Pricing Availability Delivery Time Qty
Cat.No. 3776 - Atorvastatin hemicalcium salt | C33H34FN2O5.½Ca | CAS No. 134523-03-8
Description: Potent HMG-CoA reductase inhibitor
Alternative Names: Lipitor
Chemical Name: (R,R)-2-(4-Fluorophenyl)-β,δ-dihydroxy-5-(1-methylethyl)-3-phenyl-4-[(phenylamino)carbonyl]-1H-pyrrole-1-heptanoic acid hemicalcium salt
Purity: ≥99% (HPLC)

Biological Activity

Potent HMG-CoA reductase inhibitor (IC50 = 8 nM). Reduces circulating LDL-C by inhibiting cholesterol biosynthesis and inducing expression of LDL receptors. Inhibits smooth muscle cell proliferation in vitro and exhibits antinociceptive effects in the inflammatory hypernociception model.
