Biological Activity
| Targets | αvβ3 2.74 nM (IC50) |
| ln Vitro | In comparison to the PBS control group, HSDVHK dramatically reduced the bFGF-induced cell migration[1]. Since HSDVHK-NH2 (P11) is inactive for the complex formation of a denatured version of integrin–vitronectin, its recognition of the Arg-Gly-Asp (RGD)-binding site is site-specific. At an IC50 value of 25.72 nM, HSDVHK-NH2 (P11) exhibits substantial antagonistic activity against the avb3-GRGDSP interaction[2]. By inducing HUVEC cell death by caspase activations, HSDVHK-NH2 (P11) suppresses HUVEC proliferation. This mechanism is associated with enhanced p53 expression[3]. |
| Cell Assay |
Cell Proliferation Assay [3] Cell Types: HUVEC cells. Tested Concentrations: 0.1, 1, 10, and 100 μg/mL. Incubation Duration: 72 h. Experimental Results: Dramatically inhibited HUVEC proliferation on denatured collagen-coated plates in a dose-dependent manner. |
