Discovery and development of statins walls of people that died from occlusive vascular diseases, like myocardial infarction. The cholesterol was found to be responsible for the thickening of the arterial walls and thus decreasing the radius in the arteries which leads in most cases to hypertension and increased risk of occlusive vascular diseases. In the 1950s the Framingham heart study led by Dawber revealed the correlation between high blood cholesterol levels and coronary heart diseases. Following up from that study the researchers explored a novel way to lower blood cholesterol levels without modifying the diet and lifestyle of subjects suffering with elevated blood cholesterol levels.
Discovery and development of statins that the statins exploit and is used to accommodate their hydrophobic moieties. The specificity and the tight binding of statins is due to orientation and bonding interactions that form between the statin and the HMGR enzyme. Polar interactions are formed between the HMG-moiety and residues that are located in the cis loop of the enzyme. These polar interactions are between Ser, Asp, Lys and Lys (Figure 4). The terminal carboxylate of the HMG moiety forms a salt bridge with the cationic Lys of the enzyme. In addition to the polar interaction, Lys participates in a hydrogen bonding network with Glu,
