Biochem/physiol Actions

Extrasynaptic eNMDAR-selective blocker (over synaptic sNMDAR) with improved efficacy than memantine in cultures and in vivo; potent inhibitor of the SARS-CoV-2 virus entry.
NitroSynapsin is an NMDAR blocker that preferentially targets extrasynaptic over synaptic NMDA receptors (eNMDAR over sNMDAR) via a dual allosteric mechanism of open-channel blockage and NO/redox modulation. NitroSynapsin is significantly more effective than memantine (5 µM) in inhibiting the activation of rat cotical neurons due to NMDA release from co-cultured astrocytes upon stimulation by Aβ1-42 oligomers. When administered in the triple transgenic (3× tg) AD mouse model in vivo (216 mmol/kg bid. ip.), NitroSynapsin, but not memantine, significantly improves the location-novelty recognition. It is a potent inhibitor of the SARS-CoV-2 virus entry that prevents the virus spike protein binding to ACE2 (angiotensin-converting enzyme 2).

Tuberous sclerosis (TSC) is an autosomal dominant disorder caused by heterozygous mutations in the TSC1 or TSC2 gene. TSC is often associated with neurological, cognitive, and behavioral deficits. TSC patients also express co-morbidity with anxiety and mood disorders. The mechanism

Prevention of infection and propagation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a high priority in the Coronavirus Disease 2019 (COVID-19) pandemic. Here we describe S-nitrosylation of multiple proteins involved in SARS-CoV-2 infection, including angiotensin-converting enzyme 2 (ACE2)

Synaptic loss is the cardinal feature linking neuropathology to cognitive decline in Alzheimer's disease (AD). However, the mechanism of synaptic damage remains incompletely understood. Here, using FRET-based glutamate sensor imaging, we show that amyloid-β peptide (Aβ) engages α7 nicotinic acetylcholine
