Ditolylguanidine is a sigma receptor agonist.[1] It is somewhat[2] selective for sigma receptors, but non-selective between the two sigma receptor subtypes, binding to both σ1 and σ2 with equal affinity.[3] It has neuroprotective[4] and antidepressant effects,[5] and potentiates the effects of NMDA antagonists.[6]
