Summary: Early screening of biomarkers is important for the therapy and prognosis of cancers. MiRNAs encapsulated in tumor-derived exosomes have emerged as biomarkers for early cancer diagnosis. However, traditional methods have limitations that restrict their wide applications. In this study, a convenient electrochemical approach based on DNA triangular pyramid frustum (TPF) and strand displacement amplification was developed for quantification of exosomal miRNA. The biosensor showed excellent analytical performances and successfully analyzed exosomal miRNAs from cells and clinical serum samples.

Summary: This paper analytically and numerically studies the large deflection of the foam-filled triangular tube (FFTT) under transverse loading. A yield criterion is established based on the strengths of the foam and the tube. A theoretical model is developed for the large deflection of the clamped triangular tube filled with foam under transverse loading. Numerical simulations using ABAQUS/Standard software are conducted and compared with analytical results. The effects of foam strength, tube thickness, and punch width on the load-bearing capacity and energy absorption of the clamped FFTT are discussed.

Summary: The first total syntheses of tricyclic mutanobactins A and B, lipopeptides incorporating a thiazepanone, isolated from Streptococcus mutans, a member of the human oral microbiome, were reported. These natural products were rapidly delivered through a cascade of cyclization reactions using a solid-phase peptide synthesis (SPPS) based route. This versatile process was also used for a streamlined synthesis of mutanobactin D. Additionally, an independent synthesis of a truncated mutanobactin A analog, utilizing a novel thiazepanone amino acid building block, was provided.

Summary: A new type of coordination-driven cuboctahedron cage was presented to study the fluorescent behavior of quantitatively confined aggregation-induced emission (AIE) molecules in a giant cavity. The cage, with 12 AIE molecules anchored endohedrally linked with different-length alkyl chains, exhibited strong fluorescence in highly diluted conditions. The fluorescence quantum yield could be altered by prolonging the length of alkyl chains. This study has great potential applications in biology mimic and fluorescent microscopes utilizing confined or isolated fluorescent methods.

Summary: In this study, a decametric metal-organic cage, pentagonal prism Mn20LC10, was developed based on Tpy-Mn(II)-Tpy connectivity, with Mn(II) serving as a linker to provide good photosensitivity. This metal-organic cage exhibited enhanced 1O2 production, fast conversion time, recyclability, and substrate versatility in the photooxidation of benzaldehyde due to improved intersystem crossing ability. Remarkably, the abundant active sites of Mn20LC10 enabled its photooxidation under solvent-free and daylight conditions. This work offers potential approaches for the development of inexpensive, green, and low-cost photosensitizer systems.

Summary: We report a terpyridine-based metallo-cage that can undergo controlled hierarchical self-assembly of superstructures in response to different halide ions. By adding Cl-/Br- or I-, drastically different hierarchical superstructures with highly-tight hexagonal packing or graphite-like packing arrangements, respectively, have been achieved. These unusual halide-ion-triggered hierarchical structural changes provide new insights into the mechanism of supramolecular aggregation and crystal growth.

Summary: In the field of metallo-supramolecular assemblies, supramolecular macrocycles with guest recognition and catalytic properties have attracted attention. This study presents a novel strategy for constructing giant hollow macrocyclic structures using a bi-directional geometric constraint strategy. By designing two terpyridine-based tetratopic organic ligands with different angles, the mutual interaction between the ligands promotes the formation of giant hollow macrocyclic supramolecular architectures. The self-assembly mechanism and hierarchical self-assembly of the giant supramolecular macrocycles are characterized by NMR, ESI-MS, and TEM experiments.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
