  • Patent number: 7943728
    Abstract: Disintegrin variants and pharmaceutical uses thereof are disclosed. The disintegrin variant includes an isolated polypeptide that has integrin ?v?3 receptor-antagonist activity and substantially reduced integrin ?llb?3 and/or ?5?1 receptor-blocking activity as compared to a wild-type disintegrin. The variant is encoded by a modified disintegrin nucleotide sequence that encodes a modified amino acid sequence, resulting in a polypeptide having substantially reduced affinity to integrin ?llb?3 and/or ?5?1 as compared to a wild-type disintegrin. The variant is useful for treatment and/or prevention of ?v?3 integrin-associated diseases in a mammal, which include osteoporosis, bone tumor or cancer growth, angiogenesis-related tumor growth and metastasis, tumor metastasis in bone, malignancy-induced hypercalcemia, angiogenesis-related eye diseases, Paget's disease, rheumatic arthritis, and osteoarthritis.
