- sodA is a virulence factor
- otsA and fpbC are important for bacterial metabolism and division
- the lsr2 gene that encodes the Lsr2 protein. The only gene whose expression does not increase as a result of administering
- Zafirlukast was sigA.
- the expression of the lsr2 gene has increased 8.8 fold; to compensate for the decreased ability of the Lsr2 protein to bind DNA in the presence of the drug.
- Figure 5 A plot of polarization versus concentration of Lsr2 demonstrating an increase in polarization corresponding to the Lsr2/DNA complex formation. The concentration of Lsr2 was increased until saturation was reached. From fitting of the normalized data, the K d for the Lsr2-DNA complexation was determined to be 0.87 ⁇ ⁇ 0.09 (R 2 0.961).
- Figure 7 Spectra from the Intensity Fading experiment comparing the relative ion intensities of Zafirlukast and Ritonavir. As the concentration of Lsr2 is increased from top to bottom, the relative intensity of Zafirlukast diminishes as compared to the internal standard (Ritonavir). The decrease in relative intensity is attributed to complexation between Lsr2 and Zafirlukast.
- Figure 8 Plot of the intensity ratio of Zafirlukast (Z) over Ritonavir (R) versus the concentration of Lsr2. As the concentration of Lsr2 is increased a larger portion of the
- Zafirlukast is bound to the protein decreasing the amount of free ion to be ionized, thus decreasing the intensity of the Zafirlukast signal.
- the term “tuberculosis” comprises disease states usually associated with infections caused by mycobacteria species comprising M. tuberculosis (M.tb.) complex.
- the term “tuberculosis” is also associated with mycobacterial infections caused by mycobacteria other than M. tuberculosis (MOTT).
- mycobacterial species include M. avium- intracellulare, M. kansarii, M. fortuitum, M. chelonae, M. leprae, M. africanum, and M. microti, M. avium paratuberculosis, M. intracellulare, M. scrofulaceum, M. xenopi, M. marinum, M.
- the tuberculosis is multidrug-resistant tuberculosis (MDR tuberculosis) or extensively drug-resistant tuberculosis (XDR tuberculosis).
- MDR tuberculosis means a form of tuberculosis that is resistant to two or more of the primary drugs (e.g., isoniazid and rifampicin) used for the treatment of tuberculosis.
- the present invention is based, at least in part, on the discovery that Lsr2 binds more than 20% of the genes identified in the M. tb genome.
- Lsr2 is a nucleoid-associated protein found in M. tb as well as in other actinobacteria.
- Lsr2 appears to be functionally analogous to eukaryotic histone proteins as well as the H-NS nucleoid-associated proteins found in E. coli and related gammaproteobacteria.
- Lsr2 binds AT-rich DNA to promote DNA condensation and structural organization of the genome. While not wishing to be bound by theory, the inventors herein now believe that a consequence of this function is that Lsr2 binds promoter regions in the GC-rich mycobacterial genome and thereby acts as a global repressor of transcription.
- M. smegmatis a common non-pathogenic surrogate for M. tb as well inhibiting the growth of M. tb.
- the infection is caused Corynebacterium diphtheriae and Corynebacterium pseudotuberculosis as well as other Corynebacterium sp, including, but not limited to: species Corynebacterium diphtheriae and the nondiphtherial corynebacteria, collectively referred to as diphtheroids; Corynebacterium haemolyticum (Arcanobacterium haemolyticum); Corynebacterium jeikeium; Corynebacterium glutamicun; Corynebacterium pseudodiphtheriticum.

