MS8847

Customer Review

Based on 1 Customer Validation

MS8847 is a PROTAC degrader and antiproliferative agent targeting EZH2 (DC₅₀=34.4 nM in EOL-1 MLL-rAML cells). MS8847 recruits the E3 ligase von Hippel-Lindau (VHL) to mediate the degradation of EZH2 via the ubiquitin-proteasome system. MS8847 induces antiproliferative effects in MLL-rearranged acute myeloid leukemia cells and inhibits the growth of triple-negative breast cancer cell lines or 3D triple-negative breast cancer models. MS8847 is applicable to research related to MLL-rearranged acute myeloid leukemia and triple-negative breast cancer.

In Vitro

MS8847 selectively targets EZH2-dependent cell growth and inhibits the proliferation of triple-negative breast cancer (TNBC) cells, with 5-day IC₅₀ values of 1.45 μM (BT549) and 0.45 μM (MDA-MB-468), respectively. It also inhibits the proliferation of MLL-r AML cell lines, with 5-day IC₅₀ values of 0.11 μM (EOL-1), 0.17 μM (MV4;11) and 0.41 μM (RS4;11), respectively^[1].
MS8847 (0.1-1 μM; 24 h) completely degrades EZH2 protein in EOL-1 MLL-r AML cells^[1].
MS8847 (1 nM-0.3 μM; 24 h) potently degrades EZH2 in a concentration-dependent manner in EOL-1 MLL-rAML cells, with a DC₅₀ of 34.4 nM, and also degrades EED and SUZ12^[1].
MS8847 (2.5-20 μM; 5 d) significantly inhibits cell growth and reduces spheroid size in a 3D in vitro BT549 TNBC model^[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.
