Definitions
- the present invention relates to novel compounds having aminothiazole structure, more specifically, novel compounds for inhibition of VEGF receptor 2 kinase (hereinafter, referred to as "VEGFR2 kinase” or “KDR”) activity, as will be illustrated in Formula 1 later, or a pharmaceutically acceptable salt thereof.
- VEGFR2 kinase VEGF receptor 2 kinase
- KDR VEGF receptor 2 kinase
- the compounds according to the present invention is useful for the treatment and prevention of diseases resulting from the undesired KDR, particularly angiogenesis-related diseases activity,
- Angiogenesis referring to the physiological mechanism that makes new blood vessels for providing nutrients and oxygen necessary for cell survival and eliminating waste materials therefrom, allows only 0.01 % of blood vessel cells to proliferate under a normal condition, thereby recovering wounded parts in blood vessels (Carmeliet et al.,
- angiogenesis is further required.
- solid tumors cannot practically grow over a certain size (e.g., about 100 - 200 ⁇ m in diameter). That is because there is a limit on the distance that nutrients or oxygen can reach cells by diffusion (so-called, diffusion limit) (Carmeliet et ah, 2000, Nature 407:249-257).
- cancer cells distant from blood vessels become under the hypoxia condition due to the deficiency of oxygen.
- cancer cells or stromal cells secrete various pro-angiogenic factors to induce angiogenesis toward a solid cancer.
- pro-angiogenic factors there are VEGF (Vascular Endothelial Growth Factor), bFGF (basic Fibroblast Growth factor), PDGF (Platelet-derived growth factor), and the like.
- VEGF Vascular Endothelial Growth Factor
- bFGF basic Fibroblast Growth factor
- PDGF Platinum-derived growth factor
- Rheumatoid arthritis refers to the disease that capillary vessels created newly while arthritis proceeding to chronic inflammatory disease invade articulation to destroy cartilaginous tissues.
- diabetic retinopathy refers to the disease caused by invasion of capillary vessels into the vitreous body of retina. It is known that pre-angiogenic factors are secreted from ischemic retina to cause the diabetic retinopathy. Since eyes are tissues with most rarely blood vessels in body, angiogenesis results in directly the loss of eyesight. As such, the ultimate therapy can be achieved only by prevention of angiogenesis (Carmeliet P., 2000, Nature Medicine 6: 389-395, Aiello L. P., 2000, Nature Medicine 6: 379-381).
- Angiogenesis receptor tyrosine kinases as receptors of pro-angiogenic factors, such as VEGFR2 (KDR), FGFRl, PDGFR- ⁇ and the like, draw an attention as a target for development of anti-angiogenesis drugs.
- anti-angiogenesis drugs exhibit the effect of inhibiting the activity of VEGFR2 (KDR) and simultaneously also inhibiting the activity of other angiogenesis RTK families. This combined inhibiting effect is known as one mechanism of significantly increasing the angiogenesis inhibiting effect (Adams et al., 2002, Current Opinion in Chemical Biology, 5:486-492). Therefore, many researches are being carried out to find compounds useful in the treatment and prevention of angiogenesis-related diseases such as cancers, rheumatoid arthritis, diabetic retinopathy, etc.
- the inventors of the present invention while carrying out extensive researches and many experiments, could synthesize novel compounds capable of inhibiting the KDR activity and, after measuring their inhibition abilities, found that they can be used in treatment or prevention of diseases resulting from the undesired activation of KDR, for example, angiogenesis-related diseases, such as cancers, psoriasis, rheumatoid arthritis, diabetic retinopathy, etc.
- angiogenesis-related diseases such as cancers, psoriasis, rheumatoid arthritis, diabetic retinopathy, etc.

Abstract
L'invention porte sur des composés permettant d'inhiber des kinases de tyrosine du récepteur d'angiogenèse, notamment l'activité de la kinase 2 (« KDR ») du récepteur VEG et sur des procédés de préparation et d'utilisation afférents. L'invention porte également sur des compositions pharmaceutiques les renfermant en une dose thérapeutiquement efficace. Les composés selon l'invention sont utiles pour traiter et prévenir des maladies provoquées par une activité KRD non désirée, notamment des maladies liées à l'angiogenèse, telles que des cancers, le psoriasis, la polyarthrite rumatoïde, la rétinopathie diabétique, etc.
