General description

Benzothiazole, a volatile sulfur-containing heterocyclic compound, is one of the key odorants of heated milk. It is also reported to occur as a flavor component of miso, coconut meat and cooked-beef.

Application


  • Modulating mycobacterial envelope integrity for antibiotic synergy with benzothiazoles.: This publication explores the role of benzothiazoles in enhancing antibiotic efficacy against mycobacteria. The study provides insights into how chemical modification of microbial cell envelopes can improve drug delivery and efficacy (Habjan et al., 2024).

  • An activatable fluorescence probe for rapid detection and in situ imaging of β-galactosidase activity in cabbage roots under heavy metal stress.: This research uses benzothiazole-based probes for real-time and in situ imaging of enzyme activity in plants under stress conditions, facilitating the study of environmental stress impacts on plant physiology and providing a tool for agricultural biotechnology (Zhao et al., 2024).
