Cell lines | Human melanoma A375 (BRAFV600E) cells |
Preparation method | The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 ℃ for several months. |
Reacting condition | 3 ~ 900 nM |
Applications | In human melanoma A375 (BRAFV600E) cells, LGX818 suppressed phospho-ERK (EC50 = 3 nM), thus potently inhibiting cell proliferation (EC50 = 4 nM). Meanwhile, LGX818 did not show any significant inhibition against a panel of 100 kinases (IC50 >900 nM) as well as proliferation of >400 cell lines expressing wild-type BRAF. In addition, biochemical assays showed that the dissociation half-life of LGX818 was >24 hrs. Thus, the inhibition effect of LGX818 remained following drug wash-out. |
Animal models | BRAF mutant or wild-type human tumor xenograft models |
Dosage form | 1 ~ 300 mg/kg; p.o. |
Applications | At an oral dose as low as 6 mg/kg, LGX818 potently (75%) and continuously (>24 hrs) decreased phospho-MEK in human melanoma xenograft models (BRAFV600E). In nude mice and rats bearing multiple BRAF mutant human tumors, LGX818 induced tumor regression at the dose as low as 1 mg/kg. Moreover, for BRAF wild-type tumors, LGX818 did not show any activity at the dose up to 300 mg/kg (b.i.d.), with good tolerability and linear increase in exposure. |
Other notes | Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
| 产品描述 | LGX818 is a potent and selective inhibitor of RAF kinase with EC50 value of 3nM in A375 cells [1]. The V600E mutation of B-Raf in the kinase domain results in constitutive activation of B-Raf and promotes cancer development. LGX818 is a RAF kinase inhibitor targeting V600E mutant B-Raf. It has little effect against wild-type BRAF. LGX818 has selective anti-proliferative and apoptotic activity ion in cells expressing BRAFV600E. It shows no significant activity against a panel of 100 kinases and no suppression of cell growth with more than 400 cell lines expressing BRAFV600E. In the A375 human melanoma cell line, LGX818 inhibits the phospho-ERK with EC50 value of 3nM and causes subsequent cell proliferation inhibition with EC50 value of 4nM. In human melanoma xenograft models, oral administration of LGX818 shows strong decrease in phospho-MEK and induces tumor regression [1, 2]. References: |
