BACKGROUND: Prader-Willi syndrome (PWS) is associated with hyperphagia and hyperghrelinemia with major morbidity because of obesity without effective medical treatment targeting hyperphagia. Exenatide (Byetta [synthetic Exendin-4]; AstraZeneca, Wilmington DE) is a GLP-1 receptor agonist which reduces appetite and weight and may be an effective treatment in PWS. OBJECTIVE: The objective of this study is to determine the effect of a 6-month trial of exenatide on appetite, weight and gut hormones in youth with PWS...

REVIEW
Christian Hölscher
Type 2 diabetes has been identified as a risk factor for Alzheimer's disease (AD) and Parkinson's disease (PD). In the brains of patients with AD and PD, insulin signaling is impaired. This finding has motivated new research that showed good effects using drugs that initially had been developed to treat diabetes. Preclinical studies showed good neuroprotective effects applying insulin or long lasting analogues of incretin peptides. In transgenic animal models of AD or PD, analogues of the incretin GLP-1 prevented neurodegenerative processes and improved neuronal and synaptic functionality and reduced the symptoms of the diseases...

COMPARATIVE STUDY
A J Scheen
Bydureon is a new galenic formulation (long-acting release) of exenatide, the first agonist of Glucagon-Like Peptide-1 (GLP-1) receptors having been commercialized for the management of type 2 diabetes. The microsphere technology permits a prolonged absorption of exenatide from the subcutaneous depot, which allows one injection per week instead of two injections per day with the initial formulation of exenatide (Byetta). The clinical development programme DURATION showed that exenatide 2 mg once weekly more markedly reduces glycated haemoglobin (HbA(1c)), with a similar weight loss but a better digestive tolerance profile (less nausea and vomiting after treatment initiation), compared with the twice daily 10 microg exenatide...

BACKGROUND: Glucagon-like peptide-1 (GLP-1) receptor agonists are a relatively recent addition to the treatment options for type 2 diabetes mellitus (T2DM) and are administered using prefilled pen devices. METHOD: In this open-label task and interview-based pilot study, 3 GLP-1 receptor agonist pen devices-exenatide (Byetta(®), Bristol-Myers Squibb/AstraZeneca), liraglutide (Victoza(®), Novo Nordisk), and lixisenatide (Lyxumia(®), Sanofi-Aventis)-were comparatively assessed in a randomized order in 30 participants with T2DM for ease of use, using a series of key performance measures (time taken to complete a series of tasks, number of user errors [successful performance], and user satisfaction rating)...

The renal osmoregulatory function was studied in patients with type 2 diabetes mellitus (DM). The renal response to water loading (0.7% b.w.) and simultaneous exenatide (byetta) injection (5 microg) exhibited variation and was dependent on the degree of hyperglycemia. Effective solute-free water excretion was observed in patients with well-controlled DM (HbAlc 6.0 +/- 0.1%), in which CH20 changed from -0.67 +/- 0.2 mL/min to 0.72 +/- 0.2 mL/min. This reaction was absent in patients with poorly controlled DM (HbAlc 8...

REVIEW
Konrad Talbot
The prevalence of Alzheimer's disease is increasing rapidly in the absence of truly effective therapies. A promising strategy for developing such therapies is the treatment of brain insulin resistance, a common and early feature of Alzheimer's disease, closely tied to cognitive decline and capable of promoting many biological abnormalities in the disorder. The proximal cause of brain insulin resistance appears to be neuronal elevation in the serine phosphorylation of IRS-1, most likely due to amyloid-β-triggered microglial release of proinflammatory cytokines...

Protected synthetic peptide intermediates are often hydrophobic and not soluble in most common solvents. They are thus difficult to purify by preparative reversed-phase high-performance liquid chromatography (RP-HPLC), usually used for industrial production. It is then challenging to develop alternative chromatographic purification processes. Support-free liquid-liquid chromatographic techniques, including both hydrostatic (centrifugal partition chromatography or CPC) and hydrodynamic (counter-current chromatography or CCC) devices, are mainly involved in phytochemical studies but have also been applied to synthetic peptide purification...

