Biological target: Mefentrifluconazole is a potent, selective and orally active fungal CYP51 (Kd= 0.5 nM) inhibitor, but shows less inhibitory activity on human aromatase (IC50=0.92 μM).
In vitro activity: In this study, the DMI fungicide mefentrifluconazole exhibited excellent inhibitory activity against the mycelial growth of S. rolfsii, with a mean EC50 value of 0.21 ± 0.11 mg L-1 and a range of 0.02 to 0.55 mg L-1 for 261 isolates collected from Hebei, Henan and Shandong provinces. Mefentrifluconazole significantly reduced the biomass of mycelia and affected the morphology of hyphae. Reference: Pest Manag Sci. 2023 Jan 29. https://pubmed.ncbi.nlm.nih.gov/36710267/
In vivo activity: The 96-h lethal concentration 50 (LC50) values (exposed to racemate and enantiomers of MFZ (mefentrifluconazole), that is, rac-MFZ/(-)-MFZ/(+)-MFZ) were 1.010, 1.552, and 0.753 mg/L for embryo, and 0.753, 1.187, and 0.553 mg/L for larvae. The rac-MFZ/(-)-MFZ/(+)-MFZ can affect the heart development of zebrafish embryos, accompanied by heart rate inhibition, yolk sac deformities, pericardial deformities, and down-regulation of genes related to cardiotoxicity in larvae in an enantioselective manner. Moreover, the rac-MFZ/(-)-MFZ/(+)-MFZ also can affect the neural development of zebrafish embryos, accompanied by autonomic movement inhibition, swimming speed and swimming distance abnormalities, and down-regulation of genes related to neurotoxicity in larvae in an enantioselective manner.
