- Synthesis of certain diarylsulfonylureas as antitumor agents
-
A new series of N-aryl-N′-heteroaryl or N,N′-diheteroaryl sulfonylurea or sulfonylthiourea was synthesized and screened for their antitumor activity at the National Cancer Institute (NCI). N-(3-Chlorophenyl)-N′-(6-methyl-uracil-2-sulfonyl)urea (28) with GI50, TGI, LC50 (MG-MID) values of 66.1, 83.2, 93.3 μM, respectively is the most active compound in this study. It showed a remarkable activity more than sulofenur against HL-60 (TB) and RPMI-8226 leukemia, HOP-92 Non small lung cancer, KM12 colon cancer, SF-295 CNS cancer, PC-3 prostate cancer, OVCAR-4 Ovarian cancer, CAKI-1 and UO-31 Renal cancer, and MDA-MB-435 Breast cancer with GI50 values of 0.3, 2.7, 6.9, 14.7, 8.2, 9.3, 2.0, 2.1, 3.4, 11.3 μM, respectively.
