Further, the compound dose dependently inhabited BRAFV600E enzyme with an IC50 value of 70.84 nM (Fig. 6c). In order to evaluate if the enzyme inhibitory effects of CB-006-3 is translated into the anticancer efficacy, we carried out the antiproliferative assay with the compound in A375 and G-361 melanoma cells. As observed in Fig. 6d, the compound inhibited the proliferation of both these cells with respective GI50 values of 223.3 and 143.6 nM.
