it relates to derivatives; G-CSF (factor<sub>: </sub>They are characterized by good stability of the processes for their preparation. The following are inventive stimulant granulocytes of the solution, and further include a description. the composition of pharmaceutical preparations containing these derivatives.
BACKGROUND OF THE INVENTION
A group of stimulating factors are proteinaceous hormones that stimulate proliferation. and the function of specific types of blood cells such as grariulocytes. Granulocytes absorb and destroy harmful microorganisms and cell debris, and thus represent a vital factor in response to infection. In this regard, granulocytes may form certain, pseudo-clumps and may be released from the vascular system of endothelial cells. Neutrophil granulocytes can then come into direct contact with and destroy microorganisms using specific enzyme systems, such as those they generate. superoxide anions. Because. granulocytes. having only a short circulating life (approximately 6-12 hours) and being destroyed in the course of their function, it is essential for bone marrow stem cells to generate as many granulocytes as red blood cells every day. The rate of granulocyte production further increases enormously if infection occurs. Conversely, if bone marrow is damaged, granulocyte counts decline rapidly, eg as a result of chemotherapy in the case of cancer, radiation, AIDS, or haematological disorders; the result of this rapid change is the susceptibility of patients to insurmountable infection. True sepsis is a general cause of death in cancer patients whose marrow is damaged by radiation, chemotherapy or a disorder, neoplasticity.
The existence of G-CSF has been described in Wallet K. et al.

A / Publication No. WO 87/01132. G-CSF has been shown to stimulate granulocyte production in vivo, with minimal side effects. It appears that human G-CSF can find post-therapeutic use in the management of neutropaenia associated with chemotherapy, radiation therapy, radiation diseases, or bone marrow transplantation. In addition, it can be used to stimulate bone marrow suppression associated with AIDS, to treat myelodisplastic syndromes, characterized by abnormalities in granulocyte function, and to assist in the treatment of serious infections.
In addition, certain of the foregoing G-CSF analogs have been described in PCT Patent Publication No. WO 87/01132, European Patent Publication No. 243,153, European Patent Publication No. 256,843, European Patent Publication No. 272,703 and the journal Biochemical and Biophysical Research Communicatidh (1989), vol. 159, no. 1, pp. 103-111, and tor al. Modification of G-CSF
Kuga t
[Ser] G-CSF was affected by the substitution of cysteine and serine residues at position 17, but these. the changes had no anticipated effect (Protein. Engineering, Vol. 3, No.4, p. 360 (1990))
G-CSF and its analogs are unstable in solution, tend to precipitate out of solution on standing, resulting in their short-term stability and storage problems at high concentrations. In addition, G-CSF and certain analogs tend to covalent aggregation upon storage.

It has been found to be advantageous to use a pAT153-derived vector comprising:
i) a promoter and an operator thereto, e.g. the trp promoter or T7A3 promoter. T7A3 is the A3 promoter of bacteriophage T7
(See Dun JJ and Studier FW: J. Mol. Biol. 166, 477-535 (1983). Full nucleotide DNA sequence).

a ribosome binding site sequence, e.g., a binding site of the ribosome binding site iii) a cloning site for the gene to be expressed; iv) a T4 transcriptional terminal sequence (see SEQ ID NO: 51 and FIG. 4).
v) cer sequence (Summers D. et al. MGG, 201, pp. 334-338;
1985} (vi) the tetracycline repressor gene (tetracycline repression gene) Tet R vii) the gene responsible for resistance to tetracycline Tet A »
viii) multiple restriction enzyme recognition sequences
SEQ ID No. 50 provides a sequence that includes an EcoRI restriction endonuclease cleavage site (nucleotides 1-6), an A3 promoter sequence (nucleotides 7-52), a leader sequence for a trp ribosome binding site (nucleotides 53-78), and a translational initiation sequence. codon (nucleotides 79-81).
It may be advantageous to cultivate host cells capable of expressing a given derivative in a growth medium with enrichment of the culture medium. an additive containing yeast extract; It is preferred that the addition of the yeast extract substances occurs after the start of the cultivation, but before the start of production monitoring. The dosing must be adjusted to prevent it from occurring during cultivation.
yeast extract in medium. Furthermore, it is particularly advantageous; Use of a production vector with the T7A3 promoter.
At the same time advantageous. culturing a host transformed with a recombinant vector carrying the genetic material for a given derivative may be in the presence of leucine and / or threonine in an amount sufficient to improve the accumulation of the derivative. It is particularly advantageous to influence the fermentation by the presence of leucine, who used the production promoter containing the promoter.
In addition to the discovery of modifications to G-CSF or a derivative thereof that includes some or all of the amino acid sequence and at least one of the properties of naturally occurring G-CSF. The present invention is further based on the discovery of modified techniques for the purification of such G-CS factors and derivatives thereof.
For example, it does not exist. no disclosure in PCT Patent Publication No. WO 87/01132, describing a method for removing a detergent, especially N-lauroylsarcosine, occurring in the form of a salt (Sarkosyl), from the G? CSF analogs prepared in this publication. Accordingly, it was necessary to determine such a way that the stability of the G-CSF derivatives of the invention in solution could be determined at high concentrations and that the desired formulation studies (designs) could be performed.
E.g. it is stated in the invention that the removal of detergent can be influenced by phosphate buffer (pH 7.2-7.5). The phosphate buffer may be prepared from isotonic salts and may have the composition described in Example 1. Less useful are other in this regard. buffers, - Whereas; This means that there is less detergent removal, in particular

