Saracatinib (AZD0530) is a highly selective, orally available, dual-specific Src/Abl kinase inhibitor with IC50 of 2.7 and 30 nM for c-Src and Abl kinase, respectively.Saracatinib (AZD0530) demonstrated potent antimigratory and antiinvasive effects in vitro, and inhibited metastasis in a murine model of bladder cancer. Antiproliferative activity of AZD0530 in vitro varied between cell lines (IC50=0.2 ~10 mM).
|Cell lines||Calu-6, A549, LoVo, SW 403, HT29, HCT 116 and other cells line|
|Preparation method||Cell proliferation was assessed using a colorimetric 5-bromo- 20 -deoxyuridine (BrdU) Cell Proliferation ELISA kit (Roche Diagnostics GmbH), as described previously (Ple´ et al., 2004). Briefly, cells were plated onto 96-well plates (1.5*104 cells/ well), the following day 0.039–20 μM AZD0530 in DMSO (at a final concentration of 0.5%) was added and the cells were incubated for 24 h. The cells were pulse labeled with BrdU for 2 h and fixed. Cellular DNA was then denatured with the provided solution and incubated with antiBrdU peroxidase for 90 min. Following three washes with phosphate-buffered saline, tetramethylbenzidine substrate solution was added and the plates were incubated on a plate shaker for 10–30 min until the positive control absorbance at 690 nm was approximately 1.5 absorbance units.|
|Incubation time||24 h|
|Animal models||female nude mice bearing LoVo tumors, Src3T3 allografts and human NSCLC (Calu-6) xenografts|
|Dosages||6.25–50 mg/kg for 10–91 days|
|Body Surface Area (m2)||0.007||0.025||0.15||0.05||0.02||0.5|
|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.
