nerve injury

Adenosine A1 receptor activator T62 is an allosteric enhancer of the adenosine A1 receptor, producing antinociception in animal models of acute pain and reducing hypersensitivity in models of inflammatory and nerve-injury pain[1][2][3].

Bellidifolin (Bellidifoline) has anti-oxidation, hepatoprotective, anti-inflammatory and antitumor actions, it may contribute to the protective effects associated with nerve injury initiated by hypoxia by mechanisms related to inhibition of cell apoptosis independent of the ERK pathway. Bellidifolin shows interesting inhibitory activity of monoamine oxidases (MAO) A, it could be useful for treating type-2 diabetes, likely via the improvement of insulin resistance (IR). Bellidifolin also shows an antifungal effect (MIC values of 50 microg/mL).

LP-935509 is a selective, brain-permeable, small molecule competitive inhibitor of articulin-2-associated kinase 1 (AAK1) with an IC50 of 3.3 nM and a Ki of 0.9 nM. LP-935509 is a potent inhibitor of BIKE (IC50 of 14 nM) and a moderate inhibitor of GAK (IC50 of 320±40 nM).

The P7C3 class of neuroprotective aminopropyl carbazoles has been shown to block neuronal cell death in models of neurodegeneration. We now show that P7C3 molecules additionally preserve axonal integrity after injury, before neuronal cell death occurs, in

ASP8477 is a potent and selective FAAH inhibitor. It increases anandamide levels in the brain when administered orally. In rat models of neuropathic and osteoarthritic pain, ASP8477 demonstrates significant efficacy without causing motor coordination issues. A single oral dose of ASP8477 improves thermal hyperalgesia and cold allodynia in rats with chronic constriction nerve injury. Moreover, ASP8477 restores the decreased muscle pressure threshold in a myalgia model induced by reserpine. Research indicates that ASP8477 possesses analgesic effects effective for alleviating neuropathic and functional pain, making its pharmacological properties suitable for chronic pain treatment.

LY-266097, a selective 5-HT2BR antagonist, effectively reduces tactile hypersensitivity and demonstrates potential therapeutic effects in alleviating pain caused by nerve injury. Additionally, it decreases the upregulation of 5-HT2B receptors in the dorsal root ganglia and spinal cord following nerve damage. Research indicates that LY-266097 may play a potential role in the development of neuropathic pain pathways.

UKH-1114 is a potent σ2 receptor Tmem97 agonist with a Ki value of 46 nM, demonstrating antinociceptive effects against mechanical hypersensitivity. This compound alleviates mechanical hypersensitivity in mice caused by nerve injury without inducing motor impairment and is a promising candidate for neuropathic pain research.

HW161023 (compound) is an orally active inhibitor of AP2 associated protein kinase 1 (AAK1), exhibiting IC50 values of 5.4 nM for AAK1 and 11.9 μM for hERG. HW161023 can suppress pain response in a rat model of chronic sciatic nerve compression injury.

VU0155041 sodium is a positive allosteric modulator of mGluR4, promoting extinction in male rats and inhibiting the recovery of morphine-induced conditioned place preference. It alleviates hyperalgesia in nerve injury pain models, useful in neurodegenerative disease research.

JHU-58 is a novel dipeptide MrgC agonist. JHU-58 inhibited both mechanical and heat hypersensitivity in rats after an L5 spinal nerve ligation (SNL). JHU58 attenuated the evoked excitatory postsynaptic currents in substantia gelatinosa (SG) neurons in wild-type mice, but not in Mrg knockout mice, after peripheral nerve injury.

Melanotan II acetate is an agonist of melanocortin receptor 1 (MC1R), MC3R, MC4R, and MC5R. It has been shown to improve recovery of sciatic nerve function after mechanical injury and increase cisplatin-induced decreases in sensory nerve conduction velocity. Melanotan II acetate increases oxygen consumption and protein levels of uncoupling protein 1 (UCP1) in brown adipose tissue homogenates and decreases food intake, body weight, and serum levels of leptin, glucose, insulin, and cholesterol.

SRI-42127 is a novel small molecule inhibitor of the RNA regulatory factor HuR, which inhibits tumor growth, attenuates glial activation in a lipopolysaccharide-induced neuroinflammation model, and reduces neuropathic pain after nerve injury by inhibiting the neuroinflammatory response.

ω-Conotoxin FVIA is an inhibitor of N-type Ca²⁺ channels (Caᵥ2.2), shown to alleviate mechanical and thermal pain abnormalities in a rat model of caudal nerve injury. This compound has potential utility in the research of potent analgesics with minimal side effects [1].

Monomethyl lithospermate (Lithospermic acid monomethyl ester) has potential antiviral activity, alleviating ischemic stroke injury in vivo in middle cerebral artery occlusion mice by activating PI5K/Akt signaling and protecting oxygen-glucose deprivation/reoxygenation-induced SHSY-3Y cells in vitro. Monomethyl lithospermate could improve the viability of SHSY-5Y cells, inhibit mitochondrial membrane potential (MMOP) collapse, and inhibit cell apoptosis. Monomethyl lithospermate also reduced the level of oxidative stress in the brain tissue of middle artery occlusion (MCAO) rats and improved nerve damage in ischemic stroke (IS) rats.
