Chemical Adaptor Immunotherapy: Design, Synthesis, and Evaluation of Novel Integrin-Targeting Devices
摘要:
A series of beta-diketone derivatives of RGD peptidornimetics that selectively bind to alphabbeta3 and alphavbeta5 integrins were synthesized and covalently docked to the reactive lysine residues of monoclonal aldolase antibody 38C2. The resulting targeting devices strongly and selectively bound to human cancer cells expressing integrins alphavbeta3 and alphavbeta5 as analyzed by flow cytometry. In vitro and in vivo studies revealed that these novel integrin-targeting devices efficiently inhibit tumor growth. Thus, the combination of beta-diketone derivatives of RGD peptidomimetics that target cell surface integrins alphavbeta3 and alphavbeta5 with monoclonal aldolase antibodies through formation of a covalent bond of defined stoichiometry holds promise as a new approach to cancer therapy.

Cell-targeting conjugates of Saporin 6, a ribosome inactivating protein (RIP), were prepared using the Saporin Ala 157 Cys mutant, a small molecule inhibitor (SMI) of integrins αvβ3/αvβ5, and a potent cytotoxin, auristatin F (AF). The conjugates selectively and potently inhibited proliferation of tumorcells expressing the target integrins. We anticipate that the small molecule-RIP bioconjugate approach
使用Saporin Ala 157 Cys突变体,整合素αvβ3/αvβ5的小分子抑制剂(SMI)和有效的细胞毒素auristatin F(AF),制备了Saporin 6(核糖体失活蛋白(RIP))的细胞靶向缀合物。缀合物选择性地和有效地抑制表达靶整联蛋白的肿瘤细胞的增殖。我们预计,小分子-RIP生物共轭方法可广泛使用其他小分子药物。
