As mentioned earlier, insulin accounts for about 50% of the worldwide market for diabetic drugs. The metabolism of carbohydrates is facilitated by insulin. Diabetes mellitus results if insulin is not properly produced in the body. Barfoed16 indicates that diabetes is the third largest cause of death after cardiovascular diseases and cancer. Petrides et al.15 indicate that insulin is a two-chain polypeptide that consists of 51 amino acids. The A chain contains 21 amino acids, and the B chain contains 30 amino acids. These chains are connected by disulfide bonds. 

There are multiple causes of diabetes. Whereas the molecular bases of some forms of diabetes are well understood, in many cases etiologies are unknown. It is customary to divide diabetes into two main forms insulin-dependent diabetes mellitus (IDDM), also referred to as Type I or juvenile-onset diabetes, and noninsulin-dependent diabetes mellitus (NIDDM), also called Type II or maturity-onset diabetes (3). 

Insulin is a peptide hormone, secreted by the pancreas, that regulates glucose metabolism in the body. Insufficient production of insulin or failure of insulin to stimulate target sites in liver, muscle, and adipose tissue leads to the serious metabolic disorder known as diabetes mellitus. Diabetes afflicts millions of people worldwide. Diabetic individuals typically exhibit high levels of glucose in the blood, but insulin injection therapy allows diabetic individuals to maintain normal levels of blood glucose.

Blood sugar (blood glucose) in human beings is controlled by the secretion of (—>) insulin by the beta (B- or (3-) cells of the islands of Langerhans in the pancreas. Loss of insulin synthesis leads to (—>) diabetes. Type 1 diabetes (insulin dependent diabetes mellitus, EDDM) begins in juveniles as an organ-specific autoimmune reaction, the destructive insulitis. 

Diabetes mellitus is defined as hyperglycaemia (fasting > 7 mM and/or 2 h postprandial >11.1 mM) due to absolute or relative lack of insulin. The most common forms are type 1 diabetes (prevalence 0.25%), with absolute lack of insulin, and type 2 diabetes (prevalence 4-6%) which is due to the combination of insulin resistance and insufficient insulin secretion.

Knockout mice have been reported for several FATPs [1]. As insulin desensitization has been closely linked to excessive fatty acid uptake and intracellular diacylgly-cerol and TG accumulation, these animal models were particularly evaluated in the context of protection from diet-induced type 2 diabetes ( Type 2 Diabetes Mellitus (T2DM)). In addition, studies on human subjects have also established genetic links between polymorphisms in FATP genes and metabolic alterations [1]. 

At present, the only available drug that stimulates glucose transport is insulin. Insulin increases the abundance of the GLUT4 in plasma membranes of adipose and muscle cells by its recruitment from intracellular storage sites (for a detailed description of its mechanism, see Chapter Diabetes Mellitus).

Disorders of lipoprotein metabolism involve perturbations which cause elevation of triglycerides and/or cholesterol, reduction of HDL-C, or alteration of properties of lipoproteins, such as their size or composition. These perturbations can be genetic (primary) or occur as a result of other diseases, conditions, or drugs (secondary). Some of the most important secondary disorders include hypothyroidism, diabetes mellitus, renal disease, and alcohol use. Hypothyroidism causes elevated LDL-C levels due primarily to downregulation of the LDL receptor. Insulin-resistance and type 2 diabetes mellitus result in impaired capacity to catabolize chylomicrons and VLDL, as well as excess hepatic triglyceride and VLDL production. Chronic kidney disease, including but not limited to end-stage...

Meglitinide contains a benzamide group. Meglitinide-related compounds such as nateglinide are non-sulfonylurea oral hypoglycemic drugs used in the treatment of type 2 (non-insulin dependent) diabetes mellitus.

Diabetes mellitus is a complicated, chronic disorder characterized by either insufficient insulin production by the beta cells of die pancreas or by cellular resistance to insulin. Insulin insufficiency results in elevated blood glucose levels, or hyperglycemia As a result of the disease, individuals with diabetes are at greater risk for a number of disorders, including myocardial infarction, cerebrovascular accident (stroke), blindness, kidney disease, and lower limb amputations. 

Insulin and the oral antidiabetic dmgi, alongwith diet and exercise are die cornerstones of treatment for diabetes mellitus. They are used to prevent episodes of hypoglycemia and to normalize carbohydrate metabolism.

Those with type 1 diabetes mellitus produce insulin in insufficient amounts and tiierefore must have insulin supplementation to survive Type 1 diabetes usually has a rapid onset, occurs before die age of 20 years, produces more severe symptoms tiian type 2 diabetes, and is more difficult to control. Major symptoms of type 1 diabetes include hyperglycemia, polydipsia (increased thirst), polyphagia (increased appetite), polyuria (increased urination), and weight loss. Treatment of type 1 diabetes is particularly difficult to control because of the lack of insulin production by die pancreas. Treatment requires a strict regimen tiiat typically includes a carefully calculated diet, planned physical activity, home glucose testing several times a day, and multiple daily insulin injections. 

Type 2 diabetes mellitus affects about 90% to 95% of individuals witii diabetes. Those with type 2 diabetes mellitus eitiier have a decreased production of insulin...
