Two xanthones 1 and 2, together with nine known compounds were obtained from the whole plant of Hypericum sampsonii. This is the first report of sulfonated xanthonoids. Compounds 1 and 2 exhibited significant cytotoxicity to P388 cancer cell line. Xanthones, 1,3-dihydroxy-5-methoxyxanthone-4-sulfonate and 1,3-dihydroxy-5-O-β-d-glycopyranosylxanthone-4-sulfonate, together with nine known compounds were obtained from H. sampsonii. This is the first report of sulfonated xanthonoids. Furthermore, compounds 1 and 2 exhibited significant cytotoxicity against the P388 cancer cell line.

Upregulation of phosphoglycerate mutase 1 (PGAM1) has been identified as one common phenomenon in a variety of cancers. Inhibition of PGAM1 provides a new promising therapeutic strategy for cancer treatment. Herein, based on our previous work, a series of new N-xanthone benzenesulfonamides were discovered as novel PGAM1 inhibitors. The representative molecule 15h, with an IC50 of 2.1 μM, showed an enhanced PGAM1 inhibitory activity and higher enzyme inhibitory specificity compared to PGMI-004A, as well as a slightly improved antiproliferative activity.

Topoisomerase II poison blocks the transitorily generated DNA double-strand breaks (DSBs) from religation, thereby causes severe DNA damage and gene toxicity. While topoisomerase II catalytic inhibitor does not form cleavable DNA-enzyme complex because its function attributes to inhibition of the catalytic steps of the enzyme such as before generating DNA DSBs or in the last step of the catalytic cycle after religation. It has been reported that the stabilizing effect of etoposide on transient cleavable DNA-topoisomerase IIβ complex attributes to its secondary malignancy. Therefore, topoisomerase IIα has been considered as more attractive target than topoisomerase IIβ for the development of chemotherapeutic agents. In the previous work, we reported compounds I and II as novel topoisomerase IIα catalytic inhibitors targeting for ATP binding site of human topoisomerase IIα ATP-binding domain. As a continuous work, we have designed and synthesized 43 compounds of C1-O-alkyl and arylalkyl substitiuted compounds with or without methoxy group on ring A. In the topoisomerase IIα inhibitory test, among the tested C1-O-4-chlorophenethyl substituted compounds 37 and 47 were more active than others, and compound 37 showed strongest topoisomerase IIα inhibitory activity with 94.4% and 23.0% inhibition, respectively, at 100 and 20?μM. Compounds 37 and 47 have also showed much enhanced cytotoxic activity against T47D cells; IC50(μM): 0.63?±?0.01 and 0.19?±?0.02, respectively, which are stronger than reference drugs. Band depletion assay and cleavage complex assay results showed compounds 37 and 47 were potential topoisomerase IIα catalytic inhibitor with low DNA damage.
