HBT1

HBT1 is an AMPA receptor potentiator that induces production of brain-derived neurotrophic factor (BDNF) and exhibits little agonistic effect in primary neurons. HBT1 binds to ligand-binding domain of AMPA-R in glutamate dependent manner.HBT1 bound to the ligand-binding domain (LBD) of AMPA-R in a glutamate-dependent manner. The mode of HBT1 and LY451395 binding to a pocket in the LBD of AMPA-R differed: HBT1, formed hydrogen bonds with S518 in the LBD. Lower agonistic profile of HBT1 may associate with its lower risks of bell-shaped responses in BDNF production in primary neurons.
