Lysosome‐Targeted Squaramide Anion Transporters

Chemistry – A European Journal, EarlyView.
Lysosome‐targeted squaramide anion transporters elicit different biological effects depending on the targeting group employed. ABSTRACT Targeting anion transporters to specific organelles has previously been shown to be an effective strategy to enhance their cytotoxicities against cancerous cell lines.

Structural and variable-temperature NMR studies of 9-diisopropylphosphanylanthracenes and 9,10-bis(diisopropylphosphanyl)anthracenes and their oxidation products

, 2008
The diisopropylphosphanyl-substituted anthracenes i-Pr(2)P(C(14)H(9)) (1a), i-Pr(2)P(C(14)H(8))Br (2a), and (i-Pr(2)P)(2)(C(14)H(8)) (3a) and some of their oxidation products were prepared from 9-bromoanthracene and 9,10-dibromoanthracene, respectively ...

Synthesis and Structure of an S‐Shaped Double Expanded Helicene With Seven Fused Anthracene Units

Chemistry – A European Journal, EarlyView.
The anthracene‐fused aromatic compound was synthesized by four‐fold cycloisomerization of the corresponding alkyne precursor. X‐ray crystallographic analysis revealed that this compound had a double helical structure of Ci symmetry, in which the terminal and central anthracene units were triply stacked.

From Data to Dimers: Engineering Acene Derivatives for Photovoltaic Singlet Fission

Chemistry – A European Journal, EarlyView.
Excited‐state energies of acene derivatives are predicted using a ChemBERTa‐based regression model and subsequently used to screen candidates for photovoltaic singlet fission using dimer–monomer benchmarked energetic criteria. Promising candidates are predominantly 5‐ and 6‐fused heteroacenes, which offer enhanced stability and higher triplet energies ...

Synthesis and Structure of Unsymmetrical Anthracenyl-Isoxazole Antitumor Agents Via the Diastereoselective Bromination of 3-(9′-Anthryl)-Isoxazole Esters

Crystals
In pursuit of unsymmetrical precursors for the novel series of anthracenyl-isoxazole amide (AIM) antitumor agents, a series of substituted anthracenes were subjected to bromination and re-aromatization in our study, during which we solved four single ...

Synthesis and Structures of Novel Chiral Cyclic Hypervalent Iodine(III) Reagents for Metal‐Free Ligand‐Transfer Reactions

Chemistry – A European Journal, EarlyView.
Several new chiral cyclic hypervalent iodine(III) reagents have been synthesized and characterized. Carbon‐based ligands were successfully installed onto the hypervalent iodine centers, giving thus access to novel chiral cyano‐, trifluoromethyl‐ or alkynyl‐bearing λ3‐iodanes.

Assessment of antimicrobial and anti-biofilm activities of lemongrass and bay leaf extracts on microorganisms from fermented cereal-based porridges in northern Benin

Scientific African
Lemongrass (Cymbopogon citratus) and bay leaf (Laurus nobilis) are condiments in food processing. This study aimed to assess the antimicrobial and anti-biofilm activities of lemongrass and bay leaf extract on the microorganisms isolated from cereal-based

Cyclization of a 1,8‐Diphenylanthracene by Scholl Reactions to Form Five‐ and Seven‐Membered Ring Embedded Polycyclic Aromatic Hydrocarbons

Chemistry – A European Journal, EarlyView.
Reactions of 10‐mesityl‐1,8‐diphenylanthracene with DDQ/TfOH produced three products via sequential formation of a five‐ or seven‐membered ring. Unexpectedly, the triply cyclized product with a rubicene substructure was formed through cyclization involving 1,2‐methyl shift.

Behavior of the heterogeneous electron-transfer rate constants of arenes and substituted anthracenes in room-temperature ionic liquids

, 2008
We report the anodic oxidation of several arenes and anthracenes within room-temperature ionic liquids (RTILs). In particular, the heterogeneous electron-transfer rates (k(0)) for substituted anthracenes and arenes are also investigated in 1-ethyl-3 ...

Halogenated Tryptophans Improve Integrin αVβ6 Affinity of Cyclic RGD Peptides and Provide Handles for Late‐Stage Derivatization

Chemistry – A European Journal, EarlyView.
Lighting up αVβ6: Halotryptophan engineering converts an RGD scaffold into a modular αVβ6 ligand platform, enabling picomolar affinity and late‐stage functionalization. The resulting probes combine high selectivity with fluorescence for FACS and tumor imaging.
