It selectively targets the AMPA receptor, showing high affinity (IC₅₀ = 0.043 μM) and competitive inhibition of AMPA-induced effects in rat cortical membranes and cultured mouse cortical neurons. In vivo, SPD-502 effectively blocks AMPA-evoked spike activity in the hippocampus after intravenous administration, significantly increasing the seizure threshold in mice and demonstrating robust protection against ischemia-induced damage to hippocampal neurons in gerbils. These findings suggest SPD-502 may be promising for treating neurodegenerative conditions associated with glutamate excitotoxicity .

Cuproptosis Compound Library	217 compounds
Copper is an important co-factor of all biological enzymes, but if the concentration exceeds the threshold of maintaining the homeostasis mechanism, copper will lead to cytotoxicity. This death mechanism has been named "Cuproptosis". The mechanism of cuproptosis distinct from all other known mechanisms of regulated cell death, including apoptosis, pyroptosis, necroptosis, and ferroptosis. Copper combine with the lipoylated components of the tricarboxylic acid cycle (TCA), leading to lipoylated protein aggregation and subsequent loss of iron-sulfur cluster proteins, ultimately resulting in protein toxicity stress and cell death. Studies have shown that the necessary factors for cuproptosis include the presence of glutathione, mitochondrial metabolism of galactose and pyruvate, and glutamine metabolism. Targeted regulation of cuproptosis is a potential choice to treat cancer, rheumatoid arthritis, and other diseases. For example, up-regulation of LIPT1 may inhibit the occurrence and development of tumors by destroying TCA in mitochondria and then inducing cuproptosis. MCE supplies a unique collection of 217 cuproptosis-related compounds, all of which act on the targets or signaling pathways related to cuproptosis and may have in inhibitory or activated effect on cuproptosis. MCE Cuproptosis Library is a useful tool for drug research related to cancer, rheumatoid arthritis, and other diseases.
