Optimised quinuclidine squalene synthase (SQS) inhibitors are reported; 3-[2-(2-allyl-4-(2-ethoxy carbonylethyl)phenyl)ethynyl]quinuclidin-3-ol 1c, is a potent inhibitor of rat (KI = 6 nM) and human (KI = 43 nM) microsomal SQS; the oral ED(50) of 1c, for the inhibition of rat cholesterol biosynthesis was 1.3+/-0.45 mg/kg and for the R-enantiomer 1m, 0.8+/-0.2 mg/kg, with the corresponding R-carboxylic acid 6a, being 0.9+/-0.25 mg/kg.
