2-(1-Hexyn-1-yl)benzoic Acid is an intermediate in synthesizing Apigenin 5-O-β-D-Glucuronide (A426510), a metabolite of Apigenin (A726500), Induces the reversion of transformed phenotypes of v-H-ras-transformed NIH 3T3 cells at low concentration (12.5 uM) by inhibiting MAP kinase activity. Also inhibits the proliferation of malignant tumor cells by G2/M arrest and induces morphological differentiation. Apigenin has also been reported to enhance the gap junction intracellular communication in liver cells.
