Definitions
- the present invention relates to integrin v? (3) A novel ⁇ -amino-hydroxyhydroxycarboxylic acid derivative having an antagonistic action, and a pharmaceutical composition containing at least one of these as an active ingredient.
- Integrins which are glycoprotein receptors involved in cell adhesion and penetrating the cell membrane, are not only involved in wound healing, hemostasis, phagocytosis, biological defense, cytoskeleton construction, but also themselves. It has been shown to be a signaling molecule (Cell, 69, 11, (1992)). Therefore, organic chemistry related to integrins has come into the spotlight in recent years, both in terms of medicinal chemistry, as well as molecular and cell biology.
- Integrin binds to various ligands while dynamically and intricately changing its conformation, and it is being understood that integrin transmits a signal in and out of the cell in both directions (Junichi Takagi et al. 50th Japan Society for Cell Biology, S5-l, 1997). In recent years, TA Springer of Harvard Medical School predicted that some integrin activated had a propeller structure, and that ligand binding was performed on the top surface of the propeller (Pro Natl. Acad. Sci. USA, 94, 65, 1997).
- Integurinhi V 5 3 many types of extracellular matrix, i.e. vitro-nectin, Fuiburino one Gen, fibronectin, Osuteoponchin, thrombospondin spondin, von Willebrand factor, and deeply involved ligand such as such as a biological function or development of the disease collagen It is very interesting as a drug discovery target because it binds to and forms a complex (DN & P, 10, 456 , 1997).

Okada et al., Am. J. Pathol., 149, 37, (1996)).
- integrin v- 3 antagonists from their chemical structures can be classified into antibodies, small peptides and their analogs, and small organic compounds. Both antagonists are structurally closely related to the sequence of the tripeptide RGD (arginine-glycine-aspartate), which is thought to be essential for its recognition when the ligand binds.
- Low-molecular peptide antagonists include disintegrin derived from snake venom, as well as cyclic peptides. One of them, GpenGRGDSPCA, inhibits smooth muscle migration and integrin v? It has been reported that blocking 3 actually reduces the intimal thickening of the egret (ET Choi et al., J. Vase.
