Acyl thiourea derivatives for sustainable rice blast disease management

Overview

Acyl thiourea derivatives are being developed as a novel solution for managing rice blast disease, caused by the pathogen Magnaporthe oryzae. These compounds have shown significant potential as antifungal and pesticidal agents. They offer a sustainable alternative to conventional fungicides, which are increasingly facing resistance issues. By forming strong interactions with biological targets, acyl thioureas can effectively combat this destructive disease and contribute to enhanced agricultural productivity.

Technical specifications

The synthesis of acyl thiourea derivatives involves efficient, modular methods, utilizing aroyl chlorides, ammonium thiocyanate, and aromatic amines in a one-pot process. The key features include:

• Synthesis verified through NMR, IR, and LC-MS characterization.
• Strong antifungal activity evidenced through in vitro assays.
• Structure–activity relationship (SAR) analysis guides compound optimization.
• Potential for structural modification to enhance activity via electron-donating or withdrawing groups.
• Biodegradable and environmentally sustainable solution for crop protection.

Technology readiness level

This technology is currently at TRL 4, indicating that component and/or system validation has been achieved in a laboratory environment. Further development and testing are required to advance the technology for commercial application.
