PROTAC SOS1 degrader-6
PROTAC SOS1 degrader-6 is a selective SOS1 PROTAC degrader with a DC50 of 43-130 nM. PROTAC SOS1 degrader-6 induces ubiquitination and degradation of SOS1 via the ubiquitin-proteasome system by recruiting the E3 ligase VHL. PROTAC SOS1 degrader-6 reduces the levels of phosphorylated MEK and ERK. PROTAC SOS1 degrader-6 exerts antiproliferative effects in KRAS-driven cancer cells. PROTAC SOS1 degrader-6 can be used in research related to KRASG12C-mutant cancers and chronic myeloid leukemia.
(Pink: SOS1 ligand (HY-169371); Blue: VHL ligand (HY-125845); Black: linker (HY-W016456)).

PROTAC SOS1 degrader-6 (Compound 23) (0.003-10 μM; 24 h) potently induces dose-dependent degradation of SOS1 in K562 (DC50=130 nM), PANC-1 (DC50=43 nM), MIA PaCa-2 (DC50=61 nM) and NCI-H358 (DC50=50 nM) cell lines after 24 h of treatment[1].
PROTAC SOS1 degrader-6 (1 μM; 0.167-24 h) induces rapid and sustained SOS1 degradation in K562, PANC-1, MIA PaCa-2 and NCI-H358 cell lines at a treatment concentration of 1 μM, with the degradation effect peaking within 4 h and showing no rebound within 96 h[1].
PROTAC SOS1 degrader-6 is a highly selective SOS1 degrader in the MIA PaCa-2 cell line, which exerts no significant effect on the abundance of other cellular proteins including SOS2[1].
PROTAC SOS1 degrader-6 (0-3 μM) downregulates the levels of pMEK and pERK in K562 cell lines via degrading SOS1, thereby inhibiting signal transduction of the RAS-MAPK pathway[1].
PROTAC SOS1 degrader-6 (3-10 days) exhibits significant antiproliferative activity in K562, MIA PaCa-2 (IC50 = 98 nM) and NCI-H358 cell lines[1].
PROTAC SOS1 degrader-6 (1-10 μM) sensitizes KRASG12C-mutant NCI-H358, MIA PaCa-2 and SW837 cell lines to AMG510 (HY-114277), induces a synergistic antiproliferative effect, enhances inhibition of the RAS-MAPK pathway, and increases the level of cell apoptosis[1].

PROTAC SOS1 degrader-6 (i.p.; 30 mg/kg; once daily; for 28 days) induces mild growth inhibition (TGI 11.4%) in NCI-H358 xenograft tumors. When combined with AMG510 (p.o.; 10 mg/kg; once daily; for 28 days), it produces a synergistic effect with a tumor growth inhibition rate of 78.8%, and no toxicity is detected[1].
