Abstract: Atividade Antibacteriana de Austidiol Isolado de Mycoleptodiscus indicus Contra Xanthomonas axonopodis pv. passiflorae Resumo: Doenças de plantas causadas por bactérias resultam em perdas graves para a agricultura. O estudo químico de fungos endofíticos representa uma área em potencial no desenvolvimento de pesticidas biológicos. Assim, o presente trabalho teve como objetivo verificar a atividade antibacteriana do extrato do fungo endofítico Mycoleptodiscus indicus NF12 de Morinda citrifolia contra Xanthomonas… Show more

“…Compound 1 ( Figure 1 ) was obtained as a white powder and compound 2 ( Figure 1 ) was isolated as a yellow powder. They were identified as known azaphilones, 4,6-dimethylcurvulinic acid and austdiol, respectively, based on the comparison of their 1 H and 13 C NMR data with those reported in the literature ( Supplementary Figures S2 , S3 ) ( Liu et al, 2017 ; de Oliveira et al, 2019 ). The absolute configuration of 2 was further confirmed to be 7 R , 8 S by single crystal X-ray diffraction and ECD calculation ( Supplementary Figures S4 , S5 ) ( Presti et al, 2003 ).…”

“…Passiflorae, or on the control of other phytopathogenic bacteria. In a previous study, we reported antibacterial activity for the compound austdiol isolated from an endophytic fungus from Morinda citrifolia [3]. This study has now led us to study other endophytic fungi from Morinda citrifolia in search of extracts and/or bioactive compounds that act against bacterial spot.…”

“…The disease is quite distinctive and can be visually recognized by its typical symptoms, such as small wet lesions on leaves, which soon rot and present a brownish color. The leaves becomes dry and fall as the disease develops, considerably reducing yield [3]. Currently, the use of pesticides has been the main strategy to combat bacterial spot.…”
