Phenytoin-Lipid-Konjugate als potentielle Prodrugs des Phenytoins
Phenytoin-1 -triglycerides and phenytoin-2-triglycerides were synthesized as potential prodrugs of phenytoin by covalent binding of 3-hydroxymethylphenytoin by succinic acid to the positions 1 and 2 of diglycerides, respectively. The corresponding 1-and 2-monoglycerides were prepared. In addition, replacement of glycerol by 3-hydroxy-2-hydroxymethylpropionic acid furnished lipids that allowed direct coupling of 3-hydroxymethylphenytoin. The lipid conjugates proved to be substrates for pancreatic lipase in vitro.
Als potentielle Prodrugs des Phenytoins wurden
Phenytoin-1 -triglyceride und Phenytoin-2-triglyceride durch kovalente Bindung von 3-Hydroxymethylphenytoin mittels Bernsteinsaure an die Positionen 1 bzw. 2 von Diglyceriden synthetisiert. Die entspr. 1bzw. 2-Monoglyceride wurden hergestellt. Der Austausch von Glycerin gegen 3-Hydroxy-2-hydroxymethylpropionsaure fiihrte zu Lipiden, die eine direkte Esterbindung mit 3-Hydroxymethylphenytoin erlaubten. Pankreaslipase hydrolysierte in vitro die Lipid-Konjugate in Analogie zu naturlichen Triglyceriden.
