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@?M, IC<SUB>50</SUB>=10.0@?M, ClogP=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 in good inhibitory activity against IL-5. Moreover, electron donating group at phenyl ring (6g and 6s) is much more active than electron withdrawing group (6f). Finally, replacement of cyclohexylmethoxy group at 5<SUP>th</SUP> position of ring A with bulky aliphatic substituents resulted in the loss of activity.
