Provided herein are peptides having dual-site BACE1 inhibitory activity, useful for the treatment of, for example Alzheimer's disease and diabetes. One such peptide is a dual-site BACE1 inhibitor, or a pharmaceutically acceptable salt thereof, binding to both an enzymatic active site and an catalytic domain of the BACE enzyme, and an exosite inhibitory part is connected to an active-site inhibitory part of the dual site BACE1 inhibitor by a linker.

The present invention relates to dual-site BACE1 inhibitors, their manufacture, pharmaceutical compositions containing them and their use as therapeutically active substances. The active compounds of the present invention are useful in the therapeutic and/or prophylactic treatment of e.g. Alzheimer's disease.

The present invention relates to a compositions and methods for treating and/or preventing neurologic disorders such as Alzheimer's disease and disorders associated with an increase of the Th2 immune response such as allergic inflammation.
