Description
Background of invention
A) invention field
The present invention relates to novel Rat parathyroid hormone 1-34 and the analogue of parathyroid hormone-related peptide, their solid phase synthesis and recombinant technology and they increase the purposes of sclerotin in Mammals.
B) description of correlative technology field
Osteoporosis is modal metabolic bone disease form, and can think Symptomatic, the fracture stage of bone forfeiture (osteopenia).Occur although osteoporosis can be secondary to many primary diseases, 90% case is idiopathic.Postmenopausal women especially easy idiopathic osteoporosis (after the menopause or I type osteoporosis).The height morbidity group of another spontaneous osteoporosis is people at advanced age (sex) (a senile or II type osteoporosis).Find that osteoporosis is relevant with following situation: use reflunomide, immobilization or CBR, excessive drinking, diabetes, to the chemotherapy of sexual gland virose (go-nadotoxic), blood prolactin too much, anorexia nervosa, primary and secondary amenorrhea and oophorectomize.
In various forms of osteoporosis, often to fracture, this is that the bone forfeiture reaches the result that the depleted point of mechanicalness is caused.The feature of post-menopausal osteoporosis is the fracture of wrist and backbone, and the fracture of the neck of femur principal character of senile osteoporosis seemingly.
The mechanism of bone forfeiture thinks to relate to the imbalance of bone self process in the osteoporosis.This renewal process is called as the bone remodeling process.This process is carried out in a series of various active bags.These bags seemingly are arranged on sclerotin and the certain bone surface as the bone resorption position spontaneously.Osteoclast (bone dissolving or absorptive cell) is responsible for absorbing the sclerotin of general constant big small portion.After this absorption process is scleroblast (bone forming cell) to occur, fills up the hole that osteoclast stays again by new sclerotin then.
In the grownup of health, osteoclast and osteoblastic formation speed are to make the process of bone forming and bone resorption be in equilibrium state.Yet the imbalance owing to the bone remodeling process in osteoporosis causes the speed of bone forfeiture faster than bone forming speed.All may have to a certain degree unbalance although increase with the age in most of people, at post-menopausal osteoporosis or this unbalance much serious after oophorectomize, and the age of appearance is littler.
The trial that many treatment osteoporosis aspect arranged is to slow down further bone forfeiture or more desirably make sclerotin have a net increase of length.Some medicament as oestrogenic hormon and diphosphate, can slow down the further forfeiture of sclerotin in the osteoporosis.Because bone resorption is different with osteoplastic period, as if can increase sclerotin (about 3-7%) so slow down the medicament of bone forfeiture.But this apparent growth is subjected to the restriction of time, is not progressive, and is that minimizing owing to " reinventing the space " causes.In addition, because be closely related between bone resorption and the formation, stop the treatment of bone resorption finally also can stop bone forming.
Existing people proposes, and treats with Rat parathyroid hormone 1-34 (PTH) can promote the bone turnover and cause positive calcium balance.But the human clinical trial shows that any increase of trabecular bone is offseted by the minimizing of cortical bone (cortical bone), does not therefore have the length that has a net increase of of total sclerotin.
Hefti, et al. is at Clinical Science 62, the middle report of 389-396 (1982) awards normal ash with the bPTH (1-84) of adult female rats subcutaneous dosage every day of suffering from osteoporosis or the calcareous and various bones that hPTH (1-34) can increase whole body and weighs.
Liu, et al. are at J.Bone Miner.Res.6:10, and 1071-1080 points out in (1991), can bring out nearly tibial metaphysis trabecular bone forfeiture 47% after the female rats spay of growing up, and the while is with the obvious increase of scleroblast and girder osteoclast number.Subcutaneous injection every day hPTH (1-34) thus the forfeiture that can reverse trabecular bone fully causes the quantity of trabecular bone to surpass the control group of simulated operation.Osteoblastic number increases and the number decline of osteoclast.
