Synthesis and biological activity of methylated derivatives of the Pseudomonas metabolites HHQ, HQNO and PQS

open access: yesBeilstein Journal of Organic Chemistry, 2019
Selectively methylated analogues of naturally occurring 2-heptyl-4(1H)-quinolones, which are alkaloids common within the Rutaceae family and moreover are associated with quorum sensing and virulence of the human pathogen Pseudomonas aeruginosa, have been

Artificial Intelligence‐Guided Phenotypic Drug Repurposing Against Streptococcus pneumoniae

open access: yesAdvanced Science, EarlyView.
Integrated artificial intelligence (AI) ensembles identify highly potent repurposed drugs against Streptococcus pneumoniae. Prospective virtual screening of 6747 drugs uncovers nine active candidates, including thiostrepton. This drug exhibits low picomolar potency and bypasses established resistance in multidrug‐resistant strains, demonstrating an ...

Bioinspired Porphyrin‐Based Catalysts From Temporospatial Confined Frameworks for Ultrafast Removal of Sulfaclozine

open access: yesAdvanced Science, EarlyView.
We report the rational design of artificial photocatalysts with asymmetrically coordinated dual‐metal centers and a tailored microenvironment, broadly applicable strategy is established for the synthesis of multivariate zirconium‐based metal–organic frameworks, offering a platform for precisely tuning active‐site configurations to optimize ...

Thermal Shifts Dominate Single‐Gene Responses to Transcription‐Targeting Antibiotics

open access: yesAdvanced Science, EarlyView.
Thermal shifts reshape bacterial responses to transcription‐targeting antibiotics. In E. coli, temperature can dominate antibiotic‐induced genome‐wide expression, particularly outside 30°C–39°C, through changes in adenosine triphosphate (ATP), nucleoid organization, and drug‐target engagement.

Superacid-catalyzed tandem Meyer–Schuster rearrangement/intramolecular hydroamination of o-anilinopropargyl alcohols for the synthesis of 2,3-dihydro-4(1H)-quinolones

open access: yes, 2016
A TfOH-catalyzed synthesis of 2,3-dihydro-4(1H)-quinolones from o-anilinopropargyl alcohols was developed. Studies of N-protecting groups and substituents in phenyl rings showed that diverse groups could be applied. By controlling the catalyst loading, o-

Reconfigurable Ternary Logic‐In‐Memory With Organic Antiambipolar Transistor

open access: yesAdvanced Electronic Materials, EarlyView.
We develop a ternary logic‐in‐memory with an organic antiambipolar transistor combining a ternary inverter and ternary nonvolatile memory in the same circuit. The memory function of the circuit enables electrical reconfiguration to obtain standard, negative, and positive ternary inverters in the same device.

T cell-mediated hypersensitivity to quinolones: mechanisms and cross-reactivity

open access: yes, 2006
BACKGROUND: Quinolones are widely used, broad spectrum antibiotics that can induce immediate- and delayed-type hypersensitivity reactions, presumably either IgE or T cell mediated, in about 2-3% of treated patients.

Rewriting Tumor Immunity With Bacterial Membrane Vesicles: A Versatile and Potent Therapeutic Strategy

open access: yesAdvanced NanoBiomed Research, EarlyView.
Bacterial membrane vesicles (BMVs) emerge as promising platforms for cancer immunotherapy owing to their intrinsic adjuvant properties and tunable cargo delivery capabilities. Their ability to modulate the tumor microenvironment, enhance antitumor immune responses, and support personalized therapeutic strategies highlights their growing potential as ...

Quinolone Allergy

open access: yesPharmacy, 2019
Quinolones are the second most common antibiotic class associated with drug-induced allergic reactions, but data on quinolone allergy are scarce. This review article discusses the available evidence on quinolone allergy, including prevalence, risk ...

Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...
