Fig. 4. PAK inhibitors and sotorasib synergistically kill cancer cells.

Fig. 4

a, c Results of the MTT assay revealed that the combination of the PAK inhibitor FRAX597 and sotorasib exerted stronger cytotoxic effects than did sotorasib alone in cancer cells with KRASG12C mutations. b, d Combination treatment of FRAX597 and sotorasib reduced the viability of sotorasib-resistant cells. eh FRAX486 also showed synergy with sotorasib treatment in treatment-naive cells and sotorasib-resistant cells. #CI < 1 at the indicated dose (n = 6 for all experiments).
