Our research emphasis pertains to natural toxins which interact specifically with receptor Site 1 (saxitoxin and tetrodotoxin), Site 2 (batrachotoxin, veratridine, and aconitine), and Site 5 (brevetoxins and ciguatoxin) associated with voltage-sensitive sodium channels. Our current molecular pharmacology work requires derivatization of each of these classes of toxin for use in biochemical investigations of the binding phenomena. Computer modeling of proposed derivatives, including structure-function relationships between receptor and toxin ligand, aids in our efforts to describe the 3-dimensional characteristics of each toxin binding site. A second avenue of research pertains to the development of specific binding assays for marine seafood toxins, with the express end product being colorometric detection kits for public health use. Current work centers on preparing immunological reagents for assay development, with future aspects involving the specific membrane-bound toxin receptor in in vitro microtitre plate formats and biosensor technology.
