Tetrahedral metal-organic cages with cube-like cavities for selective encapsulation of fullerene guests and their spin-crossover properties
Han, Wang-Kang,Zhang, Hai-Xia,Wang, Yong,Liu, Wei,Yan, Xiaodong,Li, Tao,Gu, Zhi-Guo
, p. 12646 - 12649 (2018)
Tetrahedral FeII4L6 coordination cages containing organic linkers with rigid π-electron aromatic rings and flexible alkyl units were constructed. Interestingly, these tetrahedral cages have rare cube-like cavities for selective encapsulation of fullerene guests. In addition, the solid state spin-crossover properties were influenced by guest binding of fullerene C60.

Pseudomonas aeruginosa (P.A.) is a human pathogen belonging to the top priorities for the discovery of new therapeutic solutions. Its propensity to generate biofilms strongly complicates the treatments required to cure P.A. infections. Herein, we describe the synthesis of a series of novel rotaxanes composed of a central galactosylated pillar[5]arene, a tetrafucosylated dendron, and a tetraguanidinium subunit. Besides the high affinity of the final glycorotaxanes for the two P.A. lectins LecA and LecB, potent inhibition levels of biofilm growth were evidenced, showing that their three subunits work synergistically. An antibiofilm assay using a double δlecAδlecB mutant compared to the wild type demonstrated that the antibiofilm activity of the best glycorotaxane is lectin-mediated. Such antibiofilm potency had rarely been reached in the literature. Importantly, none of the final rotaxanes was bactericidal, showing that their antibiofilm activity does not depend on bacteria killing, which is a rare feature for antibiofilm agents.
