Discovery of diaminobutane derivatives as Ca(2+)-permeable AMPA receptor antagonists.

We designed and synthesized a series of the polyamine derivatives as potent Ca(2+)-permeable AMPA receptor antagonists. In the course of this study, we found that the polyamine derivatives exhibited strong hypotensive activity which was undesirable activity for neuroprotective agents. Therefore, we tried to find non-hypotensive antagonists by structural modification of such compounds. Through this derivatization, we obtained the diamine compounds having desired profiles. Especially, compound 8f, which was non-hypotensive and potent Ca(2+)-permeable AMPA receptor antagonist, showed neuroprotective effects in transient global ischemia models in gerbils.

Synthesis of polyamine derivatives having non-hypotensive Ca2+-permeable AMPA receptor antagonist activity

In order to obtain non-hypotensive and Ca2+-permeable AMPA receptor antagonists, we have synthesized a series of 1,4-bis(4-piperidinylmethyl)diaminobutanes. Compounds 13b, c, f had desirable properties.
