Abstract
![]()
Injectable, self-healing hydrogels with enhanced solubilization
of hydrophobic drugs are urgently needed for antimicrobial intravaginal
therapies. Here, we report the first hydrogel systems constructed
of dynamic boronic esters cross-linking unimolecular micelles, which
are a reservoir of antifungal hydrophobic drug molecules. The selective
hydrophobization of hyperbranched polyglycidol with phenyl units in
the core via ester or urethane bonds enabled the solubilization of
clotrimazole, a water-insoluble drug of broad antifungal properties.
The encapsulation efficiency of clotrimazole increases with the degree
of the HbPGL core modification; however, the encapsulation is more
favorable in the case of urethane derivatives. In addition, the rate
of clotrimazole release was lower from HbPGL hydrophobized via urethane
bonds than with ester linkages. In this work, we also revealed that
the hydrophobization degree of HbPGL significantly influences the
rheological properties of its hydrogels with poly(acrylamide-ran-2-acrylamidephenylboronic acid). The elastic strength
of networks (GN) and the thermal stability
of hydrogels increased along with the degree of HbPGL core hydrophobization.
The degradation of the hydrogel constructed of the neat HbPGL was
observed at approx. 40 °C, whereas the hydrogels constructed
on HbPGL, where the monohydroxyl units were modified above 30 mol
%, were stable above 50 °C. Moreover, the flow and self-healing
ability of hydrogels were gradually decreased due to the reduced dynamics
of macromolecules in the network as an effect of increased hydrophobicity.
The changes in the rheological properties of hydrogels resulted from
the engagement of phenyl units into the intermolecular hydrophobic
interactions, which besides boronic esters constituted additional
cross-links. This study demonstrates that the HbPGL core hydrophobized
with phenyl units at 30 mol % degrees via urethane linkages is optimal
in respect of the drug encapsulation efficiency and rheological properties
including both self-healable and injectable behavior. This work is
important because of a proper selection of a building component for
the construction of a therapeutic hydrogel platform dedicated to the
intravaginal delivery of hydrophobic drugs.

Abstract
![]()
Shiga toxin is an
AB5 toxin produced by Shigella species, while related toxins are produced
by Shiga toxin-producing Escherichia coli (STEC). Infection by Shigella can lead to bloody diarrhea followed
by the often fatal hemolytic uremic syndrome (HUS). In the present
paper, we aimed for a simple and effective toxin inhibitor by comparing
three classes of carbohydrate-based inhibitors: glycodendrimers, glycopolymers,
and oligosaccharides. We observed a clear enhancement in potency for
multivalent inhibitors, with the divalent and tetravalent compounds
inhibiting in the millimolar and micromolar range, respectively. However,
the polymeric inhibitor based on galabiose was the most potent in
the series exhibiting nanomolar inhibition. Alginate and chitosan
oligosaccharides also inhibit Shiga toxin and may be used as a prophylactic
drug during shigella outbreaks.

Abstract
We here report on the synthesis of a bifunctional nanocarrier system based on amphiphilic hyperbranched polyglycerol (hPG), which is modified by introducing hydrophobic aromatic groups to the core and retaining hydrophilic groups in the shell. "Selective chemical differentiation" and chemo-enzymatic reaction strategies were used to synthesize this new core-shell type nanocarrier. The system shows an innovative bifunctional carrier capacity with both polymeric and unimolecular micelle-like transport properties. Hydrophobic guest molecules such as pyrene were encapsulated into the hydrophobic core of modified hPG via hydrophobic interactions as well as π-π stacking, analogous to a unimolecular micelle system. A second guest molecule, which has a high affinity to the shell like nile red, was solubilized in the outer shell of the host molecule, thus connecting the nanocarrier molecules to form aggregates. This model is confirmed by UV-Vis, fluorescence, atomic force microscopy, and dynamic light scattering, as well as release studies triggered by pH-changes and enzymes. Encapsulated guest molecules, respectively in the core and in the shell, present different controlled release profiles. The bifunctional nanocarrier system is a promising candidate for simultaneous delivery of different hydrophobic drugs for a combination therapy, e.g., in tumor treatment.

Abstract
A new class of non-ionic dendronized multiamphiphilic polymers is prepared from a biodegradable (AB)n-type diblock polymer synthesized from 2-azido-1,3-propanediol (azido glycerol) and polyethylene glycol (PEG)-600 diethylester using Novozym-435 (Candida antarctica lipase) as a biocatalyst, following a well-established biocatalytic route. These polymers are functionalized with dendritic polyglycerols (G1 and G2) and octadecyl chains in different functionalization levels via click chemistry to generate dendronized multiamphiphilic polymers. Surface tension measurements and dynamic light scattering studies reveal that all of the multiamphiphilic polymers spontaneously self-assemble in aqueous solution. Cryogenic transmission electron microscopy further proves the formation of multiamphiphiles towards monodisperse spherical micelles of about 7-9 nm in diameter. The evidence from UV-vis and fluorescence spectroscopy suggests the effective solubilization of hydrophobic guests like pyrene and 1-anilinonaphthalene-8-sulfonic acid within the hydrophobic core of the micelles. These results demonstrate the potential of these dendronized multiamphiphilic polymers for the development of prospective drug delivery systems for the solubilization of poorly water soluble drugs.
