A MEDICAMENT FOR THE TREATMENT OF DISEASES BY BIOFILM FORMING MICROORGANISMS

FIELD OF INVENTION [001] The present disclosure, in general relates to the field of disease management, and in particular, relates to a medicament including a drug selected from the group consisting of acarbose, Cyclosporine A, its pharmaceutically acceptable salts thereof, and combinations thereof for the treatment of diseases caused by biofilm forming microorganisms . BACKGROUND OF THE INVENTION

[002] Mycobacterium tuberculosis is an obligate pathogenic bacterial species and the causative agent of tuberculosis. Primarily a pathogen of the mammalian respiratory system, it infects the lungs. M. tuberculosis divides every 15-20 hours, which is extremely slow compared with other bacteria. When in the lungs, M. tuberculosis is taken up by alveolar macrophages, but they are unable to digest and eradicate the bacterium. M. tuberculosis and Mycobacterium smegmatis have a strong propensity to grow in organized multicellular structures called biofilms. M. tuberculosis shares several characteristics with organisms that produce biofilms during infection. For example, infections caused by M. tuberculosis are highly persistent, show resistance to antimicrobials, and exhibit the ability to modulate the host immune system.

[003] M. tuberculosis has two peptidyl-prolylisomerase (Ppiases) PpiA and PpiB, popularly known as cyclophilin. M. tuberculosis PpiB is a surface localized glycoprotein. The M. tuberculosis PpiB gene, encoding PpiB protein, is an essential gene, which when knocked out does not allow the bacterium to survive. Expression of M. tuberculosis PpiB gene in M. smegmatis increases bacterial survivability inside macrophages (Pandey S (2016) Mycobacterium Tuberculosis peptidyl-prolylisomerase: biochemical, immunological and functional characterization. PhD Thesis -submitted to University of Hyderabad, India. It has been reported that Mycobacterial protein, the polyketide Pksl contributes to biofilm formation in M. tuberculosis (Pang et al, J. Bac. 2012, 194(3):715-21) but inhibitor against this protein is not known. It has also been reported that a chemical, TCAl reduces the biofilm formation by M. tuberculosis (Wang et al, PNAS, USA, 2013; 110(27): E2510-7) but its target has not been studied.

[004] The most frequently used diagnostic methods for tuberculosis are the tuberculin skin test, acid-fast stain, and chest radiographs. Treatment of tuberculosis frequently involves multi drug therapy (MDT) treatment. This involves taking a combination of four drugs for a period of 6-9 months, often causing toxicity to the patients. The prolonged treatment is due to the ability of this slow growing bacterium to form the biofilm which makes the bacterium drug tolerant.

[005] The development of drug resistance in this bacterium has led to the development of M. tuberculosis variants which show multi-drug resistance (MDR). This is a major issue in the treatment of the disease and there is now a need to identify alternative drugs for the treatment of tuberculosis.

Experiment 1

Biofilm formation assay

[00216] M. tuberculosis PpiB is a glycosylated protein which has a potential lipid modification site (lipobox motif). The biofilm forming potential of overexpressed M. tuberculosis PpiB in M. smegmatis (Ms_PpiB) was compared with M. smegmatis containing empty vector (Ms_VC) (Figure 1). Biofilm formation in M. smegmatis (Ms_PpiB) was induced by culturing M. smegmatis cells, overexpressing M. tuberculosis PpiB under an anhydrotetracycline inducible promoter. M. smegmatis (Ms_VC) cultured in absence (VC Tet-) or presence (VC Tet+) of anhydrotetracycline or M. smegmatis cultured in absence (Ms_PpiB Tet-) of anhydrotetracycline were used as control and compared against biofilm formed in M. smegmatis cultured in presence of anhydrotetracycline (Ms_PpiB Tet+). Briefly, M. smegmatis was cultured in Middlebrook 7H9 agar broth supplemented with 10% Middlebrook OADC, henceforth referred as 7H9 media. Protein expression was induced by addition of 20 ng/ml of anhydrotetracycline and cells were incubated for 48hours. The culture was then diluted to an OD of 0.08 in 7H9 media and pipetted in each well of a 96-well microtitre plate. For further studies in this disclosure, various concentrations of different biofilm inhibitors (cyclosporine A and acarbose) were added into each well of a 96-well microtitre plate, in addition to anhydrotetracycline. The plates were then covered and incubated at 37 °C for 7 days. After incubation, the content of the wells was aspirated out and stained by adding 125 μΐ of 0.1% Crystal Violet (w/v) solution to each well. Each well was then washed thrice with water followed by addition of 30% acetic acid. The plates were subsequently incubated for 10 to 15 min. at room temperature and absorbance was taken at 550 nm.

