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.

Technical Specifications

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.
