Controlled Binding of Organic Guests by Stimuli-Responsive Macrocycles
(Royal Society of Chemistry, 2020-05-12)[Abstract] Synthetic supramolecular chemistry pursues not only the construction of new matter, but also control over its inherently dynamic behaviour. In this context, classic host–guest chemistry, based on the development ... -
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 ... -
In Vitro and In Vivo Assessment of the Efficacy of Bromoageliferin, an Alkaloid Isolated from the Sponge Agelas dilatata, against Pseudomonas aeruginosa
(MDPI, 2020-06-23)[Abstract] The pyrrole-imidazoles, a group of alkaloids commonly found in marine sponges belonging to the genus Agelas, display a wide range of biological activities. Herein, we report the first chemical study of the ... -
Marine Organisms from the Yucatan Peninsula (Mexico) as a Potential Natural Source of Antibacterial Compounds
(MDPI, 2020-07-18)[Abstract] A total of 51 sponges (Porifera) and 13 ascidians (Chordata) were collected on the coast of the Yucatan Peninsula (Mexico) and extracted with organic solvents. The resulting extracts were screened for antibacterial ... -
Antiviral and Antiproliferative Potential of Marine Organisms from the Yucatan Peninsula, Mexico
(Frontiers, 2020-08-20)[Abstract] Viral infections are one of the main human health problems in recent decades and the cancer remains one of the most lethal diseases worldwide. The development of new antiviral drugs for the treatment of human ... -
Relative Configuration of Micrograms of Natural Compounds Using Proton Residual Chemical Shift Anisotropy
(Nature, 2020-09-01)[Abstract] 3D molecular structure determination is a challenge for organic compounds or natural products available in minute amounts. Proton/proton and proton/carbon correlations yield the constitution. J couplings and ... -
Development of Antibacterial Steel Surfaces Through Laser Texturing
(AIP Publishing, 2020-09-22)[Abstract] The aim of the present study was to develop novel antibacterial touch surfaces through the laser texturing optimization of stainless steel. A wide range of laser fluence (2.11 J/cm2–5.64 J/cm2) and scanning ... -
