Syntheses and biological activities of sulfoximine-based acyclic triaryl olefins
2012
Abstract 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).
