The plant Aster tataricus and its endophytic fungus Cyanodermella asteris are sources of a unique class of halogenated pentapeptides called astins. In addition, the fungus Talaromyces islandicus produces the astin-related class of pentapeptides, cyclochlorotines. Through molecular networking and mass spectrometry fragmentation data, we uncover a huge chemical diversity among the astin and cyclochlorotine pool of pentapeptides, which also reflects the genetic homology of both nonribosomal peptide synthetase (NRPS) systems and deepens our understanding of astin biosynthesis and enzymology.

This study demonstrates that dilute Mn(II) (∼0.02 mol%) doped into the Zn(II)-MOF [CH6N3][Zn(HCOO)3] act as high-spin (S = 5/2) spin qubits, achieving microsecond phase memory times above 50 K—the first report for Mn(II)-based systems. Robust hydrogen-bonding networks suppress relaxation and stabilize the lattice, extending T2. Resonance between MS = ±1/2 and quantization axis tilting reveal tunable spin dynamics, highlighting MOFs as promising platforms for high-spin molecular qubits.

We reveal that the surface properties of the substrate play a crucial role in determining the surface composition and optoelectronic properties of the perovskite films. By optimizing the HTL, we achieved 17.5% efficiency for semitransparent perovskite solar module via all vacuum deposition processes.

All-heteroatom sulfurdiimidoyl structures are highly versatile structures but hardly any synthetic methods exist to make them. Here, we present a general route to aminosulfurdiimidoyl fluorides (ASDFs) from amino difluorothiazynes. Exploiting the ambiphilic nature of fluorothiazynes, ASDFs were prepared via sequential alkylation and imination, and these were engageable as versatile SuFEx electrophiles for advanced sulfur(VI) chemistry.

The design and synthesis of a linear tetradentate NCCN ligand incorporating two 1,2,3-triazolin-5-ylidene mesoionic carbene donors, and its application to asymmetric iron catalysis is reported. This work represents the first example of an iron complex derived from a cis-α-coordinating tetradentate NCCN ligand, and notably, the first chiral iron catalyst derived from an achiral tetradentate ligand.

The pentaPod (P5) concept unites tridentate and tripodal fragments to form molybdenum and tungsten catalytic Chatt-type complexes for N2-to-NH3 reduction. Two pentaPod ligands, P5Me and P5Pln, are available with either two dimethylphosphine or phospholano (Pln) groups. The complexes enable the investigation of reactivity differences in N2 reduction and, in particular, allow investigation of the basicity differences between molybdenum and tungsten complexes.

The endogenous cancer metabolite acrolein triggers a catalyst-free cyclodimerization cascade. This intracellular polymerization uses a specifically engineered monomer containing a tetraphenylethylene (TPE) unit, which generates a strong aggregation-induced emission signal. This strategy enables “turn-on” fluorescence, allowing for selective and precise imaging of malignant cells in human breast cancer tissue.

Drying conditions drive reactions between amino acids and keto acids, generating a wide variety of small, reactive species, highlighting for the first time the potential significance of drying reactions in proto-metabolism on early Earth. Condensation-dehydration reactions are critical to both metabolism and polymerization in extant biology, and their co-evolution driven by dried environments on early Earth may have played a pivotal role on the path to first life.

Pd complexes with electronically modified NHCs (NHC = N-heterocyclic carbene) were analyzed in the Buchwald-Hartwig Amination under both strongly and weakly basic conditions. Investigations into the steric and electronic properties of the ligands are detailed. Highly active precatalysts are reported bound even when using the non-nucleophilic weak base NaBHT.

Beer flavor is influenced by 1,2-dicarbonyl compounds. Their reaction with ethanol is shown for the first time in this work. After preparation of a standard substance, quantitation of the 3-deoxy-4-ethoxyhexosones by HPLC-MS/MS revealed concentrations of up to 1.5 mg/L in beer and a neoformation during storage.

Via in silico docking of pyrichalasin H on G- and F-actin, the C21-OAc moiety is identified as a modifiable site tolerated for actin binding. Fluorescent [11]cytochalasan probes from pyrichalasin H and epoxycytochalasin C are obtained by selective C21-OAc hydrolysis and acylation. The conjugates retain actin binding and bioactivity, establishing C21-OAc as a versatile handle for functionalization.

Peptides are developed for reversible binding to sugar-rich structures (glycans) in cell-derived extracellular matrix models using boronic acid chemistry. By attaching a carboxy-phenyl-boronic acid group to the N-terminus of peptides, a modified myostatin inhibitor is synthesized that retaines biological activity comparable to standard inhibitors. This modification may improve how these peptides interact with tissues, offering potential benefits for drug delivery in future pharmacological studies.

Gold nanoparticles (AuNPs) have attracted attention due to several advantages, such as optical properties and easy functionalization. In particular, aggregation of AuNPs induced by target molecules can be monitored via optical or electrochemical methods for molecular sensing. This review aims to highlight molecular sensing strategies focusing on aggregation mechanisms of AuNPs and detection methods, including one using dark-field microscopy.

A modular synthetic approach enables the preparation of azulene-fused heterocycles via nucleophilic aromatic substitution followed by intramolecular cyclization of alkynyl fluoroazulenes. The method allows the incorporation of various heteroatoms (N, O, S, Se, and Te), leading to structurally diverse heteroannulated azulenes. The resulting compounds exhibit distinct electronic features and acid-responsive behavior.

A concise protocol is presented that converts pyridines into anilines by externalizing the original pyridine nitrogen at either the "ipso" or "ortho" position, which results in para or meta-primary aniline products. A key carbene-insertion step precedes nitrogen migration, preserving both ring size and overall structure.

A thermodynamics-controlled epitaxial growth strategy enables the precise coating of Cs4PbBr6 onto NaYF4:Yb,Tm UCNPs, achieving structural evolution from core-shell to UCNP-in-LHP solids heterostructures. These high-quality heterostructures exhibit widely tunable upconversion emission across the entire visible spectrum—from blue to green to red—governed by a dynamic energy recycling mechanism between Tm3+ and the perovskite layer.
