Human Pleural Fluid Elicits Pyruvate and Phenylalanine Metabolism in Acinetobacter baumannii to Enhance Cytotoxicity and Immune Evasion [PDF]

, 2019
The CCAAT box-harboring proteins represent a family of heterotrimeric transcription factors which is highly conserved in eukaryotes. In fungi, one of the particularly important homologs of this family is the Hap complex that separates the DNA-binding ...

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Straightforward Preparation of Polyurethane‐Based Biomaterials with Dual Antibacterial and Anti‐Adhesive Properties for Long‐Lasting Catheter Applications

Advanced Materials Interfaces, EarlyView.
This study presents the elaboration of antibacterial, antiadhesive, and antibiofilm polyurethane by a straightforward process based on the co‐extrusion of 2 wt.% of both antibacterial and antiadhesive copolymer. The material proves to be active even after pre‐exposition to biological media and prevents E. coli biofilm formation without toxicity.

Bench‐Stable Boryl Thianthrenium Dication Enables Aziridinyl Boronate Synthesis via Metal‐Free Late‐Stage Aziridination with Diverse Nitrogen Nucleophiles

Angewandte Chemie, EarlyView.
A bench‐stable boryl thianthrenium dication is synthesized via thianthrenation of vinyl MIDA boronate. This novel dication enables metal‐free, chemo‐, and diastereoselective late‐stage aziridination with diverse nitrogen nucleophiles. The strategic significance is further showcased by one‐pot electrochemical and asymmetric protocols and versatile ...

Marine aerobic biofilm as biocathode catalyst [PDF]

, 2010
Stainless steel electrodes were immersed in open seawater and polarized for some days at − 200 mV vs. Ag/AgCl. The current increase indicated the formation of biofilms that catalysed the electrochemical reduction of oxygen.

Engineering of an Ancestral McbA with Enhanced Domain Mobility Extends Biocatalytic Amide Synthesis Scope

Advanced Synthesis &Catalysis, EarlyView.
We show how engineered ancestral amide bond synthetases (ABSs) together with cofactor recycling using a single polyphosphate kinase paves the way for chemoenzymatic synthesis of pharmacophores. The figure illustrates how ancestral ABS has a more flexible C‐terminal domain, which is associated with enhanced catalytic performance and expanded amine scope.

Evaluation of the Sensitivity of Acinetobacter sp. burn isolates to Ciprofloxacin and some of other used antibiotics for treatment

فصلنامه دانشگاه علوم پزشکی جهرم, 2009
Introduction: Acinetobacter sp. is usually considered to be opportunistic pathogens.  They are often multi-resistant to antibiotics, meaning that therapy and infection control are complicated.

Cinnamic‐Hydroxamic‐Acid Derivatives Exhibit Antibiotic, Anti‐Biofilm, and Supercoiling Relaxation Properties by Targeting Bacterial Nucleoid‐Associated Protein HU

Advanced Science, EarlyView.
Cinnamic‐hydroxamic‐acid derivatives (CHADs) are identified as novel inhibitors of the bacterial nucleoid‐associated protein HU, exhibiting potent antibacterial, anti‐biofilm (both inhibition and eradication), and DNA relaxation (anti‐supercoiling) activities. Moreover, CHADs demonstrate strong synergistic effects with multiple antibiotics.
