In the human cancer xenograft models deficient in SMARCA4, notably the H838 model, SMD-3236 effectively induces loss of SMARCA2 in tumor tissue while sparing the SMARCA4 protein, thereby inhibiting tumor growth. The compound consists of a target protein ligand (red part) SMI-1074, a PROTAC linker (black part) (trans-4-Ethynylcyclohexyl)methyl methanesulfonate, and an E3 ligase ligand (blue part) SMARCA2 ligand-14, forming the E3LigaseLigand-linker Conjugate 159.
