Description

The invention relates to compounds which are useful for the prophylactic or therapeutic treatment of the effects of endotoxins, including sepsis, septicemia, endotoxemia and various forms of septic shock. More particularly, the invention relates to lipid-A analogs which are useful as inhibitors of endotoxemia. The incidence of Gram-negative bacteremia in the United States is estimated to be approximately 100,000-300,000 cases / year, with a mortality rate of 30-60%. Antibiotics are commonly used as primary chemotherapy for this disease; however, their bactericidal effect can result in bacterial lysis and the concomitant release of endotoxin, a lipopolysaccharide (LPS) residue from the bacterial outer membrane. The released LPS induces a number of pathophysiological events in mammals (collectively referred to as Gram-negative endotoxemia or sepsis syndrome). These include fever, generalized inflammation, disseminated intravascular coagulation (DIC), hypotension, acute renal failure, acute respiratory distress syndrome (ARDS), hepatocellular damage, and heart failure. Although endotoxin induces septic shock, it has little or no direct toxic effect on tissues; on the contrary, it triggers an immunobiological response that leads to a cascade of cytokines, such as tumor necrosis factor (TNF), interleukin-1, interleukin-6, and interleukin-8, and other biological mediators, such as nitric oxide, as well as a series of secondary mediators (such as prostaglandins, leukotrienes, interferons, platelet-activating factor, endorphins, and colony-stimulating factors). The development of pathophysiological concentrations of the above cytokines and inflammatory mediators affects vasomotor tone, microvascular permeability, and leukocyte and platelet aggregation, causing a syndrome called systemic inflammatory response syndrome (SIRS) and septic shock. The bacterial lipopolysaccharide molecule has three main regions: a long-chain polysaccharide (O antigen), a core region, and a lipid-A region. The entire lipopolysaccharide molecule, as well as its individual components, have toxic effects as described above. However, most of the above toxic effects are attributed to the lipid-A portion. Structurally, lipid-A consists of a diphosphorylated disaccharide acylated with long-chain fatty acids. Treatments for endotoxin-related diseases are generally directed at controlling the inflammatory response. Such therapies include corticosteroid therapy, which is used to attenuate endotoxin-mediated cell membrane damage and reduce the production of certain biological mediators; administration of antibodies that neutralize bacterial LPS; treatment with antihypertensive agents or naloxone, which is likely to block the hypotensive effects associated with the sepsis syndrome; and treatment with nonsteroidal anti-inflammatory drugs, which aim to completely inhibit cyclooxygenases and thereby reduce the production of certain secondary mediators, such as prostaglandins and thromboxane. However, none of the above known therapies have resulted in a significant reduction in morbidity and mortality from sepsis and septic shock syndrome. Therefore, there is a long-standing need for agents that can satisfactorily treat the above disease. In USSN 07 / 935,050, filed August 25, 1992 (the contents of which are incorporated herein by reference), Christ et al. disclose disaccharide compounds useful in the treatment of endotoxemia, such as the compound of formula B531. Lipopolysaccharide compounds are also described, for example, by Macher et al. (GB 2179945), Meyers et al. (GB 2220211), Shiba et al. (EP 172581), Anderson et al. (US 4495346) and Shiba et al. (US 5066794). The invention relates to novel lipopolysaccharide analogues for the treatment of sepsis, septic shock, endotoxemia and related disorders. The compounds of the invention have advantageous properties for therapeutic use, such as increased pharmacological selectivity, efficacy and, in particular, increased long-lasting effects. One representative of the compounds of the invention is compound 1 of formula (1-1). The invention further relates to the use of the above compounds for the treatment and prevention of disorders mediated by LPS. Such disorders include, for example, sepsis, septicemia (including endotoxemia), endotoxemia resulting from Gram-negative bacteremia [with associated symptoms such as fever, generalized inflammation, disseminated intravascular coagulation, hypotension, acute respiratory distress syndrome, adult respiratory distress syndrome (ARDS), hepatocellular damage and / or heart failure], and various forms of septic shock (e.g. endotoxic shock). Thus, the compounds of the invention can be used for the prophylactic or therapeutic treatment of localized or systemic inflammatory responses to infections caused by various types of organisms (including Gram-negative bacteria), and for the prevention and treatment of diseases