Technical background
Diabetes are a kind of global prevalence diseases, are grape absolutely or caused by relative deficiency due to internal insulin
Syndrome (present Research Guangdong Pharmaceutical University of Chen Ruijie Remedies for diabetes of sugar, protein, disorders of lipid metabolism
Report, 2001,7 (2): 131-133), I type and type II diabetes (Type2diabetes can be divided into according to pathogenesis
Mellitus, T2DM, similarly hereinafter).In all diabetics made a definite diagnosis, patient 90-95% suffers from T2DM, and patient is often
Along with fat, physical activity deficiency (physical inactivity), older, family's diabetic history, glucose metabolism
Damage and have family's diabetic history etc..T2DM is also a kind of progressive disease (progressive disease).2000,
There are about 1.71 hundred million people to suffer from diabetes in World Health Organization's statistical data estimation whole world;2005, U.S.'s disease control and prevention
There are about 0.208 hundred million Americans to suffer from diabetes for center (Centers for Disease compares and Prevention) estimation, about
Account for the 7% of U.S. population;It is counted according to International Diabetes Federation within 2006, global diabetes number of patients, which is about 2.46 hundred million, (to be accounted for about complete
The 5.9% of ball total population) and 46% patient age between 40-59 years old.Studies have shown that normal person and T2DM patient are to grape
Sugar reaction has very important difference.Normal person belongs to early stage insulin response (early to the reaction of blood glucose rise after the meal
Insulin response).
T2DM feature is that insulin inhibits and pancreas Instreptozotocin Induced damages, and leads to insulin deficit and hyperglycemia
(Ferrannini E.Insulin resistance versus insulin deficiency in non-insulin-
dependent diabetes mellitus:problems and prospects.Endocr Rev.1998,19(4):477–
490).Patient T2DM generally will appear after meal and hyperglycemia (fasting blood-glucose > 125mg/dL), and hyperglycemia is mainly
As pancreas beta cell cannot secrete enough insulin compensate the insulin in perienchyma inhibit caused by (Weyer
C.,Bogardus C.,Mott DM.,et al.The natural history of insulin secretory
dysfunction and insulin resistance in the pathogenesis of type2diabetes
Mellitus.J.Clin.Invest.1999,104 (6): 787-794).
The Major Risk Factors of T2DM are obesities, it has very big harm to human health.Patient suffers from angiocarpy
The danger of disease and unusual death can become larger, at the same T2DM often with some other high risk diseases, such as hypertension, blood lipid
Obstacle and obesity etc. exist simultaneously;60% patient T2DM includes retinopathy along with microvascular complication person
(retinopathy) and neuropathy (neuropathy) and cardiovascular pathologies (cardiovascular related with T2DM
Morbidities) such as coronary heart disease, myocardial infarction and shock.In the U.S., cardiovascular disease
(cardiovascular disease, CVD) is to lead to morbidity and dead principal element, and type-2 diabetes mellitus is big blood vessel
(macrovascular) complication such as atherosclerosis (atherosclerosis), myocardial infarction (myocardial
Infarction), the Major Risk Factors (major risk factor) of the generation of shock and peripheral vascular disease.Suffer from diabetes
The adult heart disease and shock of occurring cause dead probability to be 2-4 times of non-diabetes patient, in addition, close to 65% diabetes
People dies of heart disease and shock.
Other than the injury to patient's physiology and body, T2DM can also cause very big financial burden to society, according to system
Meter, is used to treat about 22,900,000,000 dollars of expense of diabetic complication every year in the U.S., annual for T2DM and its complication
For total cost close to 57,100,000,000 dollars, out-of-pocket cost total value is more than 8,000,000,000 dollars.
T2DM therapeutic agent is always focus concerned by people, from the sulphonyl class of early stage, biguanides oral hypoglycemic drug to
Recent insulin sensitizer and alpha-glucosidase inhibitor, from animal insulin to actrapid monotard and the exploitation of various novel forms,
From the drug therapy mechanism of simple increase insulin to the new way for acting on generation insulin earlier.Weight gain is
Common adverse reaction after this kind of oral or injection antidiabetic drug medication, this point may be decreased compliance, and can increase hair
The risk of raw cardiovascular disease.Therefore develop highly-safe, patient's biddability is good, the low novel T2DM therapeutic agent of adverse reaction at
Fall over each other the hot spot developed for numerous research institutions and pharmacy corporation.