[00217] The biofilm assay was extrapolated to assess the effect of cyclosporine A on M. tuberculosis H37Rv strain. Briefly, H37Rv cells were inoculated at an OD=0.6 through the walls of the test tube containing 7H9 media. The test tube containing control and Cyclosporin A (100μg/ml) were incubated undisturbed in static phase for 4 weeks. The pellicle formed at the liquid air interface was evaluated for biofilm formation.

[00218] As is illustrated in Figure 1, PpiB overexpressing M. smegmatis (Ms_PpiB) exhibited enhanced biofilm and pellicle formation, as compared to PpiA over expressing M. smegmatis (Ms_PpiA) and M. smegmatis containing empty vector (Ms_VC). This indicates that M. tuberculosis PpiB is a protein involved in biofilm formation.

[00219] As is illustrated from Figure 14, Mycobacterium H37Rv treated with cyclosporine A (100μg/ml) exhibited reduced pellicle formation, as compared to control cells. This indicates that Cyclosporin A suppresses biofilm formation in H37Rv cells. Experiment 2

Effect of cyclosporine A and acarbose on the viability of M. smegmatis over- expressing M. tuberculosis PpiB protein

[00220] The effect of cyclosporine A and acarbose on the viability of M. smegmatis over-expressing M. tuberculosis PpiB under tetracycline inducible promoter was scored using colorimetric alamar blue staining as described elsewhere (Taneja et al. J

Antimicrob Chemother 2007;60(2): 288-293). M. smegmatis cells, in log phase were induced with anhydrotetracycline, cultured for 24 hours and cells from secondary culture

43 of bacteria were seeded in a 96 well plate at an initial OD of 0.08 in 7H9 media. Cells were incubated with/without anhydrotetracycline in presence of various concentration of cyclosporine A or acarbose. After 68 hours, alamar blue reagent was added to the cells and incubated for an additional 3-4 hours. Viability was measured as the variance between absorbances at 570 nm and 600 nm. Blanks for spectrophotometry were provided by wells containing medium alone and alamar blue. All assays were performed in triplicate.

[00221] At 500 μg/ml and above, cyclosporine A significantly inhibited the viability of M smegmatis, and this effect was much enhanced in PpiB cultures treated with anhydrotetracycline (Tet+) as compared to the controls without anhydrotetracycline (Tet ) (Figure 2).

[00222] Further, Figure 3 shows that up to 1 mg/ml concentration of acarbose did not have any effect on the viability of M. smegmatis cells either expressing M. tuberculosis PpiB (PpiB Tet +) or vector control (VC Tet+). Experiment 3

Effect of cyclosporine A and acarbose on PpiB mediated biofilm formation in M. smegmatis over-expressing M. tuberculosis PpiB protein

[00223] In order to examine the inhibitory role of cyclosporine A or acarbose on biofilm formation, M. smegmatis was cultured in presence of various concentrations of cyclosporine A or acarbose as described above. After 7 days, cells were removed and the biofilm formed at the solid liquid interface was stained using 0.1% solution of crystal violet for 10-15 minutes, as described elsewhere (O'Toole J Vis Exp 2011 ;47:2437). Crystal violet was dissolved in 30% acetic acid and quantified colorimetrically at 550 nm as an estimate of the biofilm formed.

[00224] As illustrated in Figure 4, anhydrotetracycline induced PpiB led to greater formation of biofilm in PpiB expressing M. smegmatis (Ms_PpiB Tet+) as compared to PpiB uninduced (Ms_PpiB Tet-) or in Vector control (Ms_VC Tet-/Tet+). Treatment with cyclosporine A above 10(^g/ml significantly reduced biofilm formation in Ms_PpiB (Tet+). cyclosporine A could therefore bind to PpiB and inhibit the activity of PpiB which in turn reduces biofilm formation.

[00225] Additionally, as depicted in Figure 5, there is a significant inhibition in the biofilm formation above 500 μg/ml of acarbose treatment in anhydrotetracycline induced-PpiB overexpressing M. smegmatis cells (Ms_PpiB Tet+) as compared to M. smegmatis containing empty vector (Ms_VC). Each experiment was performed three times independently and statistical analysis was done using one-way Anova.

