Rapastinel (Trifluoroacetate)

Rapastinel Trifluoroacetate (GLYX-13 Trifluoroacetate) is an NMDA receptor modulator with glycine-site partial agonist properties. Rapastinel Trifluoroacetate has the potential for major depressive disorder treatment. IC50 & Target: NMDA receptor^[1] In Vivo: Rapastinel Trifluoroacetate is an NMDA receptor modulator with glycine-site partial agonist properties and currently in a phase II clinical development program as an adjunctive therapy for major depressive disorder. Mice given Rapastinel Trifluoroacetate (1.0 mg/kg) prior to acute ketamine (30 mg/kg) show clear preference for novel compare to familiar objects (P<0.01)^[1]. Rapastinel Trifluoroacetate produces an antidepressant like effect in the USVs test, as indexed by an increase in hedonic 50-kHz USVs [F(1,20)=12.4, P<0.05] and a decrease in aversive 20-kHz USVs [F(1,20)=6.8, P<0.05]. Rapastinel Trifluoroacetate also produces an anxiolytic effect in the open field, as indexed by increased center time [F(1,20)=19.2, P<0.05] without altering locomotor activity as measured by line crosses [F(1,20)=0.0, P>0.05]^[2].