Before more than 100 years, Moore just proposes that duodenum can be secreted " the chemical excitant " of stimulating pancreas secretion, and
Attempt to inject enteron aisle extract to treat diabetes.The humoral factor for being subsequently found intestinal secretion can enhance the endocrine function of pancreas
Can, no matter the insulin secretion that vein or oral glucose are caused, the stimulation of about 50% peptides caused by the enteron aisle makees
With Zunz and Labarre proposes the concept of " duodenin (incretin) " thus.So far separated 2 kinds of intestines out are hypoglycemic
Element, i.e. glucose dependent insulin release peptide (glucose-dependent insulinotropic polypeptide,
) and glucagon-like-peptide-1 (glucagon-like peptide-1, GLP-1) GIP.GIP and GLP-1 is inhaled in nutrition
Time receiving is secreted by specific enteric nervous secretory cell, and wherein GIP is by duodenum and neighbouring jejunum K cell (proximal
Jejunal K cells) it secretes, GLP-1 is then synthesized in L cell and is primarily present in distal small bowel and colon (Drucker
DJ.Enhancing incretin action for the treatment of type2diabetes.Diabetes
Care.2003,26 (10): 2929-2940).
GLP-1 exists in blood plasma with two kinds of biologically active forms of GLP-1 (7-37) and GLP-1 (7-36) amide, this two
A polypeptide only has an amino acid of differences, and they biological effect and Half-life in vivo be identical (Drucker
DJ.Enhancing incretin action for the treatment of type2diabetes.Diabetes
Care.2003,26 (10): 2929-2940).
Usually said GLP-1 is the general designation to GLP-1 (7-37) and GLP-1 (7-36) amide.GIP and GLP-1 are in stomach
Enteron aisle can be degraded by intracorporal dipeptidyl peptidase-IV (dipeptidyl peptidase-IV, DPP-IV) quickly when releasing
For inactive form, thus make the half-life period of GIP and GLP-1 in vivo it is very low (GIP Half-life in vivo about 5-7 minutes,
GLP-1 Half-life in vivo about 2 minutes) (Drucker DJ.Enhancing incretin action for the
Treatment of type2diabetes.Diabetes Care.2003,26 (10): 2929-2940).Studies have shown that mostly
Number degradation processes occur to occur when GIP and GLP-1 enters blood vessel containing DPP-IV, the GLP-1 not being degraded on a small quantity and
GIP can enter pancreas and with its binding site combine and stimulate beta cell release insulin.With sulfonylureas (sulfonylureas)
Insulin mechanism difference is discharged by directly facilitating function beta cell, it is all dependence on the glucose that incretin effect is most of
Type.In addition, some animals and human vitronectin are experiments have shown that also there are GLP-1 A cells to inhibit and reduce glucagon excessively to divide
The effects of secreting (glucagon hypersecretion).
Although T2DM patient's body blood plasma GIP level is normal but the effect of its incretin is remarkably decreased or loses, and
GLP-1 is then to reduce, therefore study the drug based on GLP-1 and be more conducive to treatment T2DM in T2DM patient's body level.Although
GLP-1 (7-37) and GLP-1 (7-36) amide level can improve in a few minutes after meal, and GLP-1 (7-36) amide content is more
A bit, thus endocrine and nerve signal transmitting double action may the food being digested from alimentary canal lower end enter small intestine and
The secretion of GLP-1 has been substantially increased before colon.GLP-1 level is very low (about 5-10pmol/ in blood plasma under fasting state
L), and its level increases sharply and (reaches 15-50pmol/L) after feed.In the case where DPP-IV and kidney remove double action, in vivo
The GLP-1 level of circulation reduces rapidly, and other enzymes such as human body neutral endopeptidase 24.11(human neutral
) etc. endopeptidase2411 also whether the research work for having lost conclusive effect active to GLP-1 is carrying out
In.Since GLP-1 is the good substrate that alanine is DPP-IV in 2 amino acids, it is easier to be degraded to inactive peptide fragment.
In fact, the main reason for DPP-IV is only incretin loss of activity in vivo, experiment shows what DPP-IV gene was silenced
GLP-1 level significantly improves in Mice Body, increases the secretion of insulin.Exactly under DPP-IV effect, complete in vivo and tool
The GLP-1 for having bioactivity is only 10-20%(Deacon CF, the Nauck MA, Toft- of blood plasma GLP-1 total content
Nielsen M,et al.Both subcutaneously and intravenously administered glucagon-
like peptide1are rapidly degraded from the NH2-terminus in type2-diabetic
Patients and in healthy subjects.Diabetes.1995,44 (9): 1126-1131).
