    Dissimilar-at-boron N-BODIPYs: from light-harvesting multichromophoric arrays to CPL-bright chiral-at-boron BODIPYs
    (Organic Chemistry Frontiers, 2023) Ray, César; Avellanal-Zaballa, Edurne; Muñoz Úbeda, Mónica; Colligan, Jessica; Moreno Jiménez, Florencio; Muller, Gilles ; López Montero, Iván; Bañuelos, Jorge; Lora Maroto, Beatriz; Moya Cerero, Santiago De La
    We report a workable and easy approach for the direct post-multifunctionalization of common BODIPYs (F-BODIPYs) with minimal interference to the starting photophysical behavior. It entails the easy transformation of an F-BODIPY into the corresponding N-BODIPY by using a dissimilarly-N,N′-disubstituted bis(sulfonamide), which is easily obtained from ethane-1,2-diamine. This approach is exemplified by the rapid synthesis of a selected battery of unprecedented dissimilar-at-boron N-BODIPYs, which are rationally designed to act as efficient multichromophoric arrays for light harvesting by excitation energy transfer, as specific bioprobes for fluorescent imaging, or as efficient chiroptical dyes exhibiting visible circular dichroism and circularly polarized luminescence. Noticeably, this approach has led to the synthesis of the first CPL-bright chiral-at-boron BODIPYs, a significant novelty in BODIPY chemistry and CPL emitters

    C60-based Multivalent Glycoporphyrins Inhibit SARS-CoV-2 Specific Interaction with the DC-SIGN Transmembrane Receptor
    (Small, 2023) Patino Alonso, Jennifer; Cabrera González, Justo Enrique; Merino Gracia, Javier; Nieta Ortiz, Gema; Katati, Jouma; Bezerra Da Cruz, Carlos; Mateos Gil, Pablo; Canales Mayordomo, María Ángeles; López Montero, Iván; Illescas Martínez, Beatriz María; Delgado Vázquez, Rafael; Martín León, Nazario
    Since WHO has declared the COVID-19 outbreak a global pandemic, nearly seven million deaths have been reported. This efficient spread of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) is facilitated by the ability of the spike glycoprotein to bind multiple cell membrane receptors. Although ACE2 is identified as the main receptor for SARS-CoV-2, other receptors could play a role in viral entry. Among others, C-type lectins such as DC-SIGN are identified as efficient trans-receptor for SARS-CoV-2 infection, so the use of glycomimetics to inhibit the infection through the DC-SIGN blockade is an encouraging approach. In this regard, multivalent nanostructures based on glycosylated [60]fullerenes linked to a central porphyrin scaffold have been designed and tested against DC-SIGN-mediated SARS-CoV-2 infection. First results show an outstanding inhibition of the trans-infection up to 90%. In addition, a deeper understanding of nanostructure-receptor binding is achieved through microscopy techniques, high-resolution NMR experiments, Quartz Crystal Microbalance experiments, and molecular dynamic simulations.
