Helichrysetin

Helichrysetin has mild anti-HIV-1 PR activity. Helichrysetin has great potentials for development as an anticancer agent, it has cytotoxic effect on four selected cancer cell lines, A549, MCF-7, Ca Ski, and HT-29.Searching for anti-HIV-1 protease (PR) inhibitors of Thai medicinal plants led to the isolation of a new cyclohexenyl chalcone named panduratin C and chalcone derivatives from the methanol extract of Boesenbergia pandurata rhizomes. The known compounds were identified to be panduratin A, hydroxypanduratin A, Helichrysetin, 2',4',6'-trihydroxyhydrochalcone, and uvangoletin . The structures of all compounds were elucidated on the basis of chemical and spectroscopic methods.