GLP-1 and GIP passes through the G- G-protein linked receptor (G-protein-coupled entirely different with structure
Receptors, GPCRs) in conjunction with and play each self-applying.GIP receptor is expressed by pancreaticβ-cell, and small part is in rouge
Fat tissue and central nervous system expression.In contrast, GLP-1 receptor is then mainly in pancreatic islet alpha-and beta cell and periphery group
It knits including being expressed in maincenter and peripheral nervous system, brain, kidney, lung and gastrointestinal tract etc..Two incretin are in beta cell
Activation will lead to increasing sharply for cAMP and intracellular calcium levels, so as to cause its with glucose-dependent manner to exocytosis, hold
Continuous incretin receptor signal transmitting will lead to genetic transcription, the biosynthesis for increasing insulin with protein kinase A correlation
And stimulate proliferation (the Gallwitz B.Glucagon-like peptide-1-based therapies for of beta cell
The treatment of type2diabetes mellitus.Treat Endocrinol.2005,4 (6): 361-370).
The activation of GLP-1 and GIP receptor can also inhibit beta cell apoptosis in rodent and Human islet while increase its survival
Rate (Li Y, Hansotia T, Yusta B, et al.Glucagon-like peptide-1receptor signaling
Modulates beta cell apoptosis.J Biol Chem.2003,278 (1): 471-478).With GLP-1 by body surface
Up to it is consistent be GLP-1 can also be secreted with glucagon suppression, gastric emptying and food intake, while passing through neuromechanism
(neural mechanism) enhances the degradation to glucose.It should be noted that react identical with other insulin secretions,
GLP-1 is glucagon dependence to the effect of glucose production, and causes counter regulation to discharge since hypoglycemia acts on
(counter-regulatory release of glucagon) though glucagon act in GLP-1 pharmacological concentrations
Under be still fully retained.
Endogenous GLP-1 and GIP is short of money in receptor for the important physiological role played in glucose homeostasis
It is had made intensive studies in anti-agent or knock out mice.The antagonism of acute GLP-1 or GIP reduces rodent body
The secretion of interior insulin and increase Plasma glucose level.Equally, GIP or GLP-1 receptor deactivation mutant mice equally has
The secretion of deficiency glucose stimulated insulin and damaging glucose tolerance.GLP-1 also has fasting blood-glucose regulatory function, because
It will lead to the raising of rodent fasting glucose level for the acute antagonism or genetic disruption of GLP-1 effect;Meanwhile GLP-
1 is the basis that glucose controls in human body, to antagonism Exendin's (9-39) research shows that GLP-1 effect can make after being destroyed
At defective glucose stimulated insulin secretion (defective glucose-stimulated insulin secretion),
Glucose clearance is reduced, Plasma Glucagon Level is increased and accelerates gastric emptying.In addition, the physiological action of GLP-1
(Deacon CF.Therapeutic strategies based on glucagon-like
Peptide1.Diabetes.2004,53 (9): 2181-2189) further include: (1) help tissue blood glucose absorb, mediating glucose according to
Rely type insulin secretion;(2) inhibit postprandial glucagon secretion, reduce glycogen release;(3) gastric emptying is adjusted, prevents food from existing
The excessive circulation of glucose when intestinal absorption;(4) food intake (such as appetite) is inhibited.Furthermore animal experiment also shows the one of GLP-1
A physiological role is pancreas beta cell quantity in liptinite.
Because GLP-1 and GIP is many-sided with good action in control blood glucose etc., especially it does not generate hypoglycemia and prolongs
The characteristics of slow gastric emptying control weight, causes the interest of numerous scientists.People begin trying research based on GLP-1 and GIP medicine
Object is for treating T2DM.It is well known that patient T2DM lacks or loses incretin effect, one reason for this is that T2DM
The incretin effect of GIP weakens significantly in patient body;Meanwhile T2DM patient's body GLP-1 level is very low, and because diet pierces
Swash the GLP-1 level generated and substantially reduces (Toft-Nielsen MB, Damholt MB, Madsbad S, et
al.Determinants of the impaired secretion of glucagon-like peptide-1in
Type2diabetic patients.J Clin Endocrinol Metab.2001,86 (8): 3717-3723).Because of T2DM
Patient's body GLP-1 acts on having obtained part reservation, it is intended to enhance the drug research of T2DM patient's body incretin effect
One of direction is exactly GLP-1 synergist.
