4、BRAF and CRAF respectively. LY3009120 exhibits anti-proliferative effects oncell lines harboring BRAFV600E, KRASG13 and KRASG12 mutations. LY3009120 (1 M) inhibits thephosphorylation of both MEK1/2 and ERK1/2 in cell lines with high basal levels of pMEK1/2 and pERK1/2(RKO and HCT 116) 1. LY3009120 s

5、hows inhibitory effect on tumor cells such as BxPC-3, NCI-H2405 andOV-90 cell lines. LY3009120 (0.01 M) demonstrates potent and dose-dependent inhibition of phospho-MEKand ERK in all three cell lines. LY3009120 demonstrates a concentration-dependent cell growth inhibitionwith IC50 values of 0.04, 0.

6、087, and 0.007 M against H2405, BxPC-3, and OV-90 cells, respectively 2.LY3009120 inhibits BRAFWT, CRAFWT, BRAFV600E, and BRAFV600E+G468A with the IC50 values of 9.1,15, 5.8, and 17 nM, respectively. LY3009120 induces BRAF-CRAF dimerization but inhibits thephosphorylation of downstream MEK and ERK.

7、LY3009120 also inhibits various forms of RAF dimersincluding BRAF or CRAF homodimers 3. LY3009120 gives only very minor activation at very low doses,with near complete inhibition of phospho-ERK at concentrations above 100 nM 4.體內(nèi)研究 LY3009120 (20 mg/kg bid) displays significant activity in in vivo BR

8、AFmut and KRASmut CRC xenograftmodels. In Colo 205 xenografts (BRAFmut), LY3009120 results in statistically significant tumor regression,while treatment of HCT 116 xenografts (KRASmut) results in statistically significant inhibition of tumor growth.LY3009120 treatment reduces pMEK1/2 in all HT-29 xe

9、nografts and reduces pERK1/2 in the majority of HT-29 xenografts 1. LY3009120 (15 or 30 mg/kg) achieves almost complete tumor growth regression, andinhibits downstream phospho-MEK and ERK by approximately 70% and 60%, respectively, in the H2405model 2.PROTOCOLKinase Assay 3 In the BRAF WT enzymatic
