Definitions
- the present invention relates to a new class of cyanopyrazoles, pharmaceutical compositions containing these compounds, and their use to modulate the activity of the G-protein-coupled receptor, GPR1 19.
- Diabetes mellitus are disorders in which high levels of blood glucose occur as a consequence of abnormal glucose homeostasis.
- the most common forms of diabetes mellitus are Type I (also referred to as insulin-dependent diabetes mellitus) and Type II diabetes (also referred to as non-insulin-dependent diabetes mellitus).
- Type II diabetes accounting for roughly 90% of all diabetic cases, is a serious progressive disease that results in microvascular complications (including retinopathy, neuropathy and
- nephropathy as well as macrovascular complications (including accelerated
- Sitagliptin a dipeptidyl peptidase IV inhibitor
- Sitagliptin is a new drug that increases blood levels of incretin hormones, which can increase insulin secretion, reduce glucagon secretion and have other less well characterized effects.
- sitagliptin and other dipeptidyl peptidases IV inhibitors may also influence the tissue levels of other hormones and peptides, and the long-term consequences of this broader effect have not been fully investigated.
- insulin resistance may be due to reduced numbers of cellular insulin receptors, disruption of cellular signaling pathways, or both.
- the beta cells compensate for insulin resistance by increasing insulin output.
- the beta cells become unable to produce sufficient insulin to maintain normal glucose levels (euglycemia), indicating progression to Type I I diabetes.
- fasting hyperglycemia occurs due to insulin resistance combined with beta cell dysfunction.
- beta cell defect dysfunction There are two aspects of beta cell defect dysfunction: 1 ) increased basal insulin release (occurring at low, non-stimulatory glucose concentrations), which is observed in obese, insulin-resistant pre-diabetic stages as well as in Type II diabetes, and 2) in response to a hyperglycemic challenge, a failure to increase insulin release above the already elevated basal level, which does not occur in pre-diabetic stages and may signal the transition from normo-glycemic insulin-resistant states to Type II diabetes.
- Current therapies to treat the latter aspect include inhibitors of the beta-cell ATP-sensitive potassium channel to trigger the release of endogenous insulin stores, and administration of exogenous insulin. Neither achieves accurate normalization of blood glucose levels and both carry the risk of eliciting hypoglycemia.
- agonist modulators of novel, similarly functioning, beta-cell GPCRs would also stimulate the release of endogenous insulin and promote normalization of glucose levels in Type II diabetes patients. It has also been shown that increased cAMP, for example as a result of GLP-1 stimulation, promotes beta-cell proliferation, inhibits beta- cell death and, thus, improves islet mass. This positive effect on beta-cell mass should be beneficial in Type II diabetes where insufficient insulin is produced.
- metabolic diseases have negative effects on other physiological systems and there is often co-occurrence of multiple disease states (e.g., Type I diabetes, Type II diabetes, inadequate glucose tolerance, insulin resistance, hyperglycemia, hyperlipidemia, hypertriglyceridemia, hypercholesterolemia,

First these salts are treated with an appropriate alkyl chloroformate or bis(alkyl) dicarbonate in the presence of excess base to form the corresponding alkyl carbamate.

- These catalysts may be used alone or in any combination with any of the above cyanide salts.
- ligands such as 1 , 1 '- bis(diphenylphosphino)-ferrocene (dppf) or metal additives such as zinc or copper metal.
- the reactions are carried out in polar aprotic solvents such as NMP, DMF, DMA with or without water as an additive.

- azodicarboxylates utilized. Typical conditions for this transformation are the use of DEAD with PS-PPh 3 in 1 ,4-dioxane at 22°C for 15 hours.
- An alternative to the Mitsunobu reaction for preparing compounds of Formula G is to convert the compounds of Formula F to the corresponding methanesulfonate or para-toluenesulphonate derivatives using methanesulfonyl chloride or para- toluenesulfonyl chloride, respectively, in the presence of a base such as triethylamine or pyridine.
- the intermediate sulfonate ester is then combined with a compound of general X-OH, in the presence of a base such as potassium carbonate, sodium hydride, or potassium ferf-butoxide to yield compounds of Formula G.
