“…The most promising host was the cationic octakis (6-(2-aminoethylthio)-6-deoxy)--CD that formed the strongest complex with oxacillin and both reduced the hydrolysis rate of oxacillin and demonstrated a safe cytotoxicity pro¯le. 18 Similarly, Li and colleagues developed D-mannose-grafted--CD (CD-MAN) and Dglucose-grafted--CD (CD-GLU) via the click reaction and later complexed these sugar-modi¯ed CDs with erythromycin, rifampicin and cipro°oxacin. 19 The minimum inhibitory concentrations (MICs) of the loaded antibiotics against various bacteria were decreased by a factor of 3 to >100.…”

“…We saw CD 1 as an ideal scaffold for elaboration with peptides. It has been used for the design of a variety of supramolecular constructs due to the ease of elaborating the primary amines. CD 1 also features an extended hydrophobic cavity with improved guest binding over native β‐CD .…”

“…135 Thus, ITC studies were performed in order to obtain valid thermodynamic parameters for all the possible interactions between the CD-hosts and the penicillin-guests in aqueous solution and the detailed results are published. 136 In brief, solutions of all penicillins were titrated with increasing amounts of CD- The area underneath each injection peak was integrated, normalized according to the molar host : guest ratio and fitted to a 1 : 1 complexation thermodynamic model (Figure 3.21b). The binding constant (Kb) values were determined for each case and the results are presented in Table 3.7.…”

“…Biological experiments were performed in order to demonstrate the ability of GCYS to protect OXA against enzymatic hydrolysis and study its internalization into bacterial cells. 136 The hydrolytic activity of oxa-1, a β-lactamase highly active against OXA, induces full degradation of the drug with relative Vmax = 282.58 μM min -1 . In the presence of four equivalents of GCYS, the hydrolysis rate of OXA was Cytotoxicity and cell proliferation tests were carried out to address the biosafety of GCYS, up to 1000 mg mL -1 .…”
