Description

The present invention relates to the use of a compound of formula (Ia) or (Ib) for the treatment of latent tuberculosis.

BACKGROUND OF THE INVENTION Mycobacterium tuberculosis is 2 per year.
More than 1 million deaths and the leading cause of death among people infected with HIV ¹
(Non-Patent Document 1). Regardless of decades of TB (TB) control program, about 2 billion people are asymptomatically infected with Mycobacterium tuberculosis. About 10% of these humans are at risk of developing active TB during their lifetime ² (Non-Patent Document 2). The global pandemic of TB is fueled by HIV infection of TB patients and an increase in multi-drug resistant TB strains (MDR-TB). Reactivation of latent TB is a high risk factor for disease onset and causes 32% of deaths in HIV-infected patients ¹ (Non-patent Document 1). In order to control the TB epidemic, what is needed is to find new drugs that can kill dormancy or latent gonococci. Dormant TB can be reactivated by several factors such as suppression of host immunity through the use of immunosuppressive agents such as antibodies to tumor necrosis factor α or interferon-γ and can cause disease. In the case of HIV positive patients, the only prophylactic treatment available for latent TB is rifampicin, a pyrazine amide 2 to 3 month regimen ( ^3,4 ). Reference 4). The effectiveness of treatment regimen is not yet clear, and the length of treatment is an important constraint in a more limited environment. Thus, there is a strong need to identify new drugs that can serve as chemopreventive drugs for patients with latent TB bacilli. Tuberculosis enters into healthy humans by inhalation; they are phagocytosed by lung alveolar macrophages. This leads to a potent immune response and the formation of granuloma consisting of macrophages infected with M. tuberculosis surrounded by T cells. After 6-8 weeks, the host immune response causes deposition in peripheral cheese-like material having a certain extracellular bacilli surrounded by a layer of dead and macrophages, epitheloid cells and lymphoid tissues of infected cells by necrosis ⁵ (Non-patent document 5). In healthy humans, most of the mycobacteria are killed in these environments, but a small percentage of gonococci still survive and appear to be non-replicating, hypometabolic, and isoniazid (is
which are resistant to killing by anti -TB drugs like Oniazid) ⁶ (Non-Patent Document 6). These bacilli can remain in a modified physiological environment even during the lifetime of a human being without showing the clinical symptoms of the disease. However, at 10%, these latent gonococci can reactivate and cause disease. One hypothesis for the emergence of these surviving bacteria is the pathophysiological environment in human lesions: reduced oxygen tension, nutrient limitation and acidic pH
⁷ (Non-Patent Document 7). These factors have been regarded as making these bacteria phenotypically resistant to major anti-mycobacterial drugs ⁷ (Non-Patent Document 7).

U.S. Patent No. 6,057,031 describes substituted quinoline derivatives useful for the treatment of mycobacterial diseases. The document discloses the antimycobacterial properties of substituted quinoline derivatives against sensitive susceptible mycobacteria strains, but does not describe their activity against latent, dormant, surviving mycobacteria.

) And their N-oxides, addition salts or physiologically functional derivatives (ph
Defines all possible stereoisomers that syologically functional derivatives) may have. Unless otherwise stated or indicated, the chemical name of a compound refers to a mixture of all possible stereochemical isomers containing all diastereomers and enantiomers of the underlying molecular structure. In particular, the stereogenic center is R-
Alternatively, it can have an S-configuration; substituents on a divalent cyclic (partially) saturated group can have either a cis- or trans-configuration. A compound containing a double bond may have E (entgengen) or Z (zusammen) -stereochemistry at the double bond. The terms cis, trans, R, S, E and Z are well known to those skilled in the art. The stereochemical isomers of the compounds of formula (Ia) and (Ib) are clearly intended to be included within the scope of the present invention.

According to the CAS nomenclature agreement, if there are two known absolute configuration stereogenic centers in a molecule, the lowest numbered chiral center, the R or S descriptor in the reference center (descriptor) ) Is specified (based on Cahn-Ingold-Prelog ranking rule). The configuration of the second stereogenic center is indicated using the relative descriptive characters [R *, R *] or [R *, S *], where R * is always defined as the reference center and [R * ,
[R *] indicates a center having the same chirality, and [R *, S *] indicates a center of the same chirality. For example, when the lowest numbered chiral center in the molecule has the S configuration and the second center is R, the stereographic character is defined as S- [R *, S *]. When “α” and “β” are used: the position of the highest priority substituent on the asymmetric carbon atom in the ring system with the lowest ring number is always “α” in the mean plane, which is always determined by the ring system. It is in the position. The position of the highest priority substituent on another asymmetric carbon atom in the ring system relative to the position of the highest priority substituent on the reference atom is when it is on the same side of the average plane determined by the ring system Is called “α” or “β” if it is on the other side of the mean plane determined by the ring system.

