Since all the compounds in the present invention, the substituent in the "C-5-orn" - nitrogen, the substituents on the indicated nitrogen atom may vary, and all connections that have the same R1, R2and R3will refers to Seq ID No. 6.Compounds soluble in the lower alcohols and polar aprotic solvents such as dimethylformamide (DMF), dimethylsulfoxide (DMSO) and pyridine. They are insoluble in the solvents of the type of diethyl ether and acetonitrile.Compounds of the present invention is used as antibiotics, especially as fungicides, or as a means of combating the simplest organisms. As fungicides, they are used to combat both filamentous fungi and yeasts. These compounds are particularly adapted for use in the treatment of fungi is occus, such as C. neoformans and, apparently, Aspergillus: A. fumidatus, A. flavus, A. niger. They are also used for the treatment or prevention of Pneumocystis carinii pneumonia, to which patients with low immune system are especially susceptible, as will be discussed in the future.Compounds of the present invention can be obtained from cyclopeptides formula
< / BR>through a series of transformations, in which the oxygen atom at position C-5-orn" (which can also be named as hemiaminal position) eventually replaced by a nitrogen atom. The starting materials may be natural or modified natural products, as will be subsequently described. If R1-hydrogen, but not hydroxyl, Aza compounds may be obtained from another series of reactions. The method is applicable for producing compounds in which R1can be hydrogen, and hydroxyl described first.The sequence identifiers of the source materials shown in the table. 2.Compound a-4 and a-7 described in the literature (J. Antibiontcs 45, 1855-60 Dec. 1992) as pneumocandin Boand pneumocandin Aoif RI=DMTT.When in the compound A-1 R1and R2presents one of the possible substituents is but the first method. If R3- CH2CN or-CH2CH2NH2the group-CH2CONH2first, it may be converted into a-CH2CN or-CH2CH2NH2as it is consistently described, and all modified compounds (Seq ID Nos. 17-18, 20-21, 23-24, 28-29) can be used in the first method [see I. 2], or otherwise, the compound in which R3-CH2CONH2can be used to obtain compounds with nitrogen in hemiaminal position, and then CH2CONH2group of the obtained product can be converted into a-CH2CN or-CH2CH2NH2.If R1, R2and R3in the source material are the same as in the product, it can be used the following sequence of transformations:
< / BR>*Position C-5-orn" or hemiaminal position.< / BR>At the stage of A starting material, the compound A (Seq ID Nos. 16-30), alkylthiol or arylthiol and acid react in an aprotic solvent in the absence of moisture for a time sufficient for reaction with the formation of compound B (Seq ID Nos. 31-45), shown in the table. 3. It was found that acylaminoacyl well suited for carrying out this stage. Compound B obtained from soedinenii. Examples of strong organic acids are sulforaphane acid, p-toluensulfonate and methansulfonate. Mineral acids include chloroethanol and Hydrobromic acid. It is preferable sulforaphane acid.Suitable solvents are DMF, DMSO, 1-methyl-2-pyrrolidone and hexamethylene phosphoric acid (GMAT). Preferred DMF and DMSO.The reaction in General proceeds at room temperature for 1-10 days.If the reaction cyclopentapeptide connection, thiol and acid are mixed in a suitable solvent before the end of the transformation. The reaction mixture was diluted with water and hold brasindiana flash chromatography, using as eluent 10-40% solution of acetonitrile in water containing 0.1% triperoxonane acid. Triperoxonane acid hereinafter referred to as TFUCK. The fraction containing the target product can be concentrated and lyophilized, and the lyophilized material can be purified preparative high performance liquid chromatography (HPLC).Suitable columns for HPLC are sold under trademarks or trade names of "BOND" (DuP is Tadei B connection C, sulfon (Seq ID Nos. 31-45) is obtained by oxidation of compound B. Suitable oxidizing agents are "OXONE" (KHSO5: KHSO4K2SO4= 2: 1:1, Aldrich Chemicals), m-chloro-peroxybenzoate acid and peroxidasa acid. The sequence identifier (Seq ID) for the connection C is the same as for B, because the atom attached to hemiaminals carbon remains a sulfur atom. Thus, the sequence identifiers (Seq ID) for the sulfones are as follows (see tab. 4).Oxidation of tiefer (compound B) to the sulfone (compound C) is approximately two moles of oxidant. When using one mole of the oxidizing agent the reaction product is a sulfoxide, which may be further converted into a sulfon. In the formation of Aza compounds as intermediates can be used sulfoxidov, but preferable to the use of sulfones. Use a