Description
Technical field
The present invention relates to the fields of ROCK inhibitor.In particular it relates to it generates treatment to inhibiting ROCK and makees
The ROCK inhibitor of a kind of analog derivative of thiophene-carboxamides containing alcoxyl, its preparation method and preparing treatment sexual function barrier
Hinder the purposes waited in disease medicaments.
Background technology
Serine/threonine protein kitase ROCK is made of in human body two kinds of hypotype ROCK I and ROCK II.ROCK I
It is encoded in No. 18 chromosomes, and ROCK II (also referred to as Rho kinases) are then located at No. 12 chromosomes.The molecular mass of the two
It is each about 160kD.The two (amino acid sequence) has 65% homology, and the homology in wherein kinases area is up to 95%.To the greatest extent
It is much like to manage their sequence, but Tissue distribution is had nothing in common with each other.The expression of ROCK I highest levels can be from heart, lung and bone
Structure observation arrives, and ROCK II are then mainly expressed in brain.Nearest data show that both isomers have the function of part rich
Yu Xing, ROCK I are more related in immunocompetence, and ROCK II are then related in smooth muscle function.
ROCK activity has been demonstrated one member-GTPase RhoA institutes shadow by Rho (Ras homologues) gtp binding protein
It rings and enhances.The RhoA of active form GTP reference states and the ROCK Rho protein binding domains (RBD) positioned at inhibition carboxyl terminal ring certainly
Generate interaction.After bonding, the interaction between ROCK negativity regulatory region and kinases area is destroyed.This process causes
Kinases obtains the opening conformation for being completely in activated state.The opening conformation is also by lipid activity factor (such as arachidonic acid)
And caused by the combination of the PH structural domains of kinases carboxy-terminal domains.Also illustrate another activation machine in apoptosis process
System, and it is related to ROCK I and II are carried out respectively through Caspase (caspase) -3 and -2 (or granzyme granzyme B)
C-terminus cracks.
ROCK plays an important role in various cell functions, such as smooth muscle contraction, the group of actin cytoskeleton
Knit, platelet activation, the downward of myosin phosphatase cell adherence, the migration of aortic smooth muscle cell, hyperplasia, survival and
Thrombin induction reaction, cardiac myocyte hypertrophy, bronchial smooth muscle contraction, smooth muscle contraction and the restructuring of nonmuscle cells skeleton,
Capacity regulates and controls activation, neural process retraction, wound healing, cell transformation and the gene expression of anion channel.ROCK is also being related to
It plays a role in many signal pathways of autoimmunity and aspect of inflammation.ROCK has been demonstrated to play in terms of the activation of NF- κ B
Effect, the NF- κ B are a kind of key molecules for causing Tumor necrosis factor TNF and the generation of other inflammatory cytokines.It was reported that
ROCK inhibitor, which can resist lipopolysaccharides (LPS), stimulates the generation of TNF-α and the IL-6 factors in THP-1 macrophages.Therefore, ROCK
Inhibitor provides beneficial therapy to treat autoimmune disease, diseases associated with inflammation and response to oxidative stress.
Generally speaking, ROCK is the major control point of smooth muscle cell function, and is the inflammation mistake of various inflammatory cells
The crucial signaling ingredient of the fibrosis and remodeling process of journey and many affected organs.There is apparent sign to show that ROCK is related to
The pathogenesis of many diseases includes asthma, chronic obstructive pulmonary disease and glaucoma in the middle.In addition, ROCK involve it is various
Disease and obstacle include eye illness, breathing problem, angiocardiopathy and vascular diseases, diseases associated with inflammation, nervous system in the middle
With central nervous system disease, proliferative disease, kidney trouble, sex dysfunction, disease in the blood system, skeletal diseases, glycosuria
Disease, benign prostate hyperplasia, graft-rejection, liver diseases, systemic loupus erythematosus, spasm, hypertension, chronic obstruction
Property bladder disease, premature labor, infection, allergy, obesity, pancreatic disease and AIDS.
