Project Details
Description
The overall goal of the current research is to develop a novel class of therapeutics that will mitigate mortality
and morbidity caused by acute exposure to parathion, an organophosphate (OP) insecticide that is considered
a high priority chemical threat. The toxicity of parathion is dependent on its metabolism by the cytochrome
P450 system to an active metabolite, paraoxon. By inhibiting P450-mediated generation of paraoxon,
progressive toxicity can be reduced. Ongoing research in our laboratory in the field of redox chemistry has led
to the identification of a candidate therapeutic that is a highly effective inhibitor of the P450 system. This drug,
which has very low toxicity, is currently undergoing advanced clinical trials for other diseases and has been
approved by the FDA for other indications. In 'proof-of-concept' studies, we have generated strong data
showing that our drug is highly effective in reducing parathion toxicity. We have partnered with a company that
has a drug product containing our candidate therapeutic in phase 1/phase 2 clinical trials. Our aims are to
assess the ability of this drug product to inhibit bioactivation of parathion and reduce parathion toxicity in the rat
model, conduct preclinical IND-enabling studies for the drug product for use in OP poisoning, and determine if
the drug product can enhance the therapeutic actions of currently used drugs that are the standard of care in
the treatment of OP toxicity. Success of this proposal may lead to the rapid development of a new agent to
treat human exposure to a high priority chemical threat. Use of an FDA approved drug will greatly reduce the
time required for regulatory approval.
