Our recent publication in ACS Accounts of Chemical Research, among the top 3 most downloaded papers in the month of January

02/05/2019
So glad to announce our Acc. Chem. Res. manuscript is available as Article ASAP, and also getting an amazing acknowledgement and lots of attention

We are so pleased to annouce our publication at Account of Chemical Research is one of the top 3 most downloaded papers in January.
It is entitled "Allenes and Derivatives in Gold(I)- and Platinum(II)-Catalyzed Formal Cycloadditions" and authored by J. L. Mascareñas, I. Varela and F. López.

In this Account, we present recent efforts on the development of platinum- and gold-catalyzed formal cycloadditions of allenes, only including annulations initiated by a direct metal-promoted activation of the allene moiety.This Account is organized considering the number of atoms engaged in the annulation process, and when possible, we present the results in a chronological order.

Our last publication at Chem. Sci. highlighted today as 'Pick of the Week'

01/23/2019
We are really pleased to announce our recently accepted paper in the Chemical Science journal was selected as 'Pick of the Week'

Very happy to announce our latest paper at the Chemical Science journal, entitled "Hollow Nanoreactors for Pd-catalyzed Suzuki- Miyaura Couplings and O-Propargyl Cleavage Reactions in Bio-relevant Aqueous Media ", by P. Destito, A. Sousa-Castillo, J. R. Couceiro, F. López, M. Angel Correa-Duarte and J. L. Mascareñas has been selected by the Editorial Team as 'Pick of the Week'.
We describe the fabrication of hollow microspheres consisting of mesoporous silica nanoshells decorated with an inner layer of palladium nanoparticles, and their use as Pd-nanoreactors in aqueous media. These palladium-equipped capsules can be used to promote the uncaging of propargyl-protected phenols, as well as Suzuki-Miyaura cross-couplings, in water, and under physiologically compatible temperatures. Importantly, the depropargylation reaction can be accomplished in a bioorthogonal manner in presence of relatively high concentrations of biomolecular components, and even in the presence of mammalian cells.

Already on-line our first publication for 2019

01/13/2019
We are very pleased to announce our latest publication at J. Am. Chem. Soc. is already available

Glad to announce our most recent publication at the Journal of the American Chemical Society in this brand new 2019 year, entitled "Palladium-catalyzed, enantioselective formal cycloaddition between benzyltriflamides and allenes: Straightforward access to enantioen-riched isoquinolines" and authored by X. Vidal, J. L. Mascareñas and M. Gulías, is already available as just accepted manuscript.

Abstract:
Benzyl and allyltriflamides can engage in Pd-catalyzed oxidative (4+2) annulations with allenes, to produce highly valuable tetrahydroisoquinoline or dihydropyridine skeletons. The reaction is especially efficient when carried out in presence of designed N-protected amino acids as metal ligands. More importantly, using this type of chiral ligands, it is possible to perform desymmetrizing, annulative C-H activations of prochiral diarylmethylphenyl amides, and thus obtain the corresponding isoquinolines with high enantiomeric ratios.

Synthetic models in Chemical Biology

02/19/2019
Workshop on Nanomedicine 2012. Prof. Mascareñas, ERC - Advanced Grant METBIOCAT, explains his research lines in the chemical biology field.
DNA is the key macromolecule used by nature to store the genetic information, therefore containing all the instructions that control the day-to-day function of cells. As such, it has been a traditional target for the development of different type of drugs, particularly anticancer agents. These drugs include alkylating agents, like cis-platinum and derivatives, and non-covalent binders like the anthracyclines, which interact to DNA by intercalation between base pairs. There are other types of cytotoxic non-covalent DNA binders, like distamycin or propamidine, which interact to DNA by insertion in the minor groove.

We have been interested in this latter type of molecules, because they are sequence selective and therefore provide for molecular engineering of site-specific DNA-promoted processes. In particular, we have designed and synthesized a number of variants of propamidine that work as sequence specific DNA optical sensors, or as light-activated prodrugs.

Some of the knowledge acquired in the studies of light-promoted processes has been extended to area of DNA-protein interactions. In particular, we have developed a chemical approach to control the DNA interaction of synthetic mimics of transcription factors, and expect that the tactic can be used in the future to regulate processes of gene expression.
Part of our work in this area is also focused to the construction of optical sensors that can detect minute amounts of transcription factors considered as oncogenic biomarkers, like the bZIP protein Jun.
