A Crystal Structure of the Bifunctional Antibiotic Simocyclinone D8, Bound to DNA Gyrase [PDF]

, 2009
Simocyclinones are bifunctional antibiotics that inhibit bacterial DNA gyrase by preventing DNA binding to the enzyme. We report the crystal structure of the complex formed between the N-terminal domain of the Escherichia coli gyrase A subunit and ...

Systemic anti‐cancer therapy associated with the occurrence of peripheral neurotoxicity and, specifically, peripheral neuropathy

International Journal of Cancer, EarlyView.
What's New? While the effectiveness of systemic anticancer therapy is well documented, it commonly causes severe toxicity. This study of the 467 systemic anticancer therapy agents currently approved globally for clinical and/or research purposes found that peripheral neurotoxicity is associated with 45% of classical chemotherapies, 21% of targeted ...

In systemic sclerosis skin perfusion of hands is reduced and may predict the occurrence of new digital ulcers [PDF]

, 2017
Systemic sclerosis (SSc) patients are at high risk for the development of ischemic digital ulcers (DUs). The aim of this study was to assess in SSc patients a correlation between skin perfusion evaluated by LDPI and DUs and to evaluate the prognostic ...

Associations Between GLP‐1 Receptor Agonists and Alopecia: A Multi‐Centre Retrospective Analysis and Public Interest Trends

JEADV Clinical Practice, EarlyView.
ABSTRACT Background There is a growing body of literature suggesting that GLP‐1 receptor agonists (GLP‐1RAs) may be associated with hair loss; however, primary literature is sparse. Additionally, it is not well‐established which types of hair loss may be associated with GLP‐1RA use. Objectives This study aims to assess associations between GLP‐1RAs and

Aliphatic Poly(Carbonate)s with Acid Responsive Release Mechanisms for Micellar Anti‐Tumor Drug Delivery

Macromolecular Rapid Communications, EarlyView.
Micellar systems based on biodegradable aliphatic polycarbonates and acid‐responsive triggers enhance drug solubility, stability, and tumor‐selective release. This review covers micelles with acid‐cleavable drug linkages and those that disassemble via acid‐sensitive functionalities.

Enhancement of radiosensitivity by the novel anticancer quinolone derivative vosaroxin in preclinical glioblastoma models [PDF]

, 2017
Purpose: Glioblastoma multiforme (GBM) is the most aggressive brain tumor. The activity of vosaroxin, a first-in-class anticancer quinolone derivative that intercalates DNA and inhibits topoisomerase II, was investigated in GBM preclinical models as a ...

Topoisomerase I Inhibitors.

The oncologist
Topoisomerase I inhibitors are a new class of anticancer agents with a mechanism of action aimed at interrupting DNA replication in cancer cells, the result of which is cell death. Most if not all Topoisomerase I inhibitors are derivatives of the plant extract camptothecin.

Genome‐wide screen reveals a universal role of ATP in ciprofloxacin tolerance among genetically distinct Escherichia coli persisters

mLife, EarlyView.
Abstract Bacterial persisters show tolerance to bactericidal antibiotics and play essential roles in chronic infections; however, the general mechanisms underlying persister formation and antibiotic tolerance remain insufficiently characterized. In this study, the Escherichia coli Keio library was used to identify genes involved in ciprofloxacin ...
