Étape 1 : Saisir les informations ci-dessous (Recommandé : Un animal supplémentaire pour tenir compte des pertes pendant l'expérience)
Étape 2 : Saisir la formulation in vivo (Ceci est seulement le calculateur, pas la formulation. Veuillez nous contacter d'abord s'il n'y a pas de formulation in vivo dans la section Solubilité.)
Résultats du calcul :
Concentration de travail : mg/ml;
Méthode de préparation du liquide maître DMSO : mg médicament prédissous dans μL DMSO ( Concentration du liquide maître mg/mL, Veuillez nous contacter d'abord si la concentration dépasse la solubilité du DMSO du lot de médicament. )
Méthode de préparation de la formulation in vivo : Prendre μL DMSO liquide maître, puis ajouterμL PEG300, mélanger et clarifier, puis ajouterμL Tween 80, mélanger et clarifier, puis ajouter μL ddH2O, mélanger et clarifier.
Méthode de préparation de la formulation in vivo : Prendre μL DMSO liquide maître, puis ajouter μL Huile de maïs, mélanger et clarifier.
Note : 1. Veuillez vous assurer que le liquide est clair avant d'ajouter le solvant suivant.
2. Assurez-vous d'ajouter le(s) solvant(s) dans l'ordre. Vous devez vous assurer que la solution obtenue, lors de l'ajout précédent, est une solution claire avant de procéder à l'ajout du solvant suivant. Des méthodes physiques telles que le vortex, les ultrasons ou le bain-marie chaud peuvent être utilisées pour faciliter la dissolution.

Aprepitant antagonizes the effects of substance P by binding to NK-1 receptors primarily in the CNS, but also in the periphery. This compound, at concentrations of 0.1 nM displaces 50% of substance P from hNK1 receptors transfected in CHO or COS cells. In radioligand binding assays, it is 3000-fold selective for the human cloned NK1 receptor versus the human cloned NK3 receptor and >50,000-fold selective over the human cloned NK2 receptor. In a range of assays at other human cloned G–protein coupled receptors, this chemical retains >50,000-fold selectivity for the human cloned NK1 receptor. It is inactive in human monoamine oxidase A and B assays and at human serotonin 5–HT1A, 5–HT2A, 5–HT2c, 5–HT3, 5–HT5, 5–HT6, and 5–HT7 receptors (IC50>3 μM). In the PANLABS panel of radioligand binding screens using native animal tissues, this compound inhibits [3H]substance P binding to native NK1 receptors in rat submaxillary gland; there are no significant interactions of it with any other native animal G–protein coupled receptors or ion channels examined in the PANLABS screen. It is inactive in monoamine uptake site (NE, 5–HT, DA) counterscreens using human and animal tissues (IC50> 3 μM) |
| In vivo |
Aprepitant crosses the blood–brain barrier and occupied NK-1 receptors in the brain. This compound has been shown to inhibit both acute and delayed emesis induced by cytotoxic chemotherapeutic such as cisplatin by blocking substance P. It (3 mg/kg i.v. or p.o.) inhibits the emetic response to cisplatin (10 mg/kg i.v.). The anti-emetic protection afforded by this chemical (0.1 mg/kg i.v.) is enhanced by combined treatment with either dexamethasone (20 mg/kg i.v.) or the 5–HT3 receptor antagonist ondansetron (0.1 mg/kg i.v.). In a model of acute and delayed emesis, ferrets are dosed with cisplatin (5 mg/kg i.p.) and the retching and vomiting response recorded for 72 h. Pretreatment with it (4–16 mg/kg p.o.) dose-dependently inhibits the emetic response to cisplatin. Once daily treatment with this compound (2 and 4 mg/kg p.o.) completely prevents retching and vomiting in all ferrets tested. Further when daily dosing began at 24 h after cisplatin injection, when the acute phase of emesis had already become established, it (4 mg/kg p.o. at 24 and 48 h after cisplatin) prevents retching and vomiting in three out of four ferrets. This chemical also plays a key part in transmission of pain impulses from the peripheral receptors to the CNS and is involved in various behavioural, neurochemical and cardiovascular responses to stress. |
