USE OF SUBSTITUTED DIPHENYL INDANONE, INDANE AND INDOLE COMPOUNDS FOR THE TREATMENT OR PREVENTION OF SICKLE CELL DISEASE, INFLAMMATORY DISEASES CHARACTERIZED BY ABNORMAL CELL PROLIFERATION, DIARRHEA AND SCOURS

摘要

The present invention provides substituted 3,3-diphenyl indanone, indane and indole compounds, as well as analogues thereof which are specific, potent and safe inhibitors of the Ca2+-activated potassium channel (Gardos channel) of erythrocytes, of mammalian cell proliferation and/or of secretagogue-stimulated transepithelial electrogenic chloride secretion in intestinal cells. The compounds can be used to reduce sickle erytrocyte dehydration and/or delay the occurrence of erythrocyte sickling or deformation in situ as a therapeutic approach towards the treatment or prevention of sickle cell disease. The compounds can also be used to inhibit mamalian cell proliferation in situ as a therapeutic approach towards the treatment or prevention of diseases characterized by abnormal cell proliferation. Furthermore, the compounds can also be used to inhibit chloride secretion in intestinal cells as a therapeutic approach towards the treatment of diarrhea and scours.
