Abstract The ability of cytokine receptors to mediate the internalization targets in lysosomes positions them as specific and effective effectors for protein degradation strategies. However, challenges remain, including potential unintended activation cell‐proliferation‐related receptors, well limitations programmability structural flexibility degradators. In this work, a CXCR7‐targeting chimera (AP‐CRTAC) that functions CXCR7 inducer by covalently linking membrane protein‐targeting aptamer with mutant‐CXCL12 mimic peptide is developed. This selectively binds without activating CXCR4. AP‐CRTAC, which incorporates various forms from DNA, RNA, or even bispecific aptamers, has shown significant efficacy degrading one more proteins mutants on cell surface. Moreover, AP‐CRTAC constructed 2′ F‐pyrimidine‐modified RNA targeting EGFR effectively degrades mutations. Notably, enhances sensitivity L858R/T790M/C797S triple mutant lung cancer cells, are resistant current EGFR‐targeted therapies, third‐generation inhibitor osimertinib both vitro vivo settings. research introduces an engineered high specificity targeted surface proteins, while minimizing unwanted side effects.

Undruggable targets account for roughly 85% of human disease-related and represent a category therapeutic that are difficult to tackle with traditional methods, but their considerable clinical importance. These generally defined by planar functional interfaces the absence efficient ligand-binding pockets, making them unattainable conventional pharmaceutical strategies. The advent oligonucleotide-based proteolysis-targeting chimeras (PROTACs) has instilled renewed optimism in addressing these challenges. PROTACs facilitate targeted degradation undruggable entities, including transcription factors (TFs) RNA-binding proteins (RBPs), via proteasome-dependent mechanisms, thereby presenting novel approaches diseases linked targets. This review offers an in-depth examination recent progress integration PROTAC technology oligonucleotides target traditionally proteins, emphasizing design principles mechanisms action innovative PROTACs.

ABSTRACT Targeted protein degradation (TPD) is a rapidly emerging and potentially transformative therapeutic modality. However, the large majority of >600 known ubiquitin ligases have yet to be exploited as TPD effectors by proteolysis-targeting chimeras (PROTACs) or molecular glue degraders (MGDs). We report here chemical–genetic platform, Site-specific Ligand Incorporation-induced Proximity (SLIP), identify actionable (“PROTACable”) sites on any potential effector in intact cells. SLIP uses genetic code expansion (GCE) encode copper-free “click” ligation at specific site cells, enabling situ formation covalent PROTAC-effector conjugate against target interest (POI). Modification drives targeted protein, establishing these for TPD. Using SLIP, we systematically screened dozens across E3 E2 enzymes from diverse classes, identifying multiple novel PROTACable which are competent adds powerful approach proximity-induced pharmacology (PIP) toolbox, future ligand discovery fully enable TPD, other PIP modalities.

Traditional phenotypic drug discovery platforms have suffered from poor scalability and a lack of mechanistic understanding newly discovered probes. To address this, we created Endo- GeneScreen (EGS), high-throughput enabled screening platform that identifies bioactive small molecules capable regulating endogenous protein expression encoded by any preselected target gene within biologically appropriate context. As proof-of-concept, EGS successfully identified candidates up-regulate neuronal Syngap1, causes neurodevelopmental disorder when haploinsufficient. For example, SR-1815, previously unknown undescribed kinase inhibitor, alleviated major cellular consequences Syngap1 loss-of-function restoring normal SynGAP levels dampening hyperactivity haploinsufficient neurons. Moreover, demonstrate assays accelerate preclinical development facilitate mode-of-action deconvolution studies. Thus, first-in-class molecule probes promote biological precision therapeutic development.

Developing proteolysis-targeting chimeras (PROTACs) is well recognized through target protein degradation (TPD) toward promising therapeutics. While a variety of diseases are driven by aberrant ubiquitination and critical proteins with protective functions, stabilization (TPS) rather than TPD emerging as unique therapeutic modality. Deubiquitinase-targeting (DUBTACs), class heterobifunctional stabilizers consisting deubiquitinase (DUB) protein-of-interest (POI) targeting ligands conjugated linker, can rescue such from elimination. DUBTACs stabilize the levels POIs in DUB-dependent manner, removing ubiquitin polyubiquitylated degraded proteins. induce new interaction between POI DUB forming POI-DUBTAC-DUB ternary complex. Herein, benefits TPS approaches for human introduced, recent advances developing summarized. Relevant challenges, opportunities, future perspectives also discussed.
