The invention relates to inhibitors of glucosylceramide synthase (GCS) useful for the treatment metabolic diseases, such as lysosomal storage diseases, either alone or in combination with enzyme replacement therapy, and for the treatment of cancer.
series of quinuclidine derivatives incorporating a tricyclic system was synthesized and evaluated for their ability to inhibit squalene synthase in vitro. A 9H-fluorene moiety was found to be optimal as the tricyclic system for potent inhibitory activity. Improved activity can be achieved with a conformationally constrained three-atom linkage connecting the tricyclic system with the quinuclidine nucleus

A study of the isomerization of methyl (E)-3-quinuclidinylideneacetate derivative to the corresponding Z-isomer is reported. Theoretical calculations, performed using the MM3 molecular mechanics method, are in agreement with the experimental results. A facile and practical procedure for the stereoselective synthesis of methyl (Z)-3-quinuclidinylideneacetate derivative, via the Homer-Wadsworth-Emmons reaction with sodium methoxide in methanol, is also described.
