Abstract
Tuberculosis, caused by Mycobacterium tuberculosis (M. tb), remains a significant global health challenge. The survival of M. tb in hostile extracellular and intracellular microenvironments is crucial for its pathogenicity. In this study, we discovered a Bacillus Calmette-Guérin (BCG) mutant B1033 that potentially affected mycobacterium pathogenicity. This mutant contained an insertion mutation gene, fadD33, which is involved in lipid metabolism; however, its direct role in regulating M. tb infection is not well understood. Here, we found that the absence of fadD33 reduced BCG adhesion and invasion into human pulmonary alveolar epithelial cells and increased the permeability of the mycobacterial cell wall, allowing M. tb to survive in the low pH and membrane pressure extracellular microenvironment of the host cells. The absence of fadD33 also inhibited the survival of BCG in macrophages by promoting the release of proinflammatory cytokines, such as interleukin (IL)-1β, IL-6, and tumors necrosis factor-α, through the mitogen-activated protein kinase p38 signaling pathway. Overall, these findings provide new insights into M. tb mechanisms to evade host defenses and might contribute to identifying potential therapeutic and vaccine targets for tuberculosis prevention.

Abstract
In recent years, vaping has increased in both popularity and ease of access. This has led to an outbreak of a relatively new condition known as e-cigarette/vaping-associated lung injury (EVALI). This injury can be caused by physical interactions between the pulmonary surfactant (PS) in the lungs and toxins typically found in vaping solutions, such as medium chain triglycerides (MCT). MCT has been largely used as a carrier agent within many cannabis products commercially available on the market. Pulmonary surfactant ensures proper respiration by maintaining low surface tensions and interface stability throughout each respiratory cycle. Therefore, any impediments to this system that negatively affect the efficacy of this function will have a strong hindrance on the individual's quality of life. Herein, neutron spin echo (NSE) and Langmuir trough rheology were used to probe the effects of MCT on the mechanical properties of pulmonary surfactant. Alongside a porcine surfactant extract, two lipid-only mimics of progressing complexity were used to study MCT effects in a range of systems that are representative of endogenous surfactant. MCT was shown to have a greater biophysical effect on bilayer systems compared to monolayers, which may align with biological data to propose a mechanism of surfactant inhibition by MCT oil.

Spiropyrimidinetriones: a Class of DNA Gyrase Inhibitors with Activity against Mycobacterium tuberculosis and without Cross-Resistance to Fluoroquinolones.

Abstract
Described here is a series of spiropyrimidinetrione (SPT) compounds with activity against Mycobacterium tuberculosis through inhibition of DNA gyrase. The SPT class operates via a novel mode of inhibition, which involves Mg2+-independent stabilization of the DNA cleavage complex with DNA gyrase and is thereby not cross-resistant with other DNA gyrase-inhibiting antibacterials, including fluoroquinolones. Compound 22 from the series was profiled broadly and showed in vitro cidality as well as intracellular activity against M. tuberculosis in macrophages. Evidence for the DNA gyrase mode of action was supported by inhibition of the target in a DNA supercoiling assay and elicitation of an SOS response seen in a recA reporter strain of M. tuberculosis. Pharmacokinetic properties of 22 supported evaluation of efficacy in an acute model of M. tuberculosis infection, where modest reduction in CFU numbers was seen. This work offers promise for deriving a novel drug class of tuberculosis agent without preexisting clinical resistance.

Abstract
Fluoxetine (FLX), approved for the treatment of depression and anxiety by the FDA in 2002, is an amphiphilic antidepressant. In general, amphiphilic drugs have high membrane permeability. Therefore, the interactions between these drugs and monolayers have been widely concerned. In this study, the adsorption of FLX on dipalmitoylphosphatidylcholine (DPPC) monolayers at different concentrations and surface pressures have been investigated by pressure-area isotherms (π-A), adsorption curves, compression-expansion curves, and atomic force microscopy (AFM). Our data showed that the adsorption behavior was related to the surface pressures and FLX concentrations in the subphase. The FLX that was added in the subphase under lower surface pressure (π = 10 mN/m) was easily adsorbed on DPPC monolayers. The stability of the monolayers was strong. The adsorption of FLX on DPPC monolayers and the stability decreased when π = 20 mN/m. In addition, the adsorption behavior and stability increased with increasing FLX concentrations. The AFM images of the monolayers confirmed the results of fitted adsorption curves. This study will be critical to our understanding of the interactions between drugs and lipid monolayers.

