摘要
Ｇｅ－１３２是具有广泛生物活性的一元羧酸有机锗倍半氧化物的低聚物，分子中存在类似冠醚的Ｇｅ－Ｏ－Ｇｅ大环结构．因此，有人认为Ｇｅ－１３２的生物活性可能与这种大环结构与体内金属离子形成配合物有关［１］，但尚无直接的实验证据．因此，合成Ｇｅ－１３２稀土配...
The complexes of a series of rare earths with Ge 132 have been prepared. The carboxyl anions of Ge 132 molecule were coordinated to rare earth ion with chelate style. In the complexes molecule, the GeO 3/2 group of Ge 132 were hydrolyzed to become Ge(OH) 3 group, and later does not coordinate with rare earth ions. All of the complexes possess similar properties. In aqueous solution of pH 6 and 50 ℃, these complexes can obviously selectively catalytically hydrolize the phosphatide bond of 5 AMP and 5 dAMP into phosphatic acid and riboside.
