Project Summary Abstract
Caspase-2 has been implicated in neurological indications such as stroke, Alzheimer's, Parkinson's, and
Huntington's diseases, neuroblastoma, neuro-ophthalomology, and frontotemporal dementia. The broad, long-
term objective of our work is the development of specific caspase-2 inhibitors as neuro-therapeutic agents. This
long-term objective hinges on first developing caspase-2 probes that will allow us to show that specific
pharmacological reduction of caspase-2 activity by small molecule probes leads to the amelioration of disease
phenotype, initially in animal models. Our specific aims all target the discovery and development of caspase-2
probes but each has a different starting point. We will use measurement of ∆tau314 levels, a specific
therapeutically- and clinically-relevant biomarker, as part of our testing funnel, to gauge the efficacy of our probes
in cells. Our probe design and development will feature three parallel paths of compound characterization and
optimization, each of which will inform the other as to caspase-2 binding that influences specificity and potency.
Our three aims are to develop (1) probes from proteins that are specifically cleaved by caspase-2, (2) probes
from HTS follow-on, and (3) probes from known selective caspase-2 inhibitors. Our goal in each of these is to
produce a probe or tool compound which has in vitro potency 30-fold
selectivity relative to sequence-related targets in the same family, has been profiled against an “industry-
standard” panel of pharmacologically-relevant off-targets, and has demonstrated on-target effect in cells of