Study of the Mechanism of the Antimicrobial Activity of Novel Water Soluble Ammonium Quaternary Benzanthrone on Model Membranes. J Membr Biol 2020; 253:247-256.

Abstract
The increasing resistance of many pathogens to most of the common antimicrobials requires the development of new substances with more effective antimicrobial properties. In the present work, we investigated the mechanism of the antimicrobial activity of novel water soluble ammonium quaternary benzanthrone (Compound B) on model membranes, composed of dipalmitoylphosphatidylcholine, 1-palmitoyl-2-oleoylphosphatidylcholine, dipalmitoylphosphatidylglycerol, 1-palmitoyl-2-oleoylphosphatidylglycerol, and dipalmitoylphosphatidylethanolamine (DPPE). The lipids were chosen to represent a model of a bacterial membrane. The changes in surface pressure of the model membranes, before and after the addition of Compound B, were studied by the Langmuir's monolayer method, and the compressional modulus for each monolayer was determined. In addition, the surface morphology of the lipid monolayers before and after injection of Compound B was monitored by Brewster Angle Microscopy. The results showed that Compound B penetrated all the monolayers studied. The most noticeable effects were found with the negatively charged phosphatidylglycerols and with DPPE leading to the conclusion that the electrostatic interactions between the compound and the lipid head groups and the possible formation of hydrogen bonds between the amino group of the ethanolamine and the keto groups in the structure of Compound B are of great importance. In addition, the penetration ability of the benzoquinone with all phospholipids studied was stable even at higher values of the surface pressure, i.e. thicker monolayers, due to the hydrophobic interaction, which plays also an important role for the antimicrobial activity of Compound B.

Abstract
Cell-penetrating peptides might have great potential for enhancing the therapeutic effect of drug molecules against such dangerous pathogens as Mycobacterium tuberculosis (Mtb), which causes a major health problem worldwide. A set of cationic cell-penetration peptides with various hydrophobicity were selected and synthesized as drug carrier of isoniazid (INH), a first-line antibacterial agent against tuberculosis. Molecular interactions between the peptides and their INH-conjugates with cell-membrane-forming lipid layers composed of DPPC and mycolic acid (a characteristic component of Mtb cell wall) were evaluated, using the Langmuir balance technique. Secondary structure of the INH conjugates was analyzed and compared to that of the native peptides by circular dichroism spectroscopic experiments performed in aqueous and membrane mimetic environment. A correlation was found between the conjugation induced conformational and membrane affinity changes of the INH-peptide conjugates. The degree and mode of interaction were also characterized by AFM imaging of penetrated lipid layers. In vitro biological evaluation was performed with Penetratin and Transportan conjugates. Results showed similar internalization rate into EBC-1 human squamous cell carcinoma, but markedly different subcellular localization and activity on intracellular Mtb.

Differential impact of synthetic antitumor lipid drugs on the membrane organization of phosphatidic acid and diacylglycerol monolayers. Chem Phys Lipids 2020; 229:104896.

Abstract
Anti-tumour lipids are synthetic analogues of lysophosphatidylcholine. These drugs are both cytotoxic and cytostatic, and more interestingly, exert these effects preferentially in tumour cells. While the exact mechanism of action isn't fully elucidated, these drugs appear to preferentially partition into rigid lipid domains in cell membranes. Upon insertion, the compounds alter membrane domain organization, disrupt normal signal transduction, and cause cell death. Recently, it has been reported that these drugs induce accumulation of diacylglycerol in yeast cells which in turn sensitizes cells to the drugs. Conversely, phosphatidic acid accumulation appears to protect cells against the drugs. In the current work, the aim was to compare the biophysical effects of the drugs edelfosine, miltefosine and perifosine on monolayers of dimyristoyl phosphatidic acid, dimyristoyl glycerol and an equimolar mixture, to understand how these lipids modulate the mode of action. Surface pressure - area isotherms, compression moduli and Brewster angle microscopy were used to compare drug effects on lipid packing, monolayer compressibility and lateral domain organization of these films. Results suggest that edelfosine and miltefosine have stabilizing effects on all of the monolayers, while perifosine destabilizes dimyristoyl glycerol and the equimolar mixture. Additionally, all three drugs change the morphology of the domains observed. Based on these results the stabilization of diacylgylcerol by edelfosine and miltefosine may contribute to the mode of action as diacylglycerol is a known disruptor of bilayers. Perifosine however does not stabilize diacylglycerol, and therefore cell death may occur through a more direct inhibition of specific signal transduction. These results suggest that perifosine may illicit cytotoxicity through a different mechanism compared to the other antitumor lipid drugs.