associated with the translocation of Gram-negative bacteria or endotoxin from the intestines. The above disorders are collectively referred to as systemic inflammatory response syndrome or SIRS [for a detailed discussion of the above terms, see Boné et al., Chest 101, 1644-1655 (1992)]. The terms used in this specification are interpreted as follows unless expressly defined otherwise. Alkyl groups are aliphatic, organic groups that have a branched or straight carbon chain and a given In this case, they may be substituted with one or more halogen atoms at any position of the alkyl chain. Alkyl groups are understood to include groups having one free valence, such as the -CH2-CH3 group, and alkylene groups having two free valences, such as the -CH2-CH2- group. It is understood by those skilled in the art that one or two free valences are used interchangeably to describe chemically stable compounds. In the description, prodrugs are understood as compounds which have a lower intrinsic activity than the drug itself, but which, upon administration to a biological system, yield a drug substance either by spontaneous chemical reaction or by enzyme-catalyzed or metabolic reaction. Various prodrugs, such as acyl esters, carbonates, phosphates and methanes, may be mentioned by way of example. The above groups are mentioned by way of example only, without any intention of limitation, of various prodrugs known to those skilled in the art. The above prodrugs of the compounds of general formula (I) are within the scope of the invention. A pharmaceutically acceptable salt is understood to mean a salt of a compound of formula (I) which is formed by reacting the compounds of the invention with an organic or inorganic acid or base. The compounds of formula (I) may be used in both the unionized and salt forms. In practice, the use of the salt form is equivalent to the use of the base form, and both forms are within the scope of the invention. Geometrical isomers are understood to mean trans or cis isomers, which are known to those skilled in the art. All geometric isomers are within the scope of the invention. The compounds of the invention may also contain asymmetric carbon atoms and therefore may exist as stereoisomers, both enantiomers and diastereomers. The invention includes all stereoisomers and mixtures thereof. In the preparation examples described herein, the most preferred isomer is prepared. It goes without saying that asymmetric carbon atoms other than the sugar residue may also be present in the compounds of formula (I), for example in side chains. In this case, all diastereomers thus formed are within the scope of the invention. The figures are briefly described below. Figure 1 shows the inhibition of TNF-α release by Compound 1, illustrating the inhibition of LPS-mediated induction of tumor necrosis factor (TNF) by the compound of the invention in human whole blood. Figure 2 shows the general scheme used to determine the antagonistic potency of an agent in whole blood after incubation for various times. Figure 3 shows the TNF-α inhibitory effect of the test compound of the invention over time, demonstrating that Compound 1 has a longer-lasting effect as an LPS antagonist than Compound B531. These data represent the average of 7 independent experiments, each experiment being performed in triplicate. The invention is described in detail below.

The invention also relates to processes for the preparation of compounds of formula (I). General synthetic processes are described herein which are suitable for the preparation of variously substituted compounds of the invention. The preparation of one of the compounds of the invention, compound 1, is described below. Most of the starting materials and reactants are well known to those skilled in the art. Certain of the starting materials and reactants described in the following preparation process are described in detail by Christ et al. in U.S. Patent No. 5,530,113, filed 07 / 935,050, the contents of which are incorporated herein by reference. One method for preparing the compounds of the invention is described below. Although the preparation of compound 1 is described in this example, other analogs of the invention can be prepared using suitable starting materials. Therefore, this preparation method is actually a general preparation method. For example, by using appropriate alkylating agents in reaction step 22, structurally different analogs can be prepared in terms of the meaning of the R1 substituent. The introduction of the groups indicated for R2 can be ensured in reaction step 15 by using a suitable alkylating agent. In addition, in reaction step 25, by replacing the reactant described herein with a suitable reactant, analogs can be prepared that contain a different group for R3. Analogs without Ra oxygenated side chains can be prepared by minor modifications of the synthetic procedure described below, which are well