Abstract: The disclosure relates to novel compounds and methods of use of the compounds to maintain the G?i2 protein in its inactive GDP-bound state. The disclosure describes the knockdown or inhibition of G?i2 negatively regulated migration of breast and ovarian cancer cell lines. The novel compounds inhibit the migratory behavior of PC3, DU145 and E006AA prostate cancer cell lines. Specifically, the novel compounds block the activation of G?i2 in oxytocin-stimulated prostate cancer PC3 cells and inhibits the migratory capability of DU145 cells overexpressing constitutively active form of G?i2, under basal and EGF-stimulated conditions.
