IHMT-EZH2-426

IHMT-EZH2-426 is an orally active and selective EZH2 degrader. IHMT-EZH2-426 forms a covalent bond with Cys663 of EZH2, inhibits its catalytic activity, and reduces the protein levels of EZH2 as well as the level of H3K27me3. IHMT-EZH2-426 acts as an antiproliferative agent against B-cell lymphoma and triple-negative breast cancer cells, and also exhibits anti-tumor related activity in Pfeiffer and MDA‑MB‑231 xenograft models. IHMT-EZH2-426 can be used in studies related to B-cell lymphoma and triple-negative breast cancer.

IHMT-EZH2-426 (0.03-10 μM; 72 h) inhibits H3K27 trimethylation at a concentration of 0.03 μM and reduces EZH2 protein levels at 1 μM after 72 h of treatment in Karpas-422, Pfeiffer, MDA-MB-231 and MDA-MB-468 cell lines^[1].
IHMT-EZH2-426 (10 μg/mL; 72 h treatment, up to 48 h washout) achieves sustained inhibition of H3K27me3 for at least 48 h after washout in MDA-MB-231 cells, confirming its persistent binding to the target^[1].
IHMT-EZH2-426 (1-50 μM; 4 h compound treatment, 4 h probe incubation) binds to EZH2 in MDA-MB-231 cell lysates, and labels approximately 50% of available target proteins at a concentration of 1 μM^[1].
IHMT-EZH2-426 forms a covalent adduct with purified EZH2 (SET domain) protein, confirming its covalent binding mechanism^[1].

Anti-cancer

IHMT-EZH2-426 (0.1-10 μM; 5 days) potently inhibits the proliferation of EZH2-mutant B-cell lymphoma cell lines (GI₅₀ 0.02-3.85 μM), and exhibits moderate antiproliferative activity against EZH2-wild-type B-cell lymphoma cell lines as well as triple-negative breast cancer (TNBC) cells (GI₅₀ 1.93-7.01 μM)^[1].
IHMT-EZH2-426 (for 14 days) inhibits colony formation of MDA-MB-231 and MDA-MB-468 triple-negative breast cancer (TNBC) cells in a dose-dependent manner^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
