Meldonium dihydrate
Based on 5 publication(s) in Google Scholar
Meldonium (MET-88) dihydrate functions as a cardioprotective agent by cpmpetetively inhibiting γ-butyrobetaine hydroxylase (BBOX) and carnitine/organic cation transporter type 2 (OCTN2). Mildronate dihydrate exhibits IC50 values of 34-62 μM for human recombinant BBOX and an EC50 of 21 μM for human OCTN2. Meldonium dihydrate is a fatty acid oxidation inhibitor.

Biological Activity
IC50: 34-62 μM (human recombinant BBOX).
EC50: 21 μM (human OCTN2).
Meldonium (20-40 μM; 24 h) dihydrate ameliorates lung injury by targeting PFKP to regulate glycolysis, which promotes Nrf2 translocation from the cytoplasm to the nucleus to alleviate oxidative stress and mitochondrial damage under hypoxic condition[3].
