Abstract

The antifungal activity of nitroxyl radicals-derivatives of 2,2,6,6-tetramethylpiperidine-1-oxyl with reactive substituents 4-isothiocyanato-, 4-isocyano-, and 4-isoselenocyanato- and of N-formyl-, N-thioformyl-, N-selenoformyl-derivatives of 2,2,6,6-tetramethylpiperidine was investigated. Those of the above compounds, which contain a sulfur or selenium atom are the most active against four fungus plant patogens: Botrytis cinerea, Fusarium culmorum, Phytophthora cactorum, Rhizoctonia solani. 4-Isoselenocyanato- 2,2,6,6-tetramethylpiperidine-1-oxyl proved to be the most active compound.

Antifungal mono- and dimeric nitrogenous bisabolene derivatives from a sponge in the order Bubarida from Futuna Islands

Maria Miguel-Gordo, Maggie M. Reddy, Pilar Sanchez, Jordan J. Buckley, Thomas A. Mackenzie, Laurence K. Jennings, Fernando Reyes, Kevin Calabro, Olivier P. Thomas

Summary: In this study, ten new nitrogenous bisabolene derivatives were isolated from a sponge collected from the Futuna Islands. These compounds include monomeric theonellin formamide analogues with unusual oxidised linear chains and the first isocyanide/formamide dimeric and cyclised bisabolenes. The structure elucidation involved various analysis methods, and a biosynthetic hypothesis was proposed. The antimicrobial and antitumoral activity of these compounds were evaluated, and the trans-dimer theonellin isocyanide was shown to exhibit potent and selective antifungal activity.

Recent Advances in the Synthesis of Isothiocyanates Using Elemental Sulfur

Andras Gy Nemeth, Peter Abranyi-Balogh

Summary: This review discusses the best practices for the synthesis of ITCs using elemental sulfur, including the in situ generation of thiocarbonyl surrogates and the reaction pathways of carbenes and amines to form isocyanides, which further react with sulfur to generate ITCs. Additionally, it reveals the existence of two previously overlooked and uninvestigated mechanistic pathways in the catalyst-free reaction of isocyanides and sulfur.

Asymmetric Organocatalytic Synthesis of aza-Spirocyclic Compounds from Isothiocyanates and Isocyanides

Adrian Lavios, Amparo Sanz-Marco, Carlos Vila, Gonzalo Blay, Jose R. Pedro

Summary: The spirocyclic motif is widely found in natural products, chiral ligands, and pharmacologically active compounds. The formal [3+2] cycloaddition reaction of isothiocyanates or isocyanides with cyclic compounds has been developed for the enantioselective synthesis of aza-spirocyclic compounds, with organocatalysis playing a key role in these reactions. The synthesis of spirooxindoles using this methodology has received particular attention, highlighting the importance of the structure of the dipolarophiles and the isothiocyanate and isocyanide dipoles.

Spatiotemporal imaging of redox status using in vivo dynamic nuclear polarization magnetic resonance imaging system for early monitoring of response to radiation treatment of tumor

Norikazu Koyasu, Fuminori Hyodo, Ryota Iwasaki, Hinako Eto, Abdelazim Elsayed Elhelaly, Hiroyuki Tomita, Shinichi Shoda, Masaki Takasu, Takashi Mori, Masaharu Murata, Akira Hara, Yoshifumi Noda, Hiroki Kato, Masayuki Matsuo

Summary: In this study, the usefulness of spatiotemporal redox status as an early imaging biomarker of tumor response after irradiation using in vivo DNP-MRI was demonstrated. The results showed that in vivo DNP-MRI/CmP allowed faster and earlier visualization of tumor redox status responses compared to the verification of morphological changes observed with 1.5 T MRI and cancer metabolism obtained by hyperpolarized C-13 pyruvate MRS. The early assessment of redox status alterations with in vivo DNP-MRI/CmP probe may provide efficient information regarding the effectiveness of subsequent radiation treatment.

An Enantiospecific Synthesis of Isoneoamphilectane Confirms Its Strained Tricyclic Structure

Natalie C. Dwulet, Zeinab Chahine, Karine G. Le Roch, Christopher D. Vanderwal

Summary: We have successfully synthesized the rare isocyanoterpene natural product isoneoamphilectane and its two unnatural diastereomers. Our initial hypothesis about a misassignment in the structure's relative configuration led us to target two less-strained stereoisomers, but they did not match the spectroscopic data of isoneoamphilectane. We then embarked on a challenging synthesis of the originally proposed strained structure, guided by computational analyses to control stereochemistry.

Conjugate-Driven Electron Density Delocalization of Piperidine Nitroxyl Radical for Stable Aqueous Zinc Hybrid Flow Batteries

Hao Fan, Bo Hu, Hongbin Li, Mahalingam Ravivarma, Yangyang Feng, Jiangxuan Song

Summary: We report a stable catholyte MIAcNH-TEMPO for aqueous zinc hybrid flow batteries (AZHFBs) with high stability and long-lasting capacity. By incorporating double-conjugate substituents, the electron density of TEMPO can be delocalized, resulting in the stabilization of its radical and oxoammonium forms and avoiding side reactions. The MIAcNH-TEMPO/Zn AZHFB exhibits excellent stability with a constant capacity retention of 99.95% per day over 16.7 days at high concentration catholyte and high current density.

Summary: Antibiotic resistance is a major threat to public health, with Gram-negative bacteria presenting unique challenges due to their low permeability and efflux pumps. Limited understanding of the chemical rules for overcoming these barriers hinders antibacterial drug discovery. Efforts to address this issue, such as screening compound libraries and using cheminformatic analysis, have led to the design of sulfamidoadenosines with diverse substituents, showing potential utility in accumulation in Escherichia coli.