[00226] Thus, both acarbose and cyclosporine A can inhibit biofilm formation in M. smegmatis overexpressing M. tuberculosis PpiB protein.

Experiment 4

Effect of isoniazide and ethambutol on survival of M. smegmatis in the presence and absence of cyclosporine A or acarbose

[00227] Biofilm formation contributes to increased drug tolerance. In order to examine the effect of cyclosporine A or acarbose on biofilm mediated drug tolerance in M. smegmatis, cells were incubated either in the absence or presence of cyclosporine A or acarbose and biofilm formation assay was performed as described previously. At the end of 7 days of culture, cells were treated with isoniazide (0, 8, 16, 32, 64 μg/ml) or ethambutol (0, 0.25, 1, 4. 16μg/ml) for additional 72 hrs. The viability of cells was assessed using alamar blue reagent. Results in Figure 6 indicate that PpiB -induced biofilm increases the tolerance of M. smegmatis towards isoniazide. The minimum inhibitory concentration (MIC) of isoniazide in absence of cyclosporine A was 16μg/ml for VC(tet-/tet+) and PpiB (tet-) cultures whereas it was 64μg/ml in PpiB (tet+) suggesting that PpiB induced biofilm increases the tolerance of M. smegmatis towards isoniazide. The MIC of isoniazide in the presence of cyclosporine A treatment was 8μg/ml for VC(tet-/tet+) and PpiB (tet-) cultures whereas it was 32μg/ml in PpiB (tet+) suggesting the role of cyclosporine A on reducing biofilm formation which in turn increases the susceptibility of M. smegmatis towards isoniazide. Similar results were observed with ethambutol in presence of cyclosporine A. As seen in Figure 7, ethambutol inhibits PpiB (Tet+) culture in the absence of cyclosporine A treatment at 4μ^ιτι1 and this effect was enhanced in the presence of cyclosporine A.

[00228] Similar to the results obtained above, the MIC of isoniazide in the absence of acarbose was 16μg/ml for VC (Tet+) and 64μg/ml for PpiB (Tet+) cells. As depicted in Figure 8, in the presence of acarbose, MIC of isoniazide decreased to 32μg/ml for PpiB (Tet+), thus proving that the effect of acarbose on biofilm reduction consequently reduces the tolerance of M. smegmatis towards isoniazide.

[00229] These results propose both cyclosporine A and acarbose as leading compounds to support anti-TB drugs to reduce the MIC in MDR tuberculosis in combination with either isoniazid or ethambutol.

Experiment 5

In silico interaction study of PpiB with US FDA approved drugs [00230] Crystallographic structure of PpiB is not present at Protein Data Bank so it was modelled through Phyre2 server (Kelley et al, Nat Protocols, 2015; 10, 845-858) . Protein sequence of PpiB of M. tuberculosis (strain ATCC 25618 /H37Rv) was obtained from UniprotKB database [P9WHW1] (Consortium U, Nucleic Acids Research, 2014; D204-12). Molecular dynamics (MD) was performed for the modelled structure through GROMACS v5.0 (Abraham et a/,GROMACS User manual, 2014) using OPLS2005 force field. Firstly, the modelled protein structure was solvated into a triclinic box using spc water model. Then, the system was neutralized, energy minimized as well as equilibrated through NVT and NPT ensemble then well equilibrated system was processed to production run of MD for 40 nanoseconds (ns). Protein structure model validation was done through protein structure validation software suite (PSVS)

(Bhattacharya et al, Proteins: Structure, Function, and Bioinformatics, 2007; 66: 778-

95) that includes the large set of quality and constraint analysis. It includes the stereochemical quality analysis and model compatibility with own amino acid sequence through Verify_3D (Luthy et /,Nature,1992; 356(6364):83-5; Eisenberg et al, Methods Enzymol.,1997; 277:396-404). and all-atom contact and covalent geometry analysis through MolProbity (Chen et al, Acta crystallographica D,2010; 66(Pt 1): 12-21). Representative frame was selected from the simulation trajectory for docking analysis.

