Sulfoximine- and sulfilimine-based diamino-diphenyl sulfone (DAPSON) analogues have been prepared and their COX-1 and COX-2 inhibition potencies as well as LTBand TNF binding properties were studied. Furthermore, their antiproliferative activities on cancer cell growth were investigated. Neither compounds showed significant bioactivities. Copyright © 2012 by Thieme Medical Publishers, Inc.

The syntheses and biological profiles of sulfoximine-based Vioxx® analogs 2 are described. Interesting data have been obtained for 2a, which shows a selective COX-2 inhibition (albeit not as strong as Vioxx® itself) exhibiting reduced hERG activity compare to the parent sulfone Vioxx® (1). © 2011 Elsevier Ltd.

From insects to cancer: N-Cyano sulfoximines were evaluated for COX inhibition and antiproliferative activity against a panel of cancer cell lines. The most active compound exhibited potent COX-2 inhibition, some selectivity for COX-2 over COX-1, only slight cytotoxicity towards healthy cells (HaCaT skin cells), and no mutagenic potential (as determined by an Ames assay). © 2013 WILEY-VCH Verlag GmbH & Co.

Sulfoximine-based acyclic triaryl olefins 8 and 9 have been prepared and initial studies have been performed to determine their biological profiles. In contrast to their sulfonyl-substituted analog 2 sulfoximines 8 and 9 show low COX inhibitory activity. All compounds affect the estrogen receptors. While sulfone 2 interacts exclusively with ER β, sulfoximines 8 and 9 reveal almost equal blocking potencies for both estrogen receptors, ER α and ER β. In the tested series, triaryl olefin 9a shows the highest inhibitory activities with 91% and 80%, respectively (at 10 μM). © 2012 Elsevier Ltd. All rights reserved. Source