Hock et al. is at J.Bone Min.Res.7:1, and report among the 65-71 (1992) to healthy male rat subcutaneous injection every day hPTH (1-34) 12 days, causes the increase of the calcareous and dry weight of girder and cortical bone.Total sclerotin, trabecular bone volume, little cantilever thickness and number and scleroblast surface have all increased.
The Mammals Rat parathyroid hormone 1-34 as people's (hPTH), (bPTH) and (pTTH) of pig of ox, is the single polypeptide chain with 84 amino-acid residues, and molecular weight is about 9500.Biological activity is relevant in the N-terminal portions, and wherein residue (1-34) obviously is required minimum length.
The difference of the N-terminal fragment of the N-terminal fragment of people PTH and the hormone of ox and pig only has respectively 3 and 2 amino acid residue: hPTH (1-34) Ser Val Ser Glu Ile Gln Leu Met His Asn Leu Gly Lys His Leu1,5 10 15Asn Ser Met Glu Arg Val Glu Trp Leu Arg Lys Lys Leu Gln Asp

The major function of PTH is to cause adaptive variation, to keep Ca in the extracellular fluid
2+Constant density.PTH acts on kidney, increases uriniferous tubules to Ca in the urine
2+Heavily absorption, and stimulate 25-Hydroxy cholecalciferol to be transformed into 1, the 25-dihydroxycholecalciferol.This compound is responsible for Ca
2+Little intestinal absorption.A unusual effect is Ca in promoting bone
2+Move.When PTH acts on bone, increase Ca
2+With phosphatic absorption.PTH stimulates the bone resorption speed of osteoclast, increases the differentiation speed of mesenchymal cell to osteoclast, and the transformation period that prolongs osteoclast.Because the prolongation effect of PTH, osteoplastic osteoblastic number also increases; Therefore, the speed that has improved the bone turnover and reinvented.As if but each osteoblastic activity is lower than normal cell.
Rosenblatt, et al. be at U.S. patent No.4, discloses by disappearance N-end (1-6) amino acid in 423,037,4,968,669 and 5,001,223 and optionally replace Phe7, Met8,18 and Gly12 and the PTH antagonist that obtains.It is reported Tyr34-NH
2Can increase the active and stable of these compounds.
Parathyroid hormone-related peptide (PTHrp), a kind of more than 140 individual amino acid whose protein and fragment thereof can be simulated the main biological function of PTH.PTHrp can be synthetic by tumour and its hetero-organization of many humans and animals, and it can play a role in malignant hypercalcemia.The sequence of hPTHrp (1-34) is as follows: Ala Val Ser Glu His Gln Leu Leu His Asp Lys Gly Lys Ser Ile1 5 10 15Gln Asp Leu Arg Arg Arg Phe Phe Leu His His Leu Ile Ala Glu
20 25 30Ile His Thr Ala?(SEQ?ID?NO:4).
Sequence homology between hPTH and the hPTHrp mainly is confined to 13 N-terminal residues, and wherein 8 is identical; In the receptors bind zone of hPTH (25-34), have only 1 amino acid in hPTHrp, to guard in 10 amino acid.Comformational similarity may be to have common active reason.Cohen, et al. are at J.Biol.Chem.266:3, and 1997-2004 points out in (1991), most of sequence of PTH (1-34) and PTHrp (1-34), and especially zone (5-18) and (21-34) presents alpha-helix conformation.Simultaneously he also points out, whether this conformation is prevalent in that carboxyl terminal also has a question under the physiological condition.This secondary structure is vital for lipid interaction, acceptor interaction and/or structural stability.
We have synthesized the analogue of PTH and PTHrp so that develop therapeutical agent improvement, that be used for comprising the Mammals recovery sclerotin of suffering from osteoporosis.

