  inhibited PfGSK-3, with four of these compounds exhibiting IC50 values in the sub-micromolar range (0.00048–0.440 µM). Evaluation of the structure-activity relationships required for PfGSK-3 selective inhibition indicated that a C6-OCH3 substitution on ring A is preferred, while the effect of the ring B substituent on activity, in decreasing order is: C4′-CN > C4′-F > C3′-OCH3 > C3′,4′-diCl.

  Described herein are monomers capable of forming a biologically useful multimer when in contact with one, two, three or more other monomers in an aqueous media. In one aspect, such monomers may be capable of binding to another monomer in an aqueous media (e.g. in vivo) to form a multimer, (e.g. a dimer). Contemplated monomers may include a ligand moiety, a linker element, and a connector element that joins the ligand moiety and the linker element. In an aqueous media, such contemplated monomers may join together via each linker element and may thus be capable of modulating one or more biomolecules substantially simultaneously, e.g., modulate two or more binding domains on a protein or on different proteins.
