Description of RRD-251

RRD-251 is an inhibitor of retinoblastoma tumor suppressor protein (Rb)-Raf-1 interaction, with potent anti-proliferative, anti-angiogenic and anti-tumor activities[1].

RRD-251 (10-50 μM; 24 hours) inhibits melanoma growth in-vitro[1].RRD-251 (50 μM; 2 hours) inhibits Rb-Raf-1 interaction and Rb phosphorylation in non-small cell lung cancer cells[1]. RRD-251 induces apoptosis (50 μM; 18 hours) and cell cycle arrest (20-50 μM; 4 hours)[1].RRD-251 alters the expression of cell cycle and apoptosis regulatory protein[1].

RRD-251 (50 mg/kg; i.p.; q.o.d; for 14 days) has anti-cancer activities in vivo on melanomas[1].

Calculation results:

Working concentration: mg/ml;

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 saline, 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.
3. All of the above co-solvents are available for purchase on the GlpBio website.
