Inhibition of rice-blast fungus <i>Magnaporthe oryzae</i> by <i>Piper betle</i> extracts: <i>in vitro</i> evidence and <i>in silico</i> prediction
View through CrossRef
Developing new antimicrobial agents towards Magnaporthe oryzae based on Piper betle extracts is practicable if an inhibition mechanism is known. The information for the retrieval was collected from experimental investigations and computational researches on the inhibitability of the plant extract compositions (P1 – P14) towards the fungus trehalose-6-phosphate synthase (PDB-6JBR). Gas chromatography-mass spectrometry characterisation determines 4-Chromanol (P5), 1’-Hydroxychavicol acetate (P6), Eugenol acetate (P7), and 4-Allyl-1,2-diacetoxybenzene (P8) making up the majority of Piper betle extract composition. Bio-assays provide experimental evidence of a total antifungal effect towards M. oryzae. Docking-based simulation confirms the significant static stability of P5-6JBR, P6-6JBR, P7-6JBR, and P8-6JBR. QSARIS analysis exceptionalises bio-compatibility of P5, P6, P7, and P8. The results prove the antifungal potentiality of Piper betle extracts and suggest trehalose-6-phosphate synthase as a promising target for M. oryzae inhibition.
