Definitions
- the invention is attached to the pharmaceutical field and specifically to compounds with potential application in oncology, with a chemical structure of indolocarbazoles and which are obtained by fermentation of transformed microorganisms.
- Rebecamycin ( Figure 1, A) is a natural product of the bacterium Saccharothrix aerocolonigenes ATCC39243, belonging to the group of actinomycetes (Bush et al. J. Antibiot. 40: 668-678, 1987). Actinomycetes are Gram-positive bacteria whose natural habitat is the soil and which have a great industrial and biotechnological interest, particularly the genus Streptomyces, because they produce a large part of the known bioactive compounds. Many of these compounds have pharmaceutical application due to their antitumor, antibacterial, antifungal, antiparasitic, immunosuppressive, etc. activity.
- Rebecamycin has antibacterial activity against Gram-positive bacteria such as Staphylococcus aureus, Micrococcus lute ⁇ s and Streptococcus faecalis (Bush et al. J. Antibiot. 40: 668-678, 1987). However, his greatest interest is focused on his antitumor activity, which has been demonstrated in vivo against various tumors implanted in mice, and in vitro against several tumor cell lines (Bush et al. J. Antibiot. 40: 668- 678, 1987).). There are currently two rebecamycin derivatives in clinical trials for future use as antineoplastic agents (NB-506, NSC655649).
- rebecamycin belongs to the family of natural products of indolocarbazoles. Since its discovery in 1977, more than 60 natural products of this family have been described, which can be classified into three groups according to containing indole-like structures [2,3-a] pyrrolo [3,4-c] carbazole (p. eg rebecamycin), indole [2,3-a] carbazole (eg tjipanazoles), or £> / s-indolylmaleimide (eg arciriarubin).
- nolopyrrolocarbazoles constitute a new class of antitumor agents, which can be classified into two subgroups according to their mechanism of action.
- a subgroup consists of kinase inhibitors, especially kinase C, and includes staurosporine ( Figure 1, B) and the like.
- the second subgroup consists of agents that damage DNA by acting on topoisomerase I or II, but not on kinases, and includes rebecamycin ( Figure 1, A) and the like.
- indolocarbazoles have, in their chemical structure, two components: indolocarbazole aglycone, and one or more sugars attached to it.
- Indolocarbazole aglycone is biosynthesized from two tryptophan molecules, at least in the case of indolopyrolocarbazoles.
- the sugar is 4-O-methyl- ⁇ -D-glucose.
- sugar is a derivative of L-rhamnose.
- Saccharothrix aerocolonigenes ATCC39243 responsible for the transfer of sugar to indolocarbazole aglycone (Ohuchi et al. J.
- the present invention relates to a process based on the use of rebecamycin biosynthetic genes for the production of indolocarbazoles comprising the following steps:
- Stage 1 Isolation of the Saccharothr ⁇ x aerocoloni ⁇ enes chromosome region that contains, among others, the gene encoding rebecamycin N-glucosyltransferase.
- Example 1 Construction of a library from the genomic DNA of Saccharothr ⁇ x aerocolonigenes ATCC39243. In order to obtain genomic DNA from Saccharothr ⁇ x aerocolonigenes
- ATCC39243 a dense spore suspension of this organism was used to inoculate 250 ml Erlenmeyer flasks containing 25 ml of TSB medium (trypticasein soy broth, Oxoid), and incubated at 28 ° C for 48 hours.
- the cells obtained were collected by centrifugation and then processed following the method of genomic DNA isolation as described in detail in Kieser et al. (Practical Streptomyces genetics. The John Innes Foundation, Norwich, Great Britain, 2000). This genomic DNA was then partially digested with the restriction enzyme Sau3AI, originating DNA fragments of an approximate size of 30 kb.
- Saccharothr ⁇ x aerocolonigenes was used the vector pKC505, which is able to replicate in both Escherichia coli and Streptomyces spp.