known to those skilled in the art. For example, to prepare compounds of formula (I) in which RA is methyl, this leaving group in the tosylate product of step 8 can be replaced by an iodine atom in the Finklestein reaction. The iodine compound can be dehalogenated by treatment with zinc metal, HU 221 342 Β1 thus we obtain a compound containing a methyl group in the RA value. An example of the synthesis of the R4 side chain is given below. Various changes in this side chain can be achieved by replacing the original starting material with a suitable starting material, for example, the length or branching of the side chain can be influenced by using the appropriate starting material. Thus, the use of appropriate tosylates in reaction step 6 leads to compounds of general formula (I) containing different R4 groups (reaction scheme 1). The synthesis shown in Scheme 2 provides general routes for the preparation of compounds of the invention (see the working examples for details of the preparation procedure). Although we believe that Process 1 of Scheme 2 is advantageous for the preparation of the compounds of the invention due to various factors, including, for example, the use of cheaper starting materials, higher yields, and less toxic chemicals, Process 2 (Schemes 3-6) described below can also be used to prepare the compounds of the invention. Most of the reactants and starting materials are well known to those skilled in the art. Certain reactants and starting materials for Process 2 of the invention are described in detail by Christ et al. in US 07 / 935,050, the contents of which are incorporated herein by reference. Although the preparation of Compound 1 is described in this example, other analogs of the invention can be prepared using appropriate starting materials. Therefore, the synthesis is a truly general process. For example, using a different alkylating agent to prepare the intermediate of formula U can produce structurally different analogs at the R1 substituent. The group represented by R2 in the preparation of the intermediate of formula O can be controlled by using the appropriate alkylating agent. Additionally, by substituting an appropriate compound for intermediate E in the preparation of intermediate G, analogs with different R3 values ​​can be prepared. The preparation of the R4 side chain is illustrated below (Scheme 3). The preparation of variations of the above side chain can be achieved by replacing the starting material with other suitable starting materials. For example, the length or branching of the above side chain can be controlled by using a suitable starting material. (Details of the synthesis are described in the working examples.) The preparation of the “left-hand” part of the molecule can be carried out according to Scheme 4. The preparation of the "right-hand" part of compound 1 can be carried out by the procedure of Scheme 5. These two parts of the molecule are then coupled using the process of Scheme 6 to produce Compound 1. The invention also relates to pharmaceutical compositions containing the compounds of general formula (I) according to the invention. The lipid A analogs of the invention may be administered at doses that provide adequate inhibition of LPS activation of target cells; these doses are generally preferably in the range of 0.01-50 mg / patient, more preferably 0.05-25 mg / patient, and most preferably 1-12 mg / patient. The above doses are most preferably administered as a continuous infusion over 3 days. Parenteral administration includes subcutaneous, intravenous, intramuscular and intraarterial injections using various infusion techniques. Intraarterial and intravenous injections are administered through a catheter. For certain indications, administration methods that provide rapid delivery to the tissue or organ to be treated are preferred, such as intravenous injections for the treatment of endotoxemia. Pharmaceutical compositions containing the active ingredient may be in a form suitable for any desired route of administration. The aqueous suspensions of the invention contain the active ingredient in admixture with excipients suitable for the preparation of aqueous suspensions. Such excipients include suspending agents such as sodium carboxymethylcellulose, methylcellulose, hydroxypropylmethylcellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and acacia; and dispersing or wetting agents such as naturally occurring phosphatidone (e.g. lecithin), condensation products of alkylene oxides with fatty acids (e.g. poly(oxyethylene) stearate), condensation products of ethylene oxide with long chain aliphatic alcohols (e.g. heptadeca(ethyleneoxy)cetanol), condensation products of ethylene oxide with partial esters of fatty acids and hexyl anhydride (e.g. poly(oxyethylene) sorbitan monooleate). Aqueous suspensions may also contain one or more preservatives, such as ethyl or n-propyl p-hydroxybenzoate. The