A number of N-acyl substituted hydroxyethylaminomethyl-4H-chromen-4-ones 6a–u were prepared and evaluated for their IL-5 inhibitory activity. Among them, the compound 6r (95.0% inhibition at 30 µM, IC50 = 10.0 µM, C log P = 4.1549) showed most potent inhibitory activity. The structure activity relationship revealed that the bulkier or hydrophobic substituents at urea, carbamate or amide group resulted
制备了许多N-酰基取代的羟乙基氨基甲基-4 H-铬基-4-酮6a – u并评估了其对IL-5的抑制活性。其中,化合物6r(在30 µM时抑制率为95.0%,IC 50 = 10.0 µM,C log P = 4.1549)显示出最有效的抑制活性。结构活性关系表明,尿素,氨基甲酸酯或酰胺基团上较大或疏水的取代基对IL-5具有良好的抑制活性。此外,苯环上的给电子基团(6g和6s)比吸电子基团(6f)更具活性)。最后,用大的脂族取代基取代环A第5位的环己基甲氧基导致活性丧失。