- the vector pKC505 was subjected to total digestion with the restriction enzyme Hpa ⁇ , followed by extraction with phenol / chloroform and precipitation with ethanol, and subsequent treatment with alkaline phosphatase (Boehringer Mannheim). After inactivating the phosphatase, the vector was digested completely with the restriction enzyme ⁇ amHI, and subjected to phenol / chloroform extraction and ethanol precipitation. The vector thus treated was then ligated with partially digested genomic DNA (previously obtained) using T4 DNA ligase (New England Biolabs).
- This ligation mixture was packaged, in vitro, in lambda phage particles using a commercially available system ("DNA Packaging Kit", Boehringer Mannheim).
- the phage preparation thus obtained was used to infect Escher ⁇ chia coli ED8767 cells and the transducers were selected on plates with TSA medium (trypticasein soybean broth [Oxoid] with 2% agar) containing 20 ⁇ g / ml tobramycin.
- TSA medium trypticasein soybean broth [Oxoid] with 2% agar
- About 3000 randomly selected transductant colonies were cultured in microtiter plates and, after the addition of glycerol (25% final concentration), this representative library of the genomic DNA of Saccharothrix aerocolonigenes was stored at -70 ° C for preservation.
- Example 2 Analysis of the Saccharothr ⁇ x aerocolonigenes library with an ngt probe.
- This fragment of the ngt gene was obtained by standard PCR techniques, using as a template Saccharothr ⁇ x aerocolonigenes genomic DNA (obtained according to Example 1) and the synthetic oligonucleotides CS003 SEQ ID NO: 20 and CS004 SEQ ID NO: 21, designed from known sequence of the ngt gene (Ohuchi et al. J. Antibiot. 53: 393-403, 2000). The identity of the amplified DNA fragment was verified by cloning into the pUC19 vector and subsequent nucleotide sequencing by standard Molecular Biology techniques. This DNA fragment was used as a probe in a colony hybridization against the Saccharothr ⁇ x aerocolonigenes library.
- Stage 2 Transfer of the ability to biosynthesize rebecamycin to a microorganism of the genus Streptomvces. by introducing said chromosomal region therein.
- the vector pKC505 (as a control) and the four cosmids that included the ngt gene were introduced separately into a strain of the genus Streptomyces by transformation of protoplasts, as described in Kieser et al (Practical Streptomyces genetics. The John Innes Foundation, Norwich, Great Britain, 2000).
- the host strain chosen was Streptomyces albus J1074, which does not produce rebecamycin or any similar metabolite, although any other actinomycete in which the pKC505 vector can replicate can be used for this purpose.
- albus J1074 / 14E8 and S. albus J1074 / 17A12 showed similar chromatograms with each other, with two new peaks (Figure 2, B) not detectable in the extract of the control S. albus J1074 / pKC505 ( Figure 2, A).
- the majority peak showed the same retention time as a pure rebecamycin sample ( Figure 2, C) and showed the characteristic absorption spectrum of rebecamycin.
- the minor peak despite having different retention time, also had an absorption spectrum similar to that of rebecamycin. This minor peak could correspond to a rebecamycin degradation product, as it is sometimes observed in HPLC chromatograms of pure rebecamycin samples.
- the compound corresponding to the majority peak was purified as follows. S. albus J1074 / 14E8 spores were used to inoculate TSB medium (trypticasein soy broth, Oxoid) containing 25 ⁇ g / ml apramycin, and incubated at 30 ° C, 250 rpm, for 24 hours. This preinocle was used to inoculate (2.5%, v / v) eight two-liter Erlenmeyer flasks containing 400 ml of R5A medium. After a 5 day incubation at 30 ° C, 250 rpm, the cultures were centrifuged (12000 rpm, 30 min).
- TSB medium trypticasein soy broth, Oxoid
- the compound of interest was mostly associated with the mycelium, so the supernatant was discarded.
- the mycelium was extracted with 400 ml of acetone, subjected to stirring for 2 hours, centrifuged, and the Organic extract was evaporated in vacuo. This material was redissolved in 5 ml of a mixture of DMSO and acetone (50:50). This extract was subjected to chromatography on a radial compression cartridge " ⁇ Bondapak C18" (PrepPak Cartridge, 25 x 100 mm, Waters), using a socratic elution with acetonitrile and water (55:45) at 10 ml / min.
