16084098-3	2005	Herein, we report the structure-activity relationship (SAR) and binding mechanism of three biflavones, amentoflavone (AMF1), 4"""-methylamentoflavone (AMF2) and 7"",4"""-dimethylamentoflavone (AMF3), isolated from Taxodium mucronatum by us as novel natural inhibitors of human CatB with strong inhibitory activities at IC50 values of 1.75, 1.68 and 0.55muM, respectively.	amentoflavone	103-116	G protein pathway suppressor 2	Homo sapiens	118-122