—Dia f ± 11 raci ™ s<sup>and_</sup>For example, it is preferable to dialysis by routine di f ΰζηϊ '*. It has further been discovered that the concentration of detergent, especially N-lauroylsarcosine in the form of a salt, can be reduced to below 1¾ the concentration if it decomposes during chromatography. Since the possibility of removing the detergent can be increased by reducing its initial concentration, the detergent is already used at the minimum initial concentration, e.g. the same for N-lauroylsarcosine; concentration which decomposes during chromatography.
Particular detergent concentrations are from about 0.8% to about 0.2%, preferably from about 0.5% to about 0.2%, preferably at about 0.3%.
In addition to the above, it has been found that the removal of a detergent such as N-lauroylsarcosine. in the form of a salt such as sarcosyl, activates traces of proteolytic activity that can. complicate product formation · There was; It has been found that this proteolytic activity can be significantly reduced or eliminated if, after removal of the detergent by diafiltration, the pH is lowered below pH 7.0 by diafiltration or better by dialysis. Another part of the invention states that the reduction or elimination of proteolytic activity can be achieved at a pH that is less than pH 7.0, but is high enough to exclude some possible hydrolysis of the polypeptide. A suitable pH is in the range of 6.0 to 4 & gt; 5, preferably a pH. from 5.8 to 5.0, in particular pH 5.4. It is also an advantage that contaminants produced by E.coli and / or due to the presence of degraded or improperly synthesized protein may be under the action of a lower · · <··· -<sup>Α</sup>· -<sup>;</sup>7í. ' The pH was excreted by precipitation. It is preferred that for purification, chromium-based chromium-based size separation (gel chromatography) is used, since otherwise the risk of proteolytic degradation increases, while the previous action (lowering the pH) reduces the possibility of such degradation without using chromatography is difficult to rule out.
Furthermore, the stability of G-CSF and its derivatives is mentioned. v. _r.oz.toku allows, simplify..process.-xtraction ...
In the present invention, a method for extracting -—<sup>:</sup>—Active — if — previously — defined — derivatives — consisting of:
1) suspending said inclusion particles in a detergent, in particular N-lauroylsarcosine, in the form of a salt.
2) oxidation
3) removing the detergent as previously described
4) maintaining the solution obtained by subsequent removal of the detergent at an elevated temperature of, for example, 30-45 ° C, more preferably 34-42 ° C, thereby precipitating contaminating bacterial proteins, oligomeric products, or degradation products. Said solution is maintained at this temperature for 6-24 hours, preferably 8-18, or 10-14, especially 12 hours.
For example, the extraction process may start with glabrous host cells followed by centrifugation to obtain inclusion particles, e.g., in the form of pellets. The inclusion particle may then be suspended in a detergent such as N-lauroylsarcosine in the form of a salt (Sarkosyl), at a concentration of 1-3%, especially about 2% of the N-lauroylsarcosine in the form of a salt. This is followed by oxidation of the suspension in the detergent, e.g. in the presence of copper sulfate, which may be followed by further centrifugation.
If possible, the inclusion particle may be included

Extraction allows simplification of the whole product. In addition, the high yield of the product after the process (referred to in point 4) (effect of elevated temperature) is one of the consequences of the increased stability of the derivatives in the process. solution. Of course, the greater the stability of the derivative in solution, the better the protein is ready for re-extraction. It is preferable to use extraction for derivatives in which the stability in solution is at least 85¾ at a concentration of 10mg / ml. E.g. when the known -117 [Met, Ser] G-CSF analog was extracted according to the above procedure, it appeared after rpHPLC that only 40 µl of the desired product remained in solution after heat treatment of the eluate containing only 1mg / ml protein. At a protein concentration of 3mg / ml, only 19¾ of the analog remained in solution.
All nucleotide sequences in the invention are by convention indicated from the 5'-3 'end.
All derivatives are derived from human G-CSF, which can be expressed as hu G-CSF.
Generally, in all of the examples described, Met preference was present since all derivatives were prepared using E.coli cells.
The following materials are referred to in the Examples and Examples, - their description is as follows.
The term N-lauroylsarcosine always refers to this salt, which is present in the form of a salt. In the Examples it is. this is the sodium salt of N-lauroylsarcosine.