Abstract
We introduce and study a multicomponent lipid film mimicking lipid composition of the human lung surfactant. It consists of phospholipids with various lipid headgroups and tail saturation. Furthermore, it includes cholesterol and oxidized lipids. Langmuir trough and fluorescence microscopy experiments are combined with fully atomistic molecular dynamics simulations. The considered lipid mixtures form complex interfacial films with properties modulated by lateral compression. Cholesterol laterally condenses, and oxidized lipids laterally expand the films; both types of molecules increase film miscibility. Oxidized lipids also alter the lipid-water interface enhancing film hydration; this effect can be partially reversed by cholesterol. Regarding presentation of different chemical moieties toward the aqueous subphase, the zwitterionic phosphatidylcholine groups dominate at the lipid-water interface, while both the negatively charged phosphatidylglycerol and hydroxyl group of cholesterol are less exposed. The investigated synthetic lipid-only mimic of the lung surfactant may serve as a basis for further studies involving nonlipid pulmonary surfactant components.

Abstract
It is postulated that high-sensitivity C-reactive protein (hs-CRP) and tumor necrosis factor α (TNF-α) are diagnostic utilities for pleural effusion. This study was designed to explore the detection and significance of TNF-α and hs-CRP in the pleural effusion of patients with diabetes and pulmonary tuberculosis. A total of 60 patients with diabetes and pulmonary tuberculosis pleural effusion were selected as the study group, while 60 patients with pulmonary tuberculosis pleural effusion were considered as the control group. The expression of TNF-α and hs-CRP in the two groups was determined from pleural effusion by enzyme-linked immunosorbent assay (ELISA). The expression levels of TNF-α and hs-CRP in pleural effusion of the study group were significantly ( P < 0.05) higher than the control group, and the sensitivity and specificity of the combined detection were significantly ( P < 0.05) higher than those of the separate detection. The expression of TNF-α and hs-CRP in the pleural effusion of patients with diabetes and pulmonary tuberculosis increased remarkably, which plays an important role in the diagnosis and treatment helping with differential diagnosis and evaluation of severity and prognosis by related detection of changes of these indexes, especially the combined detections.

Abstract
In this work, we studied the effects of the N-alkyl group (methyl, cyclopentyl) in the piperazine ring of, respectively, rifampicin (RIF) and rifapentine (RPT) to correlate this substitution with their differential pharmacokinetic properties and overall clinical performance. Since this group is their only structural change, and given that they share the same pharmacological target, differences in their therapeutic behavior may respond to this asset, particularly in their interaction with lipid membranes across the organism. In this study, surface pressure-area isotherms, as well as spectroscopic and microscopic techniques of characterization of phospholipid monolayers at the air/water interface were used to gain insight into drug-membrane interactions. Differences in the affinity for lipid membranes for both drugs, given by the vibration frequency of characteristic chemical groups in the lipid, as well as by reflectivity and mean molecular area of the monolayer, seem to be due to the N-alkyl substituent and can contribute to provide a molecular explanation as why they pose different choices in the chemotherapy against the deadliest infectious disease, tuberculosis.

Abstract
Brewster angle microscopy (BAM) is a powerful technique that allows for real-time visualization of Langmuir monolayers. The lateral organization of these films can be investigated, including phase separation and the formation of domains, which may be of different sizes and shapes depending on the properties of the monolayer. Different molecules or small changes within a molecule such as the molecule's length or presence of a double bond can alter the monolayer's lateral organization that is usually undetected using surface pressure-area isotherms. The effect of such changes can be clearly observed using BAM in real-time, under full hydration, which is an experimental advantage in many cases. While previous BAM reviews focused more on selected compounds or compared the impact of structural variations on the lateral domain formation, this review provided a broader overview of BAM application using biological materials and systems including the visualization of amphiphilic molecules, proteins, drugs, extracts, DNA, and nanoparticles at the air-water interface.

