J Med Chem

January 2025

State Key Laboratory for Diagnosis and Treatment of Severe Zoonotic Infectious Diseases, Key Laboratory for Zoonosis Research of the Ministry of Education, Institute of Zoonosis, and College of Veterinary Medicine, Jilin University, Changchun 130062, China.

To date, the abuse of antibiotics and a gradual decline in novel antibiotic discovery enlarge the threat of drug-resistant bacterial infections, especially methicillin-resistant (MRSA). Herein, inspired by the unique structures and antibacterial activities of 2-quinolones, a class of novel 2-quinolones with substituted pyridines was synthesized. Notably, compound , the derivative with a methylpyridine fragment, showed potent antibacterial and antibiofilm activities, especially for MRSA strains (MIC = 0.

This editorial focuses on the issue of data misuse that is increasingly evidenced in social media as well as some premiere scientific journals. This issue is of critical importance to open science projects in general, and ABCD in particular, given the broad array of biological, behavioural and environmental information collected on this American sample of 12,000 youth and parents. ABCD data are already widely used with over 1,200 publications and twice as many citations per year as expected (relative citation index based on year, field and journal).

Objective: Accelerated ageing indexed by telomere attrition is suggested in schizophrenia spectrum- (SCZ) and bipolar disorders (BD). While inflammation may promote telomere shortening, few studies have investigated the association between telomere length (TL) and markers of immune activation and inflammation in severe mental disorders.

Methods: Leucocyte TL defined as telomere template/amount of single-copy gene template (T/S ratio), was determined in participants with SCZ ( = 301) or BD ( = 211) and a healthy control group (HC, = 378).
