The Chelate-To-Bridging Shift of Phosphane Dipalladacycles: Convenient Synthesis of Double A-Frame Tetranuclear Complexes
(Royal Society of Chemistry (Gran Bretaña), 2018-02-19)[Abstract] Palladacycles of the type [Pd2(Ph2PCH2PPh2-P,P)2(C,N:C,N)] (C,N:C,N = bis(N-2,3,4-trimethoxybenzylidene)-4,4′-sulfonyldianiline or -4,4′-oxydianiline) can undergo a spontaneous slow chelate-to-bridging diphosphane ... -
The Fish Pathogen Vibrio ordalii Under Iron Deprivation Produces the Siderophore Piscibactin
(MDPI, 2019-09-03)[Abstract] Vibrio ordalii is the causative agent of vibriosis, mainly in salmonid fishes, and its virulence mechanisms are still not completely understood. In previous works we demonstrated that V. ordalii possess several ... -
The Outer Membrane Protein FstC of Aeromonas salmonicida subsp. salmonicida Acts as Receptor for Amonabactin Siderophores and Displays a Wide Ligand Plasticity. Structure–Activity Relationships of Synthetic Amonabactin Analogues
(American Chemical Society, 2019-09-26)[Abstract] Amonabactins are a group of four related catecholate siderophores produced by several species of the genus Aeromonas, including A. hydrophila and the fish pathogen A. salmonicida subsp. salmonicida. Although the ... -
The Red Cage: Implementation of pH-Responsiveness Within a Macrobicyclic Pyridinium-Based Molecular Host
(Royal Society of Chemistry, 2021-11-09)[Abstract] We present herein the implementation of pH-responsiveness into a new polycationic macrobicyclic structure, namely what we have termed the “red cage”. The hydrolytically-stable cryptand-like compound has been ... -
The Siderophore Piscibactin Is a Relevant Virulence Factor for Vibrio anguillarum Favored at Low Temperatures
(Frontiers, 2018-08-02)[Abstract] Vibrio anguillarum causes vibriosis, a hemorrhagic septicaemia that affects many cultured marine fish species worldwide. Two catechol siderophores, vanchrobactin and anguibactin, were previously identified in ... -
@thermogramer: Thermal Imaging as a Tool for Science Communication and E-Learning in Social Media
(MDPI, 2022-03-07)[Abstract] The COVID-19 pandemic boosted the presence of thermal cameras in our society. These devices are becoming cheaper and smaller and can even be plugged in our smartphones. Therefore, soon enough everybody will have ... -
Thinking Outside the Blue Box: From Molecular to Supramolecular PH-Responsiveness
(Royal Society of Chemistry, 2019-10-23)[Abstract] We present herein the development of a new polycationic cyclophane: the “red box”, second in a series of hydrazone-based analogues of the well-known organic receptor cyclobis(paraquat-p-phenylene)cyclophane ... -
Thinking Outside the Blue Box: Induced Fit within a Unique Self-Assembled Polycationic Cyclophane
(ACS, 2019-02-07)[Abstract] We present herein the development of a new polycationic molecular receptor, inspired by the ubiquitous cyclobis(paraquat-p-phenylene)cyclophane (“blue box”). Our analogue, the “white box”, has been easily ... -
Transition-metal-free cross-coupling of indium organometallics with chromene and isochroman acetals mediated by BF3·OEt2
(American Chemical Society, 2016)[Abstract] A transition-metal-free coupling of triorganoindium reagents with benzopyranyl acetals mediated by a Lewis acid has been developed. The reaction of R3In with chromene and isochroman acetals in the presence of ... -
Triorganoindium reagents in Rh-catalyzed C–H activation/C–C cross-coupling reactions of 2-arylpyridines
(MDPI, 2018-06-29)[Abstract] The activation of C–H bonds through catalytic reactions using transition metals is an important challenge in organic chemistry in which the intermediates are related to those produced in the classical cross-coupling ... -
Uncovering the Cyanobacterial Chemical Diversity: The Search for Novel Anticancer Compounds
(MDPI, 2022-09-15)[Abstract] Cancer has a tremendous negative socio-economic impact on our society. Thus, the discovery of new and more effective anticancer drugs is of utmost importance. To address this societal challenge, the main goal ... -
Vermellogens and the Development of CB[8]-Based Supramolecular Switches Using pH-Responsive and Non-Toxic Viologen Analogues
(ACS, 2022-10-07)[Abstract] We present herein the “vermellogens”, a new class of pH-responsive viologen analogues, which replace the direct linking between para-substituted pyridinium moieties within those by a hydrazone functional group. ... -
Vibrio neptunius Produces Piscibactin and Amphibactin and Both Siderophores Contribute Significantly to Virulence for Clams
(Frontiers, 2021-10-25)[Abstract] Vibrio neptunius is an inhabitant of mollusc microbiota and an opportunistic pathogen causing disease outbreaks in marine bivalve mollusc species including oysters and clams. Virulence of mollusc pathogenic ...
