Biological Activity

SU5416 (Semaxanib) is a potent and selective vascular endothelial growth factor (VEGF) receptor protein tyrosine kinase 1/2 inhibitor that also inhibits other tyrosine kinases KIT, MET, FLT3 and RET. SU5416 inhibited cell migration of human vascular endothelial cells expressing both Flt-1 and KDR in response to VEGF and also inhibited the cell migration in response to placenta growth factor (PIGF), a specific ligand for Flt-1. Chemotaxis of monocytes expressing only Flt-1 was also inhibited by SU5416 in a dose-dependent manner. Moreover, SU5416 was found to inhibit tyrosine kinase of Flt-1 in response to PIGF in vitro. SU5416 efficiently inhibited Kit activity in vivo when administered on a twice-weekly schedule.

Method western blotting
Cell Lines endothelial cells (HUVEC) and 2H11 cells
Concentrations 1 μM
Incubation Time 24 h
Results accumulation of cyclin B1 involved in the G2/M transition, whereas SU5416 alone reduced the expression of the regulator. In contrast, cyclin B1 expression was attenuated by 24 h of SU5416 treatment, regardless of the radiation dose.

Results Notably, 48 h of SU5416 and radiation exposure significantly increased the percentage of early apoptotic cells in endothelial cell lines.
Cell Experiment
Cell lines C6, Calu 6, A375, A431, and SF767T
Preparation method Tumor Cell Lines and Growth Assays. The EPH4-VEGF cell line is a murine epithelial cell line engineered to overexpress murine VEGF. EPH4-VEGF cells were cultured in DMEM/F-12; C6 cells were cultured in Ham’s F-10 and A375, A431, and LNCAP cells in DMEM. All of these cultures were supplemented with 10% FBS and 2 mM L-glutamine. Calu 6 and SF767T cells were cultured in MEM supplemented with 10% FBS, 2 mM L-glutamine, 1 mM sodium pyruvate, and 0.1 mM MEM nonessential amino acids solution. C6, Calu 6, A375, A431, and SF767T were plated in their respective growth medium at 2 × 103 cells/100 μl/well in 96-well, flat-bottomed plates. SU5416 was serially diluted in media containing DMSO (<0.5%) and added to cultures of tumor cells 1 day after the initiation of culture. Cell growth was measured after 96 h using the sulforhodamine B method. IC50s were calculated by curve fitting using four-parameter analysis.

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.
