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.
cross resistance to the analog (4Oa) having a tetrazole moiety as a substituent of glutamine, which exhibited potent antitumor activities. These results demonstrate that the antifolate analogs (4) with N5-substituted glutamine in place of glutamicacid are novel potent DHFR inhibitors with activity against MTX-resistant tumors. The potent antitumor activity of these analogs (4) may result from their
The present invention is directed to method of using a collection of monomers capable of forming multimers as a fluorescence reporter in different applications such as ligand detection/screening, disease diagnosis, drug discovery or screening, fluorescent labeling and imaging, or other fluorescent methodologies. Each monomer in the collection includes one or more ligand elements useful for binding to a target molecule with a dissociation constant of less than 300 μM and a linker element connected to the ligand elements directly or indirectly through a connector. Association of linker elements of different combinations of monomers, with their ligand elements bound to the target molecule to form a multimer, will generate a unique fluorescent signature different from that produced by those monomers either alone or in association with each other in the absence of the target molecule, when subjected to electromagnetic excitement.
Selected compounds are effective for prophylaxis and treatment of diseases, such as HGF mediated diseases. The invention encompasses novel compounds, analogs, prodrugs and pharmaceutically acceptable salts thereof, pharmaceutical compositions and methods for prophylaxis and treatment of diseases and other maladies or conditions involving, cancer and the like. The subject invention also relates to processes for making such compounds as well as to intermediates useful in such processes.
