  Preparation and Evaluation of Radiolabeled Antibody Recruiting Small Molecules That Target Prostate-Specific Membrane Antigen for Combined Radiotherapy and Immunotherapy

  摘要：

  The feasibility of developing a single agent that can deliver radioactive iodine and also direct cellular immune function by engaging endogenous antibodies as an antibody-recruiting small molecule (ARM) was determined. A library of new prostate-specific membrane antigen (PSMA)-binding ligands that contained antibody-recruiting 2,4-dinitrophenyl (DNP) groups and iodine were synthesized and screened in vitro and in vivo. A lead compound (9b) showed high affinity for PSMA and the ability to bind anti-DNP antibodies. Biodistribution studies of the iodine-125 analogue showed 3% ID/g in LNCaP xenograft tumors at 1 h postinjection with tumor-to-blood and tumor-to-muscle ratios of 10:1 and 44:1, respectively. The radiolabeled analogue was bound and internalized by LNCaP cells, with both functions blocked using a known PSMA inhibitor. A second candidate showed high tumor uptake (>10% ID/g) but had minimal binding to anti-DNP antibodies. The compounds reported represent the first examples of small molecules developed specifically for combination immunotherapy and radiotherapy for prostate cancer.

  The present invention provides, in one aspect, bifunctional compounds that can be used to promote or enhance degradation of certain circulating proteins. In another aspect, the present invention provides bifunctional compounds that can be used to promote or enhance degradation of certain autoantibodies. In certain embodiments, treatment or management of a disease and/or disorder requires degradation, removal, or reduction in concentration of the circulating protein or the autoantibody in the subject. Thus, in certain embodiments, administration of a compound of the invention to the subject removes or reduces the circulation concentration of the circulating protein or the autoantibody, thus treating, ameliorating, or preventing the disease and/or disorder. In certain embodiments, the circulating protein is TNF.

  Herein we describe the sequential synthesis of a variety of azide-alkyne click chemistry-compatible heterobifunctional oligo(ethylene glycol) (OEG) linkers for bioconjugation chemistry applications. Synthesis of these bioorthogonal linkers was accomplished through desymmetrization of OEGs by conversion of one of the hydroxyl groups to either an alkyne or azido functionality. The remaining distal hydroxyl group on the OEGs was activated by either a 4-nitrophenyl carbonate or a mesylate (–OMs) group. The –OMs functional group served as a useful precursor to form a variety of heterobifunctionalized OEG linkers containing different highly reactive end groups, e.g., iodo, –NH2, –SH and maleimido, that were orthogonal to the alkyne or azido functional group. Also, the alkyne- and azide-terminated OEGs are useful for generating larger discrete poly(ethylene glycol) (PEG) linkers (e.g., PEG16 and PEG24) by employing a Cu(I)-catalyzed 1,3-dipolar cycloaddition click reaction. The utility of these clickable heterobifunctional OEGs in bioconjugation chemistry was demonstrated by attachment of the integrin (αvβ3) receptor targeting peptide, cyclo-(Arg-Gly-Asp-D-Phe-Lys) (cRGfKD) and to the fluorescent probe sulfo-rhodamine B. The synthetic methodology presented herein is suitable for the large scale production of several novel heterobifunctionalized OEGs from readily available and inexpensive starting materials.

  在此，我们描述了一系列适用于叠氮-炔烃点击化学的异双功能寡（乙烯）醇（OEG）连接子 sequential synthesis，用于生物偶联化学应用。这些生物正交连接子的合成是通过将OEG中的一个羟基转化为炔烃或叠氮功能团，进而进行去对称化来完成的。OEG上的远端羟基则通过4-硝基苯基碳酸酯或美克酸酯（–OMs）基团进行活化。–OMs功能团作为一种有用的前驱体，用于形成包含不同高度反应性末端基团的多种异双功能化OEG连接子，例如：碘、–NH2、–SH和马来酰亚胺，这些基团与炔烃或叠氮功能团具有正交性。此外，炔烃和叠氮末端的OEG可通过采用Cu(I)催化的1,3-偶极环加成点击反应生成更大的离散聚（乙烯）醇（PEG）连接子（例如，PEG16和PEG24）。通过将整合素（αvβ3）受体靶向肽环（Arg-Gly-Asp-D-Phe-Lys）（cRGfKD）和荧光探针硫酸铑胺B附着于这些可点击的异双功能OEG中，证明了它们在生物偶联化学中的实用性。本文所呈现的合成方法适合于从易得且廉价的起始材料大规模生产多种新型异双功能化OEG。

  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.
