represents an alternative approach to enhance the beneficial actions of adenosine as compared to direct-acting receptor agonists. Clitocine (3), isolated from the mushroom Clitocybe inversa, has been found to be a weak inhibitor of AK. We have prepared a number of analogues of clitocine in order to improve its potency and demonstrated that 5'-deoxy-5'-amino-clitocine (7) improved AK inhibitory potency by 50-fold
腺苷激酶(AK)是负责腺苷代谢的主要酶。与直接作用受体激动剂相比,对AK的抑制有效地增加了细胞外腺苷浓度,并代表了增强腺苷有益作用的另一种方法。从蘑菇Clitocybe inversa中分离出来的Clitocine(3)是AK的弱抑制剂。我们准备了许多clitocine的类似物,以提高其效力,并证明5'-脱氧-5'-氨基-clitocine(7)将AK抑制效力提高了50倍。
