(S)-3,4-DCPG
Based on 1 Customer Validation
(S)-3,4-DCPG ((S)-3,4-Dicarboxyphenylglycine) is a potent and selective mGlu8a receptor agonist with an EC50 of 31 nM for human mGlu8a. (S)-3,4-DCPG inhibits Forskolin (HY-15371)-stimulated cAMP formation by activating mGlu8, and modulates presynaptic glutamatergic transmission and synaptic plasticity. (S)-3,4-DCPG can be used in research on inflammatory pain, neuropathic pain, autism spectrum disorder, and glutamatergic synaptic plasticity.

In Vitro
(S)-3,4-DCPG ((S)-3,4-Dicarboxyphenylglycine) (≤ 100 μM) selectively activates mGlu8a in RGT (AV12-664) cells expressing human mGlu1-8, and inhibits forskolin-stimulated cAMP formation. It has an EC50 of 31 nM for mGlu8a, while the EC50 values for mGlu4a, mGlu6 and mGlu7a are 8.8 μM, 3.6 μM and > 100 μM, respectively, demonstrating its selectivity for mGlu8a[1].
(S)-3,4-DCPG (0.5-400 μM; 5 min) inhibits the fast component of dorsal root-evoked ventral root potential (fDR-VRP) in spinal cord preparations from neonatal rats, producing a biphasic concentration-response curve. The EC50 values of the high-affinity and low-affinity components are 1.3 μM and 391 μM, respectively, with the high-affinity component mainly mediated by mGlu8[1].

In Vivo
(S)-3,4-DCPG (30 or 60 mg/kg; 15 min prior to carrageenan; i.p.) increases the thermal withdrawal latency and mechanical withdrawal threshold in the carrageenan (HY-125474) inflammatory pain model, whereas administration of (S)-3,4-DCPG at 1 h after carrageenan treatment exerts no significant effect[2].
(S)-3,4-DCPG (60 mg/kg; single dose; i.p.) increases paw withdrawal latency to heat and mechanical paw withdrawal threshold on day 3 after chronic constriction injury of the sciatic nerve, thereby alleviating thermal hyperalgesia and mechanical allodynia, but exerts no significant effect on day 7 post-injury[2].
(S)-3,4-DCPG (1 μM/0.5 μL per side; intra-DG) reverses the reduced social novelty preference index (SNPI) in prenatal VPA-induced Wistar rat models of autism, and enhances fEPSP LTP in the PP-DG pathway of VPA-exposed rats, while inhibiting LTP in normal control rats[3].

Formalin-Induced Paw Inflammation/Nociceptive Inflammation
The formalin-induced paw inflammation/nociceptive test is a chemical persistent pain model in rodents in which subcutaneous injection of formalin into the hind paw produces spontaneous nocifensive behaviors such as flinching and licking. The response is classically biphasic, consisting of an early acute phase (Phase I) reflecting direct activation of peripheral nociceptors (particularly C-fiber afferents), followed by a later prolonged phase (Phase II) associated with central sensitization in the spinal dorsal horn driven by sustained afferent input and inflammatory signaling. This model is widely used to evaluate analgesic and anti-inflammatory interventions because it captures both peripheral nociception and central sensitization processes within a single assay system.