Abstract
Mycobacterium tuberculosis (Mtb) has acquired resistance and
consequently the antibiotic therapeutic options available against this microorganism
are limited. In this scenario, the use of usnic acid (UA), a natural compound,
encapsulated into liposomes is proposed as a new approach in multidrug-resistant
tuberculosis (MDR-TB) therapy. Thus the aim of this study was to evaluate the effect
of the encapsulation of UA into liposomes, as well as its combination with
antituberculous agents such as rifampicin (RIF) and isoniazid (INH) against MDR-TB
clinical isolates. The in vitro antimycobacterial activity of UA-loaded liposomes
(UA-Lipo) against MDR-TB was assessed by the microdilution method. The in vitro
interaction of UA with antituberculous agents was carried out using checkerboard
method. Minimal inhibitory concentration values were 31.25 and 0.98 µg/mL for UA and
UA-Lipo, respectively. The results exhibited a synergistic interaction between RIF
and UA [fractional inhibitory concentration index (FICI) = 0.31] or UA-Lipo (FICI =
0.28). Regarding INH, the combination of UA or UA-Lipo revealed no marked effect
(FICI = 1.30-2.50). The UA-Lipo may be used as a dosage form to improve the
antimycobacterial activity of RIF, a first-line drug for the treatment of infections
caused by Mtb.

Nowotarska SW, Nowotarski KJ, Friedman M, Situ C. Effect of structure on the interactions between five natural antimicrobial compounds and phospholipids of bacterial cell membrane on model monolayers. Molecules 2014; 19:7497-515. [PMID: 24914896 PMCID: PMC6271777 DOI: 10.3390/molecules19067497] [Citation(s) in RCA: 60] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2014] [Revised: 05/29/2014] [Accepted: 06/03/2014] [Indexed: 11/29/2022] Open
Abstract
Monolayers composed of bacterial phospholipids were used as model membranes to study interactions of the naturally occurring phenolic compounds 2,5-dihydroxybenzaldehyde and 2-hydroxy-5-methoxybenzaldehyde, and the plant essential oil compounds carvacrol, cinnamaldehyde, and geraniol, previously found to be active against both Gram-positive and Gram-negative pathogenic microorganisms. The lipid monolayers consist of 1,2-dihexadecanoyl-sn-glycero-3-phosphoethanolamine (DPPE), 1,2-dihexa- decanoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (DPPG), and 1,1',2,2'-tetratetradecanoyl cardiolipin (cardiolipin). Surface pressure–area (π-A) and surface potential–area (Δψ-A) isotherms were measured to monitor changes in the thermodynamic and physical properties of the lipid monolayers. Results of the study indicated that the five compounds modified the three lipid monolayer structures by integrating into the monolayer, forming aggregates of antimicrobial –lipid complexes, reducing the packing effectiveness of the lipids, increasing the membrane fluidity, and altering the total dipole moment in the monolayer membrane model. The interactions of the five antimicrobial compounds with bacterial phospholipids depended on both the structure of the antimicrobials and the composition of the monolayers. The observed experimental results provide insight into the mechanism of the molecular interactions between naturally-occurring antimicrobial compounds and phospholipids of the bacterial cell membrane that govern activities.

Abstract
Exogenous pulmonary surfactant is a potential delivery system for topical medications via the conducting airways. Due to the sensitivity to inactivation of surfactant, mutual interaction with the shipped drug should be evaluated. Little is known about the interactions between surfactant and antimicrobial drugs. The aim of the present study was to evaluate whether biophysical properties of animal-derived surfactants are modified by the bactericidal antibiotic rifampicin. An intracellular activity and a broad antimicrobiotic spectrum toward Gram-negative and Gram-positive bacteria make rifampicin an interesting substance against pulmonary infections. Curosurf® (porcine surfactant from minced lungs) and Survanta® (bovine surfactant extract) were diluted to 2.5-5.0 mg/ml of phospholipids in 0.9 % NaCl and rifampicin (RIF) was added at 1, 5, and 10 % (w/w). Minimum (γ(min)) and maximum (γ(max)) surface tension of a cyclically compressed bubble in the mixture was assessed with a pulsating bubble surfactometer. After 5 min, γ(min) of Survanta at a concentration of 3 mg/ml was significantly increased after addition of 5 and 10 % RIF (both p < 0.001). At 1 % RIF, the γ(min) of Survanta was ≈10 mN/m and this value was not significantly different to that of Survanta alone. The γ(min) of Curosurf at 3 mg/ml was increased with 10 % RIF (p < 0.001), but not with 1 and 5 %. At 5 mg/ml Survanta was inhibited by 10 % RIF (p < 0.05), while γ(min) of Curosurf was low (<5 mN/m) in all mixtures. In conclusion, Curosurf and Survanta interfere with RIF in a concentration-dependent manner. At the appropriate phospholipid concentration, especially porcine-derived surfactant is able to retain good surface activity when mixed with antibiotics.
