Use of synthetic fluorescent ceramide molecules allows the discovery of the first selective drug-like smallmoleculeinhibitors for alkaline ceramidase 3, an intra-membrane enzyme involved in sphingolipid metabolism in health and disease. These inhibitors represent a new paradigm for controlling lipid metabolism with drug-like smallmolecules targeting conformationally dynamic membrane proteins.

A novel and simple approach for the preparation of 3-substituted, 5-substituted, or 3,5-disubstituted hydantoins is reported. It involves the reaction of α-amino methyl ester hydrochlorides with carbamates to yield the corresponding ureido derivatives, which subsequently cyclize under basic conditions to produce substituted hydantoins in good yields. By applying this method, the bioactive anticonvulsant
The present invention provides an improved process for the preparation of carbamates with high selectivity of pharmaceutical interest by an eco-friendly, non-toxic, phosgene-/isocyanate-/CO-free clean route through a reaction of amine, organic halide compound and carbon dioxide in the presence of a solid, reusable catalyst at moderate conditions and does not require additional cocatalyst/promoter as well as solvent
