HBT1 (YDL233C) Overview
HBT1, also known by the screening identifier YDL233C, is a synthetic small-molecule AMPA receptor positive allosteric modulator. The YDL233C label originates from internal compound indexing during early screening and does not indicate yeast origin or biological derivation.
HBT1 has been studied in laboratory research for its ability to potentiate AMPA-type glutamate receptor (AMPAR) activity, making it a compound of interest in neuroscience research related to excitatory synaptic transmission and synaptic plasticity.
HBT1 is not approved for human or veterinary use and is supplied strictly for laboratory and analytical research purposes.
Mechanism of Action
HBT1 functions as a positive allosteric modulator of AMPA receptors. It enhances glutamate-mediated AMPAR signaling without acting as a direct agonist. In research models, this results in:
-
Increased AMPA receptor–mediated synaptic currents
-
Prolonged receptor open time
-
Enhanced excitatory neurotransmission
This mechanism places HBT1 within the broader class of AMPAkine-like compounds, though it represents a distinct chemical scaffold.