Stability of solutions of G-CSF and its derivatives
Appropriate dilutions of the G-CSF stock solution and derivatives in alkaline phosphate buffer (PBS) at 4 ° C described in Example 9 were tested for solution stability. Solutions containing 1mg protein / ml, 5mg protein / ml and sometimes 10mg protein / ral PBS were incubated at 37 ° C for 14 days. The solutions were visually inspected at regular time / intervals for clot formation. After 14 days, each solution was centrifuged at 14,000 rpm for 20 minutes, the supernatant was removed by decantation and the precipitate was redissolved in PBS containing 1% w / v N-lauroyl-sarcosine. The total protein content of each supernatant and redissolved precipitate was determined by measuring the absorbance of the solutions at 280 nm. and the monomer content of each sample was determined by reverse phase chromatography on HPLC. The results were expressed as a percentage of the corresponding data obtained for the solutions at the start of incubation and the 1 mg / ml pro-solution incubated at 4 ° C for 14 days. Differences between total protein and assayed monomer were observed only in some re-dissolved precipitates. The percentages of residual proteins in the superhatant, for each initial concentration, are shown in the Table.

This repression system stops expression of the tetA gene in the absence of tetracycline, unlike most drug resistance mechanisms that have constitutive expression. . ..
The tet locus was first mapped to RP4 by Barth and Grinter (J. Mol.Biol. 113, 455-474, 1977). It was found to consist of adjacent genes: tetA, structural resistance gene and tetR, repressor gene and this region was

RP4 has a single site for BglII, has five sites for cleavage of SmaI (Lanka, Lurz and Furste, Plas: 10, 303-307, 1983).

i) Cloning of the tetA + tetR gene
Plasmid RP4 is well described (Datta et al., J. Bacteriol., 108, 1244, 1971) and is freely available. Further, plasmid RP4 is stored in the National Collection of Type

E. coli strains containing<sup>-</sup>puppies<sup>2 </sup>they were grown on selective culture media and plasmid DNA was isolated on a larger scale according to the method of Holmes and Quigley (Holmes and Quigley, Anal. Biochem. 114, 193-197, 1981). It was deproteinized with 2.5 M ammonium acetate and reprecipitated with isopropanol. This plasmid; ·· .., · '· -. ·' '.' . *.
The DNA was treated with BglII restriction endonuclease following the manufacturer's recommendations. Further, it was partially cleaved to Xmal using a diluted enzyme and a short incubation time. XmaI is the SmaI isoschizomer that produces 4-nucleotide cohesive termini at the cleavage site.

The vector plasmid pUC8 (Yanisch-Perron, Vieira and Messing, Gene, 33, 103-119, 1985) was prepared in a similar manner, the final form was obtained by digestion with BamHI and XmaI. RP4 fragments were cloned into this vector by ligation with T4 ligase at. 12 ° C for 16 hours. The recombinant vector was used to transform competent calcium chloride-treated E. coli C600 cells (Maniatis et al., Cold Spring with .alpha. @. @ .Alpha. @ .Alpha.). . '»Í <V -Λ · Υ · 7 y λ

3004. The genotype of E.coli C600 is K12 thr-1 leuB6 thi-1h, 11 lacYl tonA21 A<sup>_</sup>cyne44. Several colonies with this resistance have been tested for the putative phenotype (ampicillin and tetracycline resistance, but not kanamycin resistance, which is inherent to RP4 alone). Colonies with correct resistance were subjected to; isolated plasmid DNA 'cloning analysis (Holmes and Quigley). These preparations were digested with EcoRI and HindIII and analyzed by goal electrophoresis. The size of the cloned inserts was determined to be 2.45 kb, indicating a BglII-Xmal-Xmal fragment from RP4. The clone carrying this fragment containing the tetA and tetR genes was designated pTB344.
ii) Removal of the tet gene from pAT153
It was necessary to remove the tet gene from the vector plasmid pAT153, before inserting the tetA + tetR gene set from RP4 into the predominant gene duplication that could be a source of genetic instability. Thus, the tet gene cannot be effectively suppressed by not related etR. Removal was performed by isolating the pAT153 plasmid DNA and digesting it with EcoRI and Aval. A synthetic oligonucleotide of SEQ ID NO: 59 was cloned between these sites:

