描述 | The enzyme 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA ) reductase is the rate-limiting enzyme involved in the multistep synthesis of cholesterol. Pitavastatin is a fully synthetic competitive inhibitor of HMG-CoA reductase[4]. Pitavastatin Calcium (NK-104 hemicalcium) inhibits cholesterol synthesis from acetic acid with an IC50 of 5.8 nM in HepG2 cells. Pitavastatin Calcium inhibits the growth of a panel of ovarian cancer cells, including those considered most likely to represent high-grade serous ovarian cancer (HGSOC), grown as a monolayers (IC50 = 0.4-5 μM) or as spheroids (IC50=0.6-4 μM). Pitavastatin Calcium (1 μM; 48 hours ) induces apoptosis, evidenced by the increased activity of executioner caspases-3,7 as well as caspase-8 and caspase-9 in Ovcar-8 cells and Ovcar-3 cells. Pitavastatin (1 μM, 48 hours) caused PARP cleavage in Ovcar-8 cells. Pitavastatin Calcium (59 mg/kg; p.o.; twice daily for 28 days) caused significant tumour regression [5]. EL mRNA expression was inhibited after treatment with pitavastatin for 6 h, and maximal inhibition occurred and reached plateau after treatment for 24 h. The plasma levels of total cholesterol in mice treated with pitavastatin or vehicle were 2.04+0.15 and 2.18+0.23 mmol/L, respectively(n.s.). The plasma HDL-C levels in mice with or without pitavastatin were 1.87+0.11 and 2.02+0.22 mmol/L, respectively (n.s.). EL expression in vivo through the Rho signalling pathway, and the effect was irrespective of the plasma cholesterol levels[6]. |
作用机制 | Pitavastatin increased the mRNA levels of CYP7A1 in HepG2 cells, suggesting that increased conversion of cholesterol to bile acids may be the mechanism for its potent low-density lipoprotein cholesterol-lowering effects[3]. |
