YZ-17

YZ-17 is a PROTAC degrader targeting PRMT5, with DC₅₀ = 2.2 μM (HCC1806 cells). YZ-17 recruits CRBN E3 ligase and induces PRMT5 degradation through the ubiquitin-proteasome system, inhibiting PRMT5-mediated symmetric dimethylarginine modification. YZ-17 co-degrades the PRMT5 adaptor protein MEP50 via a CRBN-dependent mechanism. YZ-17 induces G1 phase cell cycle arrest and inhibits colony formation in cancer cells. YZ-17 exhibits antiproliferative activity in various cancer cells. YZ-17 shows antitumor efficacy in a triple-negative breast cancer xenograft mouse model. YZ-17 can be used for research on triple-negative breast cancer.

In Vitro

YZ-17 (1-5 μM; 12 h) achieves 61.29% PRMT5 degradation at 5 μM in HCC1806 cells^[1].
YZ-17 (0.5-6.0 μM; 24 h) potently degrades PRMT5 (DC₅₀ = 2.2 μM) and its associated adaptor protein MEP50 (DC₅₀ = 2.0 μM) in HCC1806 cells, and degrades PRMT5 (DC₅₀ = 3.3 μM) and MEP50 (DC₅₀ = 2.9 μM) in HCC1937 cells^[1].
YZ-17 (0.5-6.0 μM; 24 h) effectively inhibits the catalytic activity of PRMT5, and treatment at 6 μM for 24 h almost completely eliminates PRMT5-dependent sDMA modification in HCC1806 cells^[1].
YZ-17 (4.5 μM; 6-36 h) degrades PRMT5 and MEP50 in a time-dependent manner, with nearly complete elimination of both proteins in HCC1806 and HCC1937 cells after treatment at 4.5 μM for 36 h^[1].
YZ-17 (4.5 μM; 24 h initial treatment, followed by 6 h co-incubation period) mediates the degradation of PRMT5 and MEP50 through a classic PROTAC mechanism, a process that requires simultaneous binding to CRBN and PRMT5 and depends on an intact ubiquitin-proteasome system^[1].
YZ-17 (0-8.0 μM; 24 h) exhibits potent and selective antiproliferative activity against triple-negative breast cancer cell lines (IC₅₀ range: 2.6-3.7 μM), with minimal toxicity to normal mammary epithelial MCF10A cells^[1].
YZ-17 (1-5 μM; 24 h) induces concentration-dependent G1 phase cell cycle arrest in HCC1806 and HCC1937 triple-negative breast cancer cells^[1].
YZ-17 (0.5-2.0 μM; 24 h initial treatment, followed by 14 days of culture without treatment) potently and persistently inhibits the clonogenic growth of triple-negative breast cancer cells, almost completely eliminating colony formation in HCC1806 and HCC1937 cells at 2 μM^[1].
YZ-17 (1-5 μM; 48 h) inhibits the proliferation of HCC1806 triple-negative breast cancer cells by up to 96.0% after 48 h of treatment at a concentration of 5 μM^[1].

Cell Line:

HCC1806 triple-negative breast cancer cells
Concentration:

4.5 μM
Incubation Time:

24 h initial treatment, followed by 6 h co-incubation period

Was significantly attenuated in its induced PRMT5 and MEP50 degradation by the CRBN ligand pomalidomide, the NEDD8-activating enzyme inhibitor MLN4924, the proteasome inhibitor MG132, and the parental PRMT5 inhibitor PJ-68, confirming the degradation process is dependent on CRBN recruitment, functional cullin neddylation, active proteasome function, and direct PRMT5 binding by YZ-17.

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.
