Abstract: Imaging extracellular Cu2+ in vivo is of paramount interest due to its biological importance in both physiological and pathological states. Magnetic resonance imaging (MRI) is a powerful technique to do so. However, the development of efficient MRI contrast agents selective for Cu2+, particularly versus the more abundant Zn2+ ions, is highly challenging. We present here an innovative...[En savoir plus]
L’Institut de Chimie de Strasbourg a l’honneur de vous informer que le projet «Conception d’un ligand bioinspiré à 64/67Cu pour des applications théranostiques» déposé par Laurent RAIBAUT (équipe BCB, Bométaux et Chimie Biologique) dans le cadre de l’appel à projets Emergence@CNRSChimie 2025 a été retenu pour financement.

Abstract: The lipid cis-trans isomerase (Cti) is a periplasmic heme-c enzyme found in several bacteria including Pseudomonas aeruginosa, a pathogen known for causing nosocomial infections. This metalloenzyme catalyzes the cis-trans isomerization of unsaturated fatty acids in order to rapidly modulate membrane fluidity in response to stresses that impede bacterial growth. As a consequence,...[En savoir plus]
Abstract: The use of VIV and CuII spins to design weakly coupled and dissymmetric spin systems has been examined. Such systems were synthesized using porphyrin-based complexes, with external coordination sites allowing for the formation of dimers via a PdII linker ion. Continuous-wave (CW) Electron Paramagnetic Resonance (EPR) spectroscopy allowed the unequivocal magnetic characterization of the...[En savoir plus]
Abstract: Antimicrobial resistance (AMR) poses a serious threat to global health. The rapid emergence of resistance contrasts with the slow pace of antimicrobial development, emphasizing the urgent need for innovative drug discovery approaches. This study addresses a critical bottleneck in early drug development by introducing integral solvent-induced protein precipitation (iSPP) to rapidly...[En savoir plus]
Abstract: A totally controlled regiodivergent azidation of activated N-allenamides is presented. Using TMSN3/TBAF, β-azidation of N-allenamides occurs exclusively, yielding vinyl azides. Conversely, employing a TFA/TMSN3 mixture results solely in the formation of γ-azides. A subsequent formal Winstein rearrangement of the latter with DBU produces α-amido vinyl azides. Additionally,...[En savoir plus]
Tweet: The IFM team in collaboration with researchers at ENS Lyon and Institut Pasteur used advanced molecular simulations to investigate how cannabinoids bind to glycine receptors, an important pharmacological target for chronic pain. They discovered that tetrahydrocannabinol (THC) and anandamide (AEA) bind to more than one region of the receptor's transmembrane domain and characterized their...[En savoir plus]
