Abstract
This study explored the mechanism of interaction between chlorogenic acid (CA) and protein fibrils (PF) as well as the effects of varying the CA/PF concentration ratio on antibacterial activity. Analysis of various parameters, such as ζ-potential, thioflavin T fluorescence intensity, surface hydrophobicity, and free sulfhydryl groups, revealed that the interaction between PF and CA altered the structure of PF. Fluorescence analysis revealed that hydrogen bonding and hydrophobic interactions were the primary interaction forces causing conformational rearrangement, resulting in a shorter, more flexible, and thicker fibril structure, as observed through transmission electron microscopy. Fourier-transform infrared spectroscopy, small-angle X-ray scattering, and X-ray diffraction analyses revealed that the characteristic fibril structure was destroyed when the CA/PF ratio exceeded 0.05. Notably, the CA-PF complexes inhibited the growth of Escherichia coli and Staphylococcus aureus and also exhibited antioxidant activity. Overall, this study expands the application prospects of CA and PF in the food industry.

Vignesh V, Kavalappa YP, Ponesakki G, Madhan B, Shanmugam G. Lutein, a carotenoid found in numerous plants and the human eye, demonstrates the capacity to bundle collagen fibrils. Int J Biol Macromol 2024; 274:133389. [PMID: 38925203 DOI: 10.1016/j.ijbiomac.2024.133389] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2023] [Revised: 05/29/2024] [Accepted: 06/21/2024] [Indexed: 06/28/2024]
Abstract
Collagen fibrils serve as the building blocks of the extracellular matrix, providing a resilient and structural framework for tissues. However, the bundling of collagen fibrils is of paramount importance in maintaining the structural integrity and functionality of various tissues in the human body. In this scenario, there is limited exploration of molecules that promote the bundling of collagen fibrils. Investigating the interactions of well-known carotenoids, commonly associated with ocular health, particularly in the retina, with collagen presents a novel and significant area of study. Here, we studied the influence of lutein, a well-known carotenoid present in many plant tissues and has several biological properties, on the structure, thermal stability, self-assembly, and fibrillation of collagen. Fibrillation kinetics and electron microscopic analyses indicated that lutein did not interfere with fibrillation process of collagen, whereas it enhances the lateral fusion of collagen fibrils leading to the formation of compact bundles of thick fibrils under physiological conditions. The hydrophobic and hydrogen bonding interactions between lutein and collagen fibrils are most likely the cause of the bundling of the fibrils. This study establishes the first investigation of collagen-carotenoid interactions, showcasing the unique property of lutein in bundling collagen fibrils, which may find potential application in tissue engineering.

Fabrication of atelocollagen-coated bioabsorbable suture and the evaluation of its regenerative efficacy in Achilles tendon healing using a rat experimental model. Int J Biol Macromol 2024; 271:132564. [PMID: 38782324 DOI: 10.1016/j.ijbiomac.2024.132564] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2024] [Revised: 05/18/2024] [Accepted: 05/20/2024] [Indexed: 05/25/2024]
Abstract
Recently, the incidence of Achilles tendon ruptures (ATRs) has become more common, and repair surgery using a bioabsorbable suture is generally preferred, particularly in the case of healthy patients. Sutures composed of poly(lactic-co-glycolic acid) (PLGA) are commonly used in ATR surgeries. Nevertheless, owing to the inherent limitations of PLGA, novel bioabsorbable sutures that can accelerate Achilles tendon healing are sought. Recently, several studies have demonstrated the beneficial effects of atelocollagen on tendon healing. In this study, poly(3,4-dihydroxy-L-phenylalanine) (pDOPA), a hydrophilic biomimetic material, was used to modify the hydrophobic surface of a PLGA suture (Vicryl, VC) for the stable coating of atelocollagen on its surface. The main objective was to fabricate an atelocollagen-coated VC suture and evaluate its performance in the healing of Achilles tendon using a rat model of open repair for ATR. Structural analyses of the surface-modified suture indicated that the collagen was successfully coated on the VC/pDOPA suture. Postoperative in vivo biomechanical analysis, histological evaluation, ultrastructural/morphological analyses, and western blotting confirmed that the tendons in the VC/pDOPA/Col group exhibit superior healing than those in the VC and VC/pDOPA groups after 1 and 6 weeks following the surgery. The this study suggests that atelocollagen-coated PLGA/pDOPA sutures are preferable for future medical applications, especially in the repair of ATR.

