Ylide‐Functionalization via Metalated Ylides: Synthesis and Structural Properties
ChemistryOpen, 2019 The α‐metallated ylides [Ph3P−C−Z]−M+ (with Z=SO2Tol or CN and M=Na or K) were used as versatile nucleophiles for the facile access to ylide‐substituted compounds. Halogenations, alkylations, carbonylations and functionalization reactions with main group

NMR-Assisted Structure Elucidation of an Anticancer Steroid-β-Enaminone Derivative
Magnetochemistry, 2017 The fortuitous modification of a quinoline-proline-piperazine side chain linked to a steroid in the presence of lithium (trimethylsilyl) acetylide has generated an unknown product that is more active than its precursor.

Molecular Oncology, EarlyView.AZD9291 has shown promise in targeted cancer therapy but is limited by resistance. In this study, we employed metabolic labeling and LC–MS/MS to profile time‐resolved nascent protein perturbations, allowing dynamic tracking of drug‐responsive proteins. We demonstrated that increased NNMT expression is associated with drug resistance, highlighting NNMT ...

A new member of the fusaricidin family – structure elucidation and synthesis of fusaricidin E
Beilstein Journal of Organic Chemistry, 2017 Two hitherto unknown fusaricidins were obtained from fermentation broths of three Paenibacillus strains. After structure elucidation based on tandem mass spectrometry and NMR spectroscopy, fusaricidin E was synthesized to confirm the structure and the ...

Separation and Structural Elucidation of Xenobiotics in the Pico- to Nanogram Scale
CHIMIA, 1999 Structural elucidation and quantification of complex mixtures of organic compounds is a real challenge when i) the substance amount approaches the pg to ng range, ii) a lot of closely related structures are present, and iii) when no special structure ...

Molecular Oncology, EarlyView.Following high dose rate brachytherapy (HDR‐BT) for hepatocellular carcinoma (HCC), patients were classified as responders and nonresponders. Post‐therapy serum induced increased BrdU incorporation and Cyclin E expression of Huh7 and HepG2 cells in nonresponders, but decreased levels in responders.

Molecular Oncology, EarlyView.Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.