[00231] Docking study of the PpiB protein with acarbose and other FDA approved drugs was performed through Glide module of Schrodinger (Schrodinger et al, LLC, New York, USA, 2009). For this the protein structure was prepared through Protein preparation wizard. Protein was pre-processed by assigning bond orders, adding hydrogen, deleting water molecules further than 5A distance as well as converting all selenomethionines to methionines. Uncapped N and C termini were capped by ACE (N- acetyl) and NMA (N-methyl amide) respectively. Hydrogen bond assignment was done using ProtAssign that optomizes hydroxyl, Asparagine, Glutamine and Histidine states. Impref minimization was done using 0.30A RMSD and OPLS 2005 force field.

[00232] For PpiB ligand binding studies and identification of possible inhibitors of PpiB, the approved drugs were prepared through LigPrep module of Schrodinger suite using OPLS2005 force field. All possible states at pH 7+/- 2 were generated using ionizer and retaining specific chiralities of the molecules. At most, 32 ligands were generated per ligand molecule and the output was saved in maestro format for the docking purpose.

[00233] The active site residues were selected on the basis of prediction through 3D Ligand site server that performs the model based as well as the sequence based prediction. Both strategies were used to get the active site residues i.e. Prol35, Asn223 and Pro225. Confirmation of docking accuracy was also carried out using another platform AutoDock Tools (Morris et al, J Comput. Chem., 2009; 30(16): 2785-2791.) and inhibition constants were also estimated.

[00234] PpiB amino acid sequence was submitted to Phyre2 and intensive mode was chosen for model building as it uses multiple templates and ab-initio techniques. The modeled structure was found having an overall 98% residue in the allowed regions. Global quality Z-score values for MolProbityClash score is recommended to be greater than -3 for high quality structures, and our model scored -1.23, suggesting an adequate model. Verify3D also corroborated the reasonable quality of the model. Thus, the PpiB model satisfied the structure quality parameters of an acceptable protein structure model.

[00235] The structure obtained from the server was processed for molecular dynamics simulation to get a stable starting structure for molecular docking studies. RMSD analysis for the PpiB protein showed a stable trajectory from 20ns to 40ns with small deviations in the range of 0.2nm (Figure 9). The starting structure from the 40000 ps trajectory was obtained through cluster analysis using GROMACS by gromos method (Daura et al, Proteins: structure, function, and bioinformatics, 1999; 34: 269-280). Figure 10 shows a superimposition of Pre-MD and Post-MD PpiB protein models.

[00236] Docking was performed in two steps i.e. HTVS (high throughput virtual screening) (Sastry et al, J Comput Aided Mol Des, 2013; 27: 221 ) and XP (extra precision) docking (Friesner et al, J. Med. Chem., 2006; 49(21), 6177-6196). HTVS docking method filtered out the compounds with low binding energy (Singh et al, Structural Chemistry, 2015; 27: 993-1003). HTVS docking method filtered out the compounds with low binding energy. The compounds having a docking score greater than -5 in HTVS were used for XP docking protocol. An XP score greater than -8 showing strong binding was displayed by many of the USFDA approved drugs and this is given in Table 1.

Table 1 [00237] Molecular docking carried out using alternate platform also confirmed high binding energies of acarbose with PpiB. Estimated inhibition constant (Ki) was found in the range of 16-20 μΜ for acarbose. The interaction plot of the drug withPpiB protein was made using LigPlot ^"1" software and represented in Figure 1 1 (Laskowski et al, J. Chem. Inf. Model., 2011 ; 51(10):2778-86). These results provide interesting leads with respect to USFDA approved drugs for their likely value in acting as inhibitors of PpiB, which is associated with enhancement in biofilm formation and by corollary in rendering the pathogen more responsive to drugs.

[00238] Molecular dynamics simulations of the PpiB docked complexes with acarbose were also performed using GROMACS v5.0 assigning GROMOS96 (van Gunsteren et al, The {GROMOS96} manual and user guide 1996) 43 a 1 force field. GOMACS topology for the ligand was generated using the PRODRG (Schuettelkopf et al, Acta CrystalClographica , 2004; D60, 1355-1363). Docked complexes of PpiB with both the drugs were solvated in a triclinic water boxes using spc water molecules, genion tool was used to make the systems electrically neutral. Systems were subjected to energy minimization by steepest descent method for 50000 nssteps. MD simulation for the complexes was performed in two steps i.e. first the systems were equilibrated and then the production run was carried out. Initially NVT (isothermal-isochoric) and then NPT (isothermal-isobaric) equilibration was done in continuation to stabilize the temperature and pressure of the systems, respectively. Both the equilibration steps were performed for 50ps time. After attaining the desired temperature and pressure, systems were proceeded for MD production run of lOOOOps/lOns to attain stable trajectories of the complexes.

