Abstract Bispecific chimeras bridging cell membrane proteins with lysosome‐trafficking receptors (LTRs) provide an effective therapeutic approach through lysosomal degradation of disease‐relevant targets. Here, we report a novel dendronized DNA chimera (DENTAC) strategy that uses dendritic to engage surface scavenger (SRs) as LTR. Using bioorthogonal strain‐promoted alkyne‐azide cycloaddition conjugate the protein binder, resulting DENTAC is able traffic target into lysosome for elimination. We demonstrated utility by degrading oncogenic nucleolin (NCL) and epidermal growth factor receptor (EGFR). The anti‐cancer application NCL‐targeting was validated in mouse xenograft model lung cancer. This work thus presents new avenue rapid development potent degraders against proteins, also broad research prospects.

The lysosome-targeting chimera (LYTAC) strategy provided a very powerful tool for the degradation of membrane proteins. However, synthesis LYTACs, antibody-small molecule conjugates, is challenging. ability antibody-based LYTACs to penetrate solid tumor limited as well, especially cross blood-brain barrier (BBB). Here, we propose covalent chimeric peptide-based targeted platform (Pep-TACs) by introducing long flexible aryl sulfonyl fluoride group, which allows proximity-enabled cross-linking upon binding with protein interest. Pep-TACs facilitates target proteins through mechanism recycling transferrin receptor (TFRC)-mediated lysosomal endocytosis. Biological experiments demonstrate that can significantly degrade expression PD-L1 on cells, dendritic cells and macrophages, under acidic conditions, markedly enhance function T phagocytosis macrophages. Furthermore, both in anti-PD-1-responsive -resistant models, exert significant anti-tumor immune response. It noteworthy BBB prolong survival mice situ brain tumor. As proof-of-concept, this study introduces modular TFRC-based peptide protein, immunotherapy tumors.

Abstract Proteolysis targeting chimera (PROTAC) is an emerging pharmacological modality with innovated post‐translational protein degradation capabilities. However, off‐target induced unintended tissue effects and intrinsic “hook effect” hinder PROTAC biotechnology to be maturely developed. Herein, intracellular fabricated nano proteolysis chimeras (Nano‐PROTACs) a center‐spoke network for achieving efficient dose‐dependent in tumor reported. The precursors are triggered by higher GSH concentrations inside cells, which subsequently situ self‐assemble into Nano‐PROTACs through intermolecular hydrogen bond interactions. fibrous can form effective polynary complexes E3 ligases multi‐binding sites, “anti‐hook effect”. generality efficacy of validated degrading variable interest (POI) such as epidermal growth factor receptor (EGFR) androgen (AR) wide‐range manner 95 % rate long‐lasting potency up 72 h vitro. Significantly, achieve vivo 79 inhibition A549 LNCap xenograft mice models, respectively.

Immune checkpoint blockade (ICB) therapy, while achieving tremendous clinical successes, still suffers from a low objective response rate in cancer treatment. As proof-of-concept study, we propose new immune degradation (ICD) therapy relying on lysosome-targeting chimera (LYTAC) to deplete programmed death ligand-1 (PD-L1) the tumor cell surface. Our designed chimeric aptamer one side targets lysosome-trafficking receptor, and other allows biorthogonal covalent-conjugation-reinforced specific binding of PD-L1. This covalent LYTAC is able hijack PD-L1 for lysosomal with greatly improved efficiency over its noncovalent counterpart complex vivo environment. Beyond abolishing PD-1/PD-L1 axis associated resistance, demonstrate first time that LYTAC-triggered could directly cause immunogenic apoptosis cells elicit tumor-specific responses, offering unparalleled advantages ICB antibody therapy. Remarkably, ICD achieves comparable or higher antitumor efficacy causing significantly less inflammatory injury compared antibody-based Moreover, can serve as general platform specifically degrading membrane-associated proteins, making it promising tool future applications. work presents novel molecular effective environments, valuable insights pushing DNA-based drugs toward
