Biological Activity

kobe2602 is a small-molecule inhibitor of ras with ki value of 149 μm [1].kobe2602 is a compound screened out by a computer-assisted search of about 160,000 compounds. it dose-dependently inhibited the binding of h-rasg12v to c-raf-1 in nih 3t3 cells with a rough ic50 value of 10 μm. 20 μm of kobe2602 effectively suppressed the phosphorylation of down-stream kinases of raf, including mek and erk. besides that, in nih 3t3 cells transfected with h-rasg12v, kobe2602 inhibited the colony formation with ic50 value of 1.4 μm. kobe2602 also showed effect on other cancer cells carrying activated ras oncogenes, such as panc-1(k-rasg12v), ht1080 (n-rasq61l) and hct116 (h-rasg13d). moreover, in mice bearing sw480 xenografts, administration of kobe2602 resulted in 40-50% inhibition of the tumor growth at dose of 80 mg/kg [1].