Where a particular stereoisomer is indicated, this is that the form is substantially free of other isomers, ie less than 50%, preferably less than 20%, more preferably less than 10%, even more preferably 5% Less than, more preferably less than 2% and most preferably less than 1%. Thus, when a compound of formula (I) is defined as, for example, (αS, βR), this means that the compound is substantially free of (αR, βS) isomers.

Compounds of formula (Ia) and (Ib) can be synthesized in the form of a racemic mixture of enantiomers, which can be separated from each other according to resolution methods known in the art. Racemic compounds of formula (Ia) and (Ib) can be converted into the corresponding diastereomeric salt forms by reaction with a suitable chiral acid. The diastereomeric salt forms are subsequently separated, for example, by selective or fractional crystallization and the enantiomers are liberated therefrom by alkali. Another method of separating the enantiomeric forms of the compounds of formulas (Ia) and (Ib) involves liquid chromatography using a chiral stationary phase. The pure stereochemical isomer is
It can also be derived from the corresponding pure stereochemical isomers of suitable starting materials, provided that the reaction occurs stereospecifically. Preferably, if a particular stereoisomer is desired, the compound will be synthesized by a stereospecific manufacturing method. These methods will advantageously use enantiomerically pure starting materials.

Tautomers of compounds of formulas (Ia) and (Ib) comprise, for example, compounds of formula (Ia) and (Ib) in which the enol group is converted to a keto group (keto-enol tautomerism) And

N-oxide forms of the compounds according to formula (Ia) and (Ib) are one or several thirds.
It is intended to comprise compounds of formula (Ia) and (Ib) in which the secondary nitrogen atom is oxidized to the so-called N-oxide.

Compounds of formula (Ia) and (Ib) can be converted to the corresponding N-oxide form according to methods known in the art for converting trivalent nitrogen to its N-oxide form. The N-oxidation reaction can generally be carried out by reacting the starting materials of formula (Ia) and (Ib) with a suitable organic or inorganic peroxide. Suitable inorganic peroxides comprise for example hydrogen peroxide, alkali metal or alkaline earth metal peroxides such as sodium peroxide, potassium peroxide; suitable organic peroxides are peroxy acids such as benzene carboperoxo Acid or halo-substituted benzene carboperoxo acids such as 3-chlorobenzene carboperoxo acid, peroxoalkanoic acids such as peroxoacetic acid, alkyl hydroperoxides such as t.

Results and Discussion An in vitro dormancy model of dormancy has been developed based on Wayne's oxygen-depleted method of forming dormant bacteria ^9,10 . In Wayne's model, mycobacteria settle to the bottom of the flask, so they form an oxygen gradient, creating an anaerobic condition at the bottom of the flask. This transition to hypoxia renders mycobacteria dormant, which upregulates several genes including isocitrate lyase and glycine dehydrogenase (upreg)
led to expression). These enzymes are responsible for the production of energy in the absence of oxygen and the terminal electron acceptors are nitrates, sulfates, etc. compared to molecular oxygen in the case of aerobic respiration. The energy of the reduced substrate is the electron chemical gradient (electron).
a chemical gradient).

In this experiment, the application of Wayne's model was used in an experimental configuration that included the use of a gaspak anaerobic jar that depleted oxygen indoors by a chemical reaction ⁹ . A lid containing the catalyst is attached to the gas package. A gas foil foil cover containing a substance that produces hydrogen and CO ₂ is placed in a jar with a bacterial culture. Open the cover and pipet 10 ml of tap water into it. When the jar is closed (the lid is tightened tightly), the generated hydrogen combines with oxygen and forms water through the catalyst. This gradually depletes the oxygen present in the room, thus creating an oxygen gradient. In addition, the indicator strip in the jar contains methylene blue, which turns colorless in the absence of oxygen. A color change in the indicator strip indicates that proper atmospheric conditions have been achieved.

For rapid analysis of the effects of compounds on dormant bacteria, M. elegans transformed with luciferase constructs. Bovis BCG was used. M.M. Bovis BCG has been used in previous experiments as a surrogate to mimic dormancy in whole mycobacteria and specifically in Mycobacterium tuberculosis ^11,12 .

Luminescent genes from (lux A and B) are under the control of the BCG hsp60 promoter and produce light in the presence of ATP or flavin mononucleotide (FMNH ₂ ). Dead cells are unable to produce these cofactors, thus corresponding to a decrease in luminescence.

