SD-2301
Based on 1 Customer Validation
SD-2301 is a selective STAT3 PROTAC degrader with a DC50 of 4 nM. By bridging the target protein STAT3 and VHL-1 E3 ubiquitin ligase, SD-2301 induces efficient degradation of STAT3 via the ubiquitin-proteasome system, thereby exerting potent anti-tumor and immunomodulatory effects. SD-2301 can be used in research related to lymphoma, melanoma, colon cancer and other tumors.

In Vitro
SD-2301 (0.32-200 nM; 14 h) potently and selectively degrades STAT3, but not other members of the STAT family, in human peripheral blood mononuclear cells (PBMCs), with a DC50 of 8 nM[2].
SD-2301 (0.2-5 μM; 15 h) potently and selectively degrades STAT3 in SU-DHL-1 cells, with no such effect on other members of the STAT family, and its DC50 is 10 nM; meanwhile, this compound upregulates STAT4 levels, and exerts minimal effects on other STAT proteins even at high concentrations[2].
SD-2301 (1 μM; 8 h) is a selective STAT3 degrader in PBMCs, and only reduces the expression levels of 4 off-target proteins by more than 50% at a high concentration of 1 μM[2].
SD-2301 (50 nM; 6 h) fails to degrade STAT3 in SU-DHL-1 cells pretreated with SI-109 (HY-129603), VHL-1 ligand (HY-112078), MLN-4924 (HY-70062) or PR-171 (HY-10455), demonstrating that its degradation mechanism depends on target binding, neddylation and the proteasome pathway[2].
SD-2301 (50 nM; 24 h) potently degrades STAT3 in mouse dendritic cells, and its efficacy is 4 to 5 times higher than that of SD-36[1].

Cell Line:Murine bone marrow-derived dendritic cells (BMDCs)
-
Concentration:50 nM
-
Incubation Time:24 h
-
Result:Successfully and potently induced the degradation of STAT3 protein in murine DCs, exhibiting a degradation potency 4 to 5 times higher than that of SD-36.
-
Cell Line:SU-DHL-1 cells
-
Concentration:50 nM (after pre-treatment with 40 μM SI-109, 20 μM VHL ligand, 0.5 μM MLN-4924, or 0.2 μM PR-171)
-
Incubation Time:6 h
-
Result:The STAT3 degradation induced by SD-2301 was blocked by high-affinity STAT3 ligand, VHL-1 ligand, neddylation inhibitor (MLN-4924), and proteasome inhibitor (PR-171), proving that the degradation relies on target engagement and the proteasome system.

SD-2301 (5 mg/kg; i.p. or i.v.; once every 3 days) potently inhibits tumor growth in the MC38 syngeneic mouse model of colon cancer, exerts profound synergistic inhibition in combination with anti-PD-L1, and increases the proportion of neoantigen-specific CD8+ T cells within tumors[1].
SD-2301 (5 mg/kg; i.v.; once every 3 days) loses its anti-tumor efficacy in B16F10 tumor-bearing Stat3-/- mice, but remains effective in Stat3+/+ mice, demonstrating that its anti-tumor effect is dependent on the target STAT3[1].
SD-2301 (5 mg/kg; i.v.; once every 3 days) loses its antitumor efficacy in cDC1-deficient Batf3-/- tumor-bearing (MC38) mice, demonstrating that its efficacy depends on cDC1 cells[1].
SD-2301 (5 mg/kg; i.v.; once every 3 days) exerts a synergistic tumor growth inhibitory effect in combination with anti-PD-L1 (HY-108730A) in the B16F10 syngeneic mouse melanoma model[1].
