The Natural Product Corramycin Acts as a DNA Gyrase Poison and Overcomes Fluoroquinolone Resistance in Mycobacterium tuberculosis

open access: yesAdvanced Science, EarlyView.
Corramycin, a myxobacterial natural product antibiotic, exhibits potent bactericidal activity against multidrug‐resistant Mycobacterium tuberculosis. The compound hijacks bacterial transporters such as BacA and OppABCD to enter the cell and inhibits DNA synthesis through a previously unrecognized mode of DNA gyrase poisoning, locking the enzyme in an ...

Extrapolation and pharmacokinetic protocol design optimization for ceftriaxone as an exemplar for the development of antibiotics for children

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aim Ceftriaxone is a cephalosporin commonly used for the treatment of acute, severe infections; however, there are conflicting data on its disposition properties in children, making it a suitable case study for the evaluation of the appropriateness of extrapolation approaches based on exposure matching principles for paediatric patients and exploring ...

Die Funktion der Helix 8 für die Regulation des Bradykinin B2 Rezeptors [PDF]

open access: yes, 2012
Upon activation the human bradykinin B2 receptor (B2R) acts as guanine nucleotide exchange factor for the G proteins Gq/11 and Gi. Thereafter, it gets phosphorylated by G protein-coupled receptor kinases (GRKs) and recruits beta-arrestins, which block ...

Effects of bradykinin on the survival of multiterritory perforator flaps in rats

open access: yesWorld Journal of Surgical Oncology, 2019
Background Bradykinin, a vasoactive peptide, has many biological functions. For example, it accelerates angiogenesis. Thus, we studied the effects of bradykinin on the survival of perforator flaps.

A Unified Approach for the Synthesis of Conformationally Locked and sp2‐sp3 Fused Hybrids

open access: yesChemistry – A European Journal, EarlyView.
This study presents a systematic platform to build rigid sp2–sp3 hybrids via benzyne cycloadditions. Arene‑fused bicyclic oxa‐, aza‐, and carbocycles are converted into medicinally relevant amino acids and applied to Enalapril analogues synthesis. The hybrids combine aromatic interactions with 3D rigidity, tuning lipophilicity, pKa, and solubility ...

Cardiac remodelling in the era of the recommended four pillars heart failure medical therapy

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1029-1044, April 2025.
Abstract Cardiac remodelling is a key determinant of worse cardiovascular outcome in patients with heart failure (HF) and reduced ejection fraction (HFrEF). It affects both the left ventricle (LV) structure and function as well as the left atrium (LA) and the right ventricle (RV).

Inhibition of sequestration of human B-2 bradykinin receptor by phenylarsine oxide or sucrose allows determination of a receptor affinity shift and ligand dissociation in intact cells [PDF]

open access: yes, 2004
Depending on their interaction with intracellular proteins, G proteincoupled receptors (GPCR) often display different affinities for agonists at 37degreesC. Determining the affinity at that temperature is often difficult in intact cells as most GPCRs are

Ranakinestatin-PPF from the Skin Secretion of the Fukien Gold-Striped Pond Frog, Pelophylax plancyi fukienensis: A Prototype of a Novel Class of Bradykinin B2 Receptor Antagonist Peptide from Ranid Frogs

open access: yesThe Scientific World Journal, 2014
The defensive skin secretions of many amphibians are a rich source of bradykinins and bradykinin-related peptides (BRPs). Members of this peptide group are also common components of reptile and arthropod venoms due to their multiple biological functions

Connecting the dots: A narrative review of the relationship between heart failure and cognitive impairment

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1119-1131, April 2025.
Abstract Large clinical data underscore that heart failure is independently associated to an increased risk of negative cognitive outcome and dementia. Emerging evidence suggests that cerebral hypoperfusion, stemming from reduced cardiac output and vascular pathology, may contribute to the largely overlapping vascular dementia and Alzheimer's disease ...
