Heterophyllin B is an active cyclic peptide isolated from Pseudostellaria heterophylla. Heterophyllin B provides a novel strategy for the treatment of esophageal cancer[1].

Heterophyllin B (0-200 μM; 12-48 hours) reduces cell viability in the 75, 100 and 200 μM groups, has no effect on 5, 10, 25 and 50 μM groups[1].Heterophyllin B (0-50 μM; 6 hours) suppresses the expression levels of p-PI3K, p-AKT and β-catenin in a dose-dependent manner in ECA-109 cells[1]. Cell Viability Assay[1] Cell Line: ECA-109 cells