pharmaceutical compositions of the invention are preferably in the form of sterile injectable preparations, for example sterile injectable aqueous or oleaginous suspensions. These suspensions may be prepared by methods known to those skilled in the art using suitable dispersing or wetting agents and suspending agents, as described above. The sterile injectable preparations may be sterile injectable solutions or suspensions in non-toxic parenterally acceptable diluents or solvents, for example solutions in 1,3-butanediol, or may be lyophilized powders. Acceptable carriers and solvents include water, Ringer's solution, and isotonic sodium chloride solution. In addition, sterile, fixed oils may be employed as a solvent or suspending medium. For this purpose, any sterile, fixed oil may be employed, such as synthetic mono- or diglycerides.Additionally, fatty acids, such as oleic acid, can be used to prepare injectable compositions. Preparations suitable for parenteral administration include aqueous and non-aqueous isotonic sterile injection solutions which may contain antioxidants, bacteriostats and solutes such as: HU 221 342 Bl which render the preparation isotonic with the blood of the patient to be treated; suitable preparations are also aqueous and non-aqueous sterile suspensions, which may contain suspending agents and thickening agents. The preparations may be presented in unit doses or in sealed containers containing multiple doses, such as ampoules or tubes, and may be stored in a freeze-dried (lyophilized) state, to which only the sterile liquid carrier, such as water for injection, need be added immediately before use. Freshly prepared injection solutions and suspensions may be prepared from the sterile powders described above. It will be understood, however, that the specific dosage level useful for treating a particular patient will vary depending on a variety of factors, including the activity of the compound being administered; the age, weight, general health, and sex of the patient being treated; the time and route of administration; the rate of clearance; and other medications previously administered; and the severity of the disease being treated. The compounds of the invention and their preparation and use are illustrated in more detail by the following examples. These examples are presented without any intention of limitation. It is understood that modifications that are obvious to those skilled in the art also fall within the scope of the invention. The compounds of the invention are identified by compound number as shown in Table 1. EN 221 342 B1 Table 1.

Biological examples Both bacterial LPS and bacterial lipid-A induce the production of tumor necrosis factor (TNF), IL-1β, IL-6 and IL-8, as well as other cytokines and cellular mediators in human whole blood and human macrophage cell lines. The production of pathophysiological amounts of the above cytokines plays an important role in the development of systemic inflammatory response syndrome and septic shock. The lipopolysaccharide analogs of the invention inhibit the production of cytokines mediated by LPS and / or lipid-A, as demonstrated by the following experiments. Example A Inhibition of LPS-induced cytokine production in vitro Human whole blood was prepared and assayed according to the method of Rose et al. [Rose et al., Infection and Immunity 63, 833-839 (1995)]. HL60 cells were cultured in RPMI medium supplemented with 10% fetal calf serum and antibiotics, and differentiation into macrophages was induced by treatment with 0.1 pmol / L 1,25-dihydroxycholecalciferol (vitamin D3; Biomol Research Laboratories, Plymouth Meeting, PA) and LPS-mediated IL-8 production was assayed. Briefly, bacterial LPS (e.g., from E. coli 0111:B4; Sigma Chemicals, St. Louis, MO) was added at a concentration of 10 ng / ml, or lipid-A (Daiichi Chemicals, Tokyo, Japan) was added as a 10-fold solution in Ca++- and Mg++-free Hank's balanced salt solution (CMF-HBSS; Gibco). In experiments in which analogs of the invention were tested, the analog was added directly to the LPS or lipid-A in CMF-HBSS. HU 221 342 was added to the reaction mixture before the addition of Β1 (e.g., at a concentration between 0 and 100 pmol / l, as a 10-fold aliquot). The reaction mixture was incubated for 3 hours, then plasma was prepared from whole blood or the culture supernatant was removed and assayed for the presence of induced cytokines using an ELISA assay kit (Genzyme, Cambridge MA) according to the manufacturer's instructions. However, any standard ELISA kit can be used for the above purpose. Experiments were performed at least twice, in triplicate. Lipid-A analogs inhibited LPS-induced TNF production in human whole blood in a concentration-dependent manner. Among the analogs tested, compound 1 was found to be the most potent. The results are shown in Figure 1. The IC50 of compound 1 on LPS-induced TNF production was approximately 