(57) Abstract: New ways of obtaining metallizovannyh derivatives [M]-bacteriochlorophyll General formula I, where R1represents a C1-C25hydrocarbon residue; R2represents H, HE or COOR5where R5represents a C1-C12alkyl or C3-C12cycloalkyl; R3represents H, HE or1-C12alkyl or alcokey; each R4is independently selected from the group comprising vinyl, ethyl, acetyl, 1-hydroxyethyl and their ethers and esters; M is a metal with an ionic radius smaller than that of the Cd (r95 PM), and the specified metal selected from the group consisting of a divalent metal selected from the group comprising Pd, Co, Ni, Cu, Zn and Mn, new metilirovannye derivatives [M]-bacteriochlorophyll and pharmaceutical composition containing them. Metilirovannye derivatives bacteriochlorophyll can be used in the methods of photodynamic therapy and photodynamic destruction of viruses and microorganisms. 5 S. and 9 C.p. f-crystals, 1 tab., 2 Il. The invention relates to a new method of obtaining metallizovannyh derivatives bacteriochlorophylls and microorganisms in vitro, and some new metallosalen derived bacteriochlorophyll. Definitions and abbreviationsBChl = bacteriochlorophyll (MD-containing 7,8,17,18-tetrahydropyran formula I, in which further M is an MD, R1is fitilem or geranylgeraniol, R2represents SOON3, R3represents H, R4at position 3 is acetyl and at position 8 - ethyl). BChl derivative = derivative BChl with modifications in the macrocycle, the Central metal atom and/or at the periphery, including derivatives of formulas I, II, III, I', II', III', below. BPhe = bacteriopheophytin-a (BChl in which the Central MD replaced by two atoms of H). Chl = chlorophyll (MD-containing derivative 17,18-dihydroporphyrin consisting of a macrocycle comprising 4 pyrrole rings, and one sollicitudo rings that are conjugated to each other and connected with atom MD). Chlorophyll a has the formula I, below, where R1is fail, R2represents SOON3, R3represents H, R4in position 3 represents vinyl, and at position 8 is ethyl. [M]-BChl = BChl derivative, in which the Central atom MD(Chl, in which the Central MD replaced by two atoms of H). Justification of the invention MD-containing (bacterial plankton)chlorophylls ((C)Chl) and their free base, (bacterial plankton)pheophytin (() Phe) is essential for photosynthesis. They perform the role of an antenna or redox pigments, capable under the action of light to the charge separation in the reaction center. Pigments can also potentially serve as photosensitizers, for example, be used in photodynamic therapy of tumors. It is shown that porphyrins accumulate in the tumor tissue and the irradiation of the tumor tissue absorb light in situ, serving as a means of identifying tumor localization of fluorescence. The crude derived hematoporphyrin known as hematoporphyrin derived or HPD proposed for use for the detection and photodynamic therapy of tumors. Form HPD, which is considered more effective, includes part of the HPD, which have an aggregate weight higher than 10 kDa, and is the subject of U.S. patent 4649151. HPD or its active components are described in U.S. patent 4753958 for local treatment of skin diseases and in the work of Matthews, J. L. et al., 1988, Transfusion, pp. 81-83, for sterilization of biological samples containing infectious organisms, such as tank and proposed several porphyrin derivatives, in which, for example, the Central metal atom forms a complex with four pyrrole rings and/or modified peripheral substituents of pyrrole rings, and/or the macrocycle dehydrogenase to Chl derivatives (chlorine) or tetrahydropyran to BChl derivatives (bacteriochlorin). Complexes of cyclic tetrapyrroles with metals other than MD, investigated in the series of porphyrins and 17,18-dihydroporphyrin to determine their spectroscopic and redox properties (Hynninen, P. H., in: Scheer, 1991, pp. 145-209). Bacteriochlorophylls have potential advantages compared with chlorophyll, because they show intense bands in the area close to the infrared, i.e. at much longer wavelengths, compared with the derivative of chlorophyll. However, currently there is little information regarding the bacteriochlorophylls with a centrally located metal atoms other than MD. PCT international application Publication WO 90/12573 Dougherty describes derivatives of bacteriochlorophyll-a or-b or the corresponding