Paul L McCormack
Exenatide, administered subcutaneously twice daily (Byetta(®)), is a synthetic version of the natural peptide exendin-4, which is a glucagon-like peptide-1 (GLP-1) receptor agonist (incretin mimetic). Exenatide binds to the GLP-1 receptor with the same affinity as GLP-1, but has a much longer half-life, since it is not degraded by the enzyme dipeptidyl peptidase-4. Exenatide twice daily enhances glucose-dependent insulin secretion, suppresses inappropriately elevated glucagon secretion, slows gastric emptying and reduces caloric intake...

Exenatide has been widely used for the treatment of type 2 diabetes mellitus. However, its short plasma half-life of 2.4 hours has limited its clinical application. The exenatide products on the market, twice-daily Byetta™ and once-weekly Bydureon™ (both Amylin Pharmaceuticals, San Diego, CA, USA), are still not perfect. Many researchers have attempted to prolong the acting time of exenatide by preparing sustained-release dosage forms, modifying its structure, gene therapies, and other means. This review summarizes recent advances in long-acting exenatide preparations...

Peptide hormones that modulate insulin secretion have been recognized to have therapeutic potential, with peptides such as amylin (pramlintide acetate, Symlin) and exendin-4 (exenatide, Byetta) now commercially available. Preptin is a peptide that has been shown to increase insulin secretion in vitro and in vivo. Here, we describe the first chemical synthesis and analysis of a short series of preptin analogues based on the rat preptin sequence. Phe 21 in the preptin sequence was substituted with the non-protein amino acids D-Phe, D-Hphe, 3-aminobenzoic acid and 1-aminocyclooctane-1-carboxylic acid, which rendered the preptin analogues resistant to chymotryptic protease hydrolysis at this position...

Like most natural product libraries animal venoms have long been recognized as potentially rich source of biologically active molecules with the potential to be mined for the discovery of drugs, drug leads and/or biosimilars. In this work we demonstrate as a proof of concept a novel approach to explore venoms for potential biosimilarity to other drugs based on their ability to alter the transcriptomes of test cell lines followed by informatic searches and Connectivity Mapping to match the action of the venom on the cell gene expression to that of other drugs in the Connectivity Map (C-Map) database...

Exenatide effect was studied in 55 human including 38 patients with type 2 diabetes mellitus without signs of diabetic nephropathy and primary renal diseases. Preliminary study with water load in volume from 0.5 to 1% b.w. showed that water load equal to 0.7% b.w. caused significant increase in urine excretion. The rise of diuresis after 10 microg Byetta (exenatide) injection and simultaneous water load of 0.7% of b.w. depended on increase in solute-free water clearance. Thus, exenatide (mimetic of GLP-1) action let us to consider its possible role as component of osmoregulation system in human...

Glucagon-like peptide (GLP-1) increases insulin secretion but is rapidly degraded (half-life: 2 min in circulation). GLP-1 analogue, exenatide (Byetta) has a longer half-life (3.3-4 h) with potent insulinotropic effects but requires cold storage, daily abdominal injections with short shelf life. Because patients with diabetes take >60 000 injections in their life time, alternative delivery methods are highly desired. Exenatide is ideal for oral delivery because insulinotropism is glucose dependent, with reduced risk of hypoglycaemia even at higher doses...

Christian Hölscher
The current understanding of neurodegenerative processes in sporadic diseases such as Alzheimer's disease (AD), Parkinson's disease (PD) or multiple sclerosis is very limited. Several risk factors have been identified that may shed light on the underlying mechanisms that initiate the neurodegeneration. Type 2 diabetes mellitus has been identified as a risk factor for AD and PD. In AD patients, desensitization of insulin receptors in the brain has been shown, even in non-diabetic patients. Insulin acts as a growth factor in the brain and supports neuronal repair, dendritic sprouting and synaptogenesis, and protection from oxidative stress...

AIM: GLP-1(7-36)amide (GLP-1) is an intestinal hormone with effects on glucose metabolism and feeding behavior, including insulinotropic, insulinomimetic, glucagonostatic and anorectic actions. In experimental settings, GLP-1 has also been shown to diminish infarct size following heart ischemia-reperfusion. GLP-1 analogs with extended half-lives are continuously being developed against type 2 diabetes mellitus. Of these, only exendin-4 (exenatide, registered as Byetta) has been shown to mimic the infarct size-limiting effect of GLP-1 in a clinically relevant application as a postconditioning agent...
