Cyanomethylquinolones as a New Class of Potential Multitargeting Broad-Spectrum Antibacterial Agents

Journal of Medicinal Chemistry, Journal Year: 2024, Volume and Issue: 67(11), P. 9028 - 9053

Published: May 24, 2024

This work identified a class of cyanomethylquinolones (CQs) and their carboxyl analogues as potential multitargeting antibacterial candidates. Most the prepared compounds showed high activities against most tested bacteria, exhibiting lower MIC values (0.125–2 μg/mL) than those clinical norfloxacin, ciprofloxacin, clinafloxacin. The low hemolysis, drug resistance, cytotoxicity, well good predictive pharmacokinetics active CQs revealed development potential. Furthermore, they could eradicate established biofilm, facilitating bacterial exposure to these These induce death through effects, including intercalating into DNA, up-regulating reactive oxygen species, damaging membranes directly, impeding metabolism. Moreover, highly cyclopropyl CQ 15 exhibited more effective in vivo anti-MRSA potency ciprofloxacin. findings highlight broad-spectrum candidates for treating intractable infections.

Unique Azolyl Acylhydrazonyl Hybridization of Aloe Emodins to Access Potential Antibacterial Agents

Chinese Journal of Chemistry, Journal Year: 2024, Volume and Issue: 42(15), P. 1741 - 1758

Published: March 26, 2024

Comprehensive Summary A type of unique azole‐hybridized acylhydrazonyl aloe emodins (AAEs) were developed as new antibacterial agents for combating bacterial infections. Some target AAEs showed strong activities, especially, tetrazolylthioether AAE 27a exhibited broad spectrum with 16—256 folds and 8—64 more active efficacy than the reference drugs emodin norfloxacin, respectively. Tetrazolylthioether also gave low hemolysis cytotoxicity, well favorable bioavailability. Preliminary mechanism explorations revealed that could cause membrane depolarization damage cell membrane, resulting in nucleic acid leakage. Moreover, compound intercalate into DNA to impede its replication form supramolecular ‐DNA gyrase complex disturb function gyrase. These findings would provide valuable insights further exploration azolyl potential candidates.

Discovery of Quinazolone Pyridiniums as Potential Broad-Spectrum Antibacterial Agents

Molecules, Journal Year: 2025, Volume and Issue: 30(2), P. 243 - 243

Published: Jan. 9, 2025

The overprescription of antibiotics in medicine and agriculture has accelerated the development spread antibiotic resistance bacteria, which severely limits arsenal available to clinicians for treating bacterial infections. This work discovered a new class heteroarylcyanovinyl quinazolones quinazolone pyridiniums surmount increasingly severe resistance. Bioactive assays manifested that highly active compound 19a exhibited strong inhibition against MRSA Escherichia coli with extremely low MICs 0.5 μg/mL, being eightfold more than norfloxacin (MICs = 4 μg/mL). rapid bactericidal properties displayed imperceptible trends, negligible hemolytic toxicity, effective biofilm inhibitory effects. Preliminary explorations on antibacterial mechanisms revealed could cause membrane damage, embed intracellular DNA hinder replication, induce metabolic dysfunction. Surprisingly, was found trigger conformational change PBP2a open site, might account its high MRSA. In addition, little effect molecule production reactive oxygen species indicated death not caused by oxidative stress. above comprehensive analyses highlighted large potential as multitargeting broad-spectrum agents.
