HBT1 (YDL233C)
HBT1 (YDL233C)
HBT1, also recognized by its screening identifier YDL233C, is a synthetic small-molecule AMPA receptor positive allosteric modulator. The designation YDL233C stems from internal compound indexing during early developmental screenings and does not indicate a yeast origin or any biological derivation. In neuroscience and neuropharmacology research, HBT1 is widely used as a tool compound to investigate the mechanics of excitatory synaptic transmission, cognitive signaling pathways, and long-term potentiation (LTP) models.

Mechanism of Action & Research Utility
HBT1 functions specifically as a positive allosteric modulator of AMPA-type glutamate receptors (AMPAR). Rather than operating as a direct agonist, it amplifies endogenous, glutamate-mediated AMPAR signaling. This distinct heterocyclic scaffold allows investigators to explore targeted receptor-ligand interactions and central nervous system penetration dynamics in experimental models.
In controlled laboratory settings, this allosteric interaction results in:
-
Increased AMPA receptor-mediated synaptic currents.
-
Prolonged receptor open time dynamics.
-
Enhanced excitatory neurotransmission without direct receptor overstimulation.
Research Focus Areas
As a reference standard for synaptic plasticity, HBT1 is primarily examined across several in vitro and laboratory research applications:
-
AMPA Receptor Modulation: Mapping the precise binding pockets and structural kinetics associated with allosteric AMPAkine modulation.
-
Excitatory Synaptic Transmission: Measuring baseline adjustments in synaptic strength and neurotransmitter responses.
-
Synaptic Plasticity & LTP Models: Using the compound to establish cellular baselines for long-term potentiation and synaptic remodeling studies.
-
Neuropharmacology Research: Investigating small-molecule pathways linked to cognitive signaling and neurochemical communication.
Storage & Handling Guidelines
Store at controlled room temperature. Keep tightly closed. Liquid formats: do not refrigerate or freeze. Cold storage may cause the solution to cloud or precipitate. If this occurs, return to room temperature and mix until clear.
Storage guidance is a house recommendation. Analytical documentation is per-lot release testing.
