Inverse Design of Singlet‐Fission Materials with Uncertainty‐Controlled Genetic Optimization

open access: yesAngewandte Chemie, Volume 137, Issue 3, January 15, 2025.
We uncover candidates for singlet fission using a machine learning‐driven uncertainty‐controlled genetic algorithm (ucGA), which is run either in an exploitative or explorative manner. Leveraging a fragment database (reFORMED) derived from crystal structure data, we propose a class of heteroatom‐rich mesoionic compounds as acceptors for charge‐transfer

NO donors: Focus on furoxan derivatives [PDF]

open access: yesPure and Applied Chemistry, 2004
Abstract The article focuses attention on furoxan derivatives (1,2,5 oxadiazole 2-oxides) as NO donors. Possible mechanisms for NO release from these products in physiological solution and in segments of rabbit femoral artery are briefly considered.

Design and Synthesis of Novel Purine Analogues as Potential IL‐1β Inhibitors Targeting Vascular Inflammation

open access: yesChemistry &Biodiversity, Volume 23, Issue 1, January 2026.
Initial screening of the synthesized compounds revealed that compounds MK175 and MK169 inhibited LPS‐induced IL‐1β release in human aortic smooth muscle cells. ABSTRACT Proinflammatory cytokine interleukin (IL)‐1β is a key mediator of the inflammatory response in atherosclerosis.

Dimerizations of Nitrile Oxides to Furoxans Are Stepwise via Dinitrosoalkene Diradicals:  A Density Functional Theory Study

open access: yes, 2016
Density functional theory calculations at the B3LYP/6-31G* level on the dimerization reactions of acetonitrile oxide and para-chlorobenzonitrile oxide to form furoxans indicate that these processes are stepwise involving dinitrosoalkene intermediates ...

Synthesis of Alpha‐Acyloxy‐(1,2,5‐Oxadiazole‐2‐Oxide) Carboxamides via Passerini Multicomponent Reaction. Evaluation of Nitric Oxide‐Releasing and Anti‐Proliferative Properties

open access: yesJournal of Heterocyclic Chemistry, Volume 62, Issue 10, Page 1285-1292, October 2025.
The Passerini multicomponent reaction was used to synthesize α‐acyloxy‐(1,2,5‐oxadiazole‐2‐oxide)carboxamides in good to excellent yields (67‐97%) under microwave heating. All compounds were able to release NO in solution, within the concentration range of 0.8–7.4 μM. Antiproliferative activity was investigated against LNCaP, MCF‐7, and SK‐MEL‐28 tumor

Synthesis of Furoxans and Isoxazoles via Divergent [2 + 1 + 1 + 1] Annulations of Sulfoxonium Ylides and tBuONO

open access: yes, 2019
We have presented a simple and new method for the divergent assembly of furoxans and isoxazoles in which the [2 + 1 + 1 + 1] annulation reaction of sulfoxonium ylides is reported for the first time.

The CF3 Group as a Synthon of the CF+ Unit in Palladium Chemistry

open access: yesAngewandte Chemie, Volume 136, Issue 26, June 21, 2024.
Pulling fluorine off: The unusually high activity of the C−F bond found in the homoleptic trifluoromethyl‐palladium(II) complex [Pd(CF3)4]2− is correlated to the very low fluoride‐ion affinity of the conjugate difluorocarbene complex [(CF3)3Pd(CF2)]−, which is experimentally detected.

A novel hybrid aspirin-NO-releasing compound inhibits TNFalpha release from LPS-activated human monocytes and macrophages

open access: yesJournal of Inflammation, 2008
Background The cytoprotective nature of nitric oxide (NO) led to development of NO-aspirins in the hope of overcoming the gastric side-effects of aspirin.

New Synthetic Route to 4,6‐Diamino‐5,7‐dinitro‐benzo‐furazan, Important Decomposition Product of 1,3,5‐Triamino‐2,4,6‐trinitrobenzene

open access: yesPropellants, Explosives, Pyrotechnics, Volume 50, Issue 7, Page 7-10, July 2025.
The well‐known insensitive high explosive, 1,3,5‐triamino‐2,4,6‐trinitrobenzene (TATB), decomposes in abnormal environments, such as heat and impact, to produce, in part, 4,6‐diamino‐5,7‐dinitro‐benzo‐furazan (F1). This reaction has been documented for almost 50 years, but the structure of F1 has remained elusive.
