Preferential Synaptic Type of GABA-A Receptor Ligands Enhancing Neuronal Survival and Facilitating Functional Recovery After Ischemic Stroke.

Selective enhancement of synaptic GABA signaling mediated by GABA-A receptors has been previously reported to promote functional recovery after ischemic stroke, while tonic GABA signaling has been detrimental. To identify agents that enhance synaptic signaling, we synthesized GABA-A ligands based on three chemotypes with affinity values p= 6.44-8.

The psychoplastogens ibogaminalog and ibogainalog induce antidepressant-like activity in naïve and depressed mice by mechanisms involving 5-HT receptor activation and serotonergic transmission.

The antidepressant-like activity of two psychoplastogens, ibogainalog (IBG) and ibogaminalog (DM506), was studied in naïve mice using the forced swim test (FST) and tail suspension test (TST). The behavioral results showed that a single administration of 25 mg/kg DM506 or 10 mg/kg IBG induced antidepressant-like activity in naïve mice in a volinanserin-sensitive manner that persisted for 72 h. Similar results were observed using the chronic immobilization stress (CIS) test, in which depression symptoms were reduced for 48 h.
