YW3-56 is an inhibitor of protein arginine deiminases PAD2 and PAD4 which convert protein arginine residues to citrulline. The IC₅₀ for inhibition of PAD4 and PAD2 is about 1–2 μM and 0.5–1 μM respectively. YW3-56 inhibits the growth of osteosarcoma U2OS cells with an IC₅₀ of 2.5 μM. YW3-56 induces p53 target genes SESN2 and DDIT4 which repress mTORC1 kinase activity. It perturbs autophagy and inhibits the growth of triple-negative breast cancer xenograft tumors in mice. It is a small-molecule inhibitor of eukaryotic translation initiation factor 4E (eIF4E), a protein involved in the regulation of mRNA translation and protein synthesis. It specifically targets and inhibits the activity of the eIF4E protein. By doing so, it disrupts the translation initiation complex, which is necessary for the synthesis of specific proteins involved in cancer cell growth and survival.
