Suramin
SOO-rah-min
A century-old antiparasitic drug being re-explored for its ability to modulate purinergic signaling — a pathway linked to autism and immune function.
Also known as: Germanin
Last reviewed: April 2026
What It Does
Suramin was developed in 1916 for African sleeping sickness. Recent research has discovered it blocks purinergic receptors (P2X and P2Y) — part of the 'cell danger response.' This has generated interest in autism spectrum disorder (ASD) research, where a small trial showed temporary symptom improvement, and in immune/mitochondrial function.
