DQP-997-74 (compound 2i) is a selective inhibitor of N-metl-d-aspartate receptor (NMDAR), specifically targeting GluN2C/D (IC50: 0.069 μM and 0.035 μM), with blood-brain barrier penetrability. Where DQP refers to didroquinoline-pyrazoline. DQP-997-74 acts synergistically with the agonist glutamate to exhibit time-dependent enhanced potency in inhibiting persynchronous activity driven by high-frequency excitatory synaptic transmission. DQP-997-74 reduces the number of epileptogenesis in a murine model of tuberous sclerosis complex (TSC)-induced epilepsy. DQP-997-74 can be used for research on NMDAR-related neurological diseases.
