Discovery and development of statins polar methane sulfonamide group, which is quite hydrophilic and confers low lipophilicity. The sulfonamide group forms a unique polar interaction with the enzyme. As a result, rosuvastatin has superior binding affinity to the HMGR enzyme compared to the other statins, which is directly related to its efficiency to lower LDL cholesterol. Lipophilicity of the statins is considered to be quite important since the hepatoselectivity of the statins is related to their lipophilicity. The more lipophilic statins tend to achieve higher levels of exposure in non-hepatic tissues, while the hydrophilic statins tend to be more hepatoselective. The difference in selectivity is
Illegal drugs in Puerto Rico the Puerto Rican police have struggled to work together and some commentators have questioned the effectiveness of government drug policy. In the early 1990s, law enforcement began specifically targeting white collar drug users. By 2008 the tension was rising. The start of what some call the "drug war" was in 2009 in a conflict between Police and drug dealers which police wounded and killed two men. This occurred in Naranjito, Puerto Rico, the place where the drug dealers distributed their drugs to many places in Puerto Rico. In the house they found AK-47, M9 pistols and the drugs. Also they
