Autor: Mateusz P. Plesniak, Monserrat H. Garduño-Castro, Philipp Lenz, Xavier Just-Baringo, David J. Procter

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-9 (2018)

Diversity-oriented synthesis is a valuable strategy to construct complex molecules of medicinal interest. Here, the authors show a folding cascade strategy to convert linear substrates into polycyclic compounds with multiple stereocentres by combinin

Thiopeptide Antibiotics: Retrospective and Recent Advances

Autor: Xavier Just-Baringo, Fernando Albericio, Mercedes Álvarez

Publikováno v: Marine Drugs, Vol 12, Iss 1, Pp 317-351 (2014)

Thiopeptides, or thiazolyl peptides, are a relatively new family of antibiotics that already counts with more than one hundred different entities. Although they are mainly isolated from soil bacteria, during the last decade, new members have been iso

Evidence for Site-Specific Reversible Hydrogen Adsorption on Graphene by Sum-Frequency Generation Spectroscopy and Density Functional Theory

Autor: Yexin Feng, Sven P. K. Koehler, Xingxing Jiang, Huda S. AlSalem, Umberto Monteverde, Xavier Just-Baringo, Igor Larrosa

We have characterized the C−H stretching vibrations of hydrogenated graphene on gold substrates using vibrational sum-frequency generation (SFG) spectroscopy. These C−H stretches are red-shifted as compared to aliphatic C−H stretches, and SFG s
