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.

1. It has been suggested that the toxic effect of toxoflavin (TXF) produced by Pseudomonas cocovenenas is mainly due to the impairment of electron transfer of the mitochondrial respiratory chain. However, the cardiovascular effect of TXF is unknown. In the

Burkholderia glumae is an emerging rice pathogen in several areas around the world. Closely related Burkholderia species are important opportunistic human pathogens for specific groups of patients, such as patients with cystic fibrosis and patients with chronic granulomatous disease. Here
The activated methyl cycle (AMC) is responsible for the generation of S-adenosylmethionine (SAM), which is a substrate of N-acylhomoserine lactone (AHL) synthases. However, it is unknown whether AHL-mediated quorum sensing (QS) plays a role in the metabolic flux of the
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

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
Cell cycle phases (G1, S, G2, M) regulate cell growth, DNA replication, and division in proliferating cells.
