Disclosed is a class of multi-branched drug conjugates capable of specifically targeting CD44. The class of compounds specifically binds to CD44, and may target tumor cells and tissues having high expression of CD44, so that the concentration of the conjugate in a target tissue is high, the clinical treatment effect thereof is improved, and toxicity is reduced. The compound of the present invention is suitable for treating all tumors having high expression of CD44, comprising but not limited to gastric cancer, pancreatic cancer, small cell lung cancer, colon cancer, breast cancer, lung adenocarcinoma, liver cancer, nasopharyngeal carcinoma, malignant glioma, lymphoma, renal carcinoma, ovarian cancer, head and neck cancer, squamous cell carcinoma, and the like.
本文披露了一类多支链药物结合物,能够特异性靶向CD44。这类化合物特异性结合CD44,并且可能靶向具有高CD44表达的肿瘤细胞和组织,使得结合物在目标组织中的浓度高,从而提高临床治疗效果,减少毒性。本发明的化合物适用于治疗所有具有高CD44表达的肿瘤,包括但不限于胃癌、胰腺癌、小细胞肺癌、结肠癌、乳腺癌、肺腺癌、肝癌、鼻咽癌、恶性胶质瘤、淋巴瘤、肾癌、卵巢癌、头颈癌、鳞状细胞癌等。
