In the present investigation, inhibitory activity to the multiplication of tobacco mosaic virus (TMV) of thiosemicarbazones from benzaldehyde, acetophenone, cinnamaldehyde, and benzalacetone and the para-substituents of them was tested. Detached tobacco leaves which had been inoculated with TMV 24 hours before by rubbing with a juice of infected tobacco leaf, were split along the midrib. One half of each leaf was floated on solutions of the chemicals in Petri dishes and were kept at 25°under continuous illumination from fluorescent lamps. The another half was kept on water and served as control. After 5〜6 days, the leaves were removed, homogenized, and analyzed for TMV by means of ammonium sulphate-precipitation method previously reported. In some experiments, measurement of the amount of TMV was made by the method of Bancroft and Curtis, and was compared with the results of ammonium sulphate method. Results of the experiments are given in tables. 1〜4. The inhibitory activity of 21 thiosemicarbazones was determined and it was found that both unsubstituted and substituted benzalacetone thiosemicarbazones are effective, to some degree, to the inhibition of TMV multiplication. Benzaldehyde thiosemicarbazones had also some inhibitory activity on the virus, but not the substituted ones. Thiosemicarbazones from acetophenone and cinnamaldehyde with or without para-substituents showed no effect.
