Abstract:
Aiming at identifying new scaffolds to generate beta-secretase (BACE1) inhibitors we developed peptidomimetics based on a 1,4-benzodiazepine core (3a-d), their seco-analogs (4a-b), and linear analogs (5a-h), by stereoselective approaches. We herein discuss the synthesis, molecular modeling and in vitro studies for the newly developed ligands. Compounds 5c and 5h behaved as BACE1 inhibitors on the isolated enzyme and in cellular studies. Particularly, for its low molecular weight, inhibitor 5h is a prototypic hit to develop a series of BACE1 inhibitors more potent and active on whole-cells.

Indirect-Acting Cholinergic Agonists: Mechanism of Action
Reversible inhibitors like edrophonium bind to a specific part of the enzyme called the anionic catalytic site. They form noncovalent bonds, which means they are not strongly attached to the enzyme. This creates a temporary and less stable enzyme–inhibitor complex,...
