TAR DNA binding protein 43 (TDP-43) is a key target in amyotrophic lateral sclerosis (ALS) treatment. Here, based on hydrophobic tagging strategy, we designed and synthesized a series of single or double hydrophobic tags conjugated peptides D1-D8. Among them, it was found that D4 displayed strongest ability to induce TDP-43 degradation in cells. D4 could reduce TDP-43 induced cytotoxicity. Besides, D4 could reduce TDP-43 levels in a transgenic drosophila model.

Activating the pyroptosis pathway of tumor cells by photodynamic therapy (PDT) for immunogenic cell death (ICD) is considered a valid strategy in pursuit of antitumor immunotherapy, but it remains a huge challenge due to the lack of reliable design guidelines. Moreover, it is often overlooked that conventional PDT can exacerbate the development of tumor immunosuppressive microenvironment, which is apparently unfavorable to clinical immunotherapy. The endoplasmic reticulum's (ER) pivotal role in cellular homeostasis and its emerging link to pyroptosis have galvanized interest in ER-centric imaging and therapeutics.

Xanthine nucleosides play a significant role in the expansion of the four-letter genetic code. Herein, 7-functionalized 8-aza-7-deazaxanthine ribo- and 2'-deoxyribonucleosides are described. 2-Amino-6-alkoxy nucleosides were converted to halogenated 8-aza-7-deazaxanthine nucleosides by deamination followed by hydroxy/alkoxy substitution.

The relentless pursuit of innovative hydrophobic tags remains a formidable challenge within the realm of targeted protein degradation. Herein, we have uncovered the remarkable potential of D-ring-contracted artemisinin as a potent hydrophobic tag that demonstrates exceptional degradation efficiency. We have crafted a series of conjugates by fusing D-ring-contracted artemisinin with raloxifene, and among these, has emerged as a promising candidate for degrading estrogen receptor α (ERα).

Glutathione-S-transferase, such as that of Schistosoma japonicum (sjGST) belongs to the most widely utilized fusion tags in the recombinant protein technology. The E26H mutation of sjGST has already been found to remarkably improve its ability for binding divalent ions, enabling its purification with immobilized metal affinity chromatography (IMAC). Nevertheless, most characteristics of this mutant remained unexplored to date.

Ribonucleoprotein (RNP)-based CRISPR/Cas9 genome editing holds great potential for the treatment of choroidal neovascularization (CNV), which however, is challenged by the lack of efficient cytosolic protein delivery tools. Herein, reversibly-phosphorylated pro-proteins (P-proteins) with conjugated adenosine triphosphate (ATP) tags are engineered and coupled with a membrane-penetrating, guanidine-enriched, α-helical polypeptide (GP) to mediate robust and universal cytosolic delivery. GP forms salt-stable nanocomplexes (NCs) with P-proteins via electrostatic interaction and salt bridging, and the helix-assisted, strong membrane activities of GP enabled efficient cellular internalization and endolysosomal escape of NCs.
