Jervine

Synonyms: 11-Ketocyclopamine

Jervine (11-Ketocyclopamine) is a Hedgehog signaling (IC50=500-700 nM) inhibitor that inhibits the sonic hedgehog (shh) pathway by interacting with smoothened.

Biological Activity

Description Jervine (11-Ketocyclopamine) is a Hedgehog signaling (IC50=500-700 nM) inhibitor that inhibits the sonic hedgehog (shh) pathway by interacting with smoothened.
Targets
Hedgehog [1] Shh [1]
In vitro
In vitro Compared to controls, chondrocyte cultures exposed to 25 μg/ml jervine shows an apparent reduction in cell number but no differences in cellular morphology or relative intensity of alcian blue staining[2].
Cell Research Cell lines C3H/10T 1/2 CL8 cells
Concentrations 5, 10, or 25 μg/ml
Incubation Time 48 h
Method

Cells are grown in Eagle's basal medium supplemented with 10% fetal bovine serum and 0.25 mg/ml gentamicin sulfate. Cells are seeded onto 35-mm tissue culture plates at a density of 1×104 celldplate. The plated cells are incubated for 24 hours prior to treatment in a humidified incubator at 37 "C in an atmosphere of 5% CO2 in air. Drugs are then added: jervine to a final concentration of 5, 10, or 25 μg/ml; retinoic acid at 0.03, 0.30, or 3.0 pg/ml. After a final 48 hours of incubation, media are removed, the cultures are rinsed three times with phosphate-buffered saline (PBS) pH 7.4, and the cells are harvested into 0.5 ml of 0.1% (w/v) trypsin which contained 0.1% EDTA (w/v) in PBS. Each sample is mixed with 9.5 ml Isoton Ⅱ, and cell numbers are determined by using a Coulter Counter.
In Vivo
In vivo Embryos exposed to jervine develop craniofacial abnormalities related to those found in Shh mutant embryos. The lower jaw of these embryos is severely reduced in size, often leading to loss of the incisors. Treatment of pregnant mice with the hedgehog inhibitor jervine induces jaw defects in the embryos similar to those found in Prx1−/−Prx2−/− embryos. The distal part of the jaw is reduced in size, and both incisors are absent[1].

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.
