The terrestrial organisms Streptomyces venezuelae and Rhaponticum repens produce toxic secondary metabolites that likely function as chemical deterrents. The polyketide SV-6 from S. venezuelae and the sesquiterpene lactone repin from R. repens both produce dose-dependent and selective degeneration of dopaminergic neurons. These molecules represent two possible tools that can be used to explore chemotoxic induction of Parkinson’s disease. In the case of SV-6, a newly isolated metabolite, total synthesis was undertaken to confirm its structure and biological activity. The natural product was produced from methacrolein and Roche ester starting materials that were elaborated to their respective fragments, a vinyl iodide …

An estimated 13.9% of Americans currently meet criteria for an alcohol (ethanol; EtOH) use disorder (AUD). While there are 4 medications approved by the Food and Drug Administration (FDA) to treat AUD, these treatments have demonstrated poor clinical efficacy. Our ongoing research program encompasses a multi-tiered screening of a natural product library and validation process to provide novel information about the mechanisms underlying EtOH-induced changes in neurobiology and to identify novel chemical scaffolds to be exploited in the development of pharmacological treatments for AUD in a rodent organotypic hippocampal slice culture model. Initial screens of several natural product compounds identified …
