The therapeutic approach of targeted protein degradation (TPD) is gaining momentum due to its potentially superior effects compared with inhibition. Recent advancements in the biotech and pharmaceutical sectors have led development compounds that are currently human trials, some showing promising clinical results. However, use computational tools TPD still limited, as it has distinct characteristics traditional drug design methods. involves creating a ternary structure (protein-degrader-ligase) responsible for biological function, such ubiquitination subsequent proteasomal degradation, which depends on spatial orientation interest (POI) relative E2-loaded ubiquitin. Modeling this necessitates unique blend initially developed small molecules (e.g., docking) biologics protein-protein interaction modeling). Additionally, degrader molecules, particularly heterobifunctional degraders, generally larger than conventional molecule drugs, leading challenges determining drug-like properties like solubility permeability. Furthermore, catalytic nature makes occupancy-based modeling insufficient. consists multiple interconnected yet steps, POI binding, E3 ligase interactions, ubiquitination, along properties.

Targeting oncogenic mutant p53 represents an attractive strategy for cancer treatment due to the high frequency of gain-of-function mutations and ectopic expression in various types. Despite extensive efforts, absence a druggable active site small molecules has rendered these mutants therapeutically non-actionable. Here we develop selective effective proteolysis-targeting chimera (PROTAC) p53-R175H, common hotspot with dominant-negative activity. Using novel iterative molecular docking-guided post-SELEX (systematic evolution ligands by exponential enrichment) approach, rationally engineer high-performance DNA aptamer improved affinity specificity p53-R175H. Leveraging this resulting as binder PROTACs, successfully developed p53-R175H degrader, named dp53m. dp53m induces ubiquitin-proteasome-dependent degradation while sparing wildtype p53. Importantly, demonstrates significant antitumor efficacy p53-R175H-driven cells both vitro vivo, without toxicity. Moreover, significantly synergistically improves sensitivity cisplatin, commonly used chemotherapy drug. These findings provide evidence potential therapeutic value cancers.

Abstract Xeno‐nucleic acids (XNAs) are synthetic genetic polymers with improved biological stabilities and offer powerful molecular tools such as aptamers catalysts. However, XNA application has been hindered by a very limited repertoire of tool enzymes, particularly those that enable de novo synthesis. Here we report terminal deoxynucleotide transferase (TdT) catalyzes untemplated threose nucleic acid (TNA) synthesis at the 3’ terminus DNA oligonucleotide, resulting in DNA‐TNA chimera resistant to exonuclease digestion. Moreover, TdT‐catalyzed TNA extension supports one‐pot batch preparation biostable chimeric oligonucleotides, which can be used directly staple strands during self‐assembly origami nanostructures (DONs). Such TNA‐protected DONs show enhanced stability presence I, DNase I fetal bovine serum. This work not only expands available enzyme toolbox for manipulation, but also provides promising approach fabricate under physiological condition.
