  A Novel Series of 4-Piperidinopyridine and 4-Piperidinopyrimidine Inhibitors of 2,3-Oxidosqualene Cyclase−Lanosterol Synthase

  摘要：

  A novel series of 4-piperidinopyridines and 4-piperidinopyrimidines showed potent and selective inhibition of rat 2,3-oxidosqualene cyclase-lanosterol synthase (OSC) (e.g. 26 IC50 rat = 398 +/- 25 nM, human = 112 +/- 25 nM) and gave selective oral inhibition of rat cholesterol biosynthesis (26 ED80 = 1.2 +/- 0.3 mg/kg, n = 5; HMGCoA reductase inhibitor simvastatin, ED80 = 1.2 +/- 0.3 mg/kg, n = 5). The piperidinopyrimidine OSC inhibitors have a significantly lower pK(a) than the corresponding pyridine or the previously reported quinuclidine OSC inhibitor series. This indicates that other novel OSC inhibitors may be found in analogues of this series across a broader pK(a) range (6.0-9.0). These series may yield novel hypocholesterolemic agents for the treatment of cardiovascular disease.
