摘要:
"Albumin-binding arginine deiminase fusion protein, method for producing the protein, and pharmaceutical composition comprising the protein". The present invention relates to a pharmaceutical composition containing the albumin-binding arginine deiminase fusion protein (aad) for the treatment of cancer or other arginine-dependent diseases. aad fusion protein can be purified from soluble and insoluble crude protein fractions, it binds to human serum albumin (hsa) and has a longer half-life with its high activity for efficient arginine depletion in cells. cancerous. The specific wild type adi and aad activities of the present invention are 8.4 and 9.2 µ / mg (in physiological pH 7.4), respectively. The aad used in the present invention may be used in the treatment of various cancers (e.g., pancreatic cancer, leukemia, head and neck cancer, colorectal cancer, lung cancer, breast cancer, liver cancer, nasopharyngeal cancer, cancer esophagus, prostate cancer, stomach cancer and brain cancer) and in the cure of arginine-dependent diseases. The composition may be used alone or in combination with at least one chemotherapeutic agent to provide a synergistic effect on cancer treatment and / or metastasis inhibition. 1/1resumo “proteína de fusão arginina deiminase de ligação à albumina, método para produzir a proteína, e composição farmacêutica compreendendo a proteína”. a presente invenção se refere a uma composição farmacêutica contendo a proteína de fusão arginina deiminase de ligação à albumina (aad) para o tratamento de câncer ou de outras doenças arginina-dependentes. a proteína de fusão aad pode ser purificada a partir de frações solúveis e insolúveis de proteínas brutas, ela se liga à albumina de soro humano (hsa) e apresenta uma meia-vida mais longa com sua alta atividade para uma depleção eficiente de arginina em células cancerosas. as atividades específicas da adi do tipo selvagem e da aad da presente invenção são 8,4 e 9,2 u/mg (em ph fisiológico 7,4), respectivame
