small‐molecule inhibitor of the repair enzyme 8‐oxo‐dGTPase (MTH1) is presented, which is an unconventional cyclometalated ruthenium half‐sandwich complex. The organometallic inhibitor 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 organometallic inhibitor 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。
