aldisine and hydrazine

Marine natural products have attracted more and more attention in drug research and development due to their unique structure, diverse biological activities, and novel mode of action. Using antiviral alkaloid aldisine as the lead compound and drawing on the hydrogen bond effect widely used in drug design, derivatives containing oxime and hydrazone moieties were designed and synthesized by introducing functional groups with hydrogen-bond receptors or donors into molecules. The configuration of derivatives was systematically studied through nuclear Overhauser effect (NOE) spectroscopy and single crystal analysis. The antiviral activity test result showed that most derivatives had antiviral activity against tobacco mosaic virus (TMV), and some compounds had better activity than the commercial antiviral drug ribavirin, especially compounds
