Tulrampator
Tulrampator (developmental code names S-47445, CX-1632) is a positive allosteric modulator (PAM) of the AMPA receptor (AMPAR), an ionotropic glutamate receptor, which is under development by RespireRx Pharmaceuticals (formerly Cortex Pharmaceuticals) and Servier for the treatment of major depressive disorder (as an adjunct), Alzheimer's disease, dementia, and mild cognitive impairment. Tulrampator was in phase II clinical trial for depression, but failed to show superiority over placebo.https://clinicaltrials.servier.com/wp-content/uploads/CL2-47445-014-synopsis-report.pdf There are also phase II clinical trials for Alzheimer's disease and phase I trials for dementia and mild cognitive impairment. Tulrampator is a "high-impact" AMPAR potentiator, unlike "low-impact" AMPAR potentiators like CX-516 and its congener farampator (CX-691, ORG-24448), and is able to elicit more robust increases in AMPAR activation. In animals, high-impact AMPAR potentiators enhance cognition and me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AMPA Receptor
The α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (also known as AMPA receptor, AMPAR, or quisqualate receptor) is an ionotropic receptor, ionotropic transmembrane receptor for glutamate (iGluR) that mediates fast synapse, synaptic transmission in the central nervous system (CNS). It has been traditionally classified as a non-NMDA_receptor, NMDA-type receptor, along with the kainate receptor. Its name is derived from its ability to be activated by the artificial glutamate analog AMPA. The receptor was first named the "quisqualate receptor" by Watkins and colleagues after a naturally occurring agonist quisqualic acid, quisqualate and was only later given the label "AMPA receptor" after the selective agonist developed by Tage Honore and colleagues at the Royal Danish School of Pharmacy in Copenhagen. The ''GRIA2''-encoded AMPA receptor ligand binding core (GluA2 LBD) was the first glutamate receptor ion channel domain to be protein crystal, crystallized. Structure ...
