oxygen and hydrogen peroxide at pH = 7.4 of 1.2 x 10(+7) M(-1) s(-1).(1) The use of the computer-aided design paradigm reported previously for this class of Mn(II) complexes(2,3) led to the prediction that the 2S,21S-dimethyl derivative of M40403 should possess superior catalytic SOD activity. The synthesis of this new macrocyclic Mn(II) complex, [manganese(II)dichloro[2S, 21S-dimethyl-(4R,9R,14R,19R)-3
由双环己基-吡啶配合物M40403([锰(II)二氯[(4R,9R,14R,19R)-3,10,13,20,26-五氮杂四环[20.3.1.0 (4,9)0(14,19)] hexacosa-1(26),-22(23),24-三烯]]),在此描述。先前已证明复合物M40403是一种超氧化物歧化酶(SOD)催化剂,在pH = 7.4时超氧化物催化分解为氧气和过氧化氢的速率为1.2 x 10(+7)M(-1)s(-1) (1)使用先前报道的针对此类Mn(II)配合物的计算机辅助设计范式(2,3)导致了预测,即M40403的2S,21S-二甲基衍生物应具有优异的催化SOD活性。这种新的大环Mn(II)配合物,[二氯化锰(II)[2S,21S-二甲基-(4R,9R,14R,19R)-3,10,13,20,26-五甲基四环[20.3.1.0] 。(4,9)0(14,19)] hexacosa-1(2
