There is a growing need for biocompatible click reactions in order to prepare multifunctional conjugates, which are valuable molecules for innovative biomedical applications. In this context, we review the recent advances in the implementation of oxime ligation for the synthesis of multivalent or multicomponent systems. The value of these products is… (More)
Herein, we present a study of the pharmacokinetics and biodistribution of a butadiyne-linked conjugated porphyrin dimer (Oxdime) designed to have high near-infrared (NIR) 2-photon absorption cross-section for photodynamic therapy (PDT). Changes in biodistribution over time were monitored in mice carrying B16-F10 melanoma xenografts, following intravenous… (More)
Maintaining high transcriptional fidelity is essential to life. For all eukaryotic organisms, RNA polymerase II (Pol II) is responsible for messenger RNA synthesis from the DNA template. Three key checkpoint steps are important in controlling Pol II transcriptional fidelity: nucleotide selection and incorporation, RNA transcript extension, and proofreading.… (More)
Invited for the cover of this issue are Jean-Yves Winum and co-workers at University of Montpellier (France) and University of Florence (Italy). The image depicts the multivalency approach applied to zinc metalloenzyme carbonic anhydrases. Read the full text of the article at 10.1002/chem.201501037.
Molecules having different accessible shape states, which can be addressed in an effector-controlled manner, may be termed morphological switches. A dynamic covalent system can undergo adaptation to each state of a two-state morphological switch by generation of an optimal constitution through component selection. We have studied such a component selection… (More)
Self-sorting dynamic library: The effector-induced modulation of the shape and constitution of the members of a constitutional dynamic network (see scheme) allows for the regulation of the interconnected constituents and for the control of an emergent function, here the generation of an optical output which originates from a charge-transfer interaction.
The design of smart nonviral vectors for gene delivery is of prime importance for the successful implementation of gene therapies. In particular, degradable analogues of macromolecules represent promising targets as they would combine the multivalent presentation of multiple binding units that is necessary for achieving effective complexation of therapeutic… (More)
Bisfunctionalized guanidinium compounds displaying aromatic side groups of varying size are shown to self-assemble in aqueous solution with single-stranded DNA through phosphodiester backbone recognition. Competition experiments indicate the importance of π-stacking interactions in the stabilization of these DNA-templated supramolecular self-assemblies.
Artificial multivalent recognition systems offer promising perspectives for developing synthetic compounds capable of interacting effectively and selectively with biomolecules in aqueous medium. The identification of multi-point binding ligands requires screening of a large number of complex structures, with different spacers, different ligands, and varying… (More)