bacteriochlorin, deprived of the Central metal atom, or in which the Central metal atom can be separability metal, selected the " hydrocarbon residue of 8-25S, to obtain compositions used for the destruction or damage of unwanted biological object target, which includes the photosensitivity of the named object an effective amount of the specified derivative, followed by irradiation of the targeted object using radiation of wavelengths corresponding to the absorption band called derived during the period of time sufficient to damage or destruction of the object. In addition, these compounds are applicable for photodynamic therapy and diagnosis. It should be noted that although Sn2+and Zn2+complexes of bacteriochlorophyll-a or-b were stated in the description of the application WO 90/12573, these metal derivatives are not described in the examples and are not described no method of obtaining them. Losev et al. , 1990, Opt. Spektrosk., vol. 69, pp. 97-101 describes the complexes [Pd]-BChl and [Cu]-BChl obtained, as noted, the direct introduction of metal BPhe with Pd benzonitrile in benzene in a stream of nitrogen or by using a concentrated solution of CuCl2in methanol, respectively. However, in this publication, there are no details of the method of obtaining and characterization of metal complexes. Moreover, we were not able to repeat obtaining [Pd]-BChl complex Losev'y. When normal is estnosti connection group BChl labile and have several smaller quantum yields of formation of the triplet state in comparison, for example, hematoporphyrin derivative (HPD). However, their possible role in the launch of biological redox reactions, the appropriate spectral characteristics and light destruction in vivo give bacteriochlorophylls potential advantage over other compounds, such as porphyrins and chlorophylls, in relation to PDT treatment and diagnosis, and to the destruction of cells, viruses and bacteria in the samples and in living tissue. It can be expected that chemical modification of bacteriochlorophylls will lead to further improvement of their properties, but such efforts were extremely limited due to the lack of suitable methods of producing such modified bacteriochlorophylls (Hynninen, 1991). European patent application published for 0584552, the same applicant as the present application, describes the new conjugates of Chl and BChl with amino acids, peptides and proteins for use in PDT therapy and diagnosis. Amino acid, peptide or protein residue is attached directly or via a spacer to the C-173-carboxyl group of the molecule Chl or BChl. These conjugates are obtained by methods, is soft enough to save an acid-labile Central atom MD. There's also opiskelijalle, no method of obtaining them. Patent application DE Germany 4121876 describes derivatives of bacteriochlorophyll, in which the modified esters at positions C-132and C-173obtained in mild conditions rapid alkaline interesterification, allowing subsequent changes in socilism the ring while maintaining the Central Mg, whereby the absorption of the pigment is shifted to below 800 nm. The application also mentions these complexes BChl derivatives with Zn or Ni, but these complexes are not represented in the examples and methods for their preparation is not described. It would be desirable to obtain new complexes BChl for use in PDT with the aim of preserving and even improving favorable optical and physiological properties of the BChls, while respecting their photosensitizing potential, as well as to improve chemical stability and optimizing their physiological periods of life. Replacement metal (transmetallation) leads to noticeable changes in the chemical reactivity and stability of the BChls, which are essential for the new models of the macrocycle and the peripheral substituents, and in particular to optimize their transport, orientation and bi is transmetallation) also leads to marked changes in the properties of the excited state, including output and period of existence of the triplet, the availability of higher levels of excitation and the emergence of cytotoxic derivatives of oxygen. There are several methods of replacing the Central metal atom in the porphyrin (see Buchler, J. W., 1975, "Static coordination chemistry of metalloporphyrins", in Porphyrins and Metalloporphyrins, Smith, K. M., ed., pp. 157-232, Elsevier, New