Mécanisme daction

Targets/IC₅₀/Ki	Smoothened (TM3Hh12 cells) 46 nM
In vitro	La cyclopamine inhibe la voie de signalisation Hedgehog avec une CI50 de 46 nM, et bloque l'activité du récepteur Smo humain exprimé dans les cellules CHO-K1 lors d'un test de liaison au [³H]Hh-Ag avec une CI50 de 280 nM. Ce composé inhibe significativement l'activité de la voie Hedgehog de manière dose-dépendante dans les lignées cellulaires tumorales dérivées de l'intestin exprimant l'ARNm de Patched (PTCH), et induit une inhibition de la croissance de ces lignées cellulaires tumorales de 75-95% à la concentration de 3 μM, mais est inefficace contre les cellules tumorales du côlon sans expression de l'ARNm de PTCH, suggérant que les effets de ce traitement chimique sont liés à la voie Hedgehog plutôt que généralement cytotoxiques. En bloquant la signalisation Hedgehog par interaction directe avec Smo, il (10 μM) inhibe la prolifération des lignées cellulaires SMO^high réactives à la cyclopamine L3.6sl et Panc 05.04 de 75 à 80%, et augmente l'apoptose de 2,5 à 3,5 fois, sans affecter la lignée cellulaire BxPC3-SMO^low. Ce traitement diminue significativement l'ARNm de Snail et augmente les transcrits d'E-cadherin dans la lignée cellulaire E3LZ10.7. Indépendamment de l'inhibition de la croissance cellulaire, il inhibe significativement le phénotype invasif des cellules L3.6pl dépendantes de Hedgehog, provoquant une réduction de >500 fois du nombre de cellules transmigrantes, mais pas celui de la lignée cellulaire Panc-1 indépendante de Hedgehog.
Kinase Assay	Essai cellulaire Hedgehog
Kinase Assay	Cet essai mesure le stade final de la voie de signalisation Hh, c'est-à-dire la modulation transcriptionnelle de Gli, en utilisant la luciférase comme lecture (essai Gli-Luc). La cyclopamine est préparée pour l'essai par dilution en série dans du DMSO, puis ajoutée à des plaques d'essai vides. Les cellules TM3Hh12 (cellules TM3 contenant le construit de gène rapporteur répondant à Hh pTA-8xGli-Luc) sont resuspendues dans du F12 Ham's/DMEM (1:1) contenant 5% de FBS et 15 mM de Hepes pH 7.3, ajoutées aux plaques d'essai et incubées avec ce composé pendant environ 30 minutes à 37 °C dans 5% de CO₂. 1 nM de Hh-Ag 1.5 est ensuite ajouté aux plaques d'essai et incubé à 37 °C en présence de 5% de CO₂. Après 48 heures, du réactif Bright-Glo ou MTS est ajouté aux plaques d'essai et la luminescence ou l'absorbance à 492 nm est déterminée. La valeur de la CI50, définie comme le point d'inflexion de la courbe logistique, est déterminée par régression non linéaire de la luminescence de la luciférase pilotée par Gli ou du signal d'absorbance de l'essai MTS versus log10 (concentration) de ce produit chimique à l'aide du logiciel statistique R.
In vivo	L'administration de Cyclopamine à une dose de 50 mg/kg/jour pendant 22 jours éradique les xénogreffes HUCCT1 chez la souris sans effets indésirables apparents. Le traitement avec ce composé à une dose de 1,2 mg pendant 7 jours induit une apoptose significative des cellules tumorales et diminue la masse tumorale de 50 à 60% dans les tumeurs dérivées de Panc 05.04 et L3.6sl, respectivement, mais pas dans les tumeurs BxPC3-SMO^low. [3] L'administration de ce produit chimique seul inhibe profondément les métastases tumorales dans les xénogreffes de E3LZ10.7 et L3.6pl, et abroge complètement les métastases en combinaison avec la gemcitabine.

Questions fréquemment posées

Question 1:
How to reconstitute it for in vivo use in mice?

Réponse :
One paper dissolved this compound in DMSO, and diluted it in saline: Berman DM, et al. Nature, 2003, 425(6960), 846-851. Alternatively, you can try this vehicle: 10% DMSO+30% PEG 300+5% Tween 80+ddH2O for P.O. When preparing the solution, please dissolve it in DMSO clearly first. Then add PEG300 and Tween, after they mixed well, dilute with water.
