Hydrogen sulphide-triggered theranostic prodrugs based on the dynamic chemistry of tetrazines
(Royal Society of Chemistry, 2022)
[EN] Dynamic nucleophilic aromatic substitution of tetrazines (S(N)Tz) has been employed to build theranostic prodrugs that are activated by hydrogen sulfide. H2S is typically found in high concentrations in some kinds of ...
Nature of Alkali- and Coinage-Metal Bonds Versus Hydrogen Bonds
(Wiley, 2021-01)
We have quantum chemically studied the structure and nature of alkali- and coinage-metal bonds (M-bonds) versus that of hydrogen bonds between A-M and B- in archetypal [A-M center dot center dot center dot B](-) model ...
Radiationless mechanism of UV deactivation by cuticle phenolics in plants
(Nature Research, 2022-04)
[EN] Hydroxycinnamic acids present in plant cuticles, the interphase and the main protective barrier between the plant and the environment, exhibit singular photochemical properties that could allow them to act as a UV ...

Preformulation Studies of a Stable PTEN-PDZ Lipopeptide Able to Cross an In Vitro Blood-Brain-Barrier Model as a Potential Therapy for Alzheimer's Disease
(Springer, 2020-08-04)
PurposeAmyloid beta (A beta) drives the accumulation of excess Phosphatase and Tensin Homolog Deleted on Chromosome 10 (PTEN) at synapses, inducing synaptic depression and perturbing memory. This recruitment of PTEN to ...
Manipulating the fluorescence lifetime at the sub-cellular scale via photo-switchable barcoding
(Nature, 2020-05-18)
Fluorescent barcoding is a pivotal technique for the investigation of the microscale world, from information storage to the monitoring of dynamic biochemical processes. Using fluorescence lifetime as the readout modality ...
Rigidochromism by imide functionalisation of an aminomaleimide fluorophore
(Royal Society Of Chemistry, 2021-08-21)
Fluorescent dyes that exhibit high solid state quantum yields and sensitivity to the mechanical properties of their local environment are useful for a wide variety of applications, but are limited in chemical diversity. ...
Additive and Emergent Catalytic Properties of Dimeric Unnatural Amino Acid Derivatives: Aldol and Conjugate Additions.
(Wiley, 2021-11-11)
[EN]Different densely substituted L- and D-proline esters were prepared by asymmetric (3+2) cycloaddition reactions catalyzed by conveniently selected EhuPhos chiral ligands. The gamma-nitro-2-alkoxycarbonyl pyrrolidines ...
Phenanthrene-Extended Phenazine Dication: An Electrochromic Conformational Switch Presenting Dual Reactivity
(American Chemical Society, 2022)
The synthesis and isolation of one of the few examples of a pi-extended diamagnetic phenazine dication have been achieved by oxidizing a phenanthrene-based dihydrophenazine precursor. The resulting dication was isolated ...
Site-Selective C - H Functionalization of Amino Acids and Peptides Upon Radical Chemistry
(2021-04-15)
El objetivo de esta Tesis Doctoral ha sido desarrollar nuevas metodologías de modificación selectiva decompuestos peptídicos. Por un lado, hemos estudiado metales alternativos como el cobalto para lamodificación C-H selectiva ...