slight excess of oxidant over dumalinao number.The reaction is carried out in the aquatic environment, mainly in a mixture of acetonitrile with water. Preferably about the same grade, although you can use a mixture with ratio from 1:9 to 9:1.When conducting reactivate at room temperature for a time sufficient to complete the reaction of formation of compounds C, typically from 30 min to 1 hUpon completion of the reaction, the compound isolated from reaction mixture by dilution with water and chromatographytandem. For the stage of purification is suitable brasindiana column flash chromatography (C18). The preferred eluent is 30-45% acetonitrile in water (containing 0.1% TFUC) increments of 5%. The desired fractions lyophilizer for targeted intermediate sulfone, compound C (Seq ID Nos. 31-45). The intermediate product is unstable, so the selection should be done as soon as possible.Compound C can be converted into a compound having a nitrogen atom directly attached to the C-5-orn". As shown in the diagram of the synthesis, the reaction of compound C with an alkali metal azide leads to the entry of the azide group at that position, whereas the reaction with ammonia or an amine gives the amino group in position C-5-orn" (compound I). Compound D is an important intermediate product for most of the substances according to the present invention. Although the connection D is a nitrogen atom at position C-5-orn", but because it is not a product, it has a separate nomemade in table. 5.Azide can be obtained by adding an alkali metal azide to a solution of sulfone (compound C; Seq ID Nos. 31-45) in an aprotic solvent with stirring at room temperature for time sufficient to complete the formation of the azide determined by HPLC. After that the reaction mixture can be diluted aqueous acid solution, such as TFUK, and then target azide (compound D) can be isolated from the reaction mixture chromatographically. This is suitable brasindiana column flash chromatography (C18) using 10-25% acetonitrile in water (containing 0.1% TFUC) increments of 5%.Azide (compound D) can be restored to compounds having a free amino group, which is represented among the products of the present invention (Seq ID Nos. 1-15).Recovery may be performed by mixing azide (compound I) with palladium deposited on charcoal (Pd/C), solvent type, glacial acetic acid saturated with hydrogen under a pressure equal to the pressure in the supply tank, in 10-20 hours To separate the product first, the catalyst is filtered off and the filtrate lyophilizer to obtain aminated the ü converted into a substituted amine, as described next.Compound I, in which - NRIIRIIIpresented by group-NHCH2CH2NH2or homologues-NH(CH2)2-4NRIVRVcan be obtained from a sulfone according to the method, according to which the diamine H2(CH2)2-4NRIVRVreacts with sulfona (connection C, Seq ID Nos. 31-45).The reaction is carried out in the previously mentioned aprotic solvent at room temperature. Used an excess of amine is about 10 mol. The reaction is carried out in a period of time from one to several hours.When carrying out the reaction of the appropriate amine is added to a solution of sulfone in an anhydrous aprotic solvent, and the reaction mixture was stirred at room temperature to obtain compound I (Seq ID Nos. 1-15) in which the substituent at position C-5-orn" - NRIIRIII. The target compound can be isolated by diluting the reaction mixture with an aqueous solution of TFUCK with subsequent chromatographic separation. This is suitable brasindiana column flash chromatography (C18) using 10-25% acetonitrile in water (containing 0.1% TFUC) increments of 5%. The appropriate fractions can betwen into the hydrochloride by dissolving in water and passing through a column of Bio-Rad AG2-X8 (Cl-).If in the formula (I) R1is hydrogen, compound I' (Seq ID Nos. 1-3, 15), the nitrogen atom may be directly introduced into hemiaminal position by the formation of the azide, which is then restored in the amine, which in turn may be partially alkylated or allerban to obtain the final product.The reaction shown in the scheme of synthesis.