Product Name:Pitavastatin calcium
CAS Number:147526-32-7
Molecular formula:C25H26CaFNO4
Molecular Weight:463.56

Pitavastatin Calcium is a competitive inhibitor of the enzyme HMGCR. Alternate studies show that pitavastatin can suppress oxygen production in endothelial cells by inhibiting Nox. In addition, pitavastatin reduces the expression of eNOS mRNA while increasing the NO dependent response stimulated by acetylcholine and the calcium ionophore, A23187.

Yield:100 % ee

Reaction Conditions:

with Candida rugosa IFO₀₅₉₁ in dimethyl sulfoxide at 30; pH=7; for 20 h;Product distribution / selectivity;Aerobic conditions;potassium phosphate buffer (pH 7.0);

Steps:

16 Example 16; Production of DCOOH from 5-MOLE

Each kind of strains shown in Table 12 was incubated in the same way as that of Example 1, except that 5-MOLE was used instead of DOXE. A spot (developing solvent; hexane:ethyl acetate=1:1, Rf=0) corresponding to the compound (IV) (which is a compound, in the formula, R=hydrogen: hereinafter, abbreviated as DCOOH) on the TLC was scraped off and was then eluted with 0.25 mL of isopropanol. After centrifugation, a supernatant was subjected to a high-performance liquid chromatography (HPLC) under the same conditions as those of Example 15, to analyze the optical purity. The results are listed in Table 12