[00239] After completion of the 10ns molecular dynamics the trajectories were analysed. First the trajectories were made compact, protein and ligand complexes were centered to the solvation box and fit analysis was also done with reference to the starting structure. MD trajectory after the fit analysis was used for further analysis of the docked complex structures. RMSD analysis for the complex trajectories was done using GROMACS. It shows the stable trajectory for PpiB-Acabose complex from 6- 10ns with minimal fluctuations in acceptable range as shown in Figure 12. Representative structures from the stable trajectories were extracted using the cluster analysis approach and the hydrogen and hydrophobic interactions were plotted. Both the complexes show new interactions after MD while retaining few pre-MD interactions represented in Figure 13.

In silico molecular docking analysis of M. tb PpiB

[00240] The In silico molecular docking analysis of M. tb PpiB in complex with cyclosporine A was carried out to study the interactions and affinity of compound cyclosporine A with the protein PpiB. The protein structure model of M. tb PpiB was generated by homology modelling technique using the MODELLER version 9.1 1 (Fiser and Sali, Methods Enzymol 2003: 374: 461-91). The 3D structure of cyclosporine A was obtained from chemical structure database ChemSpider (Pence et al, J. Chem. Educ. 2010; 87( 11): 1123-1 124). Polar hydrogens were added, non-polar hydrogens were merged and computation of Gastegier partial charges was carried out (Gasteiger and Marsilli, 1980; doi: 10.1016/0040-4020(80)80168-2) for the protein structure using Autodock Tools 1.5.6 (ADT) package (Morris et al., J Comput Chem 2009; 30(16):2785- 2791 before embarking docking analysis. The program AutoDockVina 1.1.2 (Trott and Olson, J Comput Chem 2010; 31(2):455-461) was used for further docking of cyclosporine A at the catalytic active site of PpiB protein. The location of the catalytic site was mapped and deduced from the structure based alignment of related proteins reported earlier (Henriksson et al., Eur J Biochem 2004; 271(20):4107-13). The Argl84 conserved residue from the catalytic centre was used for docking analysis and therefore it was assumed that this protein-drug complex may represent a real entity. Docked complex of protein-ligand was then energy minimized using the GROMACS, version 4.6.5 (Abraham et al., 2015; doi/10.1016/j.softx.2015.06.001 under OPLS-AA force field for optimising the correct conformation of binding mode and stability of the protein-ligand complex. Ligplot (Laskowski and Swindells, J Chem Inf Model 2011) was used for the visualization of the interactions between protein-ligand complex in two- dimensional schematic representations and the program PyMol (www.pymol.org) was used for the preparing cartoon representations of the structures. Results in Figure 15A and 15B show multiple interactions between cyclosporine A and M. tb PpiB.

[00241] Molecular docking studies of cyclosporine A binding sites in all PpiB homologues expressed in different biofilm forming bacteria were compared. Results in Figure 16 show that M.tb PpiB (Rv2582) exhibits homology with proteins from other biofilm forming bacteria and possess similar amino acids at binding site of cyclosporine A.

[00242] The results demonstrate that Argl84 residue from PpiB, is conserved across the homologous proteins, in some of the cases it is present at different positions. The position of conserved Arginine residue present in different groups of biofilm forming microorganisms, listed in Table 2, in terms of gene bank accession numbers: WP_061736025.1, WP_049374178.1, WP_019168288.1, WP_019320573.1, WP_048792681.1, WP_006270079.1, CRQ97127.1 are Arg59, Arg59, Arg59, Argl07, Arg59, Arg327 and Arg46, respectively. Molecular docking studies of acarbose binding sites in all PpiB homologues expressed in different biofilm forming bacteria were compared. Results in Table 2 show that acarbose could bind to all homologous PpiB proteins expressed in different biofilm forming bacteria, listed in Table 2. Pro63 in M. tb is conserved for acarbose binding in WP_061736025.1, WP_019168288.1, and WP_019320573.1. In WP_048792681.1, WP_006270079.1 and CRQ97127.1 exhibited a nearby Pro33 residue to compensate the binding affinity (Table 2). Presence of conserved amino acids at the cyclosporine A or acarbose binding site in PpiB homologues of several biofilm forming bacteria indicate that the active site of PpiB have largely remained unaltered and hence could prove to be an excellent putative target across bacterial species.