Abstract
Tuning the self-assembly of collagen has broad applications in the biomedical field owing to their desired biological performance as collagenous materials with tunable functionalities can further determine cellular responses. In this work, an attempt has been made to tune the self-assembly of collagen using ionic liquids, viz., imidazolium chloride (IC) and choline dihydrogen phosphate (CDHP) at its physiological pH, followed by probing assembled systems using various characterization methods. Turbidity measurements of fibrillar networks were performed to ascertain the rate of fibril formation in addition of imidazolium chloride and choline dihydrogen phosphate to collagen at physiological pH. Morphological changes were examined using Scanning Electron Microscope (SEM), binding affinities were measured by Microscale Thermophoresis (MST), in addition to, changes in the shear viscosity, mechanical strength of collagen fibrils when interacted with imidazolium and choline based ILs were carried out using rotational rheometer and Quartz Crystal Microbalance (QCM) measurements. Experimental result depicts that CDHP imparts better crosslinking as well as mechanical strength compare to IC, which is already known for destabilizing the triple helix structure is inhibiting the fibril formation. This self-assembled, ionic-liquid treated collagen-fibrillar system would accelerate various force modulated fibrillar network study, for mimicking the ECM and tissue engineering application.

Abstract
Cultured meat has the potential to fulfill the meat demand for the growing human population, but cultured meat development will be required to simplify the production process and produce naturally cultured meat, such as no longer stripping off scaffolders and adding artificial dyes. In this study, proanthocyanidins (PC) and dialdehyde chitosan (DAC) were employed as dual crosslinkers with collagen to prepare a hybrid 3D edible scaffold for the production of high-quality cell-cultured meat. The results revealed that the scaffold was biocompatible and could offer robust mechanical support and adhesion sites for bovine myoblasts, enabling long-term cell culture. Meanwhile, the Col-PC-DAC scaffold promoted the myogenic differentiation of bovine myoblasts and extracellular matrix protein secretion, further affecting the texture of cultured meat. After cooking the cultured meat and beef, it was shown that the cultured meat had some similarities to beef in color and flavor. Importantly, our findings demonstrate that cultured meat can acquire a color remarkably similar to that of conventional beef without the need for artificial dyeing. This breakthrough not only simplifies the production process but also ensures a more natural and appealing appearance of cultured meat. In conclusion, the proanthocyanidins-dialdehyde chitosan-collagen hybrid 3D edible scaffolds provide a new option for producing cultured meat that satisfies consumer expectations.

Abstract
MIF/CD74 signaling pathway and autophagy may be closely related to liver fibrosis. Vanillic acid (VA) is likely to have an anti-liver fibrosis effect, although related studies have not been reported. The aim of this study was to verify the role of hepatic stellate cells (HSCs) autophagy and the MIF/CD74 signaling pathway in the pathogenesis of liver fibrosis, and to investigate the effect of VA on liver fibrosis through in vivo and in vitro experiments. Our results showed that VA significantly attenuated CCl4-induced liver fibrosis. The alleviation of liver fibrosis with VA treatment was associated with a reduction of MIF, CD74, α-SMA, LC3B and Collagen 1. In addition, VA, MIF inhibitor (ISO-1) and autophagy inhibitor (3-MA) markedly inhibited the proliferation and migration of HSCs. This study indicates that VA could protect against HSCs activation, proliferation and migration by inhibiting the autophagy in HSCs via the MIF/CD74 signaling pathway so that alleviates liver fibrosis.

