E0199 is an innovative and potent KV7/NaV dual-target modulator that activates KV7 potassium channels, including KV7.2/7.3 (EC50 = 12.78 nM), KV7.2 (EC50 = 0.50 μM), and KV7.5 (EC50 = 27.14 nM), while inhibiting NaV1.7 (IC50 = 0.52 μM), NaV1.8 (IC50 = 0.24 μM), and NaV1.9 (IC50 = 0.16 μM) sodium channels. In a mouse model of chronic constriction injury (CCI) to the sciatic nerve, E0199 demonstrated potent analgesic effects without significant impact on cardiac and skeletal muscle ion channels. E0199 is applicable in studies related to neuropathic pain (NP).

QO-58 is a novel Kv7 activator (opener) that activates neuronal Kv7/KCNQ/M channels, dose-dependently activating Kv7 currents, enhancing native neuronal M currents, and causing a decrease in evoked action potentials. It has anti-nociceptive effects on inflammatory pain and can be used for neuronal excitability disorders.

AUY-954 is an effective selective S1P(1) modulator. It can significantly reduce the local expression of EAN rat sciatic nerve T cells, B cells, macrophage infiltration, inflammatory demyelination, interleukin-17 and matrix metalloproteinase-9.

C22 dihydro 1-Deoxyceramide (m18:0/22:0) is a very long-chain atypical ceramide containing a 1-deoxysphinganine backbone. 1-Deoxysphingolipids are formed when serine palmitoyltransferase condenses palmitoyl-CoA with alanine instead of serine during sphingolipid synthesis.1,2 C22 dihydro 1-Deoxyceramide (m18:0/22:0) has been found in mouse embryonic fibroblasts (MEFs) following application of 1-deoxysphinganine alkyne or 1-deoxysphinganine-d3.3 It has also been found as the most prevalent dihydro deoxyceramide species in mouse brain, spinal cord, and sciatic nerve at one, three, and six months of age.4 |1.

(S)-4CPG ((S)-4-Carboxyphenylglycine) is a competitive mGlu1 receptor antagonist that attenuates nociceptive hypersensitivity and nociceptive abnormalities associated with sciatic nerve constriction injuries in rats, and may be used in the study of neurological disorders.

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.

1,2-Dilaurin is a diacylglycerol compound with lauric acid at the sn-1 and sn-2 positions. It is utilized as an internal standard for quantifying diacylglycerols in desheathed rat sciatic nerves. Monomolecular films containing 1,2-dilauroyl-rac-glycerol serve as substrates to assess surface pressure and the effects of procolipase and colipase on porcine pancreatic lipase activity.
