A compound of formula (I) or its pharmaceutically acceptable salt is prepared by ring opening of osthol under basic condition. The compound of formula (I) or its pharmaceutically acceptable salt has activity of selectively inhibiting tumor cells and lower toxicity, and can be used for preparing anti-tumor drugs.

Structural modification of natural products is one of the important ways in the discovery of novel pesticides. Based on a diversity-oriented synthesis strategy, herein, two series of amide/ester derivatives (52 compounds) were obtained by opening the lactone of osthole. Interestingly, the effect of different concentrations of aq. sodium hydroxide on the ratio of two isomers (cis- and trans-2) was investigated

Abstract Isolation of a new piperidinealkaloid and 2′,4′,6′,4-tetramethoxychalcone from Excoecharia agallocha is reported. The structure 2,4-dimethoxy-3-ψ,ψ-dimethylallyl- trans -cinnamoylpiperidide assigned to the alkaloid was confirmed through synthesis.
