  • Six new diketopiperazines (1-6), two new sesquilignans (7-8), and ten known compounds (9-18) were isolated from the branches and leaves of Claoxylon polot. Their structures were elucidated by extensive spectroscopic analysis. The absolute configurations of 1-3 were assigned by computational methods. Compounds 1 and 2 exhibited antiviral activity against Coxsackie B3 virus with IC50 values of 14.6 and 25.9 µM, respectively.
