Baclofen
Based on 13 publication(s) in Google Scholar
Baclofen, a lipophilic derivative of γ-aminobutyric acid (GABA), is an orally active, selective metabotropic GABAB receptor (GABABR) agonist with blood-brain barrier permeability. Baclofen mimics the action of GABA and produces slow presynaptic inhibition through the GABAB receptor. Baclofen has high blood brain barrier penetrance. Baclofen has the potential for muscle spasticity research.

Baclofen (1, 10 μM; 24 h) causes markedly decreased lactate dehydrogenase (LDH) activity, indicating increased cell viability in wild-type or mutant huntingtin-expressing striatal cells (HD19 or HD43). Baclofen significantly increases chymotrypsin-like proteasome activity and cell viability were in the HD43 cells[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Baclofen can cross the blood-brain barrier and cause depressive effects[4].
Note that the water solubility of Baclofen makes it difficult to cross the blood-brain barrier (BBB) ??after oral administration, so higher doses may be required in practice[5].

Baclofen purchased from MedChemExpress. Usage Cited in: Antioxidants (Basel). 2024 Sep 21;13(9):1141. [Abstract]
The mRNA levels of IL-1β, IL-6, and TNF-α were measured by qRT-PCR in the CON, LPS, and LPS + Baclofen (100 μM; 12 h) groups. Baclofen pretreatment led to a considerable diminution in these proinflammatory factors, suggesting that activating GABABR in IPEC-J2 cells exerts anti-inflammatory actions.
