Inhibitor Comments
The inhibition of HMG-CoA reductase by rosuvastatin is competitive with respect to the substrate HMG-CoA , and noncompetitive with respect to co-substrate NADPH [33]. IC50 values of rosuvastatin have been shown to vary according to whether a cell-free system of cell-culture based assay is used [56].

Some of the inhibitors above have been selected as representative structures from sets of stucturally similar compounds with bioactivity data at this target on ChEMBLdb.
