"CAPSAICIN"
to a specific field?
AMG-517, a potent and selective vanilloid receptor (VR1) antagonist, was in clinical trials with Amgen for the treatment of pain. AMG 517 inhibits CAP- (500 nM), acid- (pH 5.0), or heat-(45 °C) induced 45Ca2+ influx into human TRPV1-expressing CHO Cells with IC50 of 0.76 nM, 0.62 nM and 1.3 nM. AMG-517 blocks capsaicin-, proton-, and heat-induced inward currents in TRPV1-expressing cells similarly. AMG-517 inhibits native TRPV1 activation by capsaicin in rat dorsal root ganglion neurons with an IC50 value of 0.68 nM. Oral administration of AMG-517 produces a dose-dependent increase in plasma concentrations, it also produces a dose-dependent decrease in the number of flinches induced by capsaicin treatment. The minimally effective dose (MED), based on a statistically significant difference in number of flinches from the vehicle versus capsaicin-administered group, is 0.3 mg/kg for AMG 517. The corresponding plasma concentrations are 90 to 100 ng/mL for AMG-517. AMG-517 (3 mg/kg) exhibits significant reductions in capsaicin-induced flinch up to 24 h after dosing. AMG 517 blocks thermal hyperalgesia in CFA model of pain. Unfortunately, clinical studies of AMG-517 were discontinued due to the hyperthermia observed after exposure to single and multiple doses.

CHEMICAL (ACHIRAL)
Targets:
Vanillin (4-hydroxy-3-methoxybenzaldehyde), a pleasant smelling organic aromatic compound, is widely used as a flavoring additive in food, beverage, cosmetic and drug industries. It is reported to cross the blood brain barrier and also displayed antioxidant and neuroprotective activities. Vanillin is a natural substance widely found in many plant species and often used in beverages, foods, cosmetics, and pharmaceutical products. Antioxidant and anticancer potential have been described for this compound. Vanillin has been classified as
a bioantimutagen and is able to inhibit mutagenesis induced
by chemical and physical mutagens in various cell systems. Vanillin, a selective agonist of TRPV1, has been shown to attenuate i.c.v. STZ and AlCl3+d-galactose induced experimental Alzheime's disease (AD).

Conditions:
Dihydrocapsaicin is a capsaicinoid and analog and congener of capsaicin in chili peppers. Like capsaicin, it contributes to the spicy taste of chili peppers, although it is less potent than capsacian. Dihydrocapsaicin has been shown to induce hypothermia in rats, a property which may help protect victims of stroke and cardiac arrest.
