SD-91
Based on 1 Customer Validation
SD-91 (STAT3 degrader-2), a product of the hydrolysis of SD-36 (HY-129602), is a selective PROTAC-based STAT3 degrader with a Ki of 5.5 nM. SD-91 displays >300-fold selectivity over other STAT family protein members. SD-91 potently induces degradation of STAT3 protein in cells. SD-91 has anticancer effects, such as myeloid leukemia, lymphoma (Pink: ligand for target protein (HY-150895); Black: linker; Blue: E3 ligase ligand; E3 ligase ligand+linker: HY-176506).
(Pink: STAT3 ligand (HY-150895); Blue: E3 ligase ligand; Black: linker).

SD-91 (Compound 92) (0.2 μM, 1 μM, 30 nM, 100 nM, 300 nM; 3 h) decreased the level of total STAT3 protein in acute leukemia Molm-16 cells[1].
In the BLI assays, SD-91 binds to STAT3 with a Kd value of 28 nM, while it displays a very weak affinity (Kd >10 μM) to all other STAT proteins (STAT1, STAT2, STAT4, STAT5A, STAT5B, and STAT6)[2].
In the MOLM-16 acute leukemia, SU-DHL-1, and SUP-M2 lymphoma cell lines, SD-91 has IC50 values of 0.17, 2.6, and 0.46 μM, respectively[2].
SD-91 (1-10 μM; 4 h) effectively reduce the levels of STAT3 protein in a dose-dependent manner, with DC50 values of 0.38 μM, 0.061μM, and 2.5 μM for MOLM-16, SU-DHL-1, and SUP-M2 cells, respectively[2].