York). Porphyrins are readily available and chemically stable, although their spectral and physiological properties unfavorable. There are several methods of direct and indirect introduction of metal in chlorophyll. Strell, M., Urumow, T., 1977, Liebigs Ann. Chem., pp. 970-974 describe the complexes [Cr]-Chl and [Mn]-Chl obtained by replacing the metal complex [Cd]-Chl (obtained in reactions without metal derived Chl with cadmium acetate in methanol or pyridine) in the reaction with acetate CR++or MP++in methanol in an atmosphere of N2. It is reported that this method of replacement metal suitable for complexes of chlorophyll derivatives with si, Zn, Co and Pb, but not with Fe3+, Ni and SB. However, since the complexes of cu, Zn, Co and Pb can be obtained by direct introduction of metal in Phe, this method is useful only for SG and MP. The authors describe also getting complex [Mg]-Chl a direct introduction of the metal in Phe in acetone using acetate Mnimi the metal atoms, other than MD. The introduction of metal in bacteriochlorophylls, as you know, is more difficult in comparison with chlorophyll due to their reduced reactivity to the introduction of metal and high reactivity of adverse reactions. Described a specific method of introducing MD bacteriopheophytin (Wasielewsky, M. R., 1977, "A mild method for the introduction of Magnesium into bacteriopheophytin-a", Tetrahedron Letters, pp. 1373-76). The applicants of the present invention tried to reproduce the procedures Strell and Urumow, for direct introduction of the metal and its substitution derivatives of chlorophyll, in relation to the obtaining of metal complexes derived bacteriochlorophyll, but all attempts were unsuccessful. Direct introduction of metal derivatives bacteriopheophytin was not possible with any of the used metal, except cu and Zn, and, conversely, led to the discovery in a mixture of unreacted bacteriopheophytin and replaced by metal oxidation products of 3-acetyl-CHL and type. Summary of the invention In accordance with the present invention have now found that the metal complexes derived bacteriochlorophyll can be obtained by modification of the process transmetilirovania (metal replacement) for the introduction of metal in proizvodnoe the invention, thus, relates to a new method of obtaining synthetic substituted metal derivative bacteriochlorophyll formula: [M]-BChl, where BChl represents the balance (demetallizing) without metal, of natural or synthetic derivative bacteriochlorophyll having in position 173group-COOR1where R1represents a C1-C25hydrocarbonyl balance and M represents a metal ion radius less than that of CD (r95 PM), the said metal is selected from the group consisting of a divalent metal selected from the group consisting of Pd, Co, Ni, cu, Zn and mn trivalent metal selected from the group consisting of Fe, Mn and CR, and tetravalent metal selected from the group consisting of Sn and Pt, this process includes: (i) reaction of a suitable derivative bacteriopheophytin having in position 173group-COOR1as defined above, dissolved in dimethylformamide, anhydrous acetate CD in the atmosphere of AG and branches [Cd]-BChl complex from the reaction mixture by chromatography in terms of recovery.

New derivatives of metalloplastikovye of the invention of formulas I', II' and III', as described above, are used as photosensitizers as therapeutic and diagnostic agents, and for the destruction of cells, viruses and bacteria in the samples and living tissues, as is well known in this area for HPD and other photosensitizers. In Fig. 1 shows the toxicity of methyl ether [PD]-hl-173-Serie ([Pd] -BChl-Ser) and methyl ester BChl-173-Serie (BChl-Ser) against bacterial suspensions of S. aureus. In Fig. 2 shows phototoxicity [Pd]-BChl-Ser in relation to the M2R melanoma cells in culture to enable [3H]thymidine. Detailed description of the invention Unlike porphyrins and chlorophylls, direct introduction of the metal in the bacteriochlorophylls difficult. The method of the present invention oswatitsch derivatives [Cd]-BChl, having improved properties in respect of their use as photosensitizers. In accordance with the present invention in the complexes [Cd]-BChl, which are easy to obtain acetate/dimethylformamide method, the metal may be replaced by another metal in mild conditions with excellent