Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	PRMT5 ^[1] (Cell-free assay) 22 nM PRMT5 ^[1] (Cell-based assay) 25 nM
In vitro	LLY-283 inhibits PRMT5 enzymatic activity in vitro and in cells with IC50 of 22 ± 3 and 25 ± 1 nM, respectively. This compound directly binds to and occupies the SAM pocket. It is a low nanomolar enzymatic inhibitor of the PRMT5:MEP50 complex in biochemical assays and is selective for PRMT5 over other methyltransferases including related family members.^[1]
In vivo	LLY-283 shows antitumor activity in mouse xenografts when dosed orally and can serve as an excellent probe molecule for understanding the biological function of PRMT5 in normal and cancer cells. This compound can be used as an in vivo tool compound to evaluate the pharmacology of PRMT5 inhibition.^[1]
