Design, total synthesis, and biological evaluation of neodysiherbaine A derivative as potential probes

To enable studies to elucidate the detailed biological function of dysiherbaine and neodysiherbaine A, potent and subunit-selective agonists for ionotropic glutamate receptors, the derivative with a hydroxymethyl substituent at the C10 position has been developed. Preliminary biological evaluation of the analogue showed that a C10 hydroxymethyl substituent produced significant alterations in binding affinities for the ionotropic glutamate receptor subtypes.