- Nondiphtherial corynebacteria also cause chronic and subclinical diseases in domestic animals and can lead to significant economic losses for farmers.
- Examples of widespread and difficult-to-control infections include Corynebacterium pseudotuberculosis caseous lymphadenitis in sheep, goats, and alpacas; C. pseudotuberculosis ulcerative dermatitis in cattle; and urinary tract infections and mastitis (affecting milk production) in cattle due to infection with Corynebacterium renale, Corynebacterium cystidis, Corynebacterium pilosum, and Corynebacterium bovis.
- Specific pathogenic groups or species include the following:
- Corynebacterium ulcer ans C pseudotuberculosis (also known as Corynebacterium ovis);
- Corynebacterium pyogenes A haemolyticum; Corynebacterium aquaticum; C
- pseudodiphtheriticum also known as Corynebacterium hofinannii
- Group D2 also known as Corynebacterium urealyticum
- Group E also known as Corynebacterium urealyticum
- Cjeikeium ie, group JK
- the inhibitor screening methodology used a preincubated Lsr2/DNA complex where the Lsr2 concentration was chosen to be above the Kd value to ensure that the assay was both sensitive and discriminating.
- the assay was used to screen a portion of the NIH Clinical Collection (BioFocus, Saffron Walden, UK). Of the 281 compounds tested, seven compounds were identified as potential leads based on a criterion of an FP signal decrease greater than three times the standard deviation from the mean polarization measurement. Of these indentified inhibitors, six are known DNA intercalators or groove binders so they were dismissed from further study. Although compounds with these attributes have been previously used to disrupt protein/DNA complex formation they are also known for their lack of specificity and severe side effects when used therapeutically.
- Zafirlukast is a leukotriene receptor antagonist commonly prescribed as a prophylactic treatment for asthma.
- a dose-dependence study using the same FP-based assay was used ( Figure 1).
- the protein and DNA concentrations were held constant at 50 ⁇ and 10 nM, respectively, as the concentration of Zafirlukast was varied.
- Zafirlukast inhibits complexation by binding Lsr2 and not DNA.
- Zafirlukast is also supported by the chemical structure of Zafirlukast, in that it is not a polycyclic aromatic compound and that it is anionic at physiological pH. For example, see the structures shown in Figure 4.
- Zafirlukast is binding Lsr2 and not DNA
- an Intensity Fading MALDI-TOF mass spectrometry assay was performed. This methodology is advantageous when attempting to show non-covalent binding of inhibitors possessing limited solubility, like Zafirlukast, to their protein targets. Samples containing fixed concentrations of Zafirlukast and Ritonavir, as an internal standard, were titrated with increasing concentrations of Lsr2.
- Zafirlukast does inhibit mycobacterial growth and the radius of the zone of inhibition is directly correlated to the amount of Zafirlukast on the respective discs. In contrast, the same amount of compound in a similar experiment using E. coli exhibited no growth inhibition
- RT-PCR Real-Time PCR
- sigA As sigA is constitutively expressed at a constant level in cultured bacteria, transcription of this gene is unlikely to respond to only a single signal.
- the regulatory factors present in response to the stress imparted by administering Zafirlukast likely supersedes the effect of inhibiting Lsr2 function or the subsequent increase in Lsr2 concentration as a consequence of its over expression.
- Zafirlukast specifically inhibits Lsr2 function in mycobacterial cells.
- the present inventors herein identified compounds that inhibit the activity of the highly conserved DNA-binding protein Lsr2. Not only is Zafirlukast now identified as an inhibitor of Lsr2 function, but the application of this drug also alters gene expression levels in M. tb and leads to growth inhibition of mycobacteria presumably by profoundly dysregulating protein expression levels in the bacterial cell.
- Zafirlukast has synergistic effects with other first-line drugs since Lsr2 expression increases during the administration of known anti-tubercular drugs presumably to help M. tb survive during pharmacologically-induced stress.
- Lsr2 is clearly important for the mycobacterial response to environmental stress, the efficacy of Zafirlukast may be greater in the host by disrupting defenses evolved in M. tb. to evade or disrupt the human immune response. This may promote killing of M. tb by the human immune system.
- Zafirlukast does not appear to function through the same mechanism of any current TB drugs, so it is likely to be effective against XDR-TB.
- Zafirlukast is an approved, safe, orally available drug that is readily transported to lung tissue, repurposing it for the treatment of TB could have an immediate impact on global health.
- Zafirlukast was purchased from Sigma-Aldrich.
- 5'-fluoroscein labeled AT-rich stem-loop DNA with the sequence 5'- CCTAATTATAACGAAGTTATAATTAGG-3' [SEQ ID NO:l] was purchased from Integrated DNA Technologies (Coralville, IA) and dissolved in deionized water at a concentration of 100 ⁇ , heated to 95°C for 15 minutes, cooled on ice, and stored at -20°C until needed. All mass spectrometry experiments were carried out on a Bruker ultrafleXtreme MALDI TOF/TOF.
- Lsr2 from recombinant DNA was expressed in E. coli BL21 (DE3) using Luria- Bertani (LB) media. The culture was grown at 37°C until reaching an O.D. 6 o 0 mn between 0.6 and 0.8 followed by induction with IPTG at 16°C for 36 hours. Lsr2 was purified using immobilized metal affinity chromatography followed by cation exchange chromatography.
- the K d was obtained using a 384-well microplate format fluorescence polarization (FP) assay performed at 37°C. Each well contained 1 ⁇ ⁇ of fluorescently labeled DNA (10 nM) and concentrations of Lsr2 ranging from 0 to 200 ⁇ . Additional buffer solution (20 mM Tris pH 7.5, 50 mM NaCl) was added as needed to reach a final volume of 25 ⁇ ⁇ .
- FP fluorescence polarization
- the NCC was screened in a corning 384-well microplate at 37°C with an excitation of 485 nm and an emission of 528 nm.

- Controls were also performed by adding 1 ⁇ of DMSO lacking drug.
- the FP signals were evaluated for each tested drug. Any compound showing a decrease in the FP signal that was greater than three times the standard deviation was considered a hit.
- the 3 ⁇ 4 was obtained using the same FP assay format. Each well contained 1 ⁇ of fluorescently labeled DNA (10 nM), 20 ⁇ of Lsr2 (50 ⁇ ) and the concentration of Zafirlukast was varied by adding a constant volume (1 ⁇ ) with increasing concentrations, from 0 to 300 ⁇ . Kj was calculated with Prism (GraphPad software) using the equation
- M. smegmatis with Ampicillin was grown at 37°C for 72 hours in Middlebrook 7H9 Broth.

- Zafirlukast 392 ⁇ g, 196 ⁇ g, 95 ⁇ g, 50 ⁇ g, 0 ⁇ g in 20 ⁇ . of DMSO
- the agar plate was incubated for 14 hours at 37°C then the zones of inhibition were examined.
- the analogous experiment using E. coli in LB media was performed using the same protocol.
- the Kirby-Bauer disk diffusion assays were performed in a similar manner using M. tb. However, growth at 37°C was for 10 days because of the much longer doubling time exhibited by M. tb.
- the nonbinding internal standard, Ritonavir was diluted to a concentration that gave a MALDI MS ion signal of intensity that resembled that of the Zafirlukast.
- the compounds were both dissolved in DMSO, combined and diluted with a 20 mM Tris pH 8.5 solution. From this solution 2 ⁇ were added to each of the solutions containing increasing concentration of Lsr2 in 20 mM Tris pH 8.5. The solutions were then incubated at 4 °C for 12 hours. The sample was mixed using the dried droplet method with a matrix solution (1:2 v/v) of sinapinic acid
