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	CECR2 ^[1] 17 nM BRD9 ^[1] 0.122 μM BRD4 ^[1] 0.29 μM BRD2 ^[1] 0.41 μM
In vitro	In cell-based assays, Bromosporine (1 µM) accelerates FRAP recovery of BRD4 and CREBBP, while shows no activities against TIF1α, BAZ2A, and SMARCA2 even at 10 µM. This compound shows moderate cytotoxicity in HeLa cells at 18 µM. It, as a chemical probe for bromodomain functional assays, will be very useful in elucidating further biological roles of reader domains. ^[2]
