Reversible Control of DNA Binding with Cucurbit[8]uril-Induced Supramolecular 4,4′-Bipyridinium–Peptide Dimers
(American Chemical Society, 2021-03-08)[Abstract] Many cellular processes in living organisms are regulated by complex regulatory networks, built from noncovalent interactions between relatively few proteins that perform their functions by switching between ... -
RuII(p-cymene) Compounds as Effective and Selective Anticancer Candidates with No Toxicity in Vivo
(American Chemical Society (ACS), 2018-10-19)[Abstract] Ruthenium(II) complexes are currently considered a viable alternative to the widely used platinum complexes as efficient anticancer agents. We herein present the synthesis and characterization of half-sandwich ... -
Selective Detection of Aeromonas Spp. By a Fluorescent Probe Based on the Siderophore Amonabactin
(Elsevier, 2022-02-03)[Abstract] Amonabactins, the siderophores produced by some pathogenic bacteria belonging to Aeromonas genus, can be used for the preparation of conjugates to be imported into the cell using their specific transport machinery. ... -
Self-Assembled Peptide–Inorganic Nanoparticle Superstructures: From Component Design to Applications
(Royal Society of Chemistry, 2020-06-04)[Abstract] Peptides have become excellent platforms for the design of peptide–nanoparticle hybrid superstructures, owing to their self-assembly and binding/recognition capabilities. Morover, peptide sequences can be encoded ... -
Sequential In-catalyzed intramolecular hydroarylation and Pd-catalyzed cross-coupling reactions using bromopropargyl aryl ethers and amines
(Royal Society of Chemistry, 2017)[Abstract] A sequential one-pot indium-catalyzed intramolecular hydroarylation (IMHA) of bromopropargyl aryl ethers and amines, and palladium-catalyzed cross-coupling reaction using triorganoindium reagents (R3In) has been ... -
Simple and Low-Cost Footstep Energy-Recover Barocaloric Heating and Cooling Device
(MDPI, 2021-10-10)[Abstract] In this work, we design, build, and test one of the very first barocaloric devices. The here presented device can recover the energy generated by an individual’s footstep and transform it into barocaloric heating ... -
Site-Selective C–H Amination of Phenol-Containing Biomolecules
(American Chemical Society, 2023-06-07)[Abstract] A C–N bond-forming cross-dehydrogenative coupling of a collection of Tyr-containing peptides and estrogens with heteroarenes is described. This oxidative coupling is distinguished by its scalability, operational ... -
