IMIDAZOPYRIMIDINE, IMIDAZOPYRAZINE AND IMIDAZOPYRIDAZINE DERIVATIVES AS MELANOCORTIN-4 RECEPTOR MODULATORS

摘要

The present invention relates to substituted imidazopyrimidine derivatives, substituted imidazopyrazine derivatives and substituted imidazopyridazine derivatives as melanocortin-4 receptor (MC-4R) modulators, in particular as melanocortin 4 receptor antagonists. The antagonists are useful for the treatment of disorders and diseases such as cachexia induced by e.g. cancer, chronic kidney disease (CKD) or chronic heart failure (CHF), muscle wasting, anorexia induced by e.g. chemotherapy or radiotherapy, anorexia nervosa, amyotrophic lateral sclerosis (ALS), pain, neuropathic pain, anxiety and depression, nausea and emesis.
