The invention is related to medicine, in particular, to oncology and immunology. The novel compounds of the general formula 1 or 2, exhibiting affinity for CD16a receptor have been proposed. There were also proposed novel modified proteins active towards CD16a receptor, selected from antibody or autogen conjugated by a modifying compound selected from compound of the general formula 1 or 2, which stimulate and direct antibody-dependent cellular cytotoxicity. The novel modified proteins (conjugates) could be used for destruction of definite targeted group of cells in organism, for example, cancerous cells or autoimmune lymphocytes. There were also proposed methods for conjugate preparation, pharmaceutical composition, and medicament, comprising modified proteins for treating oncology and autoimmune diseases.
本发明涉及医学,特别是肿瘤学和免疫学。已经提出了对 CD16a 受体具有亲和力的通式 1 或 2 的新型化合物。此外,还提出了对 CD16a 受体具有活性的新型修饰蛋白,这些蛋白选自抗体或自体原,与选自通式 1 或 2 化合物的修饰化合物共轭,可刺激和引导抗体依赖性细胞毒性。新型修饰蛋白(共轭物)可用于消灭生物体内的特定目标细胞群,例如癌细胞或自身免疫淋巴细胞。此外,还提出了包含修饰蛋白质的共轭物制备方法、药物组合物和药品,用于治疗肿瘤和自身免疫性疾病。
