I! CH2COOYT)2q (hereinafter simply referred to as sesquioxide) was successfully synthesized (J, A, C, S, 98,
8287, (76)), and when we tested the pharmacological effects of this sesquioxide, we found that it has an extremely strong antihypertensive effect,
Although it exhibits physiological activities such as antitumor effects, it has become clear that it does not exhibit any toxicity or side effects, and has attracted much attention in the pharmaceutical and academic circles. However, the mechanism of the physiological activity of the sesquioxide has not been clearly elucidated, or it is presumed that it is due to the germanium-oxygen bond formed in the sesquioxide. If it is possible to synthesize an organic germanium compound in which adjacent atoms are substituted, that organic germanium compound will exhibit stronger physiological activity in new aspects compared to conventionally known organic germanium compounds such as the sesquioxides. can be fully expected.
