General description
Application
- Insights into the Mechanism of Catalytic Activity of Plasmodium Parasite Malate-Quinone Oxidoreductase.: This study elucidates the catalytic mechanism of malate-quinone oxidoreductase in Plasmodium parasites, revealing potential targets for antimalarial drugs and insights into enzyme activity modulation by acetic anhydride (Ito et al., 2024).
- Adsorption simulation of 2,4-D pesticide on novel zinc-based 2-amino-4-(1H-1,2,4-triazole-4-yl)benzoic acid coordination complexes using machine learning approach.: This research presents a novel adsorption method using zinc-based coordination complexes for the removal of pesticides, where acetic anhydride plays a crucial role in the synthesis of these complexes, demonstrating an innovative approach to environmental remediation (Mansab and Rafique, 2024).