With gene knockout model and substantial amounts of academic research illustratively, ROCK looks like the target spot of a safety.This
The data of a little knock out mice and the post-market surveillance research of Fasudil (Fasudil) (go out for treating cavum subarachnoidale
The strong ROCK inhibitor of appropriateness of cerebral angiospasm after blood) it combines, it is a real and significant medicine target to show ROCK
Mark.ROCK inhibitor can be used as the curative drug that treatment is related to the obstacle of ROCK approach.Therefore, we extremely need exploitation one
Kind can be used for treating the relevant ROCK inhibitor of various and ROCK activation, be especially considering that most of these current diseases are all controlled
Treat deficiency.Some unrestricted examples are glaucoma, asthma and chronic obstructive pulmonary disease.
Glaucoma, one kind may result in the disease of hypopsia and blindness due to optic nerve injury, be because of intraocular pressure
Caused by increase.This is the common cause of adult's blindness, is a kind of chronic disease for needing to control all the life after making a definite diagnosis mostly.
Due to current treatment can only control and can not radical curing of disease, and further by stimulate, side effect locally and systemically, the disease
Disease needs the cure of an improvement.In addition, other positive influences, that is, ROCK inhibitor anti-inflammatory and nerve regneration into
Dividing will be prioritized.The ROCK inhibitor of reference such as Y-27632 can change cellular morphology and the TM mankind of reduction incubation are thin
Tonofibrils, Focal adhesions and the MLC phosphorylations of born of the same parents;The human trabecular meshwork shape tissue of their diastole in vitro cultures, diastole are external
Mankind's Schlemm pipeline endothelial cells will dramatically increase girder outflow when being applied topically to animal, cause advantageously to drop
Low intraocular pressure.
Allergic asthma is a kind of to be immunized instead because heredity susceptible person generates non-habitual to ubiquitous environment albumen
Should, so as to the respiratory tract chronic inflammatory diseases triggered.Although there is the therapy of successful, illness rate because these therapies without
Method is effected a radical cure and increased;Present situation is still being aggravated, and has more and more nonresponders.It can do with all factors of the disease
New, efficient, steroid-sparing be required.
Chronic obstructive pulmonary disease (Chronic Obstructive Pulmonary Disease, COPD) is one group with slow
Property irreversibility respiratory tract is restricted, is characterized with abnormal inflammatory reaction, the remodeling and damage of bronchoconstriction and lung tissue
Disease.One of the main reason for it is human death, illness rate just steadily increase.Since current therapy is not enough to cure disease
Disease, we seek new therapy at urgent need.Due to glucocorticoid only play an important role of it is limited or absolutely void, because
Bronchodilator is used only in this till now.Quote the separated people's branch gas of ROCK inhibitor energy diastole of such as Y-27632
Pipe prepared product, inhibiting the resistance of respiratory tract of anesthetized animal increases, and the outer diastole in vivo beta-receptor agonist of intensive aspect acts on,
And rapid bronchiectasis is given after inhalation.In addition, ROCK inhibitor can block H2O2The tracheal smooth muscle of induction is shunk
(clinical marker of response to oxidative stress).
Relevant with respiratory inflammation to be, ROCK inhibitor can resist the increasing across endothelial cell permeability of antiphlogistic mediation
By force, the barrier integrity of blood vessel endothelium is kept, inhibits the inflow of the eosinophil after internal ovalbumin excites, prevent lung
The formation of oedema and neutrophil migration inhibit anti-to the allergy of methacholine and serotonin in allergy Respiratory Tract of Mice
It should and block tumor necrosis factor (TNF) release of LPS inductions.In terms of respiratory tract fibrosis and remodeling, ROCK inhibitor
The migration that asm cell can be blocked to induce.ROCK is found in the mankind's for the external evidence that Airway Remodeling acts on
Lung cancer cell line, the airway smooth muscle cells of calf and human airway smooth muscle.ROCK is for the internal card of Fibrosis parameters
According to generally resulting from mouse (myocardial fibrosis that wherein excalation of ROCK causes attenuation).Y-27632 obstructs for cardiac muscle
Plug and Fasudil (fasudil) are decayed for the myocardial fibrosis of the congestive heart failure of chronic hypertension rat model
Other indication is brought for the importance of remodeling for ROCK.Finally, the apoptosis of ROCK inhibitor increase smooth muscle cell is thin
Born of the same parents lose.
