An Mn2+ complex with 2,2′:6′,2″-terpyridine (terpy) was found to promote the hydrolysis of NpN (NpN = diribonucleoside monophosphate diester) efficiently at pH 7.0 and 50 °C under ambient conditions. The structure of the Mn2+ complex involving a phosphodiester molecule, [(terpy)(dpp)MnII(μ-dpp)2MnII(dpp)(terpy)], dpp = diphenyl phosphate anion, was established by X-ray crystallography, and the coordination mode of Mn2+ to a phosphodiester molecule was considered.
在常温常压下,于pH 7.0和50°C条件下,发现一种含2,2′:6′,2″-三联
吡啶(terpy)的Mn2+配合物能高效促进NpN(NpN = 二核苷酸单
磷酸二酯)的
水解。通过X射线结晶学确定了涉及
磷酸二酯分子的Mn2+配合物[(terpy)(dpp)MnII(μ-dpp)2MnII(dpp)(terpy)]的结构,其中dpp =
二苯基磷酸盐阴离子,并考虑了Mn2+与
磷酸二酯分子的配位方式。
