Natural Products from Antarctic Colonial Ascidians of the Genera Aplidium and Synoicum: Variability and Defensive Role
(Molecular Diversity Preservation International, 2012)
Ascidians have developed multiple defensive strategies mostly related to physical, nutritional or chemical properties of the tunic. One of such is chemical defense based on secondary metabolites. We analyzed a series of ...
Thinking Outside the Blue Box: Induced Fit within a Unique Self-Assembled Polycationic Cyclophane
(ACS, 2019-02-07)
[Abstract] We present herein the development of a new polycationic molecular receptor, inspired by the ubiquitous cyclobis(paraquat-p-phenylene)cyclophane (“blue box”). Our analogue, the “white box”, has been easily ...
