Description

MRTX9768 hydrochloride is a potent, selective, orally active, first-in-class PRMT5-MTA complex inhibitor^[1].

IC₅₀ & Target

PRMT5•MTA^[1]

In Vitro

MRTX9768 inhibits SDMA and cell proliferation in HCT116 MTAP-del cells (SDMA IC₅₀ 3 nM; prolif. IC₅₀ 11 nM) with marked selectivity over HCT116 MTAP-WT cells (SDMA IC₅₀ 544 nM; prolif. IC₅₀ 861 nM)^[1].
MRTX9768 (0-250 nM) results in LU99 SDMA inhibition maintaining after 3-hr drug treatment followed by 4-day washout (exhibiting tight binding and prolonged PRMT5•MTA occupancy)^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

In xenograft studies, oral administration of MRTX9768 demonstrates dose-dependent inhibition of SDMA in MTAP-del tumors, with less SDMA modulation observed in bone marrow^[1].
MRTX9768 selectively targets MTAP/CDKN2A-deleted tumors (such as glioblastoma)^[1]^[2].
MRTX9768 (PO dose 30 mg/kg in CD-1 mouse and beagle dog, 10 mg/kg in cynomolgus monkey) has a favorable ADME profile (>50% bioavailability in mice and dogs, moderate to high clearance, No changes in RBC parameters when administered well above efficacious concentrations (1000 mg/kg))^[3].
MRTX9768 (100 mg/kg, orally, BID, 6/21 days) results in SDMA inhibition maintaining 3 days after dosing is stopped^[3].

* Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture and light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

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: ≥ 4.5 mg/mL (9.76 mM); Clear solution

This protocol yields a clear solution of ≥ 4.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (45.0 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.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 4.5 mg/mL (9.76 mM); Clear solution

This protocol yields a clear solution of ≥ 4.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (45.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 4.5 mg/mL (9.76 mM); Clear solution

This protocol yields a clear solution of ≥ 4.5 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 (45.0 mg/mL) to 900 μL Corn oil, and mix evenly.
