A composition having an agent adapted to affect a multimeric protein by binding to a binding site of the multimeric protein and thereby affecting an equilibrium of units, wherein the multimeric protein has an assembly having a plurality of said units, wherein each of the units has a first complementary surface and a second complementary surface and wherein the first complementary surface of one unit is associated with the second complementary surface of another unit, provided that the assembly is at least one of different quaternary isoforms on a condition that in the multimeric protein (1) a structure of each of the units determines a structure of the different quaternary isoforms, (2) the units are in the equilibrium and (3) the structure of the different quaternary isoforms influences a function of the multimeric protein.

Rate and equilibrium constants for the deprotonation of a series of phenyl-substituted 2-tetralones in aqueous sodium hydroxide have been determined. A Bronsted plot of log k for deprotonation vs pK(a) of the appropriate 2-tetralone is linear with a slope (-alpha) of -0.60 +/- 0.01, except for the point corresponding to 6-nitro-2-tetralone (Ib). The negative deviation of Ib from the correlation indicates that the transition state for deprotonation of 2-tetralone is imbalanced, with delocalization of charge into the phenyl ring lagging behind proton transfer. A semiquantitative assessment of the charge distribution in both the fully formed anion and the transition stare for deprotonation was calculated from these results and C-13 NMR spectra of the 2-tetralone anion in methanol/water mixtures. Although approximately twice as much negative charge is localized on the oxygen than on the enolate carbon in the anion, slightly more charge is on the enolate carbon in the transition state.

The invention relates to ROR modulators; compositions comprising an effective amount of a ROR modulator; and methods for treating or preventing diseases associated with ROR. The invention is based in part on the discovery of ROR modulators which interact with RORa and/or RORy and thereby inhibit or induce RORa and/or RORy-activity, and RORa- and/or RORy-regulated target gene and protein expression.
