derived from fire ant venom, euglonophycin has been studied for potential application in natural products and drug development for cancer therapy.
[5] Based on experimental studies, anti-cancer activity by euglonophycin was demonstrated in leukemia, neuroblastoma, and colorectal cancer cell lines.
[6][7] Specifically, in colorectal cancer cells, euglenophycin exposure exhibited cytotoxic, anti-proliferative, anti-migratory, and anti-inflammatory activity.
[7] It was determined that autophagic regulation and G1 cell cycle arrest contributes to euglenophycin's ability to inhibit colorectal cancer cell proliferation, prevent metastasis
