  • Patent number: 9937165
    Abstract: The invention relates to methods of enhancing normal melanocortin-4 receptor (MC4R) activity, and to enhancing activity of an MC4R having a mutation which affects protein folding and/or processing of the MC4R. The invention provides a method of treating an individual having a condition in which increased activity of an MC4R at the cell surface would be beneficial, for example in obesity, by administering an effective amount of a pharmacological chaperone for the MC4R. The invention provides MC4R pharmacological chaperones which enhance the activity of MC4R. The invention further provides a method of screening to identify pharmacological chaperones which enhance folding of an MC4R in the endoplasmic reticulum (ER), in order to enhance the activity of the MC4R at the cell surface.

  • Publication number: 20100189708
    Abstract: The present invention provides novel hydroxy piperidine (HP) derivatives having (i) a positive charge at the position corresponding to the anomeric position of a pyranose ring; (ii) a short, flexible linker emanating from the corresponding position of the ring oxygen in a pyranose; and (iii) a lipophilic moiety connected to the linker and pharmaceutically acceptable salts thereof. The linker can be absent if the lipophilic moiety corresponds to a hydrocarbon chain with a linear length of 6 or more carbons. The present invention further provides a method for treating individuals having Gaucher disease by administering the novel HP derivative as “active-site specific chaperones” for the mutant glucocerebrosidase associated with the disease.
