Description

Application

• Targeting the cerebrovascular large neutral amino acid transporter (LAT1) isoform using a novel disulfide-based brain drug delivery system.: This paper discusses a novel brain drug delivery system that targets the LAT1 transporter, using 2-Methyl-1-propanethiol in the design of disulfide-based prodrugs for enhanced delivery across the blood-brain barrier (Killian et al., 2007).
