Glucokinase activators
Glucokinase (GK) is one of four hexokinases that are found in mammals [Colowick, S.P., in The Enzymes, Vol. 9 (P. Boyer, ed.) Academic Press, New York, NY, ~~ pages 1-48, 1973]. The hexokinases catalyze the first step in the metabolism of glucose, i.e., the conversion of glucose to glucose-6-phosphate. Glucokinase has a limited cellular distribution, being found principally in pancreatic -cells and liver parenchymal cells. In addition, GK is a rate-controlling enzyme for glucose metabolism in these two cell types that are known to play critical roles in whole-body glucose homeostasis [Chipkin, S.R.,
Kelly, K.L., and Ruderman, N.B. in Joslin's Diabetes (C.R. Khan and G.C. Wier, eds.),
Lea and Febiger, Philadelphia, PA, pages 97-115, 1994]. The concentration of glucose at which GK demonstrates half-maximal activity is approximately 8 mM. The other three hexokinases are saturated with glucose at much lower concentrations (<1 mM).
Therefore, the flux of glucose through the GK pathway rises as the concentration of glucose in the blood increases from fasting (5 mM) to postprandial (=10-15 mM) levels following a carbohydrate-containing meal [Printz, R.G., Magnuson, M.A., and Granner,
D.K.in Ann. Rev. Nutrition Vol. 13 (R.E. Olson, D.M. Bier, and D.B. McCormick, eds.),
Annual Review, Inc., Palo Alto, CA, pages 463-496, 1993]. These findings contributed over a decade ago to the hypothesis that GK functions as a glucose sensor in f-cells and hepatocytes (Meglasson, M.D. and Matschinsky, F.M. Amer. J. Physiol. 246, E1-E13, 1984). In recent years, studies in transgenic animals have confirmed that GK does indeed play a critical role in whole-body glucose homeostasis. Animals that do not express GK die within days of birth with severe diabetes while animals overexpressing GK have improved glucose tolerance (Grupe, A., Hultgren, B., Ryan, A. et al., Cell 83, 69-78, 1995; Ferme, T., Riu, E., Bosch, F. et al., FASEB 7. 10, 1213-1218, 1996). An increase in glucose exposure is coupled through GK in B-cells to increased insulin secretion and in hepatocytes to increased glycogen deposition and perhaps decreased glucose production.
The finding that type II maturity-onset diabetes of the young (MODY-2) is caused by loss of function mutations in the GK gene suggests that GK also functions as a glucose sensor in humans (Liang, Y., Kesavan, P., Wang, L. et al., Biochem. J. 309, 167-173, 1995). Additional evidence supporting an important role for GK in the regulation of } glucose metabolism in humans was provided by the identification of patients that express a mutant form of GK with increased enzymatic activity. These patients exhibit a fasting hypoglycemia associated with an inappropriately elevated level of plasma insulin (Glaser,
B., Kesavan, P., Heyman, M. et al., New England J. Med. 338, 226-230, 1998). While mutations of the GK gene are not found in the majority of patients with type II diabetes, compounds that activate GK and, thereby, increase the sensitivity of the GK sensor system will still be useful in the treatment of the hyperglycemia characteristic of all type
IT diabetes. Glucokinase activators will increase the flux of glucose metabolism in B-cells and hepatocytes, which will be coupled to increased insulin secretion. Such agents would be useful for treating type II diabetes.

The carboxylic acids and their lower alkyl esters of formula V wherein one of R' and R? is nitro, cyano, thio, amino, chloro, bromo, or iodo and the other is hydrogen are commercially available. In cases, where only the carboxylic acids are available, they can be converted to the corresponding esters of lower alkyl alcohols using any conventional ; esterification methods.

If desired, the lower alkyl thio or perfluoro-lower alkyl thio compounds can then be converted to the corresponding lower alkyl sulfonyl or perfluoro-lower alkyl sulfonyl substituted compounds of formula V by oxidation. Any conventional method of oxidizing alkyl thio substituents to sulfones can be utilized to effect this conversion.

On the other hand, the thio substituent can be oxidized to a -SOsH group which then can be converted to -SO,Cl which is reacted with ammonia to form the sulfonamide substituent -S(O),-NH,. If it is desired to produce compounds of formula V wherein one or both of R! and R? is hydroxyamino, the corresponding nitro compounds can be used as starting material and can be converted to the corresponding compounds where R' and/or R? are hydroxyamino.

The carboxylic acids or lower alkyl esters of formula V wherein both of R! and R? are chloro or fluoro are commercially available. In cases, where only the carboxylic acids are available, they can converted to the corresponding esters of lower alkyl alcohols using any conventional esterification method. To produce the compound of formula V where both R! and R? are nitro, 3,4-dinitrotoluene can be used as starting material. This compound can be converted to the corresponding 3,4-dinitrophenyl acetic acid. This conversion can take place either before or after the compound of formula V is converted to the compounds of formulae I-a, I-b, I-c or I-d. Any conventional method of converting ) ) an aryl methyl group to the corresponding aryl acetic acid can be utilized to effect this conversion (see for example, Clark, R. D.; Muchowski, J.

A.; Repke, D. B.; Souchet, M, Synthesis, 1991, 871). The compounds of formula V where both R' and R? substituents are amino can be obtained from the corresponding dinitro compound of formula V, described above. Any conventional method of reducing a nitro group to an amine can be utilized to effect this conversion. The compound of formula V where both R! and R? are amine groups can be used to prepare the

Any conventional method of converting amino group to an iodo or bromo group (see for example, Lucas, H. J.; Kennedy, E. R. Org. Synth. Coll. Vol, II 1943, 351) can be utilized to effect this conversion. If it is desired to produce compounds
S of formula V, where both R' and R? are lower alkyl thio or perfluoro-lower alkyl thio ~~ 7 ~~ groups, the compound of formula V where R' and R® are amino can be used as starting material. Any conventional method of converting aryl amino group to aryl thioalkyl group can be utilized to effect this conversion. If it is desired to produce compounds of formula
V where R' and R? are lower alkyl sulfonyl or lower perfluoro alkyl sulfonyl, the corresponding compounds of formula V where R' and R? are lower alkyl thio or perfluoro-lower alkyl thio can be used as starting material. Any conventional method of oxidizing alkyl thio substituents to sulfones can be utilized to effect this conversion.
If it is desired to produce compounds of formula V, where both R! and R? are substituted with lower alkyl or perfluoro-lower alkyl groups, the corresponding halo substituted compounds of formula V can be used as starting materials. Any conventional method of converting an aromatic halo group to the corresponding alkyl or perfluoro- lower alkyl group can be utilized to effect this conversion.
If it is desired to produce compounds of formula V, where one or both of R' and
R? are substituted with sulfonamido, the corresponding compounds where one or both of
R' and R? are substituted with nitro can be used as starting materials. Any standard method of converting a nitrophenyl compound to the corresponding sulfonamidophenyl compound can be used to effect this conversion.