The human sexual response of male and female can generate due to the interaction of physiology, psychology and Hormone Factors.Male and
One of them of female body reaction is common that blood vessel function response, it can be loose because of the vascular smooth muscle that sexual stimulus is brought
It relaxes, so as to making phallic property tissue congested.Therefore, when the smooth muscle of perineum blood vessel loosens, the blood pressure in penis and clitoris
It is consequently increased with blood flow.The inflow of arterial blood will cause penis or corpora cavernosa clitoridis to expand, so as to cause erection.Impotence
(male erectile dysfunction) is generally defined as being unable to reach and maintains to carry out the erectile ability for being satisfied with sex expression and sexual intercourse enough.
Impotence may be because mental handicape, nervous system abnormality or other include the physiological barrier or many reasons of anhormonia
With reference to causing.In the U.S., impotence estimation influences 40% 40 years old male, will be improved by 50 years old with age
To about 50%, by 70 years old when will be up to 67%.Women can also face sex dysfunction with the increase at age, and with climacteric
Breaking-out and the risk for increasing vascular diseases.Therefore, as male, the sexual arousal of women is at least part of can be with making clitoris
Congested blood flow increases.The blood flow of vagina also increases the degree of lubrication of vagina.Therefore, Female sexual dysfunction may be
Caused by being unable to reach or maintaining clitoral engorgement and/or vaginal lubrication in entire sexuality period.At present, it is most of to use
The signal transduction pathway for reducing calcium ion can be targeted in the vasodilator for the treatment of erectile dysfunction, this needs startup blood vessel to put down
The contraction movement of sliding flesh.However, from the point of view of physiological angle, vasoconstrictive startup is a very acute activity, when continuing
Between only from the several seconds to several minutes.Erectile tissue is maintained at by the long-term vessel retraction of calcium dependent/non-dependent signal transduction pathway
Relaxed state.It is RhoA/Rho kinase pathways to keep the vasoconstrictive signal pathway of calcium dependent/non-dependent.ROCK inhibitor is for controlling
It is also corresponding useful to treat erectile dysfunction.Therefore, from the point of view of on the one hand, the present invention is used to treat male or female comprising a kind of
The method of dysfunction, including including and weakening in organ subject to sexual stimulus to individuals in need local application
Rho kinase activities compound.
There are several known ROCK inhibitor types at present.Current emphasis is the application of tumour and angiocardiopathy.It arrives
Until now, the outstanding treatment potentiality of ROCK inhibitor is only limited in limited scope.Its reason is that ROCK is such a
Effectively with extensive biochemical regulator, the systemic inhibitory action of ROCK can bring powerful biological effect, but be also regarded as
The side effect of most of disease treatments.In fact, ROCK inhibitor is subject to the medical application of stronger anti-inflammatory component treatment disease
ROCK key effects adjust smooth muscle cell contraction nourish the stage when obstruction.The ROCK inhibitor of systemic applications can lure
Hair blood pressure is decreased obviously.Therefore, we have ROCK inhibitor of different nature high demand.
In order to specifically be treated by the specific aim for adjusting smooth muscle function and/or inflammatory process and/or remodeling expansion disease,
We can target target organ at high expectations ROCK inhibitor, enter other organs to avoid the drug of big deal.Therefore, it is local
Or local medicinal application is desired.Under normal conditions, the drug of topical application is used to treat respiratory tract, eyes, property work(
It can obstacle and dermatopathy.
To sum up, we still have lasting necessary design and exploitation ROCK inhibitor at present, it is wide for therapeutic domain
