Abstract:
Methods for using exogenous fluorophore and general anesthetic 1-aminoanthracene (1-AMA) and its photoactive derivative 1-azidoanthracene (1-AZA) are provided. 1-AMA potentiates GABAA chloride currents and immobilizes Xenopus laevis tadpoles. Cellular and tissue anesthetic distribution can be imaged for quantifying "on-pathway" and "off-pathway" targets. 1-AZA shares targets with 1-AMA and offers further optoanesthetic spatial and temporal control upon near-UV laser irradiation. Furthermore, 1-AZA adduction provides screening of possible relevant anesthetic protein targets and binding site characterization. We highlight several useful imaging and binding assays to demonstrate utility of 1-AMA and its derivative 1-AZA.

Local Anesthetics: Mechanism of Action
Local anesthetics are amphiphilic molecules consisting of a hydrophobic aromatic part linked to a hydrophilic group by an ester or amide linkage. They are weak bases and are usually available as salts, which increases their solubility and stability. Once administered, LAs exist in the body either...

Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...
