InChIKey: DYEAAIMUSQBHPL-MLENZQCQSA-N
SMILES: CC(C)OC(C=C(C1CCN(CC1)C(CCCC(N[C@@H](C(C)(C)C)C(N2[C@@H](C[C@H](C2)O)C(NCC3=CC=C(C4=C(N=CS4)C)C=C3)=O)=O)=O)=O)C(C)=C5)=C5NC6=NC=C(Cl)C(NC7=C(C=CC=C7)S(C(C)C)(=O)=O)=N6
Biological Activity: TD-004 is a potent ALK PROTAC degrader. TD-004 exhibits anti-ALK inhibitory activity with an IC50 of 0.11 µM and selectively inhibits the proliferation of SU-DHL-1 and H3122 cells (ALK-positive cancer cells) with IC50s of 0.058 µM and 0.28 µM, respectively. TD-004 induces degradation of ALK fusion proteins (NPM-ALK and EML4-ALK) via recruitment of the VHL E3 ligase and the proteasome pathway. TD-004 demonstrates significant tumor growth inhibition with a favorable safety profile in vivo. TD-004 can be used for the research of anaplastic large cell lymphoma and non-small cell lung cancer[1][2].