- the compound of interest was collected from several injections, dried in vacuo and finally lyophilized. This compound was analyzed by MALDI-ToF mass spectrometry using a "Voyager-DE STR Biospectrometry Workstation" spectrometer. As a result, a main peak with a mass of 568 corresponding to that of rebecamycin was obtained, and a secondary peak with a mass of 392 corresponding to the rebecamycin aglycone.
- Stage 3 Obtaining and analyzing the nucleotide sequence of the gene cluster responsible for the biosynthesis of rebecamycin.
- Example 5 Determination and analysis of the nucleotide sequence of the cosmid insert 14E8.
- Cosmid 14E8 was chosen for a more detailed study, and the complete nucleotide sequence of its insert was determined. Sequencing was performed on double stranded template DNA in pUC18, using the method of terminating DNA synthesis by dideoxynucleotides and the commercial system "Cy5 AutoCycle Sequencing Kit” (Amersham Pharmacia Biotech). Both strands of the DNA were sequenced, using an automatic "Alf-express" DNA sequencer (Amersham Pharmacia Biotech). For the computer analysis of the sequence, the GCG program package from the Genetics Computer Group of the University of Wisconsin was used. The sequence obtained (SEQ ID NO: 1) was found to be 25,681 nucleotides.
- ORFs 16 complete and two incomplete open reading frames
- Figure 3 The gene products deduced from said ORFs were compared with proteins of known function present in the databases using the BLAST program. This allowed us to assign probable functions, in a preliminary way, to most ORFs, as shown in Table 1. Table 1.
- Stage 4 Expression of certain genes of said gene cluster in a host organism. to produce indolocarbazoles derived from rebecamycin.
- Example 6 Construction of the recombinant plasmids pREB5, pREB6 and pREB7.
- Plasmid pREB5 was constructed by inserting the DNA fragment between nucleotides 7119 (Sg / ll) and 17783 (EcoRI) of SEQ ID NO: 1 into vector pWHM3 (Kieser et al. Practical Streptomyces genetics. The John Innes Foundation , Norwich, Great Britain, 2000). Plasmid pREB6 was constructed by inserting the DNA fragment between nucleotides 8562 ( ⁇ g / ll) and 17783 (EcoRI) of SEQ ID NO: 1 into vector pEM4 (Quiros et al. Mol. Microbiol. 28: 1177- 1185, 1998).
- Plasmid pREB7 was constructed by inserting the DNA fragment between nucleotides 7119 (BglW) and 22241 (EcoRI) of SEQ ID NO: 1 into the vector pWHM3 (Kieser et al. Practical Streptomyces genetics. The John Innes Foundation, Norwich, Great Britain, 2000).
- plasmid pREB6 contains the promoter of the erythromycin resistance gene (ermE) of Saccharopolyspora erythraea, which would direct the constitutive expression of the included genes.
- ermE erythromycin resistance gene
- Example 7 Production of rebecamycin intermediates in Streptomyces albus due to plasmids pREB5, pREB6 and pREB7.
- the introduction into a given organism of the biosynthetic genes of rebecamycin described in the present invention can be used for various purposes, including: (1) If the organism in question does not naturally produce any type of nolocarbazole, the biosynthetic genes Rebecamycin can be used in:
- rebecamycin derivatives that incorporate new sugars instead of 4-O-methyl- ⁇ -D-glucose.
- the organism in question naturally produces some type of indolocarbazole (such as staurosporine, K-252a, UCN-01, J-104303, AT-2433, arciriaflavins, arciriarububin, arciriacyanine, arciroxocin, arciriaverdine, etc.)
- the biosynthetic genes of rebecamycin can be used for: (a) Improving the production of that indolocarbazole, by using a regulatory gene such as orid8.
- hybrids new indolocarbazoles
- the gene pool of rebecamycin or a part thereof For example, if the orfD11 gene (or the orfD ⁇ and or ⁇ D11 genes) encoding a tryptophan halogenase is introduced, new halogenated indolocarbazoles can be obtained.
- the orfR2 and / or orid7 gene is introduced, new indolocarbazoles with modified sugars can be obtained.
