Description

PROTAC METTL3 degrader 1 is a VHL-based PROTAC METTL3 degrader (DC50: 220 nM in MOLM-13 cells). PROTAC METTL3 degrader 1 inhibits METTL3/14 complex with an IC50 value of 341 nM. PROTAC METTL3 degrader 1 can be used for the research of acute myeloid leukemia and gastric cancer[1]. (Pink: METTL3 ligand (HY-115717); Blue: VHL ligand (HY-120217); Black: linker).

In Vitro

PROTAC METTL3 degrader 1 (KH12) inhibits the methyltransferase activity of the purified METTL3/METTL14 complex with an IC50 of 341 nM[1].
PROTAC METTL3 degrader 1 (KH12) (0.039-5 μM; 0-48 h) induces potent, dose- and time-dependent degradation of METTL3 in MOLM-13 cells, with a DC50 of 220 nM, 84% degradation at 1 μM for 24 h, and over 90% degradation at 1 μM for 24 h[1].
PROTAC METTL3 degrader 1 (KH12) (1 μM; 2.5 h pre-incubation, 6 h treatment) induces METTL3 degradation via the ubiquitin-proteasome system, not the autophagy-lysosomal pathway, in HEK293T cells[1].
PROTAC METTL3 degrader 1 (KH12) (72 h) potently suppresses the proliferation of MOLM-13 acute myeloid leukemia cells with an IC50 of 1.04 μM[1].
PROTAC METTL3 degrader 1 (KH12) (0.1-5 μM; 48 h) reduces c-MYC protein levels in a dose-dependent manner in MOLM-13 cells[1].
PROTAC METTL3 degrader 1 (KH12) (5 μM; 48 h) promotes myeloid differentiation of MOLM-13 acute myeloid leukemia cells, as demonstrated by increased CD11b expression[1].
PROTAC METTL3 degrader 1 (KH12) (1-10 μM; 48 h) induces dose-dependent apoptosis in MOLM-13 acute myeloid leukemia cells, with 78% apoptotic cells[1].
PROTAC METTL3 degrader 1 (KH12) (0.1-10 μM; 24 h) reduces METTL3 protein levels in GES-1 normal gastric cells, AGS gastric cancer cells, and SNU484 gastric cancer cells[1].
PROTAC METTL3 degrader 1 (KH12) (72 h) potently suppresses the proliferation of AGS and SNU484 gastric cancer cells with IC50 values of 1.48 μM and 3 μM respectively, while having minimal effect on GES-1 normal gastric cells[1].
PROTAC METTL3 degrader 1 (KH12) (1 μM; 24 h) reduces METTL3 protein levels in both cytoplasmic and nuclear fractions of AGS and SNU484 gastric cancer cells[1].
PROTAC METTL3 degrader 1 (KH12) (0.0001-100 μM; 5 days) significantly suppresses the growth of gastric cancer patient-derived organoids (GA215T and GA352T), with GA215T organoids showing greater sensitivity to the Target Reagent than to small molecule METTL3 inhibitors[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
