Circular dichroism measurements show that β-cyclodextrin with an amino moiety has a strong binding ability for ferrocenecarboxylic acid in dimethyl sulfoxide via an acid-base interaction.

Page/Page column 97-99; 100, (2019/10/01)
Disclosed herein are cyclodextrin molecules covalently modified to store and release nitric oxide, as well as methods of making and uses thereof. The covalently modified cyclodextrin molecules may be tailored, in several embodiments, to release nitric oxide in a controlled manner and are useful for reduction and/or eradication of bacteria and for the treatment of disease.

A series of secondary amine-modified cyclodextrin (CD) derivatives was synthesized with diverse exterior terminal groups (i.e., hydroxyl, methyl, methoxyl, and primary amine). Subsequent reaction with nitric oxide (NO) gas under alkaline conditions yieldedN-diazeniumdiolate-modified CD derivatives. Adjustable NO payloads (0.6-2.4 μmol/mg) and release half-lives (0.7-4.2 h) were achieved by regulating both the amount of secondary amine precursors and the functional groups around the NO donors. The bactericidal action of these NO-releasing cyclodextrin derivatives was evaluated againstPseudomonas aeruginosa, a Gram-negative pathogen, with antibacterial activity proving dependent on both the NO payload and exterior modification. Materials containing a high density of NO donors or primary amines exhibited the greatest ability to eradicateP. aeruginosa. Of the materials prepared, only the primary amine-terminated heptasubstituted CD derivatives exhibited toxicity against mammalian L929 mouse fibroblast cells. The NO donor-modified CD was also capable of delivering promethazine, a hydrophobic drug, thus demonstrating potential as a dual-drug-releasing therapeutic.
