Lapaquistat acetate 生物活性

描述 Squalene synthase (SQS) catalyzes the conversion of two farnesyl pyrophosphates to squalene, an important intermediate in between isoprene and valuable triterpenoids[3]. Squalene synthase was up-regulated in CL1-5 cells and in the tumor regions of the lung cancer specimens. Loss of function or knockdown of SQS significantly inhibited invasion/migration and metastasis in cell and animal models and vice versa. High expression of SQS was significantly associated with poor prognosis among patients with lung cancer. Mechanistically, SQS contributed to a lipid-raft-localized enrichment of tumor necrosis factor receptor 1 in a cholesterol-dependent manner, which resulted in the enhancement of nuclear factor-κB activation leading to matrix metallopeptidase 1 up-regulation[4]. Lapaquistat acetate (TAK-475) is a squalene synthase inhibitor, blocking the conversion of farnesyl diphosphate (FPP) to squalene in the cholesterol biosynthesis pathway[5]. Lapaquistat acetate is effective at lowering low-density lipoprotein cholesterol, but it might cause liver damage. Lapaquistat acetate is used for hypercholesterolemia and mevalonate kinase deficiency (MKD) research[6]. Lapaquistat acetate (diet supplemented; 100 or 200 mg/kg; 32 weeks) decreases plasma cholesterol and triglyceride levels. It delays progression of coronary atherosclerosis and changes coronary atheromatous plaques from unstable, macrophage/lipid accumulation-rich, lesions to stable fibromuscular lesions in vivo[7].
