Zolmitriptan (311C90) selectively binds to and activates serotonin (5-HT) 1B receptors expressed in intracranial arteries and 5-HT 1D receptors located on peripheral trigeminal sensory nerve terminals in the meninges and central terminals in brainstem sensory nuclei. Zolmitriptan is a member of the triptan class of agents with anti-migraine properties. Receptor binding results in constriction of cranial vessels, reduction of vessel pulsation and inhibition of nociceptive transmission, thereby providing relief of migraine headaches. Zolmitriptan may also relieve migraine headaches by inhibition of pro-inflammatory neuropeptide release.

Dihydrocapsaicin (CCRIS1589) is isolated from Capsicum fruit. Capsaicin is the primary active component of the heat and pain-eliciting lipid soluble fraction of the Capsicum pepper. Like capsaicin, dihydrocapsaicin is an irritant. Capsaicin is found in natural hot pepper extracts along with a number of impurities, including dihydrocapsaicin and several lesser impurities. Separation by HPLC is required in order to obtain pure dihydrocapsaicin. Dihydrocapsaicin represents about 10% of the compound present in commercial preparations purporting to be pure capsaicin, but it has about the same pungency as capsaicin. VR1 (vanilloid receptor 1) is a heat activated calcium ion channel which functions as a part of the normal nociceptive pain pathway. Capsaicin elicits a sensation of burning pain by activation of VR1 on small, non-myelinated polymodal C-type nociceptive nerve fibers. The potency of dihydrocapsaicin at VR1 appears equivalent to capsaicin. Antioxidant. Reduces oxidation of serum lipids. Mutagenic. Dihydrocapsaicin is an activator of VR1.

1. Bullatine A, a diterpenoid alkaloid of the genus Aconitum, possesses anti-rheumatic, anti-inflammatory and anti-nociceptive effects, may be used for the treatment of neurodegenerative diseases such as arthritis.

1. Vitexin has antinociceptive and antispasmodic activities. 2. Vitexin exhibits a prominent first-pass effect. 3. Vitexin has antioxidant, antimyeloperoxidase, and α-glucosidase inhibitory activities. 4. Vitexin can either inhibit or induce activities of

Ziconotide Acetate (107452-89-1 free base) (Prialt) is an analgesic agent and has been used to treat neuropathic and non-neuropathic pain. Ziconotide Acetate (107452-89-1 free base) acts by binding to N-type calcium channels situated on the terminal part of primary afferent neurons of the nociceptive pathway therefore reducing synaptic transmission with potent antinociceptive effects.

Alosetron hydrochloride (GR 68755) is the hydrochloride salt form of alosetron, a potent and selective 5-HT3 receptor antagonist. Alosetron blocks the actions of serotonin at 5-HT3 sites in the peripheral nervous system, particularly on enteric and nociceptive sensory neurons, thereby affecting the regulation of visceral pain, decreasing gastrointestinal contraction and motility, and decreasing gastrointestinal secretions.