Abstract
The rapeseed (Brassica napus L.) are the important oil bearing material worldwide, which contain wide variety of bioactive components with polyphenolic compounds considered the most typical. The rapeseed polyphenols encompass different structural variants, and have been considered to have many bioactive functions, which are beneficial for the human health. Whereas, the rapeseed oil processing technologies affect their content and the biofunctional activities. The present review of the literature highlighted the major types of the rapeseed polyphenols, and summarized their biofunctional roles. The influences of rapeseed oil processing technologies on these polyphenols were also elucidated. Furthermore, the directions of the future studies for producing nutritional rapeseed oils preserved higher level of polyphenols were prospected. The rapeseed polyphenols are divided into the phenolic acids and polyphenolic tannins, both of which contained different subtypes. They are reported to have multiple biofunctional roles, thus showing outstanding health improvement effects. The rapeseed oil processing technologies have significant effects on both of the polyphenol content and activity. Some novel processing technologies, such as aqueous enzymatic extraction (AEE), subcritical or supercritical extraction showed advantages for producing rapeseed oil with higher level of polyphenols. The oil refining process involved heat or strong acid and alkali conditions affected their stability and activity, leading to the loss of polyphenols of the final products. Future efforts are encouraged to provide more clinic evidence for the practical applications of the rapeseed polyphenols, as well as optimizing the processing technologies for the green manufacturing of rapeseed oils.

Abstract
This study investigated the effects of syringic acid (SA) on renal, cardiac, hepatic, and neuronal diabetic complications in streptozotocin-induced neonatal (nSTZ) diabetic rats. STZ (110 mg/kg i.p) was injected into Wistar rat neonates as a split dose (second and third postnatal day). Diabetes mellitus was diagnosed in adults by measuring fasting blood glucose levels, urine volume, and food and water intake. The treatment of SA (25 mg/kg, 50 mg/kg p.o) was given from the 8th to 18th postnatal week. To assess the development of diabetic complications and the effect of therapy, biochemical indicators in serum and behavioural parameters were recorded at specific intervals during the study period. SA (25 mg/kg, 50 mg/kg p.o) treatment reduced hyperglycaemia, polydipsia, polyphagia, polyuria, relative organ weight, cardiac hypertrophic indices, inflammatory markers, cell injury markers, glycated haemoglobin, histopathological score, and oxidative stress, and increased Na/K ATPase activity. These findings suggest that SA might significantly alleviate diabetic complications and/or renal, neuronal, cardiac, and hepatic damage in nSTZ diabetic rats.

Abstract
Pumpkin is a well-known multifunctional ingredient in the diet, full of nutrients, and has opened new vistas for scientists during the past years. The fruit of pumpkin including the flesh, seed, and peel are a rich source of primary and secondary metabolites, including proteins, carbohydrates, monounsaturated fatty acids, polyunsaturated fatty acids, carotenoids, tocopherols, tryptophan, delta-7-sterols, and many other phytochemicals. This climber is traditionally used in many countries, such as Austria, Hungary, Mexico, Slovenia, China, Spain, and several Asian and African countries as a functional food and provides health promising properties. Other benefits of pumpkin, such as improving spermatogenesis, wound healing, antimicrobial, anti-inflammatory, antioxidative, anti-ulcerative properties, and treatment of benign prostatic hyperplasia have also been confirmed by researchers. For better drug delivery, nanoemulsions and niosomes made from pumpkin seeds have also been reported as a health promising tool, but further research is still required in this field. This review mainly focuses on compiling and summarizing the most relevant literature to highlight the nutritional value, phytochemical potential, and therapeutic benefits of pumpkin.

