Biochem/physiol Actions

PKF118-310 is an antagonist of the Tcf4/b-catenin signaling. The compound disrupts the Tcf4/b-catenin complex and inhibits expression of Tcf4 responsive genes. PKF118-310 inhibits expression of survivin and induces apoptosis in HCC, colon tumor and lymphocytic leukemia cell lines.

Toxoflavin (1,6-dimethylpyrimido[5,4-e][1,2,4]triazine-5,7-dione; xanthothricin) is a well-known natural toxin of the pyrimidinetriazinedione type that redox cycles with oxygen under reducing conditions. In mammalian systems, toxoflavin is an inhibitor of Wnt signaling as well as of SIRT1 and SIRT2 activities, but other

Eight novel toxoflavin glycosides, which are potential prodrugs in antibody directed enzyme prodrug therapy (ADEPT), were synthesized. The structures of all toxoflavin glycosides were characterized by (13)C NMR spectroscopy, elemental analysis, and MS. Their enzymatic hydrolysis activities were tested against

Photosensitizers are common in nature and play diverse roles as defense compounds and pathogenicity determinants and as important molecules in many biological processes. Toxoflavin, a photosensitizer produced by Burkholderia glumae, has been implicated as an essential virulence factor causing bacterial
