Application

TAK-475 has been used:
  • as a farnesyl-diphosphate farnesyltransferase 1 (FDFT1) inhibitor to study its effects on cell signaling in pancreatic ductal adenocarcinoma cells
  • as a squalene synthase (SQS) inhibitor to stabilize HMG-CoA reductase (HMGCR)-dCat-ELuc proteins
  • as an SQS inhibitor to study its effects on the migration of prostate cancer cells

Biochem/physiol Actions

TAK-475 (Lapaquistat acetate) is a potent and selective squalene synthase inhibitor. TAK-475 effectively lowers low-density lipoprotein cholesterol in human. Clinical development of TAK-475 was discontinued due to hepatotoxicity seen in two patients receiving a high dose.

The pharmacokinetics of TAK-475 (lapaquistat acetate), a squalene synthase inhibitor, was investigated in rats and dogs. After oral administration of (14)C-labeled TAK-475 ([(14)C]TAK-475) to rats and dogs at a dose of 10 mg/kg, the bioavailability (BA) was relatively low at 3.5

Lapaquistat acetate is a squalene synthase inhibitor investigated for the treatment of hypercholesterolemia. This report summarizes the phase 2 and 3 results from the lapaquistat clinical program, which was halted at an advanced stage as a result of potential hepatic

TAK-475 (lapaquistat acetate) and its active metabolite-I (TAK-475 M-I) inhibit squalene synthase, which catalyzes the conversion of farnesyl diphosphate (FPP) to squalene. FPP is a substrate for synthesis of other mevalonate-derived isoprenoids (MDIs) such as farnesol (FOH), geranlygeranyl diphosphate (GGPP)

HMG-CoA reductase (HMGCR) is the rate-limiting enzyme in the cholesterol biosynthetic pathway, and is the target of cholesterol-lowering drugs, statins. Previous studies have demonstrated that the enzyme activity is regulated by sterol-induced degradation in addition to transcriptional regulation through sterol-regulatory-element-binding

Pancreatic ductal adenocarcinoma (PDA) is a deadly cancer characterized by complex metabolic adaptations that promote survival in a severely hypoxic and nutrient-limited tumor microenvironment (TME). Modeling microenvironmental influences in cell culture has been challenging, and technical limitations have hampered the