< / BR>Although some natural cyclopentapeptide R1is hydrogen, more often, R1-hydroxyl. Thus, for some compounds, the compound A' scheme of synthesis obtained in the first stage from the corresponding compounds in which R1-hydroxyl.Getting restored connection can be made by mixing appropriate hydroxycodone in solution LiClO4in diethyl ether at room temperature, adding TFUK and subsequent addition of triethylsilane. After that, the mixture is subjected to rapid stirring (4-10 h) up until the original gidroksosoedinenii no longer detected analytical HPLC. After the reaction mixture was poured into distilled water to obtain the recovered product in the form of sediment, cotesia to obtain azide in a purified or unpurified form.The products in which R1is hydrogen, can be obtained by adding the modified cyclopentapeptide to the previously prepared solution N3, N3can be obtained from sodium azide and TFUCK. The reaction proceeds at room temperature to obtain a product containing an azide group, and which may be isolated by conventional methods and purified HPLC.Purified azide can be restored with hydrogen on palladium deposited on charcoal, in aminosidine in a manner similar to the above.Amines obtained, as indicated above, and having a primary amino group-NH2can then be alkylated by conventional means to obtain a substituted amino group. In short, the alkylation can be carried out by the interaction of the corresponding alkylhalogenide with amidon (compound I, NRIIRIII= NH2); Seq ID Nos. 1-15) in an aprotic solvent in the presence of a base to obtain the monosubstituted amine (compound I, NRIIRIIIwhere RII-C1-C4alkyl, C3-C4alkenyl, (CH2)2-4OH, (CH2)2-4NRIVRV). The latter can be separated from the reaction mixture by conventional methods.AMI is icname ways to obtain a substituted amino group. It is assumed that the acyl group-CO(CH2)1-4NH2. Because alleluya acid contains a primary amino group, prior to acylation it is protected by the Deputy type benzyloxycarbonyloxy group. It is preferable to use activated ester type pentafluorophenyl. The acylation can be performed in an aprotic solvent in the presence of a base, such as di(ISO-propyl)ethylamine, at room temperature in a period of time from one to several hours to obtain the product of the acylation. The product can be isolated by diluting the reaction mixture with methanol and purified HPLC (compound I, NRIIRIII=-NHCO(CH2)1-4NH2).Aminosidine, in which the amino group in hemiaminal position is completely replaced, i.e., in which RIIor RIIIare not hydrogen atoms,
< / BR>it is preferable to obtain from sulfone (compound B, Seq ID Nos. 31-45) interaction with the appropriate substituted amine otherIIRIII. The reaction can be carried out by adding the amine to a stirred solution of the sulfone in a period of time sufficient for reaction. The product can be isolated and cleaned the salts of related acids. The connection in the normal way its allocation is obtained as a salt with any acid (related acid). This is usually salt TFUCK. Thus obtained salt can be dissolved in water and filtered through an anion exchange column, the bearing of the target anion. The eluate containing the target salt, can be concentrated to obtain the salt in the form of a solid product.Compounds of the present invention are active against many fungi, in particular against Candida species. Fungicidal properties can be illustrated by the minimal fungicidal concentration (MFC) specific to certain organisms, species of Candida in the experience dilution of the culture of microorganisms is performed in an environment of nitrogen fungal basics with the addition of 1% dextrose (Yeast Nitrogen Base (DIFCO) medium with 1% dextrose (YNBD).In the present experience of connection with an initial concentration of 5 mg/ml were solubilization in 100% DMSO.

SUBSTANCE: the suggested method should be performed at the background of medicinal therapy with preparations out of statins group, tevetene, polyoxidonium and conducting seances of plasmapheresis by removing 800 ml plasma twice weekly with N 5 due to additional intramuscular injection of immunophan 0.005%-1.0 with N 10 and fluimucyl 300 mg intravenously daily with N 5-10, total course of therapy lasts for 2 mo. The method provides modulation of leukocytic functional activity, moreover, due to altered cytokine profile and, thus, through disintegration of protein-lipid complexes participating in the development of atherosclerotic platelets.
EFFECT: higher efficiency of therapy.
FIELD: medicine, phthisiology, anesthesiology.
SUBSTANCE: during the day of operation one should perform autohemotransfusion, then introduce epocrine intravenously by drops at the dosage of 50-200 U/kg patient's body weight; next day after interference one should inject epocrine subcutaneously at the dosage of 25-100 U/kg; at hematocrit level being below 35% 48 h after operation it is necessary to repeat subcutaneous injection of the above-mentioned preparation at the dosage not exceeding 50 U/kg. The present innovation favors hemopoiesis stimulation in postoperational period, that, in its turn, accelerates postoperational rehabilitation in patients of this group and enables, also, to avoid allotransfusions being dangerous because of immunoconflicting reactions.
EFFECT: higher efficiency of compensation.
