The term “pharmaceutically acceptable” as used herein, refers to a material, (e.g., a carrier or diluent), which does not abrogate the biological activity or properties of the compounds described herein, and is relatively nontoxic (i.e., the material is administered to an individual without causing undesirable biological effects or interacting in a deleterious manner with any of the components of the composition in which it is contained).
The term “modulate,” as used herein, means to interact with a target either directly or indirectly so as to alter the activity of the target, including, by way of example only, to enhance the activity of the target, to inhibit the activity of the target, to limit the activity of the target, or to extend the activity of the target.
II. MEK
In certain instances, Ras is a signal transduction protein. In certain instances, Ras is activated by the binding of guanosine nucleotides, GTP (Guanosine triphosphate) or GDP (Guanosine diphosphate).
In certain instances, the activation of Ras results in the activation of a cascade of serine/threonine kinases. In certain instances, activated Ras activates Raf proteins. In certain instances, activated Raf proteins activate “MEK1” and “MEK2.”
MEK1 and MEK2 are dual-function serine/threonine and tyrosine protein kinases that, in certain instances, activate MAPK. In certain instances, activation of MAP kinase by mitogens appears induces cellular proliferation. In certain instances, constitutive activation of MAPK induces cellular transformation. In certain instances, blockade of downstream Ras signaling, as by use of a dominant negative Raf-1 protein, inhibits mitogenesis, whether induced from cell surface receptors or from oncogenic Ras mutants.

Preparation of crystalline polymorph Form A of N—(S)-(3,4-difluoro-2-(2-fluoro-4-iodophenylamino)-6-methoxyphenyl)-1-(2,3-dihydroxypropyl)cyclopropane-1-sulfonamide
Preparation i) N—(S)-(3,4-difluoro-2-(2-fluoro-4-iodophenylamino)-6-methoxyphenyl)-1-(2,3-dihydroxypropyl) cyclopropane-1-sulfonamide (216.10 g) was charged to a 4 L Erlenmeyer flask equipped with a large magnetic stir bar and a magnetic stirrer/hot plate. Ethyl Acetate (ca. 600 mL, purchased from Fisher) was added. Heating and stirring were initiated to form a brown suspension. The mixture was brought to a low reflux and additional ethyl acetate (ca. 200 mL) was added to effect complete dissolution giving a dark brown solution. Heptane (purchased from Acros) was slowly added portionwise to the refluxing solution at a rate that all precipitates that formed on each addition were quickly dissolved and reflux maintained. Upon the addition of 2 L of heptanes to the solution the solids formed dissolved very slowly at reflux. Heating was stopped and the crystallization mixture allowed to equilibrate to room temperature with stirring over 16 h. A thick layer of crystalline material developed around the surface of the glass over the aging period. The resulting suspension was equilibrated in an ice/water bath with stirring. The suspension was filtered on a 25 cm Buchner funnel dressed with Whatman #1 filter media. The collected crystals were washed with heptanes (1 L) and allowed to air dry under vacuum, The crystals were further dried at 40° C./<1 torr over 20 h to yield the product as a pink crystalline solid (160.99 g, 77.2%).

Stirring and heating to low reflux were initiated to effect complete dissolution giving a dark brown solution. Hexanes were slowly added portionwise to the refluxing solution at a rate that all precipitates that formed on each addition were quickly dissolved and reflux maintained, until the addition of hexanes to the solution caused the solids formed to dissolve very slowly at reflux ( ̃2 L hexanes), Heating was stopped and the crystallization mixture allowed to equilibrate to room temperature with stirring over 16 h. A thick layer of crystalline material developed around the surface of the glass over the aging period. The resulting suspension was equilibrated in an ice/water bath with stirring. The suspension was filtered on Buchner funnel dressed with Whatman #1 filter media. The collected crystals were washed, and allowed to air dry under vacuum. The crystals were further dried at 40° C./<1 torr over 20 h to yield the product as a pink crystalline solid.

