Heterocyclic‐Based Fungicides: Emerging Strategies for Viable Plant Disease Control

open access: yesChemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Heterocyclic compounds have attracted considerable attention because of their structural diversity, potent antifungal activity, and ability to interact with multiple fungal targets, offering broad‐spectrum protection against phytopathogens. Synthetic and semisynthetic/part‐natural scaffolds, particularly azole, quinoline, indole, cyclotryptamine, and ...

Clean Synthesis of N‐4‐Alkylamino‐7‐chloroquinoline Cyclic Imides: Influence of Lipophilicity on Antibacterial and Ecotoxicological Properties

open access: yesChemistry &Biodiversity, Volume 23, Issue 9, September 2026.
For series 2a–d, there appears to be optimal activity against Klebsiella pneumoniae when lipophilicity is intermediate (log P 2.64 for 2b). Similarly, for series 2e–g, activity against Pseudomonas aeruginosa, Staphylococcus aureus and Streptococcus mutans also increases (log P 3.71 for 2f).

Polyphenol‐Based Biomaterials for Antibacterial Infection Management: From Assembly Chemistry to Infection Site‐Specific Therapeutic Platforms

open access: yescMat, Volume 3, Issue 3, September 2026.
Polyphenol assembly chemistry provides a versatile basis for antibacterial biomaterials. Matching material format and function to the distinct barriers of wound, respiratory, intestinal, and implant‐associated infections is central to effective and translatable design. ABSTRACT Bacterial infections involving multidrug‐resistant pathogens and persistent
