Equally, can synthesize other compound of the present invention, see Table 1.
Pyridine of table 1 phenanthroindolizididerivative and phenanthro-quinoline in western piperidine derivatives and salt thereof
Embodiment 3: the mensuration of activity of resisting tobacco mosaic virus, the mensuration program is as follows: with the withered spot method of half leaf (HalF-leafnecrosis), get fresh typical tobacco mosaic virus (the Tobacco mosaic virus that has, TMV) three lives tobacco leaf of viral symptom, (0.01M pH7.2), grinds in mortar to add phosphate buffer solution, on the western tobacco leaf of the coral that spreads diamond dust, inoculate, and get express developed with clear water.Inoculate after 1.5-2 hour, will inoculate blade and be cut into two equal half leaves along master pulse, a half vane soaks the leaf processing with the DMF solution of test compounds, and second half is dipped in the clear water and compares, and after 72 hours, adds up half leaf withered spot number.Calculate inhibiting rate by following formula:
Inhibiting rate=100 * [(contrast blade withered spot number-dispenser blade withered spot number)/contrast blade withered spot number]
Table 2 is the test result of part of compounds.
The withered spot method of table 2 half leaf is measured the anti-TMV activity of each sample (concentration 10ug/mL)
