small‐molecule inhibitor of the repairenzyme 8‐oxo‐dGTPase (MTH1) is presented, which is an unconventional cyclometalated ruthenium half‐sandwich complex. The organometallicinhibitor with low‐nanomolar activity displays astonishing specificity, as verified in tests with an extended panel of protein kinases and other ATP binding proteins. The binding of the organometallicinhibitor to MTH1 is investigated
提出了基于探针发现修复酶 8-oxo-dGTPase (MTH1) 的第一个小分子抑制剂,这是一种非常规的环金属化钌半夹心复合物。具有低纳摩尔活性的有机金属抑制剂显示出惊人的特异性,这在一系列蛋白激酶和其他 ATP 结合蛋白的测试中得到证实。通过蛋白质晶体学研究有机金属抑制剂与 MTH1 的结合。

The possibility of deriving a potent, cell-penetrating inhibitor of humanerythrocyte PI 4-kinase, competitive with respect to ATP, has been investigated in a series of purine derivatives and analogues. The purine nucleus is not essential for binding to the ATP site but offers the advantage of synthetic accessibility to its derivatives. The optimum substitution pattern in purine was found to be an
