Abstract

This Letter describes the natural product guided synthesis of unnatural analogs of the marine bromopyrrole alkaloid dispyrin, and the resulting SAR of H(3) antagonism. Multiple rounds of iterative parallel synthesis improved human H(3) IC(50) approximately 33-fold, and afforded a new class of H(3) antagonists based on the novel bromotyramine core of dispyrin.
