Abstract

Glutamine and tyrosine-based amino acid conjugates of Monocarboxylate Transporter types 1 and 2 inhibitors (MCT1/2) were designed, synthesized and evaluated for their potency in blocking the proliferation of a human B lymphoma cell line that expresses the transporters ASCT2, LAT1 and MCT1. Appropriate placement of an Amino acid Transporter recognition element was shown to augment anti-tumour efficacy vs. Raji cells. Amino acid conjugation also improves the pharmacodynamic properties of experimental MCT1/2 inhibitors.