GLP-1 analog can stimulate internal pancreas islet as endogenous GLP or GIP in a manner of dependence on the glucose type
The secretion of element, while the internal release of glucagon suppression.Furthermore GLP-1 analog has effect to following symptom: (1) low
Blood glucose.Different from other rush secretion drug, GLP-1 analog is due to promoting internal insulin point with a kind of glucose-dependent manner
It secretes, therefore its hypoglycemic effect has self limiting, and serious hypoglycemia will not be generally caused in large dosage.In spite of document report
Accuse GLP-1 and blood glucose can be reduced to normal level hereinafter, but the effect it is of short duration, and be considered as GLP-1 pancreotropic hormone point
Secrete the natural result of effect.Since the inactivation of insulin needs certain time, reduced when because of blood sugar concentration, the thorn of GLP-1
When swashing declines without neo-insulin secretion, original insulin is still in action.In short, GLP-1 can make blood
Sugar is temporarily reduced under normal level, but not causes serious and lasting hypoglycemia.(2) to being satiated with food and the effect of weight.It removes
It directly reduces except blood glucose, GLP-1 can also reduce the intake of food, this is all obtained on rodent and the person
Verifying.In this way blood glucose level can be indirectly controlled by losing weight.GLP-1 inhibits gastrin and feed stimulation there are also potential
Gastric acid secretion effect, these effects show that GLP-1 may also have the function of prevention of digestive tract ulcers.The effect of GLP-1
Mechanism makes it that can not only become ideal diabetes B, can also become the therapeutic agent of obese diabetic patient.GLP-
1 can be enhanced the satietion of patient, reduces food intake and keep weight or weight-reducing;(3) beta cell health is maintained.Some researchs
Prompt GLP-1 can prevent by the conversion of impaired glucose tolerance to diabetes, and there are also some reported literatures GLP-1 class compounds pair
The growth of experimental animal beta Cell of islet and proliferation have direct effect, and have experiment discovery GLP-1 that can promote pancreatic stem
Differentiation of the cell to functional beta cells.These results imply that GLP-1 has the function of protecting pancreas islet and delays diabetes development,
The form and function of beta cell can be kept, while reducing its apoptosis;(4) to the effect of postprandial hyperglycemia.This phenomenon represents
A kind of new direction of T2DM treatment.Since some oral drugs and exogenous insulin cannot inhibit or reduce the high blood of T2DM patient's pancreas
Sugared element crosses hypersecretion, and GLP-1 analog can may be discharged by direct glucagon suppression or because promoting insulin point
Secrete and the paracrine inhibiting effect that generates and glucagon hypersecretion is had an impact.Can effectively it be subtracted by the two mechanism
Few postprandial hyperglycemia phenomenon;Meanwhile keeping Instreptozotocin Induced that there may also be effect to long-term control postprandial hyperglycemia.
GLP-1 analog is taken by subcutaneous injection simultaneously, and the amount for not needing to calculate carbon water compound is best to estimate
Drug dose, do not need yet to blood glucose carry out self monitor, keep the use of this kind of drug more more convenient than insulin.
The treatment for turning out to be diabetes B of natural GLP-1 multiple efficacies brings new hope, and still, human body is natural
GLP-1 is very unstable, can be degraded by DPP IV (DPP-IV), half-life period is only 1~2 minute.According to natural GLP-1
Blood glucose is reduced, needs Intravenous Infusion or continuous subcutaneous infusion, Clinical feasibility is poor.Faced with this situation, people are continuous
It explores, it would be desirable to find the method for extending GLP-1 action time.Therefore long-acting GLP-1 analog or derivatives thereof is developed, at
For the key areas of the world of medicine's concern.
Exenatide is the Exendin-4 of synthesis, is developed cooperatively by Li Lai company and Amylin company, trade nameFDA and EMEA has been approved by its listing, for treating T2DM.It has 50% with mammal GLP-1 in sequence
Homology and its (Drucker DJ, Nauck MA.The incretin similar with GLP-1 to the affine site of GLP-1 receptor

Concentration continues to increase Exenatide in vivo afterwards, maximum concentration can be reached in blood plasma within 2 hours or so, can maintain 4-6 hours
(Nielsen LL, Baron AD.Pharmacology of exenatide (synthetic exendin-4) for the
Treatment of type2diabetes.Curr Opin Investig Drugs.2003,4 (4): 401-05).It needs to infuse
Meaning is that the metabolism of Exenatide does not occur in liver, and mainly through proteasome degradation after glomerular filtration.
Exenatide have special glucose modulatory activities, including dependence on the glucose type enhancing insulin secretion effect,
The effects of dependence on the glucose type inhibits incorrect excessively high glucagon secretion effect, slows down gastric emptying and reduce food intake.
To the research of internal and external diabetes model, it has also been found that, Exenatide also has storage first stage (first-phase) pancreas islet
Element secretion promotes beta-cell proliferation and insulin from the regenerated effect of its precursor.
In order to reach preferable glycemic control, double injection Exenatide is needed daily, this brings very big to patient
It is inconvenient.Furthermore also there is Exenatide slight extremely medium gastric disorder causing nausea (about 40% patient has this reaction), diarrhea and vomiting (to be less than
15% patient has both reactions);About 50% can generate antibody in the patient of Exenatide treatment, although these antibody are not
It will affect drug effect or cause other clinical effects.After taking Byetta bleeding or necrotizing pancreatitis occur for discovery 6 again recently
