and/or resonance Raman spectroscopy, cyclic voltammetry, and, in eight cases, X-ray crystallography. Features of the active site geometries of the CuII−tyrosinate forms of galactose and glyoxal oxidases (GAO and GLO) were modeled by these complexes, including the binding of a redox-active phenolate and an exogenous ligand (Cl-, CH3CO2-, or CH3CN) in a cis-equatorial position of a square pyramidal metal

A method for inhibiting the growth of drug resistant cells in a subject, comprising identifying a subject having drug resistant cells; and administering to the subject a compound or a pharmaceutically acceptable salt or ester thereof, that is a MDR1 -inverse agent. Also disclosed is a method of inhibiting cancer in a subject, comprising administering to the subject an antiproliferative agent, wherein the antiproliferative effect of the agent is potentiated by P-glycoprotein and the agent is a compound, or a pharmaceutically acceptable salt or ester thereof, that is a MDR1 -inverse agent.

KLc2a–c by reaction with potassium hydride in tetrahydrofuran (THF). An improved synthesis of HLc1c is also reported. Reaction of KLa–c with Group 13 metal salts MCl3 (M = Al, Ga or In) gives monomeric derivatives [M(κ4-La–c)Cl2] 3–5 in good yields. The crystal structure of [In(κ4-Lb)Cl2] 5b has been determined and confirms the six-coordinate, cis-dichloride structures proposed for these complexes. Reaction
