Versatile types of polysaccharide-based supramolecular polycation/pDNA nanoplexes for gene delivery.
Different polysaccharide-based supramolecular polycations were readily synthesized by assembling multiple β-cyclodextrin-cored star polycations with an adamantane-functionalized dextran via host-guest interaction in the absence or presence of bioreducible linkages. Compared with nanoplexes of the starting star polycation and pDNA, the supramolecular polycation/pDNA nanoplexes exhibited similarl...
Novel heteroleptic iridium complexes containing the 1-substituted-4-phenyl-1H-1,2,3-triazole (phtl) cyclometalating ligand have been synthesized. The 3+2 Huisgen dipolar cycloaddition method ('click' chemistry) was utilized to prepare a class of bidentate ligands (phtl) bearing different substituents on the triazole moiety. By using various ligands (phtl-R1 and pytl-R2) (R1 = adamantane, methyl...
In the title compound, C(19)H(19)ClN(4)S, the 2-chloro-phenyl and [1,2,4]triazolo[3,4-b] [1,3,4]thia-diazole fragments (r.m.s. deviations of 0.015 and 0.017 Å, respectively) are oriented at a dihedral angle of 55.76 (6)°. The adamantane group exhibits extensive rotational disorder about the single C-C bond to the thia-diazole ring, which was modelled as occupying four orientations each with 0.2...

Herein, we present the synthesis of two novel adamantane appended supramolecular self-associating amphiphiles. The antimicrobial efficacy these compounds is determined against both clinically relevant Gram-positive methicillin-resistant Staphylococcus aureus and Gram-negative Escherichia coli. We also explore self-associative properties amphiphiles in polar organic DMSO-d6 0.5% H2O (D2O)/EtOH 1...
A small-sized graphene oxide supramolecular assembly was obtained by the inclusion complexation of hyaluronated adamantane with β-cyclodextrin and the π-stacking of graphene oxide with camptothecin, exhibiting an excellent stability in the serum environment and a higher inhibition effect toward malignant cells than a free drug.
The photochemical reaction of La@C82 with 2-adamantane-2,3-[3H]-diazirine affords adduct 2, La@C82(Ad), in a quantitative and highly selective manner. The structure of compound 2 is confirmed by ESR, MS, and UV-vis-NIR spectroscopies, and the first X-ray crystallographic characterization of an endohedral monometallofullerene derivative is reported.
Beyond measurements of equilibria: An alpha-hemolysin nanopore is used as a single-molecule sensor to follow the effects of different salts on the complexation reaction of gamma-cyclodextrin and adamantane carboxylate (see picture). The kinetics underlying the dynamic equilibrium are studied to reveal qualitatively different dynamic actions of various cosolute salts.
