Letter describes the natural product guided synthesis of unnatural analogs of the marine bromopyrrole alkaloid dispyrin, and the resulting SAR of H3 antagonism. Multiple rounds of iterative parallel synthesis improved human H3 IC50 ∼33-fold, and afforded a new class of H3 antagonists based on the novel bromotyramine core of dispyrin.