These cohesive ends are complementary to the EcoRI and Aval cohesive ends and further comprise SphI, BamHI and ClaI sites.
After transformation and selection, colonies were tested for loss of tetracycline resistance-determining factor. Plasmid · _.
DNA from one clone was sequenced to confirm that it contained the predicted correct sequence. This plasmid was designated pCH19.
iii) Introduction of tetA + tetR genes
The TetA and TetR genes were isolated from pTB344 on the EcoRI-PstI fragment. The pUC8 vector was digested with SspI because it carries the same selection factor (ampicillin resistance) as pCH19. Plasmid DNA of pH19 was digested with EcoRI and PstI and then ligated with the 2 & gt; 45 kb fragment carrying the tet genes. The resulting recombinant plasmid was then used to transform E.coli C600 cells, and the culture of the transformed cells was then selected for tetracycline resistance. The insertion of tet genes was determined to replace most of the bia genes in pCH19, which could cause the loss of its ampicillin resistance factor. This loss of ampicillin resistance from transformed cells was confirmed. Several clones were then used to isolate plasmid DNA that was subjected to restriction analysis. This confirmed that<sup>_</sup>the constructed plasmid had the desired structure. The plasmid was designated pTB351.

iv) Insertion of the cer sequence
The naturally occurring 'plasmid ColEI' is stable in E. coli / while its derivatives pBR322 and pAl3:
they are not stable in E. coli. Summers and Sherratt (Cell,,
1097-1103, 1934) found that this is due to ί
the derivatives do not contain a short (283 bp) sequence called cer,;
which is present in the parent plasmid. This sequence contains a specific site responsible for the decomposition of plasmid multimers, which prevents the accumulation of these multimers resulting from homologous recombination. These multimers have;
a deleterious effect on the division process that normally ensures stable properties of daughter plasmids during bacterial division.
Cer sequence (Summers, D. et al., MGG, 201, 334-338,
(1985) was isolated from plasmid pKS492 (enabled by D. Sherratt) as a 289 bp fragment by digestion with BamHI and Taql.
Plasmid pTB351 was. isolated as DNA from dams of the E.coli strain to prevent blocking of its Cla1 site by the dam + methylation system. This DNA was digested with BamHI and ClaI (both;
It was introduced into a synthetic oligonucleotide for this cloning). The cer fragment was ligated with the digested vector and then used to transform E.coli C600 cells. Selection was performed for tetracycline resistance. Transformed?
the cells were subjected to cloning analysis by Aval restriction endonuclease and gel electrophoresis. The presence of an additional 1 zon DNA indicates increment of the cer fragment. Further restriction analyzes were performed to confirm the correct structure of the resulting plasmids. One of these plasmids was designated J pTB357 (Figure 5) and was also designated pLBOO4. J

(B) Plasmid pCH101
Plasmid pCH101 corresponds to plasmid pICI 0020 (see Example 1d 1c), except that the EcoRI-SalI fragment (see Figure 1) is replaced by a fragment consisting of SEQ ID NO: 53 (see also Figure 6) and the gene the sequence of interferon α as described by Edg MD et al., Nucleic Acids Research 1983, Vol.
11, 6419-6435. In this regard, the 3'-terminal codon of ATG of SEQ ID NO: 53 is immediately followed by a TGT codon that encodes a cysteine (amino acid 1) in the interferon sequence as described in the previously mentioned reference Edge, MD et al .: Nucleic Acids
The sequence of GAT-CCA-TG --- and the 'complementary 3' GTAC nucleotide sequences are then deleted from the nucleotide sequence. according to the previously mentioned reference.

c) Insertion of the expression gene set into pTB357
An expression set of genes consisting of the trp promoter, the ribosome binding site, and the. interferon was isolated from plasmid pCH101 (see previous point b) 'on the restriction fragment EcoRI-SphI. It was then ligated into a production vector (pTB357) (see previous point a) also digested with EcoRI and SphI.

d) Insertion of the T4 transcription terminator into pTB244
The T4 transcription terminator sequence, in the form of a SalI to HindIII (67 bp) fragment (see SEQ ID No. 51 and Figure 4a), was inserted into the multiclonal site of the intermediate vector pTB244 between SalI and HindIII sites. A cloning analysis was used to confirm the composition of this constructed gene (pTB244.T4 ter.). The SstI-SphI fragment containing the majority of the multicloning site and the T4 terminator Ty were isolated from this vector. then they were. embedded in pLBOOS ,. cleaved, also SstI and SphI, replacing the interferon α1 gene, but leaving a set of genes comprising the trp promoter. This constructed gene was subjected to cloning analysis and the plasmid was designated pLB013.
e) Substitution of the multicloning site
The presence of a multiclonal site is not ideal in plasmid pBL013 for several reasons: SalI, BamHI and SmaI sites are not the only plasmid, but occur. there were a few: This fragment was therefore cleaved with Ssl and XbaI (both sites are in a single copy on the vector) and replaced with ν '»' - 'ί
