The present invention provides folate receptor binding ligand‐drug delivery conjugates having the formula (F) nL1L2D. The conjugates have high affinity to folate receptor‐positive tumor cells and low toxicity for normal cells. The present invention also relates to preparation methods for such conjugates, pharmaceutical compositions comprising such conjugates, and use of such conjugates for preparing anti‐tumor medicaments.
本发明提供了具有公式(F)nL1
L2D的叶酸受体结合
配体-药物传递共轭物。这些共轭物对叶酸受体阳性肿瘤细胞具有高亲和力,对正常细胞毒性低。本发明还涉及这些共轭物的制备方法、包含这些共轭物的药物组合物,以及利用这些共轭物制备
抗肿瘤药物的用途。
