Alrestatin is an inhibitor of aldose reductase, an enzyme involved in the pathogenesis of complications of diabetes mellitus, including diabetic neuropathy. [1] [2]

Contents

Alrestat was first synthesized in 1969 and was the first aldose reductase inhibitor (ARI) with oral bioavailability to undergo clinical trials, in the late 1970s and early 1980s. Low-quality trials and a high incidence of adverse effects (particularly hepatotoxicity) led to termination of its development, and it was never in clinical use. [3] [4] It is structurally related to tolrestat, another ARI that was briefly marketed before being withdrawn in 1997.

Synthesis

Alrestatin can be synthesized by the reaction of naphthalic anhydride with glycine. [5]

Aldose reductase inhibitors are a class of drugs being studied as a way to prevent eye and nerve damage in people with diabetes.

Diabetic neuropathy is various types of nerve damage associated with diabetes mellitus. Symptoms depend on the site of nerve damage and can include motor changes such as weakness; sensory symptoms such as numbness, tingling, or pain; or autonomic changes such as urinary symptoms. These changes are thought to result from a microvascular injury involving small blood vessels that supply nerves. Relatively common conditions which may be associated with diabetic neuropathy include distal symmetric polyneuropathy; third, fourth, or sixth cranial nerve palsy; mononeuropathy; mononeuropathy multiplex; diabetic amyotrophy; and autonomic neuropathy.

Diabetic angiopathy is a form of angiopathy associated with diabetic complications. While not exclusive, the two most common forms are diabetic retinopathy and diabetic nephropathy, whose pathophysiologies are largely identical. Other forms of diabetic angiopathy include diabetic neuropathy and diabetic cardiomyopathy.

The polyol pathway is a two-step process that converts glucose to fructose. In this pathway glucose is reduced to sorbitol, which is subsequently oxidized to fructose. It is also called the sorbitol-aldose reductase pathway.

<span class="mw-page-title-main">Aldose reductase</span> Enzyme

In enzymology, aldose reductase is a cytosolic NADPH-dependent oxidoreductase that catalyzes the reduction of a variety of aldehydes and carbonyls, including monosaccharides. It is primarily known for catalyzing the reduction of glucose to sorbitol, the first step in polyol pathway of glucose metabolism.

<span class="mw-page-title-main">Epalrestat</span> Chemical compound

Epalrestat is a carboxylic acid derivative and a noncompetitive and reversible aldose reductase inhibitor used for the treatment of diabetic neuropathy, which is one of the most common long-term complications in patients with diabetes mellitus. It reduces the accumulation of intracellular sorbitol which is believed to be the cause of diabetic neuropathy, retinopathy and nephropathy It is well tolerated, with the most commonly reported adverse effects being gastrointestinal issues such as nausea and vomiting, as well as increases in certain liver enzymes. Chemically, epalrestat is unusual in that it is a drug that contains a rhodanine group. Aldose reductase is the key enzyme in the polyol pathway whose enhanced activity is the basis of diabetic neuropathy. Aldose reductase inhibitors (ARI) target this enzyme. Out of the many ARIs developed, ranirestat and fidarestat are in the trial stage. Others have been discarded due to unacceptable adverse effects or weak efficacy. Epalrestat is the only ARI commercially available. It is easily absorbed into the neural tissue and inhibits the enzyme with minimum side effects.

Aldo-keto reductase family 1, member B1 (AKR1B1), also known as aldose reductase, is an enzyme that is encoded by the AKR1B1 gene in humans. It is a reduced nicotinamide-adenine dinucleotide phosphate (NADPH)-dependent enzyme catalyzing the reduction of various aldehydes and ketones to the corresponding alcohol. The involvement of AKR1B1 in oxidative stress diseases, cell signal transduction, and cell proliferation process endows AKR1B1 with potential as a therapeutic target.

Alcohol dehydrogenase [NADP+] also known as aldehyde reductase or aldo-keto reductase family 1 member A1 is an enzyme that in humans is encoded by the AKR1A1 gene. AKR1A1 belongs to the aldo-keto reductase (AKR) superfamily. It catalyzes the NADPH-dependent reduction of a variety of aromatic and aliphatic aldehydes to their corresponding alcohols and catalyzes the reduction of mevaldate to mevalonic acid and of glyceraldehyde to glycerol. Mutations in the AKR1A1 gene has been found associated with non-Hodgkin's lymphoma.

<span class="mw-page-title-main">Diabetic cardiomyopathy</span> Medical condition

Diabetic cardiomyopathy is a disorder of the heart muscle in people with diabetes. It can lead to inability of the heart to circulate blood through the body effectively, a state known as heart failure(HF), with accumulation of fluid in the lungs or legs. Most heart failure in people with diabetes results from coronary artery disease, and diabetic cardiomyopathy is only said to exist if there is no coronary artery disease to explain the heart muscle disorder.

<span class="mw-page-title-main">Aldo-keto reductase</span>

The aldo-keto reductase family is a family of proteins that are subdivided into 16 categories; these include a number of related monomeric NADPH-dependent oxidoreductases, such as aldehyde reductase, aldose reductase, prostaglandin F synthase, xylose reductase, rho crystallin, and many others.

Complications of diabetes are secondary diseases that are a result of elevated blood glucose levels that occur in diabetic patients. These complications can be divided into two types: acute and chronic. Acute complications are complications that develop rapidly and can be exemplified as diabetic ketoacidosis (DKA), hyperglycemic hyperosmolar state (HHS), lactic acidosis (LA), and hypoglycemia. Chronic complications develop over time and are generally classified in two categories: microvascular and macrovascular. Microvascular complications include neuropathy, nephropathy, and retinopathy; while cardiovascular disease, stroke, and peripheral vascular disease are included in the macrovascular complications.

Sorbinil (INN) is an aldose reductase inhibitor being investigated for treatment of diabetic complications including neuropathy and retinopathy. Aldose reductase is an enzyme present in lens and brain that removes excess glucose by converting it to sorbitol. Sorbitol accumulation can lead to the development of cataracts in the lens and neuropathy in peripheral nerves. Sorbinil has been shown to inhibit aldose reductase in human brain and placenta and calf and rat lens. Sorbinil reduced sorbitol accumulation in rat lens and sciatic nerve of diabetic rats orally administered 0.25 mg/kg sorbinil.
