Synthesis, Biological Evaluation, and Structure–Activity Relationships of Novel Substituted N-Phenyl Ureidobenzenesulfonate Derivatives Blocking Cell Cycle Progression in S-Phase and Inducing DNA Double-Strand Breaks
摘要:
Twenty-eight new substituted N-phenyl ureido-benzenesulfonate (PUB-SO) and 18 N-phenylureidobenzene-sulfonamide (PUB-SA) derivatives were prepared. Several PUB-SOs exhibited antiproliferative activity at the micromolar level against the HT-29, M21, and MCF-7 cell lines and blocked cell cycle progression in S-phase similarly to cisplatin. In addition, PUB-SOs induced histone H2AX (gamma H2AX) phosphorylation, indicating that these molecules induce DNA double-strand breaks. In contrast, PUB-SAs were less active than PUB-SOs and did not block cell cycle progression in S-phase. Finally, PUB-SOs 4 and 46 exhibited potent antitumor activity in HT-1080 fibrosarcoma cells grafted onto chick chorioallantoic membranes, which was similar to cisplatin and combretastatin A-4 and without significant toxicity toward chick embryos. These new compounds are members of a promising new class of anticancer agents.

Aryl and heteroaryl para-nitrophenylsulfonates (nosylates) have been successfully engaged for the first time in Suzuki–Miyauracross-couplingreactions with various aryl or vinylboronic acids (48–98%, 12 examples). The best catalyst/ligand combination have been determined to be 2 mol % of palladium acetate (Pd(OAc)2) and 4 mol % of 2-dicyclohexylphosphino-2′,4′,6′-triisopropylbiphenyl (XPhos) using

previous report showed that our current benchmark agent, 4-methoxyphenyl p-toluenesulfonate, is a selective antimalarial/anticancer agent. A series of related sulfones and sulfonic acidesters is now examined. 4-Allyloxyphenyl p-toluenesulfonate is a superior antimalarial/anticancer agent. 4-Methoxyphenyl 4-nitrobenzenesulfonate is a superior antimalarial agent, but shows poorer inhibition of human skin
