Biological Data
| Biological description | Overview Selective, ultrapotent PSEM agonist for PSAM4-GlyR and PSAM4-5HT3 (Ki values are 0.15 nM and and EC50 = 0.3 nM at PSAM4-GlyR) which can be used for targeted control of brain activity in rodent and primate models. It has excellent selectivity with 5000- to 10,000-fold selectivity for PSAM4-GlyR over α-7-GlyR, α7-5HT3R and 5-HT3R. It also does not show evident α4β2 nAChR agonism up to 30 µM. It does not act as a P-glycoprotein pump (PgP) substrate. Uses and applications It strongly suppresses layer 2/3 cortical neurons expressing PSAM4-GlyR in brain slices at low concentrations (ranging from 1-15 nM). |
