AM-36 is a novel arylalkylpiperazine with combined antioxidant and Na(+) channel blocking actions. This compound was discovered as a four-year Amrad-funded program with the Departments of Pharmacology and Chemistry at Monash University. In preclinical studies was shown, that AM-36 might have great promise in the acute treatment of human stroke. But these investigation were discontinued.

Scutellarin is the main bioactive component of Breviscapine prepared from the traditional Chinese herb Erilgeron breviscapus (Vant) Hand-Mazz. Scutellarin demonstrated protective effect on cardiovascular and cerebrovascular ischemia. The potential cytoprotective effects of the drug against cerebrovascular ischemia were evidenced by reducing cerebral infarct sizes, ameliorating neurological deficit and inhibiting neuronal apoptosis. Scutellarin is capable of inhibiting I(Na) in neurons through predominantly affecting the inactivated state of I(Na). Scutellarin may alleviate cognitive impairment in a mouse model of hypoxia by promoting proliferation and neuronal differentiation of neural stem cells. Scutellarin might play an therapeutic role by inhibiting oxidative stress and apoptosis in Alzheimer's disease treatment.

(R)-Ropivacaine (Dextroropivacaine) is a voltage-dependent potassium channel blocker with local anesthetic activity. (S)-Ropivacaine is a medication used for the production of local or regional anesthesia for surgery and for acute pain management. Ropivacaine shows a difference in channel blockade between two enantiomers, and R-Ropivacaine shows greater cardiotoxicity than (S)-Ropivacaine. (R)-Ropivacaine is the impurity in commercial formulations of Ropivacaine.

Bufalin is a traditional oriental medicines, originally isolated from the Chinese toad venom. Bufalin is a cardiotonic steroid that has the potential to induce differentiation and apoptosis of tumor cells. Research on bufalin has so far mainly involved leukemia, prostate cancer, gastric cancer and liver cancer, and has been confined to in vitro studies. The bufadienolides bufalin and cinobufagin have been shown to induce apoptosis in a wide spectrum of cancer cell. Bufalin has being shown to be a potent small-molecule inhibitor of the steroid receptor coactivators SRC-3 and SRC-1. Bufalin is a component of Huachansu, a Chinese medicine that comes from dried toad venom from the skin glands of Bufo bufo gargarizans Cantor or B.melanotictus Schneider, has been used in the treatment of various cancers in China.

WIN 55212-2 is the synthetic cannabimimetic compound. It is a potent aminoalkylindole cannabinoid receptor agonist. WIN 55,212-2 increases expression of anti-oxidant Cu/Zn SOD and is able to prevent inflammation induced by Aβ1-42 in cultured astrocytes. It exerts neuroprotective and anti-inflammatory actions against Aβ damage through both CB₁ and CB₂ receptors. WIN 55212-2 attenuates hyperalgesia and allodynia in a rat model of neuropathic pain. In the clinical trial, it was revealed that WIN 55212-2, applied topically, decreases the intraocular pressure of human glaucoma resistant to conventional therapies within the first 30 min.

Phenthiazamine was developed by Sekizawa et al. as a centrally acting anesthetic for fish. The time required to reduce the positive ganglionic potential in the sympathetic ganglion by phenthiazamine was prolonged in the presence of higher concentrations of Ca2+. The Ca2+-dependent action potential of guinea-pig ureter was reduced by this compound, whereas it did not affect the Na+-dependent action potential.

R-Duloxetine is an enantiomer of the antidepressant S-duloxetine. R-Duloxetine was shown was highly effective against postoperative pain, which could be potential new analgesics. R-Duloxetine could show its effect via the blocking of the neuronal Na⁺ channels.
