The synthesis of 46 derivatives of (2R,3R,4S)-2-(aminomethyl)pyrrolidine-3,4-diol is reported (Scheme 1 and Fig. 3), and their inhibitory activities toward α-mannosidases from jack bean (B) and almonds (A) are evaluated (Table). The most-potent inhibitors are (2R,3R,4S)-2-[([1,1′-biphenyl]-4-ylmethyl)amino]methyl}pyrrolidine-3,4-diol (3fs; IC50(B)=5 μM, Ki=2.5 μM) and (2R,3R,4S)-2-[(1R)-2,3-dihy
(方案1和图3)报道了(2 R,3 R,4 S)-2-(氨基甲基)吡咯烷-3,4-二醇的46种衍生物的合成及其对α-甘露糖苷酶的抑制活性。评价了豆(B)和杏仁(A)(表)。最有效的抑制剂是(2 R,3 R,4 S)-2-[[([(1,1'-联苯] -4-基甲基)氨基]甲基}吡咯烷-3,4-二醇(3fs ; IC 50(B)= 5μM,K i = 2.5μM)和(2 R,3 R,4 S)-2-[(1 R)-2,3-二氢-1 H-茚满-1-基氨基]甲基}吡咯烷-3,4-二醇(3fu;IC 50(B)= 17μM,K i = 2.3μM)。制备了(2 S,3 R,4 S)-2-(氨基甲基)吡咯烷-3,4-二醇(6,RH)和三种2-(N-烷基氨基)甲基衍生物6fh,6fs和6f(方案2),并发现它也抑制了来自杰克豆和杏仁的α-甘露糖苷酶(表)。这些系列中最好的抑制剂是(2 S,3 R,4 S)