output of other metal complexes. Ease of replacement of the metal in the application of [Cd]-BChl as a predecessor amazing and probably partially due to the large ionic radius (rmCd2-(95 PM) compared to MD2+(rm=72 PM). The second factor is the solvent (acetone) in combination with metal counterions (chloride) used in the reaction. When transmetallation formed CdCl2and [M]-BChl in equilibrium with the starting substances, and very low solubility CdCl2in acetone shift the equilibrium towards the formation of products. In one of the embodiments of the present invention R1represents a straight or branched, saturated or unsaturated, including aromatic, hydrocarbon radical, preferably consisting of 1-25 carbon atoms, such as alkyl, alkenyl, phenyl, preferably lower alkyl of C1-C4atoms, most prepost dienyl) or fail (2,6,10,14-tetramethylhexadecane-14-ene-16-yl); and R1' matter or specified for R1or is a hydrocarbon chain substituted by a halogen atom selected from F, Br, C1, I, or HE, oxo, Cho, COOH or NH2or such optionally substituted hydrocarbon chain interrupted by O, S or NH, preferably O, for example, R1' represents the balance of oligoastrocytoma from 4 to 10 carbon atoms, preferably pentoxifyllin. When R1' serves as a spacer for peptide or protein, as is indicated here, it usually contains terminal functional group selected from HE, COOH and NH2through which the terminal functional group of the peptide or protein is attached ether or amide bond. In another embodiment of the invention R1' represents the balance of amino acids or peptide containing a hydroxyl group such as serine, threonine and tyrosine or containing peptides, or a derivative of the specified amino acid or peptide, selected from esters, for example alkyl esters, and N-protected derivatives in which the N-protective group is, for example, tertiary, butoxy, carbobenzoxy or trityl, and the specified gidrauxilirovannaya amino acid or peptide, svodnik are serine methyl ester, methyl ester of N-Fritillaria, methyl ester of tyrosine and methyl ester of N-tributoxy-tyrosine, and an example of such a peptide is the methyl ester of N-carbobenzoxy-serisinin; they all derived, as described in EP 0584552. In the most preferred embodiment of the invention derived [M] -BChl is a [Pd]-BChl, esterified with methyl ester of L-serine. In another embodiment of the invention R1' represents the residue-specific cells ligand selected from peptides and proteins, examples of which are, but not limited to them, hormonal peptides, for example melanocytestimulating hormones (melanotropin), and antibodies, such as immunoglobulins, antibodies specific for tumors. Derivative [M] -BChl of the invention of formula I', where M is Zn or si, can be obtained also by direct introduction of metal devoid of metal (demetilirovanie) BChl derivative, as described below in examples 1 to 4. Some of the metal complexes of bacteriochlorophylls very stable and, thus, can be used for further modifications on the periphery of the tetrapyrrole ring system, which include strict conditions, such as acetic acid riesenie alkyl or aryl esters, can be obtained by the reaction of hydroxyl groups, for example, in position 31 or 132 with the corresponding aliphatic or aromatic acids, chlorides of acids or amino acids, and ethers, in the same positions are obtained by reaction with the appropriate aliphatic or aromatic alcohols. Compounds having a hydroxyl group at position 31, for example derivatives of 3-hydroxyethyl-BChl, or in position 132, for example derivatives 132-OH-BChl, can be obtained by standard methods (see Struck, A. et al., 1992, Bacteriochlorophylls modified at position C-3. Long-range intramolecular interaction with position C-13.2, Biochim. Biophys. Acta, 1101; 321-328 and Hynninen, 1991). In addition, natural failove and geranylgeranylation esters can be preterition in position 173using acid catalysis in other esters, such as ethyl ether, by reaction with the corresponding alcohol. Other substituents can be introduced into the ring of the macrocycle by the reaction of Witha natural WITH groups such as 3-acetyl in BChl a, or introduced chemically such substituents as ketaspire, esterified at C-173and by oxidative addition of Oh groups with the formation of ether bonds in position C-132or by acid-catalyzed esterification HE is active variant modifications