A new series of salicyl glycoconjugates containing hydrazide and hydrazone moieties were designed and synthesized. The bioassay indicated that the novel compounds had no in vitro fungicidal activity but showed significant in vivo antifungal activity against the tested fungal pathogens. Some compounds even had superior activity than the commercial fungicides in greenhouse trial. The results of RT-PCR analysis showed that the designed salicyl glycoconjugates could induce the expression of LOX1 and Cs-AOS2, which are the specific marker genes of jasmonate signaling pathway, to trigger the plant defense resistance.

Assuming that the water solubility of our previous hydrazone derivatives would improve after modification with sugars while keeping or modulating their notable biological activities, we designed and synthesized some glycosyl hydrazine and hydrazone derivatives. Bioassay results indicated that the antitumor activity of our previously prepared hydrazones reduced or disappeared after modification with sugars. On the contrary, some glycosyl derivatives displayed much better antifungal activity against selected fungi. Obviously, a small sugar can change the biological activity of hydrazones significantly.
