Biological Activity

Description Eletriptan (UK-116044) is a selective 5-HT1B and 5-HT1D receptor agonist with Ki of 0.92 nM and 3.14 nM, respectively.
Targets
5-HT1B [1] 5-HT1D [1]
0.92 nM(Ki) 3.14 nM(Ki)
In vitro
In vitro [3H]Eletriptan has a total number of binding sites (Bmax) of 2478 fmol/mg and 1576 fmol/mg for 5-HT1B and 5-HT1D, respectively. [3H]Eletriptan has a significantly faster association rate (K(on) 0.249/min/nM) than [3H]sumatriptan (K(on) 0.024/min/nM) and a significantly slower off-rate (K(off) 0.027/min compared to 0.037/min for [3H]sumatriptan). [1] Eletriptan induces concentration-dependent contractions of meningeal artery, coronary artery, and saphenous vein. The potency of Eletriptan is higher in meningeal artery than in coronary artery (86-fold) or saphenous vein (66-fold). The predicted contraction by Eletriptan (40 mg and 80 mg) and sumatriptan (100 mg) at free C(max) observed in clinical trials is similar in meningeal artery. [2]
In Vivo
In vivo Eletriptan (<1000 mg/kg, i.v.) produces a dose-dependent reduction of carotid arterial blood flow in the anaesthetised dog. Eletriptan reduces coronary artery diameter with ED50 value of 63 mg/kg in the anaesthetised dog. Eletriptan (<300 mg/kg, i.v.) administered prior to electrical stimulation of the trigeminal ganglion produces a dose-related and complete inhibition of plasma protein extravasation in the dura mater rats. Eletriptan (100 mg/kg, i.v.) produces a complete inhibition of plasma protein extravasation in rat dura mater. [3] Headache response rates are 24% for placebo; 54% for Eletriptan (20 mg);65% for Eletriptan (40 mg);and 77% for Eletriptan (80 mg) at the primary endpoint (2 hours after dosing) in patients with migraine. Headache-free rates at 2 hours are 6% for placebo, 29% for Eletriptan (40 mg) and 37% for Eletriptan (80 mg) at the primary endpoint (2 hours after dosing) in patients with migraine. Eletriptan is well tolerated, and the majority of adverse events are mild or moderate in intensity and transient in patients with migraine. [4] Iontophoretic ejection (50 nA) of Eletriptan suppresses the response in 75% of cells and causes an average suppression of cell firing of 42% in cats. [5]

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
