PROTAC HPK1 Degrader-5
Based on 1 Customer Validation
PROTAC HPK1 Degrader-5 is an orally effective and selective HPK1 PROTAC degrader with a DC50 of 5.0 nM. PROTAC HPK1 Degrader-5 recruits the CRBN E3 ligase to specifically induce the degradation of HPK1 via the ubiquitin-proteasome system, which in turn significantly inhibits SLP76 phosphorylation and enhances the activation of the ERK pathway, thereby stimulating the release of IL-2 and IFN-γ. PROTAC HPK1 Degrader-5 can be used in studies related to tumor immunity (e.g., colorectal cancer).
(Pink: HPK1 ligand (HY-175549); Blue: Cereblon ligand (HY-W023573); Black: linker).

In Vitro
PROTAC HPK1 Degrader-5 (500 nM; 24 h) selectively degrades HPK1 in Jurkat cells, while significantly downregulating the novel CRBN substrates IKZF1 and ZFP91, and additionally downregulating AAK1[1].
PROTAC HPK1 Degrader-5 inhibits HPK1 kinase activity in a cell-free biochemical assay, with an IC50 of 125.7 nM[1].
PROTAC HPK1 Degrader-5 (1.5 nM-10 μM) exhibits no cytotoxicity against human peripheral blood mononuclear cells (PBMCs)[1].

Animal Model:C57BL/6 (female, 6 weeks old, subcutaneous injection of 5×105 MC38 cells)[1]
-
Dosage:0.25 mg/kg, 0.5 mg/kg; 1.5 mg/kg; 3.0 mg/kg; 1.5 mg/kg (combination with anti-PD-1 mAb); 3.0 mg/kg (combination with anti-PD-1 mAb)
-
Administration:p.o.; every other day; 14 days
-
Result:Reduced tumor volume compared to the control group.
Showed greater tumor volume reduction at 3.0 mg/kg dose than at 0.25 mg/kg dose.
Achieved a tumor growth inhibition (TGI) value of 42.45% at 1.5 mg/kg monotherapy.
Achieved a TGI of 32.54% at 3.0 mg/kg monotherapy.
Achieved a TGI of 75.83% at 1.5 mg/kg in combination with anti-PD-1 mAb.
Achieved a TGI of 61.56% at 3.0 mg/kg in combination with anti-PD-1 mAb.
Significantly increased CD8+ T cell infiltration into tumor tissue at 1.5 mg/kg and 3.0 mg/kg monotherapy, with 1.5 mg/kg inducing higher infiltration than anti-PD-1 mAb alone.
Further enhanced CD8+ T cell infiltration in combination treatments.
Induced weakened nucleus-to-cytoplasm ratio, nuclear shrinkage, and extensive tumor cell death in all treatment groups.
Caused no significant lesions in major organs (heart, liver, spleen, lung, kidney), no significant body weight loss, and no mortality during treatment.
