Salicylic acid (SA) is widely used in food storage, preservatives, additives, healthcare, and the pharmaceutical industry. However, various poisoning symptoms are frequently reported upon ingestion of a large amount of SA. Therefore, discovering new tools for sensing SA with fast, simple, and portable performance is imperative.

Article Synopsis
  • Reactive oxygen species (ROS), reactive nitrogen species (RNS), and reactive sulfur species (RSS) are crucial for maintaining redox balance in the body, but imbalances can lead to health issues and diseases.
  • Small-molecule fluorescent probes are useful tools for detecting these reactive species due to their high sensitivity, non-invasive nature, and ability to provide real-time measurements.
  • The review focuses on the development of rhodamine-based fluorescent probes since 2016, discussing their design, mechanism of action, and applications in biological research.

Article Synopsis
  • Salicylic acid (SA) plays a crucial role in plant growth and immunity, aiding in pest control and food preservation, but research tools for studying its effects have been limited.
  • Three newly developed Rh6G-based chemosensors demonstrate rapid and selective detection of SA, allowing for effective imaging of SA in plant tissues and better understanding of its physiological roles.
  • The probes can also be applied in agricultural contexts to monitor SA levels, with visible results under UV light, addressing safety concerns due to SA's hazardous nature for sensitive individuals.

Article Synopsis
  • * Researchers created and tested three new sensors (R1-R3) that can detect SA, using modified rhodamine-acylhydrazone compounds, with varying effectiveness.
  • * The best sensor, R2 (3-hydroxyphenyl variant), detected SA at low concentrations (0.9 μM) quickly, indicating its potential for further research into SA's role in plant immunity.

Nowadays, reactive oxygen species (ROS) have been acknowledged as promising bactericidal targets against pesticide-resistant bacteria. Herein, to further excavate more excellent ROS inducers, simple 1,2,3,4-tetrahydro-β-carboline derivatives containing a 3-aminopropanamide moiety were prepared and assessed for their antibacterial potency. Notably, three promising compounds displayed significant antibacterial potency.

Plant bacterial diseases are an intractable problem due to the fact that phytopathogens have acquired strong resistances for traditional pesticides, resulting in restricting the quality and yield of agricultural products around the world. To develop new agrochemical alternatives, we prepared a novel series of sulfanilamide derivatives containing piperidine fragments and assessed their antibacterial potency. The bioassay results revealed that most molecules displayed excellent in vitro antibacterial potency towards pv.

Background: Gradually aggravated disease caused by phytopathogenic bacteria severely restricts food security and crop yield, and few pesticides can relieve this severe situation. Thus, development and excavation of new agrochemicals with high bioactivity and novel action mechanism may be a feasible strategy to control intractable bacterial diseases. As a privileged molecular framework, steroid molecules exhibit diversiform bioactivities.
