Abstract
This invention provides novel polydentate selective high affinity ligands (SHALs) that can be used in a variety of applications in a manner analogous to the use of antibodies. SHALs typically comprise a multiplicity of ligands that each bind different region son the target molecule. The ligands are joined directly or through a linker thereby forming a polydentate moiety that typically binds the target molecule with high selectivity and avidity.
Claims20
A method of inhibiting the growth or proliferation of a cancer cell that expresses an HLA-DR10 marker, said method comprising:
- contacting said cancer with a selective high-affinity polydentate ligand (SHAL), the SHAL comprising a first ligand, a second ligand and a third ligand:
- wherein said first ligand binds to a first site on a marker for said cancer cell linked to a second ligand that binds a second site on the same marker or a different marker for said cancer cell wherein said first site and said second site are different sites;
- and
- wherein at least said first ligand is a ligand selected from the group consisting of BOC-4-aminomethyl-L-Phe, 4[[5-(Trifluoromethyl)pyridin-2-yl]oxy]phenyl]N-phenylcarbamate, (R)-2-[4-(5-chloro-3-fluoro-2-pyridyloxy)phenoxy]propionic acid, 2-(((3-chloro-5(trifluoromethyl)pyridin-2-yloxy)phenoxy)methyl)acrylates, 2-(((3-chloro-5(trifluoromethyl)pyridin-2-yloxy)phenyl)methyl)acrylates, 2-(((3-chloro-5(trifluoromethyl)pyridin-2-yloxy)phenyl)methyl)acrylonitriles, 3-(3-chloro-4-{[5-(trifluoromethyl)-2-pyridinyl]oxy}anilino)-3-oxopropanoic acid, Sethoxydim, Clethodim, 5-(Tetradecyloxy)-2-furoic acid, 2-[(2,6-Dichlorophenyl)amino]benzeneacetic acid, 2-[4-(4-Chlorophenoxy)phenoxy]propanoic acid, (RS)-2-{4-[3-chloro-5-(trifluoromethyl)-2-pyridinyl]oxy]phenoxy}propanoic acid, (RS)-2-[4-(6-chloro-1,3-benzoxazol-2-yloxy)phenoxy]propanoic acid, (RS)-2-[4-(2,4-dichlorophenoxy)phenoxy]propanoic acid, (RS)-2-{4-[5-(trifluoromethyl)-2-pyridyloxy]phenoxy}propanoic acid, (RS)-2-[4-(6-chloroquinoxalin-2-yloxy)phenoxy]propanoic acid, (RS)-2-[4-(α, α, α-trifluoro-p-tolyloxy)phenoxy]propanoic acid, 5-([4,6-Dichlorotriazin-2-yl]amino)fluorescein hydrochloride, 3-[N-(4-acetylphenyl)carbomoyl]pyridine-2-Carboxylic acid, 3-(2-{[3-chloro-5-(trifluoromethyl)-2-pyridinyl]oxy}anilino)-3-oxopropanoic acid, L-ornithine-beta-alanine, 2-Methyl-1-(3-morpholinopropyl)-5-phenyl-1H-pyrrole-3-carboxylic acid, Hippuric acid, Hippuryl-D-lysine, and hippuryl-L-phenylalanine.
