Two New Furan-2-Carboxylic Derivatives from the Leaves of Nicotiana tabacum and Their Anti-Tobacco Mosaic Virus Activities
Two new furan-2-carboxylic derivatives ( 1 and 2 ), together with three known compounds ( 3–5 ), were isolated from the leaves of Nicotiana tabacum. Their structures were determined by means of HR-ESI-MS and extensive 1D and 2D NMR spectroscopic studies. Compounds 1 and 2 were tested for their anti-...

| Zusammenfassung: | Two new furan-2-carboxylic derivatives (
1
and
2
), together with three known compounds (
3–5
), were isolated from the leaves of Nicotiana tabacum. Their structures were determined by means of HR-ESI-MS and extensive 1D and 2D NMR spectroscopic studies. Compounds
1
and
2
were tested for their anti-TMV activities. The results showed that compounds
1
and
2
exhibited high anti-TMV activity with inhibition rates of 33.2 and 30.8%. These rates are close to that of positive control. |
