Biological Activity

ATN-161 is a novel small peptide inhibitor of integrin α5β1; a beta integrin antagonist with antitumor activity. ATN-161 inhibited VEGF-induced migration and capillary tube formation in hCECs. In vivo, injection of ATN-161 after laser photocoagulation inhibited CNV leakage and neovascularization to an extent similar to AF564. Furthermore, SD-OCT and histologic examinations indicated that ATN-161 significantly decreased the size of laser-induced lesions. Treatment with the α5β1 signaling inhibitor ATN-161 significantly blunts atherosclerotic plaque development in apolipoprotein E-deficient mice, characterized by reduced vascular cell adhesion molecule-1 expression and macrophage accumulation without affecting fibrous cap size.

Customer Product Validations & Biological Datas
Source Graefes Arch Clin Exp Ophthalmol (2018). Figure 2. ATN-161
Method western blot assay
Cell Lines Tet/opsin/VEGF mice
Concentrations 0.1, 1, and 10 μg/μL
Incubation Time 24 h
Results The analysis of western blot results revealed that ATN-161 significantly reduced the expression of integrin 5β1 at concentrations of 1 and 10 μg/μL, and this seemed to present a dose-independent manner
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B 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.
