ZJ43
Based on 1 Customer Validation
ZJ43 is a NAAG peptidase inhibitor and glutamate carboxypeptidase II/III (GCP II/III) inhibitor with human GCP II IC50 of 2.4 nM and Ki of 0.8 nM. ZJ43 blocks N-acetylaspartylglutamate hydrolysis, elevates extracellular N-acetylaspartylglutamate levels, and activates group II metabotropic glutamate receptors (mGluR). ZJ43 can be used for the research of schizophrenia, inflammatory pain, neuropathic pain, and traumatic brain injury.

ZJ43 (range sufficient to generate dose-response curves; 2 h) potently inhibits cloned human GCP II with a Ki of 0.8 nM[1].
ZJ43 (range sufficient to generate dose-response curves) inhibits cloned mouse GCP III with a Ki of 23 nM[1].
ZJ43 (2 h) inhibits cloned rat GCPII with a Ki of 3 nM[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
ZJ43 (10-100 mg/kg; i.v.; single dose) produces dose-dependent analgesia in the rat Formalin inflammatory pain model[3].
ZJ43 (10-100 mg/kg; i.v.; single dose) produces dose-dependent antiallodynic effects in the rat partial sciatic nerve ligation neuropathic pain model[3].
ZJ43 (100 mg/kg; i.v.; single dose) does not alter acute nociceptive responses to noxious mechanical or thermal stimulation in healthy rats[3].
ZJ43 (50-150 mg/kg; i.p.; every 8 h; 3 total doses) significantly reduces ipsilateral neuronal degeneration in rat lateral fluid percussion TBI[4].

Animal Model:Sprague-Dawley (male, 280-330 g, PCP-induced schizophrenia-like symptoms)[1]
-
Dosage:150 mg/kg
-
Administration:i.p.; single dose
-
Result:Significantly reduced PCP-induced motor activity, with a statistically significant difference in total distance traveled between 80-180 min compared to PCP-only treated rats (p = 0.021).
Significantly increased the frequency of rats being "still" (p = 0.015).
Significantly reduced PCP-induced stereotypic falling (p = 0.02), circling movements (p ≤ 0.001), total head movements (p = 0.005), and head bobbing (p = 0.004) compared to PCP-only treated rats.
Produced a non-statistically significant trend toward reduced PCP-induced mouth movements, tremors, and sideways head movements.
Failed to reduce PCP-induced sniffing and showed a non-significant tendency to increase this behavior (p = 0.17).

Animal Model:Rats (Formalin-induced inflammatory pain model)[3]
-
Dosage:10 mg/kg; 100 mg/kg
-
Administration:i.v.; single dose
-
Result:Decreased cumulative formalin-evoked flinches in both phase 1 (0-6 minutes) and phase 2 (10-60 minutes) in a dose-dependent manner (phase 1 P < 0.005, phase 2 P < 0.001).
Reduced flinching to ~50% of vehicle response in phase 1 and ~30% of vehicle response in phase 2 at 100 mg/kg.
-
Animal Model:Rats (partial sciatic nerve ligation neuropathic pain model)[3]
-
Dosage:10 mg/kg; 100 mg/kg
-
Administration:i.v.; single dose
-
Result:Significantly increased the maximum 50% probability mechanical withdrawal threshold in a dose-dependent manner (P < 0.001).
Elevated the threshold to ~13 g at 100 mg/kg (compared to ~2 g in saline-treated rats).
-
Animal Model:Rats[3]
-
Dosage:100 mg/kg
-
Administration:i.v.; single dose
-
Result:Had no significant effect on the number of paw withdrawal responses to noxious mechanical stimulation, with maximum responses (18.8) and minimum responses (15.6) not differing significantly from saline-treated rats (P > 0.3).
Had no significant effect on hotplate response latency, with % maximum possible effect (-9.9) not differing significantly from saline-treated rats (P > 0.8).

Animal Model:Sprague-Dawley (male, 340 g, lateral fluid percussion TBI moel)[4]
-
Dosage:50 mg/kg; 100 mg/kg; 150 mg/kg
-
Administration:i.p.; every 8 h; 3 total doses
-
Result:Significantly reduced the number of ipsilateral degenerating neurons in the hippocampal CA2/3 regions compared to vehicle (p < 0.01).
Reduced ipsilateral astrocyte loss to 14.0% versus 30.6% in the vehicle group at 50 mg/kg dose (p = 0.05; p = 0.007).
