MS4322 (YS43-22) is a specific PRMT5 PROTAC degrader. MS4322 reduces the PRMT5 protein level with a DC₅₀ of 1.1 μM in MCF-7 cells. MS4322 inhibits the methyltransferase activity of PRMT5 with an IC₅₀ of 18 nM. MS4322 promotes ubiquitination and degradation of PRMT5. MS4322 can be used for the research of breast cancer, lung cancer, and hepatocellular cancer.

In Vitro

MS4322 (0.05-5 μM, 6 days) effectively reduces the PRMT5 protein level in a concentration dependent manner, with a D_max of 74 % in MCF-7 cells^[1].
MS4322 (5 μM, 7 days) degrades the PRMT5 protein through a PRMT5-, VHL-, and proteasome-dependent mechanism in MCF-7 cells^[1].
MS4322 (0.1-10 μM, 6 days) exhibits antiproliferative effect mainly because of its PRMT5 degradation activity but not its PRMT5 inhibitory activity in MCF-7 cells^[1].
MS4322 (5 μM, 6 days) also effectively reduces the PRMT5 protein level and inhibits growth in multiple cancer cell lines (HeLa, A549, A172, and Jurkat cells)^[1].

In Vivo

MS4322 (150 mg/kg, i.p., single dose, male Swiss albino mice) results in good exposure levels in plasma and reaches the highest plasma concentration (14 μM) 2 hours after administration. After 12 hours, the concentration of MS4322 is still above 100 nM. In addition, MS4322 is well tolerated in treated mice. ^[1].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 2.5 mg/mL (2.27 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (2.27 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

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.
