Starting from a 3D-model for the antineoplastic activity of diarylsulfonylureas several new features were proposed and tested. Both types of assayed compounds, the N-(2-pyridylsulfonyl)urea and N-(2-pyridylsulfenyl)urea derivatives, inhibited by 50% the growth of the CCRF-CEM cell line at a dosage near to 1 microM.
The N -(2-pyrimidinyl) derivative of the sulfenylurea 6c showed a better profile against HT-29, K-562 and HTB-54 tumor cell lines than the corresponding sulfonylurea 6b.
Structural modifications on aryl systems affected differently to the cytotoxic activity shown by the compounds against each cell line.
