Abstract

Knock-in transgenic mouse models and human post-mortem studies have demonstrated Caspase-6 (Casp6) activity to be involved in both age-dependent cognitive impairment and Alzheimer disease, suggesting Casp6 as a potential therapeutic target. Although Casp6 inhibitors have been identified, many of them are non-selective. Here, we show that by using a novel human genetic approach, we identified a non-conserved allosteric pocket that bears favorable tertiary architecture for accommodating small molecules. An in silico screen of 77,000 diverse molecules against this pocket identified fifty-four potential Casp6 inhibitors. This thesis will focus on the fifteen hits identified from the Sigma-Aldrich commercial library. In vitro screening of these ...
