where 4-ICEU accumulated and remained largely untransformed. In conclusion, these results justify further investigations for developing 4-ICEU as a new chemotherapeutic agent for colorectal cancer.
