TD-004
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.

Biological Activity

VHL |
TD-004 exhibits anti-ALK activities with an IC50 of 0.11 μM, binds VHL with micromolar affinities.
TD-004 (1 μM) degrades NPM-ALK protein with 93% in SU-DHL-1, this degradation effectivity is not correlated with ALK inhibitory activity[1].
TD-004 (0.03-30 µM, 8-16 h) degrades fusion protein EML4-ALK in NCI-H3122 cell lines in time and dose dependent manner[1].
TD-004 (0.2-3 μM, 1-16 h) effectively induces the intracellular fusion ALK degradation by E3 ligase VHL in H3122 cell and proteasome mediated mechanism in SU-DHL-1 cells[1].
TD-004 (3 days) selectively inhibits the cell proliferation of SU-DHL-1, H3122 cancer cells (ALK positive cancer cell lines) with IC50s of 0.058 μM,0.28 μM, but not inhibits A549 cells (IC50 > 10 μM)[1].

-
Cell Line:NCI-H3122 cell
-
Concentration:0.03, 0.3, 3 and 30 μM
-
Incubation Time:8 or 16 h
-
Result:Degraded fusion protein EML4-ALK in dose-dependent manner for 16 h.
Slightly reduced ALK level at 8h treatment at high concentration, which indicated a time-dependent degradation pattern.
-
Cell Line:H3122 cells
-
Concentration:0.3 and 3 μM
-

-
Result:Induced ALK degradation, which was blocked by co-treatment with Epoxomicin (HY-13821) (1 μM).
-
Cell Line:SU-DHL-1 cells
-
Concentration:0.2 μM
-
Incubation Time:16 h
-