Amino acid sequence analysis

[00243] The amino acids sequences of M. tb PpiA (GenBank Accession number: CCP42731.1), M. tb PpiB (GenBank Accession number: CCE38048.1), E. coli peptidyl proliyl isomerase (GenBank Accession number: EDV66960.1) and peptidyl -prolyl isomerase RopA (trigger factor) of Streptococcus mutans (GenBank Accession number: AAN57875.1) were downloaded from the National Center for Biotechnology Information (https://www.ncbi.nlm.nih.gov). To examine the difference in sequences of M. tb PpiB with other peptidyl prolylisomerses M. tb PpiA and E. coli peptidyl proliyl isomerase, multiple sequence alignment of these sequences was done using MULTIALIN algorithm (Corpet, Mucleic Acid Res. 1988; 16(22);10881-10890). To examine the similarity of M. tb PpiB with the peptidyl-prolylisomerase (trigger factor) involved in biofilm formation, multiple sequence alignment of amino acids sequence of M. tb PpiA, M. tb PpiB and RopA was carried out. The sequence homology search of M. tb PpiB was done using BLASTp in known biofilm forming bacteria such as Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus intermedius, Streptococcus mutans, Staphylococcus saprophyticus, Streptococcus constellatus on NCBI website. M. tb PpiB amino acids sequence was used as queries in BLASTp analyses against the NCBI non-redundant protein database of the specific bacteria to find their similar homologues.

[00244] Results in Figure 17 A show that M. tb PpiA or PpiB exhibit high degree of similarity in conserved amino acids found in E. coli Ppiase. M. tb PpiB also possesses an extended sequence of 100 amino acids in the N terminal end and is absent in either M.tb PpiA or E. coli Ppiase. Results in Figure 17B show that, M. tb Ppiase exhibit high degree of sequence similarity with trigger factor proteins (RopA) expressed in S. mutans. Previous studies provided evidence that M. tb PpiB possess chaperonic acivity and plays crucial role in protein stability and protein folding (Pandey et al., PloS One 2016; 1 l(3):el50288). The importance of chaperons in aiding biofilm formation in S. mutans is already known. By virtue of the fact the M. tb PpiB bears high degree of similarity in amino acid sequence of S. mutans RopA proteins, it was speculated that M. tb PpiB may be involved in biofilm formation. The homologs of M. tb PpiB are also present in several well-known pathogenic bacteria such as Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus intermedius, Streptococcus mutans, Staphylococcus saprophyticus, Streptococcus constellatus, Pseudomonas aeruginosa that are known to make biofilm. Experiment 8

In vitro physical interaction of M. tb PpiB with cyclosporine A and acarbose [00245] The in vitro physical interaction of M. tb PpiB with cyclosporine A and acarbose was studied using surface plasma resonance (SPR) technique using Autolab ESPRIT analyzer. The experiments were performed according to manufacturer instructions. Briefly, M. tb PpiB was diluted in PBS upto a concentration of 10C^g/ml and passed through a CM5 sensor chip for immobilization. For purified rPpiB, M.tb PpiB was cloned in pGEX-6p-l vector and expressed in E. coli BL21(DE3) rosetta strain for protein purification, as described previously (Pandey et al., 2016). During association phase (300seconds) cyclosporine A (10, 100, 250, 500ug/ml) or acarbose (upto 1000μΜ) was diluted to different concentration in running buffer (PBS) and were allowed to pass over the immobilized PpiB. During dissociation phase (150 seconds) PBS was applied to sensor chip and the sensor chip was regenerated between each binding experiment with NaOH.

[00246] cyclosporine A binds to cyclophilins and inhibits its activity (Mitra et al 2006). Results of SPR analysis show that cyclosporine A (Figure 18A) or acarbose (Figure 18B) interacts with M. tb PpiB in a dose dependent manner and bind with high affinity. Table 3 shows Docking parameters of cyclosporine A in complex with mycobacterial cyclophilin PpiB. The binding energy value of cyclosporine A with PpiB as - 5.2Kcal/mol, indicative of the high affinity binding of PpiB with cyclosporine A.

Table 3

[00247] These results suggest that cyclosporine A or acarbose, by virtue of their ability to bind to PpiB, could modulate the activity of PpiB. It was therefore speculated that modulation of PpiB activity upon binding with cyclosporine A or acarbose could affect biofilm formation per se, that in turn could enhance penetrance of drugs across biofilms, thereby lowering the MIC values of drugs and also survival of the bacteria.
