SD-965
SD-965 is a selective STAT3 PROTAC degrader with a DC50 of 0.14 μM. SD-965 promotes the ubiquitination and degradation of STAT3. SD-965 induces rapid, complete and persistent depletion of STAT3 protein. SD-965 induces tumor regression in mouse xenograft models of leukemia and lymphoma.

STAT3 0.14 μM (DC50) |
SD-965 (up to 5 μM; 24 h) potently degrades STAT3 in the STAT3 HiBiT assay with a DC50 of 0.14 μM and 85% maximal degradation after 24 h incubation[1].
SD-965 potently inhibits the growth of MOLM-16 leukemia cells (IC50 = 1.3 nM) and SU-DHL-1 lymphoma cells (IC50 = 260 nM)[1].
SD-965 (3.2-2000 nM; 14 h) selectively degrades STAT3 with >90% maximal degradation in human PBMCs after 14 h incubation, with no significant effect on other STAT family proteins up to 2 μM[1].
SD-965 exhibits excellent microsomal and plasma stability in mouse, rat, dog, monkey, and human, with a half-life of >120 min in all tested matrices[1].

Cell Line:SU-DHL-1 human anaplastic large cell lymphoma cells
-
Concentration:3.2-2000 nM
-
Incubation Time:14 h
-
Result:Degraded STAT3 with a DC50 of 80 nM and a Dₘₐₓ of >90%.
Showed no obvious effect on STAT1 or STAT6, modestly reduced STAT2 and STAT5 at 2 μM, and increased STAT4 levels in a dose-dependent manner.

Animal Model:SU-DHL-1 lymphoma xenograft mouse model[1]
-
Dosage:25-50 mg/kg
-
Administration:i.v.; once weekly; for 3-4 consecutive weeks
-
Result:Induced a maximum tumor regression by 58% at 25 mg/kg.
Reduced the tumor volume by 52% on day 5 after the first dose and by 96% on day 16, with 60% of mice without palpable tumors (50 mg/kg).
