Atorvastatin synthesis during discovery chemistry. The key step of establishing stereocenters, using of a chiral ester auxiliary approach. The first synthesis of atorvastatin at Parke-Davis that occurred during drug discovery was racemic followed by chiral chromatographic separation of the enantiomers.
The exact mechanism responsible for the possible increased risk of diabetes mellitus associated with statin use is unclear. [105] However, recent findings have indicated the inhibition of HMGCoAR as a key mechanism. [109] Statins are thought to decrease cells' uptake of glucose from the bloodstream in response to the hormone insulin. [105]
In some literature articles, the terms "mechanism of action" and "mode of action" are used interchangeably, typically referring to the way in which the drug interacts and produces a medical effect. However, in actuality, a mode of action describes functional or anatomical changes, at the cellular level, resulting from the exposure of a living ...
Compounds used as medicines are most often organic compounds, which are often divided into the broad classes of small organic molecules (e.g., atorvastatin, fluticasone, clopidogrel) and "biologics" (infliximab, erythropoietin, insulin glargine), the latter of which are most often medicinal preparations of proteins (natural and recombinant ...
Data from the Cholesterol Treatment Trialists’ (CTT) publication [10] was used to determine the effects of fluvastatin, atorvastatin and rosuvastatin on LDL cholesterol lowering and reduction of myocardial infarction. In two RCTs an average dose of 72 mg/day fluvastatin reduced LDL cholesterol by 31.9%, and reduced myocardial infarction ...
The common myth often refers to the draining action of flush toilets and bathtubs. In fact, rotation is determined by whatever minor rotation is initially present at the time the water starts to drain, as the magnitude of the coriolis acceleration is negligibly small compared to the inertial acceleration of flow within a typical basin.

Cimetidine was the prototypical histamine H 2 receptor antagonist from which later drugs were developed. Cimetidine was the culmination of a project at Smith, Kline & French (SK&F; now GlaxoSmithKline) by James W. Black, C. Robin Ganellin, and others to develop a histamine receptor antagonist that would suppress stomach acid secretion.
Employment Division, Department of Human Resources of Oregon v. Smith, 494 U.S. 872 (1990), is a United States Supreme Court case that held that the state could deny unemployment benefits to a person fired for violating a state prohibition on the use of peyote even though the use of the drug was part of a religious ritual. Although states have ...