The activity of final compound 12 as well as metronidazole (met
The activity of ronidazole) and other drugs including isoniazid was analyzed. Dormant bacteria are not killed by isoniazid and are somewhat resistant to rifampicin but are susceptible to killing by metronidazole, an antibiotic for anaerobic pathogens ^15,1
6 . Isoniazid acts as initial bactericides, although its activity is limited to killing of replicating bacilli, do not have significant sterilized active to dormant bacilli ^17.

After 7 days of anaerobic life, the bacteria were suspended in drug-free medium for 5 days and the effect of various compounds on the viability of the bacteria was assessed by luciferase count. As shown in FIG. 1, isoniazid has no effect on these dormant bacteria, these bacteria have almost similar growth characteristics compared to the standard and show a dormant or non-replicating state of the cultured bacilli. Indicated. In contrast, metronidazole was clearly effective in killing dormant bacilli over a period of time, reducing it by 2 log ₁₀ compared to the standard. The final compound 12 affects the survival of dormant bacteria in a concentration dependent manner. In the final compound 12 at a concentration of 10 μg / ml, there was an approximately 4-log ₁₀ reduction in bacterial survival compared to the untreated standard.
For 0.1 and 1 μg / ml compounds, the killing of the corresponding dormant bacteria was about 0.5 log ₁₀ and 2 log ₁₀ respectively.

Final compound 12 for bacterial killing by relative luminescence units (RLU / ml)
In order to correlate the effect of γ against colony forming units (CFU / ml), bacteriocac was also measured on 7H10 plates. A similar ratio of RLU units to CFU counts was observed after plating 2 and 4 day samples on 7H10 plates. The decrease in CFU count compared to the untreated standard count is 10 μg / ml for final compound 12, 1 μ
Viability was about 4, 2.3 and 0.
5 log ₁₀ and a decrease of about 6, 4.7 and 1.1 log _{10 on the} 5th day. FIG. 2 (A and B) reports CFU data. A close relationship between luminescence and CFU was observed during the various stages of the experiment. Interestingly, there is a significant decrease in RLUs compared to CFU counts at time 0, which is mainly due to AT in these cells.
P concentration is at very low, it has been shown to be characteristic of the metabolic state of dormancy bacilli ^8.

The activity of the final compound 12 against dormant (non-proliferating) mycobacteria is a very important finding that it fights against tuberculosis by eradicating the disease in patients at risk of developing TB. Because it will help.

Research dormancy assay using Mycobacterium tuberculosis (H37RV) 1000 μl of a Mycobacterium tuberculosis stock (previously cultured) 250 m with a magnetic stir bar
100 ml Middlebrook 7H with supplements in 1 sterile Duran bottle
Added to 9 broth. Incubation was carried out on a magnetic stirrer at 37 ° C. for 7 days (500 rpm). 17 ml aliquot of log phase culture (calculated OD _600nm = 0.01)
Was transferred into a 25 ml tube. The tube was tightly closed with a cap with a rubber septum and incubated on a magnetic stir plate to produce an anaerobic life due to oxygen depletion. Agitation in the tube
This was done using an 8 mm Teflon stir bar. Anaerobic life (methylene blue (1.5mg
The tubes were incubated at 37 ° C. for 22 days in an incubator on a magnetic stir plate (120 rpm) until the color changed to colorless. After 14 days, various drugs (final concentrations of 100, 10, 1 and 0.1 μg / ml) were added to individual tubes. Metronidazole was added as a standard for killing dormant bacteria (added at the start). Isoniazid was added as a standard to show that it has no effect on the growth and viability of dormant bacteria.

CFU Assay After 22 days, cultures were collected by low speed centrifugation (2000 rpm for 10 minutes). Cells were washed twice with drug-free medium and cells were resuspended in drug-free medium and incubated. CFU compared to untreated standard cultures by plating after anaerobic life
Was determined and the bactericidal activity was assessed.

Results and discussion:
A Wayne dormancy model is used to show the effect of the final compound 12 on dormant bacteria (see FIG. 3). As already indicated above, it is an in vitro oxygen depletion model, which initiates a dormant response in bacteria ^18-23 . In the Wayne model, bacterial cultures are subjected to gradual oxygen depletion by incubation in a stirred closed tube. With the slow transition of the aerobically growing bacteria to the anaerobic state, the culture can adapt and survive more anaerobically by moving down to the state of anaerobic persistence. The Wayne model is a well-characterized in vitro model for dormancy.

In the final compound 12 at a concentration of 10 μg / ml, moxifloxacin (moxifl)
More than 2 log ₁₀ reductions in dormant bacteria were observed, as was also the case with oxacin and rifampicin. Isoniazid has no effect on dormant bacteria, but the standard compound, metranidazole, showed excellent efficacy.
