4.3.1.18 | pharmacology | decrease in D-serine content may provide a therapeutic strategy for the treatment of the neurological disorders in which overstimulation of N-methyl-D-aspartate receptors plays a pathological role. D-Serine dehydratase (Dsd1p), which acts dominantly on D-serine, may be a useful D-serine reducing agent. A linear 5-kDa polyethylene glycol (PEG) is conjugated to Dsd1p and the effects of PEG-conjugation on its biochemical and pharmacokinetic properties are examined. PEG-Dsd1p retains activity, specificity, and stability of the enzyme. The PEG modification extended the serum half-life of Dsd1p in mice 6fold, from 3.8 h to 22.4 h. PEG-Dsd1p is much less immunogenic compared to the unmodified enzyme. Intraperitoneal administration of PEG-Dsd1p is effective in decreasing the D-serine content in the mouse hippocampus | Saccharomyces cerevisiae |
