budmunchamine family of alkaloids, were prepared by total synthesis. They were the [17]-N(4) macrocycle 1, the [16]-N(4) macrocycle 20, the [18]-N(4) macrocycle 13, the [20]-N(5) macrocycle 8, and the [13]-N(3) macrocycle 17. Each one of them hydrolyzed ATP in vitro with release of P(i); the largest ring macrocycle 8 was the most efficient catalyst, while the smallest ring macrocycle 17 was the least
在实体瘤中,当O(2)的分压降至10 mmHg以下时,由于Warburg效应,ATP水平迅速降低。已知某些大环多胺可催化ATP的化学水解并释放出无机磷酸盐。由于与正常细胞相比,肿瘤细胞的ATP水平降低,因此我们试图用大环多胺消耗细胞的ATP,以抑制肿瘤细胞的增殖。通过全合成制备了五种与生物碱的花香胺家族有关的大环多胺。它们是[17] -N(4)宏周期1,[16] -N(4)宏周期20,[18] -N(4)宏周期13,[20] -N(5)宏周期8,和[13] -N(3)大环化合物17。它们每个都在体外水解ATP,并释放P(i)。最大的环状大环8是最有效的催化剂,而最小的环形大环17效率最低(在这些运行中释放的P(i)约为40-100 microM)。线性多胺精胺对ATP没有水解作用。当通过MTT测定针对两种人类前列腺细胞系DuPro和PC-3进行评估时,发现大环具有细胞毒性,其ID(50)值介于0