Preparation of crystalline polymorph of N—(R)-(3,4-difluoro-2-(2-fluoro-4-iodophenylamino)-6-methoxyphenyl)-1-(2,3-dihydroxypropyl)cyclopropane-1-sulfonamide
N—(R)-(3,4-difluoro-2-(2-fluoro-4-iodophenylamino)-6-methoxyphenyl)-1-(2,3-dihydroxypropyl) cyclopropane-1-sulfonamide (216.10 g) is charged to a 4 L Erlenmeyer flask equipped with a large magnetic stir bar and a magnetic stirrer/hot plate. Ethyl Acetate (ca. 600 mL) is added. Heating and stirring are initiated to form a brown suspension. The mixture is brought to a low reflux and additional ethyl acetate (ca. 200 mL) is added to effect complete dissolution giving a dark brown solution. Heptane is charged to the solution slowly portionwise to the refluxing solution at a rate that all precipitates that form on each addition are quickly dissolved and reflux is maintained. Upon the addition of 2 L of heptanes to the solution the solids formed dissolve very slowly at reflux. Heating is stopped and the crystallization mixture is allowed to equilibrate to room temperature with stirring over 16 h. A thick layer of crystalline material develops around the surface of the glass over the aging period. The resulting suspension is equilibrated in an ice/water bath with stirring. The suspension is filtered on a 25 cm Buchner funnel dressed with Whatman #1 filter media. The collected crystals are washed with heptanes (1 L) and allowed to air dry under vacuum. The crystals are further dried at 40° C./<1 torr over 20 h.

Generation of IC50 Data
Materials and preparation of reagents: Human GST-MEK1 and the constitutively active allele GST-MEK1CA (harboring the mutations Ser218Asp and Ser222Asp) were subcloned into the yeast expression vector pGEM4Z (Promega, Madison, Wis.) from the wild type human MEK1 cDNA. GST-MEK1CA was expressed in Escherichia coil and partially purified using Glutathione Sepharose 4B affinity resin (Amersham Pharmacia Biotech, Piscataway, N.J.). The ERK2 allele was subcloned from MAPK2/Erk2 cDNA (wild type) in pUSEamp (Upstate Biotechnology, Inc., Waltham, Mass.) into the vector pET21a (Novagen, Madison, Wis.) resulting in an N-terminal histidine-tagged mouse ERK2 allele. ERK2 was expressed and purified to homogeneity [Zhang, 1993 #33]. Myelin basic protein (MBP) was purchased from Gibco BRL (Rockville, Md.). EasyTides adenosine 5′-triphosphate (ATP) ([γ-33P]) (NEN Perkin Elmer, Wellesley, Mass.) was the source of radiolabel for all kinase reactions. Activated Raf-1 (truncated) and activated MAPKinase 2/ERK2 were purchased from Upstate, Inc. (Lake Placid, N.Y.). 4-20% Criterion Precast gels were purchased from Bio-Rad (Hercules, Calif.).
Determination of enzymatic activity: Compounds were diluted from dimethylsulfoxide (DMSO) stocks into 1xHMNDE (20 mM. HEPES pH 7.2, 1 mM MgCl2, 100 mM NaCl, 1.25 mM DTT, 0.2 mM EDTA). A typical 25-microliter assay contained 0.002 nanomoles MEK1CA, 0.02 nanomoles ERK2, 0.25 nanomoles MBP, 0.25 nanomoles unlabeled ATP, and 0.1 μCi [γ33P] ATP. The screening assay essentially comprised four additions. Five μl of diluted compound were dispensed to 96-well assay plates. Ten μl of 2.5× enzyme cocktail (MEK1CA and ERK2 only) were then added to each well followed by a pre-incubation for 30 minutes at ambient temperature. Ten μl of 2.5× substrate cocktail (labeled and unlabeled ATP plus MBP) were then added, followed by incubation for 60 minutes at ambient temperature. Finally, 100 μl of 10% trichloroacetic acid (TCA) were added and incubated for 30 minutes at room temperature to halt the reaction and precipitate radiolabeled protein products. Reaction products were harvested on glass fiber 96 well filter plates prewetted with water and 1% pyrophosphate. The filter plate was then washed 5 times with water. Water was displaced by absolute ethanol and the plate was allowed to air dry for 30 minutes at room temperature. A back seal was applied manually and 40 μl of scintillation cocktail were dispensed to each well. A top seal was applied and the plate was counted in the TopCount for two seconds per well. For certain experiments a truncated version of MEK that requires activation by Raf kinase were used.

Generation of EC50 Data
Effects of compounds in the cell were determined by Western blotting for phosphorylated ERK. MDA-MB-231 breast cancer cells were plated in a 48 well plate at 20,000 cells per well and grown in a 37° humidified CO2 incubator. The following day, the growth media (DMEM+10% fetal bovine serum) was removed and replaced with starve media (DMEM+0.1% fetal bovine serum). Cells were incubated in the starve media for sixteen hours and then treated with a range of compound concentrations for thirty minutes. After incubation with compound, cells were stimulated with 100 ng/ml EGF for five minutes. The cells were then lysed and analyzed by Western blot using a monoclonal antibody raised to phosphorylated ERK. The signal was amplified using a secondary antibody conjugated to a near-IR dye and detected on a Licor Odyssey scanner. The intensity of signal was quantitated and this data was used to generate dose response curves and EC50 calculations.
