Anesthetic development has remained a largely empirical process. There are growing concerns about the cognitive effects of known general anesthetics  and acceleration of the onset of neurodegenerative disease . The compounds' toxicity  and multiple specific binding targets in the mammalian brain  has made them less attractive as drug leads.
In the primary screen for this project, a GABAergic mimetic model system, apoferritin and a profluorescent 1-aminoanthracene ligand (1-AMA), is used to construct a competitive binding assay for identification of novel general anesthetics , .
This project is currently ongoing. Additional details of follow-up assays and results will be summarized here in future updates.
