COMPOUNDS AND COMPOSITIONS FOR THE TREATMENT OF PARASITIC DISEASES

The present invention provides compounds of Formula A: or a pharmaceutically acceptable salt, tautomer, or stereoisomer, thereof, wherein the variables are as defined herein. The present invention further provides pharmaceutical compositions comprising such compounds and methods of using such compounds for treating, preventing, inhibiting, ameliorating, or eradicating the pathology and/or symptomology of a disease caused by a parasite, such as leishmaniasis, human African trypanosomiasis and Chagas disease.

SUBSTITUTED AZOANTHRACENE DERIVATIVES, PHARMACEUTICAL COMPOSITIONS, AND METHODS OF USE THEREOF

The present invention is directed to substituted azoanthracene derivatives or pharmaceutically acceptable salts thereof that modulate the human GLP-1 receptor and that may be useful in the treatment of diseases, disorders, or conditions in which modulation of the human GLP-1 receptor is beneficial, such as diabetes mellitus type 2. The invention is also directed to pharmaceutical compositions comprising these compounds and to the use of these compounds and compositions in the treatment of such diseases, disorders, or conditions in which modulation of the human GLP-1 receptor is beneficial.
