Fig. 3From: Emerging strategies to target RAS signaling in human cancer therapyPreclinical and clinical drugs targeting RAS-mutant tumors. (a) Targeting upstream molecules of RAS. Promising targets include PDEδ, SHP2, and STK19. (b) Targeting RAS directly, especially G12C covalent binders. (c) Targeting downstream RAF–MEK–ERK signaling. (d) Targeting downstream PI3K–AKT–mTOR signaling. (e) RNA interference of mutant RAS mRNA. Molecules that underwent clinical trials are indicated in green, those that are now under preclinical evaluation are indicated in lack. Napa, nanoparticleBack to article page
