Biological Activity

Description RO3280 (Ro5203280) is a potent, highly selective inhibitor of Polo-like kinase 1 (PLK1) with IC50 of 3 nM.
Features A selective PLK1 inhibitor. Demonstrates greater potency than BI2536. Potential use in nasopharyngeal carcinomas.
Targets
PLK1 [1]
3 nM
In vitro
In vitro RO3280 shows the strong anti-proliferative activity against lung cancer cell line H82, colorectal cancer cell HT-29, breast cancer cell MDA-MB-468, prostate cancer cell PC3 and skin cancer cell A375 with IC50s of 5, 10, 19, 12 and 70 nM, respectively. [1]
In Vivo
In vivo RO3280 displays robust antitumor activity in nude mouse implanted with HT-29 human colorectal tumors ranging from 72% tumor growth inhibition when dosed once weekly at 40 mg/kg, to complete tumor regression when dosed more frequently.. [1]

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.
