Biological Activity

Description Tovorafenib (MLN2480, BIIB-024, TAK580, AMG-2112819, BSK1369, DAY-101) is an oral, selective pan-Raf kinase inhibitor in chinical trials.
Raf [1]
In vitro

MLN2480 inhibits MAPK pathway signaling in BRAF mutant and some RAS mutant preclinical cancer models at concentrations that are tolerated in vivo[1]. It is found to activate phosphorylated MEK at very low concentrations, but inhibits this same activity at higher concentrations. The inhibitory effects of MLN-2480 are found to vary across models and genetic contexts[2]. In vitro analysis of this drug combination of MLN2480 and TAK-733(an investigational allosteric MEK kinase inhibitor) in cell proliferation assays demonstrates synergistic activity .In addition, western blot analysis demonstrates the effect of MLN2480 in reversing feedback activation of MEK in response to TAK-733, leading to more concerted MAPK pathway inhibition.MLN-2480 only modestly inhibits PRAK[1][2].

In vivo In vivo, MLN2480 shows antitumor activity in melanoma, colon, lung, and pancreatic cancer xenograft models[3].MLN-2480 (37.5 mg/kg) is well tolerated in a tumor xenograft model. The combination of MLN-2480 (12.5 mg) and TAK-733 (1 mg/kg) is effective in an SK-MEL-30 xenograft model, but monotherapy with either compound produces negligible effects[2].

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.
