Mildronate (Meldonium) functions as a cardioprotective drug by competetively inhibiting BBOX1 and OCTN2. Mildronate (Meldonium) exhibits IC50 values of 34-62 μM for human recombinant BBOX and an EC50 of 21 μM for human OCTN2. Mildronate (Meldonium) treatment-induced redirection of long-chain FA metabolism from mitochondria to peroxisomes.
