Overcoming Aminoglycoside Enzymatic Resistance: Design of Novel Antibiotics and Inhibitors

Molecules, 2018
Resistance to aminoglycoside antibiotics has had a profound impact on clinical practice. Despite their powerful bactericidal activity, aminoglycosides were one of the first groups of antibiotics to meet the challenge of resistance.

Self‐Assembled Nanostructured Microgels with Reconfigurable Morphologies

Small, EarlyView.
This work presents bent‐core amphiphiles that self‐assemble into fibrillar, tubular, and helical nanofiber‐like nanostructures, forming organogels that can be emulsified into water as nanostructured microgels. These droplets preserve internal architectures and, when combined with fluorocarbon oils, yield multicompartment emulsions with dynamically ...

Dendrimeric Antigens for Passive Mast Cell Activation in the Evaluation of Amoxicillin Allergy

Allergy, EarlyView.
DeAns with defined nanoscale structure reveal that conjugate size and determinant density govern IgE‐mediated effector‐cell activation in AX allergy. All DeAn generations bind to sIgE in inhibition immunoassay, but only larger DeAns trigger FcεRI‐dependent responses in mouse MC, huRBL‐2H3, and LUVA cells.

Monovalent mannose‐glycoconjugates of sulforaphane reprogram human dendritic cells via NFATc1 to induce immune tolerance under inflammatory conditions

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Immune tolerance prevents inflammation and autoimmunity, with dendritic cells (DCs) playing a key role. Reprogramming DCs towards a tolerogenic state represents a promising therapeutic strategy. Sulforaphane (SFN) has known immunomodulatory effects, but its clinical application is limited by poor stability and ...
