Allosteric interactions: Metal(II) cyclens inhibit Ras–effector interactions by stabilizing a weak effector-binding state of Ras, state 1(T), and binding directly in the active site. The novel state (1T) inhibitor Zn2+–BPA (BPA=bis(2-picolyl)amine) binds outside the nucleotide binding pocket but nevertheless allosterically stabilizes state 1(T) and thus inhibits the Ras–Raf interaction.
