Abstract

Acetylhomotaurine was labeled with (11)C via N-acetylation with [(11)C]acetyl chloride. The synthesis yielded 48.2+/-3.8%, decay corrected to end of bombardment. The specific activity of the (radio)chemically pure product was 20.8+/-2.0 GBq/micromol at EOS. In vivo studies revealed a very fast clearance of the tracer from the blood and a uniform distribution in the different brain regions. Unfortunately, the poor passage through the blood brain barrier makes the tracer not suitable for PET studies.

Blood Brain Barrier Chips

The blood brain barrier (BBB) is comprised of endothelial cells that regulate the influx and outflux of plasma concentrations. Lab-on-a-chip devices allow scientists to model diseases and mechanisms such as the passage of therapeutic antibodies across the BBB. Discover the latest research on BBB chips here.
