Simvastatin acid (Tenivastatin) calcium hydrate is a potent HMG-CoA reductase (HMGCR) inhibitor. Simvastatin acid calcium hydrate reduces Indoxyl sulfate-mediated reactive oxygen species (ROS) production in human cardiomyocytes. Simvastatin acid calcium hydrate can also modulates OATP3A1 expression in cardiomyocytes and HEK293 cells transfected with the OATP3A1 gene.

SRK2128 (SRK 2128) is a highly potent HMG-CoA reductase degrader with EC50 of 84 nM, potently induce degradation of HMG-CoA reductase.
