Rapastinel acetate
Based on 1 publication(s) in Google Scholar
Rapastinel (GLYX-13) acetate is a potent NMDAR modulator capable of crossing the blood-brain barrier, and it exhibits extremely high affinity for human NMDAR (EC50=0.0017-9.9 nM). Rapastinel acetate enhances ERK signaling and activates the mTOR pathway, thereby upregulating the expression of BDNF and VGF, and inducing significant neuroplastic changes such as enhanced LTP and increased mature dendritic spine density in the hippocampus. Rapastinel acetate moderately elevates the efflux of dopamine, norepinephrine and 5-HT in the prefrontal cortex, and uniquely avoids side effects of traditional antidepressants such as dissociation, addiction or sedation. Rapastinel acetate is applicable to the research of major depressive disorder and hepatocellular carcinoma.

Biological Activity
Rapastinel acetate (20 μM; 4 h) reverses the propofol-induced reductions in CaMKII phosphorylation, AKT phosphorylation, HIF-1α expression, intracellular Ca2+ concentration, glycolysis protein levels, adhesion molecule levels, and tumor cell-endothelial cell adhesion in Huh7 tumor conditioned medium-treated HUVECs[2].
Rapastinel acetate (tested concentrations; 15 min preincubation, 15 min with [3H] MK-801) partially enhances [3H] MK-801 binding to recombinant human NR2A-, NR2B-, NR2C-, and NR2D-containing NMDARs with EC50 values of 9.8 pM, 9.9 nM, 2.2 pM, and 1.7 pM, respectively[5].
Rapastinel acetate (100 nM-1 μM) has its modulatory effects on NMDAR-mediated calcium mobilization completely abolished by mutations of critical amino acids in the NR2A(R392E) or NR2B(R393E) NMDAR amino terminal domain, confirming this domain is required for rapastinel's activity[5].

A single intravenous administration of Rapastinel (3 mg/kg) acetate produces sustained antidepressant-like and anxiolytic-like effects in male Sprague-Dawley rats for at least 1 week, as evidenced by significant changes in ultrasonic vocalizations, time spent in the central zone of the open field test, and immobility time in the Porsolt forced swim test. It also induces sustained cognitive-enhancing effects, as reflected by improved behavioral performance of rats in spontaneous alternation, positive affective learning, Morris water maze, and contextual fear extinction tests[3].
Rapastinel (1 mg/kg; subcutaneous injection; twice daily; administered for 3 or 5 days) acetate reverses subchronic Phencyclidine-induced novel object recognition (NOR) impairment for at least 9 or 10 weeks, respectively, whereas Rapastinel (1 mg/kg; subcutaneous injection; 30 minutes in advance; single dose) acetate only transiently reverses NOR function when the test interval is 24 hours[4].
Rapastinel (10-30 mg/kg; subcutaneous injection; single administration) acetate produces rapid and sustained antidepressant-like effects in rats, corresponding to concentrations of approximately 30 nM and ~100 nM in the medial prefrontal cortex (mPFC), respectively[5].

Calpain-2 plays a pivotal role in the inhibitory effects of propofol against TNF-α-induced autophagy in mouse hippocampal neurons. [Abstract]2020 Aug;24(16):9287-9299. PMID: 32627970
Rapastinel acetate purchased from MedChemExpress. Usage Cited in: J Cell Mol Med. 2020 Aug;24(16):9287-9299. [Abstract]
Neurons are pre-treated with 25 μM propofol plus 20 μM Rapastinel, followed by TNF-α treatment (40 ng/mL, 2 h). The effect of propofol on TNF-α- induced intracellular calcium accumulation, phosphorylation of CaMK II and calpain-2, calpain activation, cathepsin B release and TrkB truncation is counteracted by Rapastinel.
