rizatriptan

Rizatriptan is an agonist of the serotonin-1b and serotonin-1d receptor.

Rizatriptan benzoate (MK-462 Benzoate) selectively binds to and activates serotonin (5-HT) 1B receptors and 5-HT 1D receptors providing relief of migraine headaches.

Rizatriptan sulfate is a selective serotonin 5-HTID receptor agonist derived from tryptamine.

Rizatriptan-d6 is intended for use as an internal standard for the quantification of rizatriptan by GC- or LC-MS. Rizatriptan is an agonist of the serotonin receptor subtypes 5-HT1B and 5-HT1D. It is selective for 5-HT1B and 5-HT1D receptors over 5-HT1A receptors. Rizatriptan induces vasoconstriction in isolated human middle meningeal arteries. In vivo, rizatriptan reduces head grooming, the number of oculotemporal strokes, eye blinking, and one-eye closures in a Cacna1a mutant transgenic mouse model of migraine. Formulations containing rizatriptan have been used in the treatment of migraine.

Rizatriptan N-oxide is a potential impurity found in commercial preparations of rizatriptan.1It is a degradation product formed under oxidative conditions.

Cemadotin free base(LU103793 free base) is a novel anti-limiting peptide , an analog of Dolastatin 15, a naturally occurring cytotoxic peptide that blocks mitosis and inhibits microtubules (tubulin) with a Ki of 1 μM. Cemadotin is used in research against cancer.

CGS 12066A is a drug which acts as a potent and selective agonist for the 5-HT1B receptor with lower affinity for the three 5-HT₂ receptor subtypes. It is used for studying the role of the 5-HT1B receptor in various processes including perception of pain and the sleep-wake cycle.

Cemadotin hydrochloride is the salt from of Cemadotin (free base), also known as, LU103793, a mitosis inhibitor potentially for the treatment of solid tumours. Cemadotin is also a synthetic derivative of Dolastatin 15, an antiproliferative compound which was isolated from the mollusk Dolabella auricularia. Like Dolastatin 15, LU103793 is highly cytotoxic in vitro (IC50 = 0.1 nM). LU103793 inhibits microtubule polymerization in a concentration-dependent manner (IC50 = 7 microM). Treatment with this compound also induced depolymerization of preassembled microtubules. Cell cycle analysis of tumor cell lines treated with LU103793 indicated a block in the G2-M phase.
