Summary: In this study, cyclodextrin (CD) as a bio-based polyhydroxy compound was used to construct an intumescent flame-retardant system with ammonium polyphosphate (APP) for flammable and fire-hazardous silicone rubber (SR). The poor compatibility and water resistance of SR composites were improved by introducing a bio-inspired hydrophobic structure for CD and APP. The results showed that the flame retardancy of SR composites reached a limiting oxygen index (LOI) of 30.7% and UL-94 V-0 rating with 40 phr total fillers loadings. Water soaking tests confirmed the maintained flame retardancy of SR composites under hot aqueous medium. The improved flame retardancy can be attributed to the good thermal stability and char-forming ability of the modified APP and CD, as well as the gas phase dilution and condensed phase barrier mechanisms.

Summary: Bio-inspired design (BID) approaches have provided innovative design proposals, but also led to an explosion of alternatives. Choosing personalized recommendations has become more difficult, and engineer may prefer fewer goals. However, the diversity and feasibility of BID often contradict each other. To address these issues, this study proposes a interdisciplinary approach using BERT and Pareto dominance theory for biological strategy decision (BPBSD) in BID. Experimental results demonstrate the effectiveness of BPBSD in balancing diversity and feasibility in BID, providing practical guidance for BID.

Summary: Liquid-liquid phase separation (LLPS) is a complex physicochemical phenomenon mediated by multivalent transient weak interactions among macromolecules like polymers, proteins, and nucleic acids. It has implications in cellular physiology and disease conditions like cancer and neurodegenerative disorders. Limited chemical tools exist to modulate protein LLPS, and the development of small-molecule modulators (SMMs) could provide therapeutic potential for neurodegenerative disorders. Rationally designed cyclic dipeptide (CDP)-based SMMs have been shown to effectively inhibit and dissolve Zn-mediated tau LLPS condensates, as well as inhibit tau condensate-to-fibril transition, establishing a novel platform for the development of therapeutics for neurodegenerative disorders.

Summary: Efficient delivery of bioactive ingredients into cells remains a challenge, and cell-penetrating peptides (CPPs) have emerged as promising delivery vehicles. In this study, novel CPPs derived from the flexible and disordered tail extensions of DNA-binding Ku proteins were developed. The lead CPP, Ku-P4, demonstrated high internalization efficacy and biocompatibility. The presence of proline residue was crucial for maintaining the intrinsically disordered state and biocompatibility. Biophysical and DNA binding studies revealed that Ku-P4 efficiently condensed DNA into positively charged polyplexes, which were then able to penetrate the cell membrane and deliver the plasmid DNA inside the cell. These findings suggest that these novel CPPs have the potential to enhance the cellular uptake and therapeutic efficacy of peptide-drug or gene conjugates.

Summary: The differential structures of designer peptidomimetics derived from amyloid beta (Aβ14-23) peptide were manipulated to stabilize distinct Cu oxidation states, which catalyzed different chemical reactions effectively. By incorporating cyclic dipeptide (CDP) and pyrene (Py) units, the Cu-chelation and self-assembly properties of Aβ14-23 peptide were tuned to form nanosheets and micelle-like core-shell structures. These structures demonstrated the ability to stabilize Cu-II and Cu-I states separately and catalyze tandem oxidative-hydrolysis and alkyne-azide cycloaddition reactions.
