The present invention relates to compounds which function as antibody mimetic compounds. These compounds are bifunctional/multifunctional compounds which contain at least one cancer cell binding moiety which selectively binds to prostate specific membrane antigen (PSMA) and a FC receptor binding moiety which modulates an FC immune receptor, preferably a FcγRI receptor. Compounds according to the present invention bind selectively to cancer cells which upregulate PSMA and through that interaction, place the Fc receptor binding moiety of the compound in proximity to a Fc receptor, preferably a FcγRI receptor, which can modulate (preferably, upregulate) a humoral response in a patient to cancer cells. Through this biological action of the compounds according to the present invention, cancer cells, including metastatic cancer cells, especially prostate cancer cells can be immune regulated, resulting in the favorable therapy of cancer in a patient. Methods of using these compounds to treat cancer and/or reduce the likelihood of metastatis of cancer are additional aspects of the present invention.
本发明涉及具有抗体模拟功能的化合物。这些化合物是双功能/多功能化合物,至少含有一个选择性结合前列腺特异性膜抗原(PSMA)的癌细胞结合分子和一个调节 FC 免疫受体(最好是 FcγRI 受体)的 FC 受体结合分子。根据本发明的化合物可选择性地与上调 PSMA 的癌细胞结合,并通过这种相互作用,将化合物的 Fc 受体结合分子置于 Fc 受体(最好是 FcγRI 受体)附近,从而调节(最好是上调)患者对癌细胞的体液反应。通过根据本发明的化合物的这种生物作用,癌细胞,包括转移性癌细胞,尤其是前列腺癌细胞可以被免疫调节,从而有利于患者的癌症治疗。使用这些化合物治疗癌症和/或降低癌症转移可能性的方法是本发明的其他方面。
