Description of (S)-CR8

(S)-CR8 is a second generation derivative of (R)-roscovitine and an inhibitor of cyclin-dependent kinase 1 (Cdk1/cyclin B), Cdk2/cyclin A, Cdk2/cyclin E, Cdk5/p25, and Cdk9/cyclin T (IC50s = 0.15, 0.08, 0.06, 0.12, and 0.11 µM, respectively).1 It also inhibits casein kinase CK1δ/ε (CKδ/ε) and DYRK1A (IC50s = 0.61 and 0.9 µM, respectively). (S)-CR8 reduces cell viability in human neuroblastoma cell lines, including SH-SY5Y, SK-N-AS, SK-N-BE, and IMR32 cells (IC50s = 0.43, 1.46, 0.13, and 0.14 µM, respectively).2 It also reduces protein levels of the survival factor Mcl-1 in SH-SY5Y cells.

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 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.
