suramin is an approved drug

Comment: Suramin is an antiparasitic drug. It is also used in research as a broad-spectrum P2 receptor antagonist [1,5] and as a ryanodine receptor agonist [13].
Evidence from studies in mice [7-9], and from an early phase clinical trial suggest antipurinergic therapy (using suramin or other antipurinergic compounds) as a potential lead in the search for pharmacotherapeutic intervention in children with autism spectrum disorder (see Phase 1/2 clinical trial NCT02508259).
