| 摘要 |
The 8-deutero, and 8-tritio-substituted derivatives of D-4S-6-fluoro-spiro-[chroman-4,4'-imidazolidine]-2',5'-dione (sorbinil) have been prepared. These compounds all have the 4S-configuration and are of value in the field of medicinal chemistry as aldose reductase inhibitors for the control of chronic diabetic complications. The labeled 8-deutero and 8-tritio derivatives are useful in metabolism pharmacokinetic studies and in binding studies with the drug in animals and man. The 8-halo derivatives are useful as intermediates for the labeled forms of the drug, in addition to being potent aldose reductase inhibitors per se. Methods for the preparation of these compounds are provided in some detail. |
