SD-436
Based on 1 Customer Validation
SD-436 is a highly selective and efficacious STAT3 PROTAC degrader (DC50: 0.5 μM), with IC50 of 19 nM (STAT3), 270 nM (STAT1), 360 nM (STAT4), >10 μM (STAT5) and >10 μM (STAT6). SD-436 promotes ubiquitination and degradation of STAT3, and induces tumor regression. SD-436 can be used for tumor research, such as leukemia and lymphoma.
(Pink: STAT3 ligand (HY-169361); Blue: Cereblon ligand (HY-43722); Black: linker (HY-147052)).

SD-436 (4 day treatment) inhibits the growth of MOLM-16 leukemia cell line, SU-DHL-1 and SUP-M2 lymphoma cell lines, with IC50 of 0.038 μM (MOLM-16), 0.43 μM (SU-DHL-1) and 0.39 μM (SUP-M2)[1].
SD-436 (0.1 nM-40 μM, 4 or 20 h) selectively reduces the levels of STAT3 protein in human PBMCs, SU-DHL-1 and MOLM-16 cell line (4 h)[1].
SD-436 (0.1 nM-40 μM, 20 h) effectively reduces the levels of the mutated STAT3 protein (STAT3K658R) in a dose-dependent manner in the Pfeiffer cell line, with a DC50 value of 2.5 nM[1].
SD-436 shows excellent stability in mouse, rat, dog, monkey and human plasma, with T1/2 of >120 min[1].
SD-436 has no significant inhibition of the human ether-a-go-go-related gene potassium channels (hERG inhibition: 1.3% for 3μM and 1.1% for 30 μM)[1].

Result:Reduced the levels of STAT3 protein in human PBMCs and SU-DHL-1 cell line, with DC50 of 0.1 nM and 10 nM, respectively.
Achieved near complete degradation at 320 nM with merely a 4 h treatment time in the MOLM-16 cell line.
Reduced the levels of the mutated STAT3 protein in a dose-dependent manner in the Pfeiffer cell line, with a DC50 value of 2.5 nM.
Showed high selectivity for STAT3 over other STAT proteins.
SD-436 (5-25 mg/kg, i.v.) shows antitumor activity in leukemia and lymphoma xenograft models in mice[1].
