Nonsteroidal Selective Glucocorticoid Modulators: The Effect of C-10 Substitution on Receptor Selectivity and Functional Potency of 5-Allyl-2,5-dihydro-2,2,4-trimethyl-1H-[1]benzopyrano[3,4-f]quinolines

receptors (PR, MR, AR, ER). Optimal analogues showed slightly less potent but highly efficacious E-selectin repression with reduced levels of GRE activation efficacy in reporter gene assays relative to prednisolone. Preliminary SAR of analogues containing substitution at the C-9 and C-10 positions identified the 9-OH, 10-OMe analogue 50 and the 9-OH, 10-Cl analogue 58 as compounds that demonstrated potent
一系列C-10取代的5-烯丙基-2,5-二氢-2,2,4-三甲基-1H- [1]苯并吡喃并[3,4-f]喹啉的制备和表征描述了糖皮质激素受体的配体。用线性,两个原子的附件(OCH(3),OCF(2)H,NHMe,SMe,CH = CH(2),Ctbd1; CH,CH(2)OH )提供了对人糖皮质激素受体(hGR)的高亲和力(K(i)= 2-8 nM)分子,与其他类固醇受体(PR,MR,AR,ER)的交叉反应性有限。相对于泼尼松龙,最佳的类似物在报告基因试验中显示出稍弱但有效的E-选择素抑制作用,并且GRE激活功效水平降低。在C-9和C-10位置含有取代基的类似物的初步SAR鉴定为9-OH,10-OMe类似物50和9-OH,10-Cl类似物58为化合物,它们在伴刀豆球蛋白A刺激的啮齿动物和人全血单核细胞中均表现出有效的,GR介导的抑制作用。当评估它们在大鼠角叉菜胶诱发的爪水肿中的体内作用时,
