Biological Activity
IC50: 50 nM (the binding of [3H]-3-(2-carboxypiperazin-4-yl)propyl-1-phosphonic acid to NMDA-type receptors)[2].
Selfotel (CGS 19755) results in a concentration-dependent reduction in neuronal death as assessed by phase-contrast microscopy and by measurement of LDH release into the bathing medium 20-24 h later. The mean (±SD) ED50 for CGS 19755 against NMDA toxicity is 25.4 ± 30.8 μM, determined from 6 experiments, each using 4 cultures per condition[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Selfotel (CGS 19755) significantly increases conflict responding within a relatively narrow dose range (minimum effective dose, 1.73 mg/kg i.p.)[1].
Selfotel (CGS 19755) blocks the harmaline-induced increase in cerebellar cyclic GMP levels at a dose of 4 mg/kg i.p. with duration of action exceeding 2 hr[2].
Selfotel (CGS 19755) inhibits convulsions elicited by maximal electroshock in rat (ED50 = 3.8 mg/kg i.p. 1 hr after administration) and in mouse (ED50 = 2.0 mg/kg i.p. 0.5 hr after administration)[2].
