Amino Acid–Viologen Hybrids: Synthesis, Cucurbituril Host–Guest Chemistry, and Implementation on the Production of Peptides
Barravecchia Prado, Liliana Inés; Neira, Iago; Pazos, Elena; Peinador, Carlos; García, Marcos D. (American Chemical Society, 2021-12-10)[Abstract] We present herein the development of a series of viologen–amino acid hybrids, obtained in good yields either by successive alkylations of 4,4′-bipyridine, or by Zincke reactions followed by a second alkylation ... -
CB[7]- and CB[8]-Based [2]-(Pseudo)rotaxanes with Triphenylphosphonium-Capped Threads: Serendipitous Discovery of a New High-Affinity Binding Motif
Neira, Iago; Peinador, Carlos; García, Marcos D. (American Chemical Society, 2022-05-06)[Abstract] The synthesis of new triphenylphosphonium-capped cucurbit[7]uril (CB[7])- and cucurbit[8]uril (CB[8])-based [2]rotaxanes was achieved by a simultaneous threading-capping strategy. While the use of CB[7] produced ... -
Controlled Binding of Organic Guests by Stimuli-Responsive Macrocycles
Blanco-Gómez, Arturo; Cortón, Pablo; Barravecchia Prado, Liliana Inés; Neira, Iago; Pazos, Elena; Peinador, Carlos; García, Marcos D. (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 ... -
The Red Cage: Implementation of pH-Responsiveness Within a Macrobicyclic Pyridinium-Based Molecular Host
Cortón, Pablo; Wang, Hongye; Neira, Iago; Blanco-Gómez, Arturo; Pazos, Elena; Peinador, Carlos; Li, Hao; García, Marcos D. (Royal Society of Chemistry, 2021-11-09)[Abstract] We present herein the implementation of pH-responsiveness into a new polycationic macrobicyclic structure, namely what we have termed the “red cage”. The hydrolytically-stable cryptand-like compound has been ... -
Thinking Outside the Blue Box: From Molecular to Supramolecular PH-Responsiveness
Blanco-Gómez, Arturo; Neira, Iago; Barriada, José Luis; Melle-Franco, Manuel; Peinador, Carlos; García, Marcos D. (Royal Society of Chemistry, 2019-10-23)[Abstract] We present herein the development of a new polycationic cyclophane: the “red box”, second in a series of hydrazone-based analogues of the well-known organic receptor cyclobis(paraquat-p-phenylene)cyclophane ... -
Vermellogens and the Development of CB[8]-Based Supramolecular Switches Using pH-Responsive and Non-Toxic Viologen Analogues
Barravecchia Prado, Liliana Inés; Blanco-Gómez, Arturo; Neira, Iago; Skackauskaite, Raminta; Vila García, Alejandro; Rey-Rico, Ana; Peinador, Carlos; García, Marcos D. (ACS, 2022-10-07)[Abstract] We present herein the “vermellogens”, a new class of pH-responsive viologen analogues, which replace the direct linking between para-substituted pyridinium moieties within those by a hydrazone functional group. ...
