Chiral centers in atorvastatin
WebThe enantiomeric separation between Atorvastatin (the Active Pharmaceutical Ingredient or API) depicted in Figure 1 and related compound E (the enantiomer of Atorvastatin) is important for the analysis of chiral drug purity. In this technote we report the enan-tiomeric separation using the new Lux Amylose-1 chiral stationary WebAn amino acid has the general formula H₂N-CH (R)-COOH, where R stands for the different acids. Notice that the central C atom is chiral — it has four different groups attached — so the molecule can exist as a pair of enantiomers (nonsuperimposable mirror images). One of these is the D isomer, and the other is L (i.e. a pair of R/S isomers).

WebThe rule of thumb is: chiral carbon centers are carbon atoms that are attached to four different substituents, that are placed at the corners of a tetrahedron. Chiral carbon atoms are also referred to as ‘stereogenic carbons’ or ‘asymmetrical carbon atoms’. Compound …
WebStatins have two chiral centers in their molecules, thus they form four enantiomers (3R5R-, 3R5S-, 3S5R- and 3S5S-). Regarding the most frequently prescribed statins, following enantiopure formulations are used in the clinics: 3R5R-atorvastatin, 3R5S-rosuvastatin and 3R5S-fluvastatin. Individual enantiomers of one drug can qualitatively and ...
