Abstract

OBJECTIVE: Initial studies on the use of non-physiological amino acids (NPAAs) to block the accretion of Phe in the brain

METHODS: Control and

RESULTS: MAIB was partially converted to AIB

CONCLUSIONS: Our data support further pharmacokinetic characterization of MAIB and AIB in preparation for further preclinical safety, toxicity and tolerability studies of both AIB and MAIB.

Keywords: Aminoisobutyric Acid; LAT-1 Transporter; Large Neutral Amino Acids; Methylaminoisobutyric Acid; Pharmacokinetics; Phenylalanine; Phenylketonuria
