Novel all-hydrocarbon stapled p110α[E545K] peptides as blockers of the oncogenic p110α[E545K]-IRS1 interaction.

Abstract excerpt

To follow up on our recent discovery of the 18-amino acid all-hydrocarbon [i, i + 4]-stapled p110α[E545K] peptide 1 that was shown to potently block the intracellular p110α[E545K]-IRS1 interaction (a protein-protein interaction uniquely present in cancer cells expressing p110α[E545K]) and the growth of the xenograft tumors formed by cancers harboring this mutation, in the current study we prepared and examined...
