Several 2-(aminomethyl)-and 2-(2-aminoethyl)-pyrrolidine-3,4-diol derivatives have been assayed for their inhibitory activities towards glycosidases. Good inhibitors of alpha-mannosidases must have the (2R,3R,4S) configuration and possess 2-(benzylamino)methyl substituents. Stereomers with the (2S,3R,4S) configuration are also competitive inhibitors of alpha-mannosidases, but less potent as they share
已经测定了几种2-(氨基甲基)-和2-(2-氨基乙基)-吡咯烷-3,4-二醇衍生物对糖苷酶的抑制活性。好的α-甘露糖苷酶抑制剂必须具有(2R,3R,4S)构型并具有2-(苄基氨基)甲基取代基。具有(2S,3R,4S)构型的立体异构体也是α-甘露糖苷酶的竞争性抑制剂,但效力较低,因为它们共享β-D-甘露糖苷的C(1),C(2),C(3)构型比α-D-甘露糖苷 有趣的是,(2S,3R,4S)-2- [2-[((4-苯基)苯基氨基]乙基]吡咯烷-3,4-二醇(12g)抑制几种酶,例如牛附睾中的α-L-岩藻糖苷酶( K(i)= 6.5microM,竞争性),来自牛肝的α-半乳糖苷酶(K(i)= 5microM,混合)和来自杰克豆的α-半乳糖苷酶(K(i)= 102microM,混合)。二胺,例如(2R,3S,
