A leucine ester and amino acid-containing building block
H-Leu-OtBu is a leucine ester and an amino acid-containing building block.1,2 It increases phosphorylation of the mTORC1 substrate p70 ribosomal S6 kinase (p70S6K) and inhibits L-[14C]leucine uptake into HeLa S3 cells endogenously expressing L-type amino acid transporter 1 (LAT1) when used at concentrations of 0.4 and 1 mM, respectively.2 H-Leu-OtBu has been used in the synthesis of peptide-based ligands of the neurokinin-1 (NK1) receptor.1
