Biological Activity

R547 is a potent and selective ATP-competitive CDK inhibitor.In cell-free assays, R547 effectively inhibited CDK1/cyclin B, CDK2/cyclin E, and CDK4/cyclin D1 (Ki = 1–3 nmol/L) and was inactive (Ki > 5,000 nmol/L) against a panel of >120 unrelated kinases. In vitro, R547 effectively inhibited the proliferation of tumor cell lines independent of multidrug resistant status, histologic type, retinoblastoma protein, or p53 status, with IC50s ≤ 0.60 μmol/L.

Source Oncogene (2012). Figure 6. R547
Method I.P.
Cell Lines p27−/− male mice
Concentrations 20 mg/kg
Incubation Time 13 day
Results Strikingly, R547 reduced dysplasia (Figure 6D) and also modestly reduced ectopic mitoses but had no effect on progenitor mitoses that are distant or adjacent to phalloidin-marked apical membranes, respectively
Cell Experiment
Cell lines human tumor cell lines HCT116, H460a, MDA-MB-435, DU145, LOX, and A549
Preparation method Tetrazolium Dye Proliferation [3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide] Assay
Concentrations 0~1 μM
Incubation time 48 h
Animal Experiment
Animal models HCT116, H460a, MDA-MB-435, DU145, LOX, and A549
Formulation Oral R547 was formulated as a suspension in Klucel LF/Tween 80, and i.v. R547 was formulated as a solution in hydroxylpropyl β-cyclodextrin, sodium hydroxide, and water for i.v. injection
Dosages 40 mg/kg daily oral dosing and 40 mg/kg i.v. once weekly
Administration oral or i.v.

Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
