The marine natural product ()-8,15-diisocyano-11(20)-amphilectene, isolated from the Caribbean sponge Svenzea flava, was used as scaffold to synthesize five new products, all of which were tested against laboratory strains of Plasmodium falciparum and Mycobacterium tuberculosis H.sub.37Rv. The scaffold contains two isocyanide units that are amenable to chemical manipulation, enabling them to be elaborated into a small library of sulfur and selenium compounds. The scaffold along with its isothio- and isoselenocyanate analogs has low to sub-micro molar antiplasmodial activity.

The present invention provides an isothiocyanate compound and its application. The compound is an aryl-substituted isothiocyanate compound that has a structure of the general formula I. The isothiocyanate compound of the present invention has very good solubility in water, far better inhibitory activity for XPO1 protein than other non-aryl substituted congeneric compounds, little side effects, and good biological safety and bioavailability, and is quite suitable for clinical application. Therefore, the isothiocyanate compound would have tremendous potential market space and economic benefits.