on the periphery of the tetrapyrrole ring system are held in a natural derivative of the MD-containing BChl before removing metal (demetilirovaniem). Derivatives BChl of the formula II and III in this case can be obtained from the corresponding natural BChl derivatives of formula 1, as described previously (Struck, A., 1990, "Chemisch modifizierte Bakteriochlorophylle und phaeophytinc in den BindungsstellenA,Bund Ha,bvon photosynthetischen Reaktionszentren aus Rhodobacter sphaeroides R26: Pigmentsynthese, Pigmentaustausch und Spektroskopie", Ph. D. Thesis, University of Munich, Germany). Compounds of the invention in which R1' represents the balance of amino acids, peptide or protein, such as antibody, obtained after replacement metal of the present invention by enzymatic interesterification using enzyme chlorophyllose or by catalytic condensation of the corresponding bacteriochlorophyll (free acid BCh-173-COOH) with gidroksilirovanii amino acid, peptide or protein using dicyclohexylcarbodiimide (DCC) and N-hydroxysuccinimide (NHS) or 4-dimethylaminopyridine (DMAP), as described in EP 0584552, or by acid-catalyzed reactions of unstable MD complexes, such as natural BChl. New derivatives of metalloplastikovye of the invention are intended for use as photosensitizers as therapeutic and diagnostic tools for the destruction of cells, viruses and the tank is enemy, for example, sensitizing neoplastic cells or other abnormal tissue destruction under the action of irradiation, either in vivo or ex vivo using light of the appropriate wavelength. It is believed that the photoactivation energy is transferred to the endogenous oxygen, turning it into a singlet (atomic) oxygen, which is believed responsible for the cytotoxic effect. In addition, photo forms of bacteriochlorophylls fluoresce, and the fluorescence can help in the establishment of localization of tumors or other places in which shall be entered metallosalen bacteriochlorophylls. Examples of known science which can be shown treatment with novel derivatives of metalloplastikovye according to the invention, include the destruction of tumor tissue in solid tumors, the dissolution of plaques in blood vessels (see, for example, U.S. patent 4,512,762); treatment of local disorders, such as acne, athlete's foot, warts, papilloma and psoriasis, the treatment of biological products (such as blood for transfusion) in relation to infectious agents. Derivatives metalloplastikovye of the present invention are formed in the finished pharmaceutical to the region, for example summarized in Remington's Farmaceutical Sciences, Marck Publishing Co; Easton, Penna; latest edition. Compositions can be administered systemically, in particular by injection, or can be applied topically. For the diagnosis of derivatives metalloplastikovye can be used as such or may be labeled with a radioisotope or other means of detection known in science. The number of input derived metalloplastikovye shall be determined in accordance with experience gained in other porphyrins used in PDT, for example, it should vary depending on the choice of a derivative that is used as the active ingredient, violations subject to treatment, method of administration, the age and condition of the patient and doctor. The wavelength of the irradiating light is mainly selected in accordance with the maximum absorption metallobiomolecules photosensitizer. A suitable wavelength for any of the compounds can be easily identified by its absorption spectrum. In addition to the use of in vivo derived metalloplastikovye of the invention can be applied to materials processing in vitro for the destruction of the subject subsequent transfusion, can be treated with compound of the invention and irradiated to achieve sterilization. Thus, the invention also relates to pharmaceutical compositions comprising the derivatives of metalloplastikovye these formulas I', II' and III' for photodynamic therapy and diagnosis of malignant tumors and for photodynamic destruction of cells, bacteria and viruses. For these purposes, the composition should be obtained and entered by traditional methods, for example as described in U.S. patent 4649151, 4753958, 5256840 and 5238940, the Application for the European Patent 0584552 and PCT Application WO 90/12573, each of which is incorporated herein by reference.
