Diethylhomospermine is a polyamine analogue with antiproliferative and potential anti-diarrheal activities. Diethylhomospermine (DEHSPM) antagonizes polyamine activity via NMDA receptor glutamine binding site, thereby modulating inotropic stasis and reducing stool volume (anti-diarrhea). However, due to the toxic effects from metabolites of DEHSP, other tetramine derivatives with less toxicity have been developed.
