Developing selective strategies to treat metastatic cancers remains a significant challenge. Herein, we report the first antibody‐recruiting small molecule (ARM) that is capable of recognizing the urokinase‐type plasminogen activator receptor (uPAR), a uniquely overexpressed cancer cell‐surface marker, and facilitating the immune‐mediated destruction of cancer cells.

制定治疗转移性癌症的选择性策略仍然是一项重大挑战。在此,我们报道了首个能够识别尿激酶型纤溶酶原激活物受体(uPAR)(一种独特的过表达的癌细胞表面标志物)并促进免疫介导的癌细胞破坏的抗体招募小分子(ARM)。获得了ARM-U2 / uPAR复合物的共晶体结构,代表了与非肽配体复合的uPAR的第一个晶体结构。最后,我们证明了ARM-U2与照护标准药物阿霉素不同,在没有体重减轻迹象的情况下可在体内显着抑制肿瘤生长。这项工作强调了抗体募集分子作为治疗癌症的免疫疗法的前景。