1.5 nmol / l. Other analogs, such as compounds 2, 3, 4, 5, 6, 7, 8, 9 and 10, also inhibited LPS-induced TNF production. The IC50 values ​​of these compounds ranged from 1.5 nmol / l to 159 nmol / l. Compound 1 also inhibited LPS-induced IL-8 production in HL-60 (human macrophage-like) cells. Inhibition of IL-8 production in the presence of 1 nmol / L or more of Compound 1 was complete whether LPS or lipidA was used as antagonist. The compounds of the invention similarly inhibited the production of other cytokines induced by LPS in human whole blood even when the above cytokines were produced several hours after LPS administration, for example IL-1β and IL-6 require at least 4 hours to reach maximum concentrations, while IL-8 requires at least 10 hours after LPS administration to reach maximum levels. Using the above methods, the compounds of the invention were administered at concentrations between 0 and 10 pmol / l and LPS at a concentration of 10 ng / ml. The inhibition of the production of TNF, IL-Ιβ, IL-6 and IL-8 was measured as a function of time after LPS administration. The above inhibition of cytokine production was also found to be concentration-dependent, but in all cases the inhibition of cytokine synthesis was greater than 90% in the presence of concentrations of Compound 1 at 10 nmol / l or higher for 24 hours after LPS administration. Example B Persistence of compounds in human whole blood Although some of the compounds of the invention are not rapidly cleared from the circulation, their activity decreases over time, with a half-life of 1-3 hours. This rapid deactivation necessitates continuous dosing to maintain antagonist efficacy. The study of deactivation has led to the development of a method for determining the in vitro deactivation of compounds in human whole blood. The assay is performed by preincubating the lipid A antagonists with blood for various times, then adding LPS as described above, incubating the sample for 3 hours, and then determining the cytokines released. The scheme of the above assay is shown in Figure 2. Using the above assay, we have shown that B531 (described by Christ et al. in US 07 / 935050) is deactivated (i.e., loses its activity with increasing preincubation time). Figure 3 shows that compound 1 is also deactivated, but due to its higher activity and slower deactivation rate, it is still effective after 6 hours, while B531 is only effective immediately after administration. These data are the average of 7 independent experiments, each experiment was performed in triplicate. Example C Inhibition of TNF or IL-6 production in in vitro animal model systems The compounds of the invention inhibit LPS-induced TNF or IL-6 production in whole blood or macrophages isolated from guinea pigs, rats, and mice. Macrophages from Hartley-White guinea pigs (Elm Hill Breeders, Chelmsford, MA) and C57BL / 6 mice (Jackson Labs, Bar Harbor, ME) were isolated from the abdomens of animals that had undergone primary immunization. Primary immunization was performed by intraperitoneally injecting mice with 2 mg of Bacillus calmette guerin (BCG; RIBI Immunochemical Research, Inc., Hamilton, MT) in 10 mg / ml saline, while guinea pigs were injected with 2 mg of BCG in a 7 ml dose volume in mineral oil. Peritoneal macrophages were isolated from the abdomens of the animals 3 days after injection by standard methods.The cells were allowed to adhere to culture plates for 2-3 hours, then cultured in RPMI 1640 medium containing 10% fetal calf serum and LPS was added to a final concentration of 10 ng / ml as described above. To demonstrate the inhibitory effect, the compounds of the invention (concentrations between 0 and 100 pmol / l) were added to the culture medium immediately before the addition of LPS. After a 3-hour incubation period, guinea pig, mouse and rat TNF levels and / or IL-6 levels were determined either by ELISA or, in the case of TNF released from guinea pig macrophages, by cytolytic bioassay [Lymphokines 2, 235 (1981)]. In mouse peritoneal macrophages, compound 1 exerted an excellent inhibitory effect (IC50=16 nmol / l for IL-6 and 20 nmol / l for TNF); The IC50 value for TNF release in guinea pig macrophages was 0.3 nmol / l, while the IC50 value for TNF release in rat peritoneal macrophages was 11 nmol / l. Example D In vitro studies Mice primed with BCG [Vogel S. et al., J. Immunology 124, 2004-2009 (1980)] were used as an in vivo test system to demonstrate the inhibitory effect of lipid-A analogues on 1) LPS-induced TNF production and 2) LPS-induced lethality, as follows. week-old male C57BL / 6 mice (supra) were primed with 2 mg intravenously administered into the tail vein HU 221 342 B1 BCG. Ten days after injection, E. coli LPS (supra) in pyrogen-free 5% glucose solution (Otsuka Pharmaceuticals Inc., Tokyo, Japan) was administered intravenously into the tail vein of BCG-primed mice. LPS was administered at a dose of 1-3 pg / mouse to assay both TNF production and mortality. The test compound was administered as a component of the injected LPS solution at concentrations ranging from 3 to 300 pg / mouse. Plasma was prepared 1 hour after LPS injection and TNF was assayed by the ELISA method described above. Mortality due to septic shock was recorded 36 hours after LPS injection. The compounds of the invention effectively inhibited TNF production after LPS administration. Compounds 10 and 1 effectively inhibited TNF production in vivo in mice (ED50=5 and 10.6 pg / mouse, respectively). Compounds 2, 3, 4, 5, 6, 7, 8 and 9 also inhibited TNF production, with ED50 values ​​ranging from 10 to 200 pg / mouse for compounds 5 and 6, and compound 7 had an ED50 value >100. In parallel experiments in guinea pigs, these analogs also effectively inhibited LPS-induced TNF production in vivo (optimal ED50 values ​​ranged from 2.3 to 6.1 pg / guinea pig for compounds 1, 7, and 10). The lipid A analogs of the invention can be used as active pharmaceutical ingredients to treat or prevent any LPS-mediated inflammation or disorder. Such disorders include, but are not limited to, endotoxemia (or sepsis syndrome) resulting from Gram-negative bacteremia (with accompanying symptoms such as fever, generalized inflammation, disseminated intravascular coagulation, hypotension, acute renal failure, acute respiratory distress syndrome, hepatocellular damage, and / or heart failure); and LPS-mediated exacerbation of latent or active viral infections (e.g., infection with HIV-1, cytomegalovirus, herpes simplex virus, and influenza virus). The lipid-A analog is usually administered dissolved in a pharmaceutically acceptable formulation, for example, physiological saline solution optionally containing 5% glucose. When the lipid-A analog is used to treat viral infections, it may be administered in conjunction with appropriate virucidal agents. The lipid-A analog may be stored as a freeze-dried formulation. Lipid-A analogs are administered in doses that provide adequate inhibition of LPS activation in target cells; generally, this corresponds to a dose of 0.01-50 mg / patient / day, more preferably 0.05-25 mg / patient / day, most preferably 1-12 mg / patient / day. The drug should be administered by injection or infusion as soon as possible after SIRS is diagnosed, based on clinical predictors such as APACHE score [Knaus et al., Chest 100, 1619-1636 (1991) and Knaus et al., JAMA, 1233-1241 (1993)] or other clinical predictors. In addition, the injection or infusion should be administered as soon as possible after exposure to endotoxins or after diagnosis of systemic Gram-negative bacterial infection, especially if an even more rapid and early diagnostic indicator of systemic Gram-negative infection is available. Prophylactic indications for the active ingredients of the invention include their use in the event of a suspected endotoxin infection. This may occur when 1) there is an increased likelihood of systemic (blood) accumulation of endotoxins from systemic or localized Gram-negative bacterial infection (for example, during surgery); 2) increased likelihood that blood concentrations of endotoxin will increase. Under normal physiological conditions, only minimal amounts of endotoxin cross the intestinal endothelium into the visceral circulation. The endotoxin that has crossed is then usually cleared from the body by the liver (and possibly other cells or organs). Blood endotoxin concentrations may increase if the rate of endotoxin clearance by the liver (or other endotoxin-secreting cells or organs) is reduced. Increased intestinal translocation may occur as a result of intestinal ischemia, hypoxia, trauma, or other injury to the integrity of the intestinal lining (or intoxication by drugs or alcohol). Blood endotoxin levels increase when liver function is impaired by disease (cirrhosis), injury (surgery or trauma), or temporary removal (such as during liver transplantation); 3) the body is exposed to endogenous endotoxins that result in an inflammatory response, either acutely or chronically; this may be by inhalation or other means of endotoxin uptake. An example of SIRS-inducing endotoxin uptake is corn dust fever [Schwartz et al., Am. J. Physiol. 267, 609-617 (1994)], which occurs in workers in the grain industry, e.g., in the Midwest of the United States. Such workers may be treated prophylactically, e.g., by daily inhalation of an aerosolized formulation of the invention prior to work, e.g., in the field or at grain elevators. For most other prophylactic and therapeutic applications, intravenous infusion or bolus injection is used. Injection is preferred, but pharmacokinetic requirements may necessitate the use of infusion in some cases. Treatment should be initiated as soon as possible after diagnosis of SIRS and continued for at least 3 days or until the risk of mortality is reduced to an acceptable level.
