2-(Dialkylamino)-4H-1-benzopyran-4-one derivatives modify chloride conductance in CFTR expressing cells
摘要:
Some 2-(diethylamino)-7-hydroxy-4H-1-benzopyran-4-one derivatives, potentially useful as activators of the cystic fibrosis transmembrane conductance regulator (CFTR), were prepared. The synthesized compounds were tested, together with others 2-(dialkylamino)-7-hydroxybenzopyran-4-one derivatives, by measuring their capacity to modify the kinetics of iodide influx in Fisher rat thyroid cells expressing wild type CFTR and the halide-sensitive yellow fluorescent protein. Among the tested compounds the dinitrile derivatives 8 and 9 are endowed with an activity comparable to the reference compound apigenin.
of compounds with dual activity toward cysteinyl leukotriene receptor 1 (CysLT1R) and G-protein-coupled bile acid receptor 1 (GPBAR1). They are derivatives of REV5901─the first reported dual compound─with therapeutic potential in the treatment of colitis and other inflammatory processes. We report the binding mode of the most active compounds in the two GPCRs, revealing unprecedented structural basis

A new and one-pot synthesis of benzofuran fused N-heterocycles has been accomplished via AlCl3-mediated C–C followed by C–Obondformationbetween 2,3-dichloropyrazine or its derivatives and phenols. The methodology provided novel compounds as potential inhibitors of PDE4B. The single crystal X-ray data of a synthesized benzofuran derivative are presented. Scope of the methodology, in vitro pharmacological