Cornett, et al. at J.Mol.Biol., has further expanded the research of amphipathic alpha-helix among the 195:659-685 (1987), introduced " amphipathic index " as amphipathic predictor.They reach a conclusion, and it is amphipathic that half all known alpha-helix is arranged approximately, and main frequency is 97.5 ° rather than 100 °, and the residue number of every circle is more near 3.7 rather than 3.6.Although this levels of precision is interesting on science, people's such as Eisenberg basic skills has been used for enough determining whether given sequence is amphipathic, especially starts anew implementation sequence when forming amphipathic alpha-helix as people.
The amphipathic alpha-helix aminoacid sequence that replaces can be not and the given fragment sequence homology of naturally occurring polypeptide, but should have similar secondary structure under physiological status, promptly has the relative polarity and the alpha-helix of non-polar plane.Replace naturally occurring aminoacid sequence with other sequences and may produce favorable influence for physiologically active, stability or other performances of the parent polypeptide that changes.At J.L.Krstenansky, et al., FEBS Letters 242:2,409-413 (1989), and J.P.Segrest, et al.Proteins:Structure, the guidance that designs and select this sequence aspect is arranged among Function and the Genetics 8:103-117 (1990) etc.
10 amino acid whose amphipathic alpha-helixs of the present invention have following formula:
Haa (Laa Laa Haa Haa)
2Laa wherein, Haa is selected from hydrophilic amino acid as mentioned above, and Laa is selected from above-mentioned lipophilic amino-acid.Suppose the ideal alpha-helix, residue 1,4,5,8 and 9 are distributed on the face (A) of spiral, and within about each other 140 °, and residue 2,3,6,7 and 10 occupy 140 ° of another side (B) of spiral.Preferably, all residues that are positioned at one side all are identical polars, and all residues that are positioned at another side all are opposite polarities, if promptly the A face all is hydrophilic, the B face all is lipophilic so, and vice versa.Those of skill in the art know, although spiral of the present invention is to use
Haa (Laa Laa Haa Haa)
2Laa represents, but opposite sequence
Laa (Haa Haa Laa Laa)
2Therefore Haa also meets residue distribution standard, is the describing mode that the another kind of spiral of the present invention is equal to.
L-Ala can replace hydrophilic amino acid or lipophilic amino-acid, because L-Ala can be positioned at any one side of amphipathic alpha-helix without difficulty, although Ala
10Can not form amphipathic alpha-helix.Generally speaking, do not use proline(Pro), halfcystine and tyrosine; Their existence and other random errors can be tolerated in sequence, for example have hydrophilic residue at the lipophilic face, as long as all the other amino acid in the fragment meet the division of hydrophilic-lipophilic face on substantially.Be used for determining that thereby whether a certain sequence has enough amphipathic short-cut methods that can become sequence of the present invention is to calculate its average hydrophobic square as mentioned above.If the average square peak value of each residue surpasses approximately 0.20 in 100 ° ± 20 ° scopes, this sequence can form amphipathic helix and be sequence of the present invention so.
For example, for SEQ ID NO:26, Xaa=Glu, being calculated as follows of 100 ° of average hydrophobic squares of locating each residue: A.A.H
Nδ (N-1) H sinδ (N-1) H cosδ (N-1)E -.62 0 0 -.62L .53 100 .52 -.17L .53 200 -.18 -.50E -.62 300 .34 -.31K -1.1 400 -.70 -.85L .53 500 .34 -.41L .53 600 -.46 -.27E -.62 700 .21 -.58K -1.1 800 -1.08 -.19L .53 900 0 -.53

For this sequence, the peak value of average hydrophobic square appears at 92 °, and its value is 0.48.
When this notion is applied to Rat parathyroid hormone 1-34 and parathyroid hormone-related peptide, can suppose zone (7-16) and (22-31) in a zone or two zones have the alpha-helix secondary structure, and can be with non-homogeneous sequence displacement with similar structures tendency can loss of biological activity or the performance of induction of immunity reaction.Preferred example
