Proteolysis-targeting chimeras (PROTACs) are an emerging therapeutic modality that show promise to open a target space not accessible conventional small molecules via degradation-based mechanism. PROTAC degraders, due their bifunctional nature, which is categorized as ‘beyond the Rule of Five’, have gained attention distinctive approach for oral administration in clinical settings. However, development PROTACs with adequate bioavailability remains significant hurdle, largely large size and less than ideal physical chemical properties. This review encapsulates latest advancements orally delivered entered evaluation well developments highlighted recent scholarly articles. The insights methodologies elaborated upon this could be instrumental supporting discovery refinement novel degraders aimed at treatment various human cancers.

Androgen receptor (AR) has been extensively established as a potential therapeutic target for nearly all stages of prostate cancer (PCa). However, acquired resistance to AR-targeted drugs inevitably develops and severely limits their clinical efficacy. Particularly, there currently exists no efficient treatment patients expressing the constitutively active AR splice variants, such AR-V7. Herein, we report structure–activity relationship studies 55 N-heterocycle-substituted hydantoins, which identified structural motifs required AR/AR-V7 degradation. Among them, most potent compound 27c exhibited selective degradation over other hormone receptors excellent antiproliferative activities in LNCaP 22RV1 cells. RNA sequence analysis confirmed that effectively suppressed transcriptional activity signaling pathway. Importantly, demonstrated antitumor efficacy an enzalutamide-resistant xenograft model. These results highlight promising dual degrader overcoming drug advanced PCa variants.

ABSTRACT Proteolysis-targeting chimeras (PROTACs), a pioneering class of heterobifunctional ligands, have emerged as transformative tools in combating cancer and immune-related diseases due to their ability target previously undruggable proteins overcome drug resistance. Accurate assessment the degradation potential PROTACs is essential for advancing therapeutic applications. However, development robust predictive models hindered by scarcity large-scale datasets domain-specific tools, well underutilization existing unlabeled data. To address these challenges, we developed an innovative method called AiPROTAC predict capacity PROTACs. In particular, integrates graph augmentation, message-passing enhanced encoders cross-attention mechanisms within contrastive learning framework. Moreover, leverages curated specialized dataset combined with PROTAC-DB enhance prediction accuracy. Experimental results across two six evaluation metrics demonstrate that consistently outperforms state-of-the-art models. Further case studies underline its superior sensitivity reliability. Notably, facilitated design novel androgen receptor (AR) degrader, PROTAC GT19, which achieved vitro compared Bavdegalutamide (ARV-110). This advancement highlights our AiPROTAC’s accelerate PROTAC-based optimization.

PROTACs that degrade target proteins to treat diseases represent a highly promising strategy in drug design. However, the degradation of nondisease tissues may lead systemic toxicity. Herein, capitalizing on characteristic overexpression PSMA prostate cancer, we devised PSMA-guided PROTACs-specific targeting cancer. By conjugation AR degraders and BET separately with ligands via cleavable linkers, two classes were obtained. In vitro experiments demonstrated selectively degraded PSMA-overexpressing cancer cells without affecting other cells. vivo studies revealed compared conventional PROTACs, enhanced exposure prolonged half-life consequently achieved stronger more sustained therapeutic effects. This work provides novel avenue for disease tissue-specific PROTAC research, holding significant implications targeted therapy

Cell-membrane proteins are critical mediators of signal transduction, playing essential roles in disease occurrence and progression. The emerging LYTACs (Lysosome-targeting chimeras) technology combines drug-targeting strategies with lysosomal degradation, providing a novel approach to drug development offering new possibilities for therapy. However, the clinical applicability current LYTAC degraders is limited by variable expression lysosome-targeting receptors (LTRs) tissues. To overcome this limitation, we herein hijacked YXXØ sorting that derived from lysosome-associated membrane protein 2a (LAMP-2a) develop aptamer platform (SApt), which exhibits high specificity targeting inducing efficient degradation. SApts were synthesized conjugating peptide aptamer’s terminus through click reaction. Our study demonstrated efficiently degrade disease-associated proteins, such as PTK7, Met, NCL, based on inherent signals rather than specific LTR. potent antitumor efficacy was further confirmed xenograft tumor model, where vivo degradation PTK7 observed. Collectively, our work provides insights into simple universal potential translational value treatment.