Abstract
β-Cyclodextrin (β-CD), a macrocyclic oligosaccharide cavitand, is a well-known candidate for drug delivery and formulation. In this study, we extended the application of β-CD using a β-cyclodextrin sulfate (β-CDS) as a possible therapeutic for fibrotic diseases caused by excess deposition of collagen fibrils. We have strategically chosen β-CDS, which mimics the natural existence of dermatan sulfate in the extracellular matrix, for limiting collagen fibrillation. The hydrophobic nature of the inner core β-CDS is expected to form an inclusion complex with hydrophobic side chain amino acids with the simultaneous action of forming an ionic bond through a negative charge on sulfate group with positively charged amino acids side chain in collagen. Various results suggested that such dual action not only limited the collagen fibrillation but also reduced the fibril size formed in the presence of β-CDS. The contemporary results thus indicate that β-CDS can be explored as a therapeutic molecule in fibrotic diseases.

Abstract
Small molecules ranging from organic to inorganic systems have been reported as stabilizing agents for collagen. Various transition metal complexes have been utilized as tanning agent. However, as per the environmental norms issued by various regulatory agencies, the presence of certain metals such as Cr, Fe, Al, Zr and Ti in leather has been restricted to minimal amount (50 ppm), an unsurmountable task. To overcome the above issue and find an alternative tanning system, here in this study, we have reported the interaction of two water-soluble zinc-based metal-organic frameworks (MOFs), i.e., ZnPV (1) and ZnPA (2), with collagen using various spectroscopic techniques. Fibrillation kinetics studies showed that a significant delay in fibril formation with Zn-MOFs treated collagen was observed compared to the collagen untreated/ treated with individual ligands and metal salt. Circular dichroism studies show that at a low weight ratio (1:0.2 and 1:1::Collagen: MOF), no perturbation in the triple helical structure was observed, while at higher weight ratio (1:4), denaturation of collagen occurs. FT-IR studies showed that no perturbation was observed in the amide backbone in MOF-treated collagen. Differential scanning calorimetric data revealed that both Zn-MOFs increased the thermal denaturation temperature by 22 ± 2 °C compared to the collagen treated with individual entities. The viscosity of collagen rises with the increase in the concentration of Zn-MOFs. To the best of our knowledge, this is the first report on the use of the metal-organic framework as a stabilizing agent for collagen structure and might help in exploring the MOFs as potential tanning agents.

Abstract
Naturally derived ingredients are becoming more prevalent in therapeutic drug formulations due to consumers' concerns about chemical side effects. In the context of wound care, despite the impressive progress in therapeutic product development, drugs dispensed to treat impaired healing challenged by biofilms; excessive inflammation and oxidation are not yet really effective. Thus, the hunts for improved drug formulations preferably using natural ingredients that are cost-effective in accelerating the wound-healing process are of constant demand. The grape seed extract is extensively studied and is reported to be rich in phenolic compounds, unsaturated fatty acids and vitamins which exhibit numerous therapeutic benefits owing to their anti-inflammatory, anti-microbial, and anti-oxidative properties that support its potential use in the development of wound-healing products. We conducted a literature study using Scopus, PubMed, and Google Scholar including the keywords "grape seed extract" and "wound healing". We also scanned all the references cited by the retrieved articles. Accordingly, this review is aimed to (i) explore the various phytochemical constituents found in grape seed extracts along with their mechanism of action that instigate wound healing, (ii) to highlight the latest pre-clinical and clinical assessments of grape seed extract in wound models, and (iii) to encourage innovation scientists in the field to address current limitations and to effectively develop grape seed extract-based wound care product formulations for commercialization.

Abstract
Protein-phenolic compound interactions are commonly investigated with inappropriate linear equations for the analysis of binding strength and stoichiometry. This work utilises more appropriate protocols for the investigation of molecular interactions between vanillic acid and β-lactoglobulin at pH 2.4, where the protein predominately exists as a monomer. Non-linear binding and Job plot analysis were conducted on fluorescence data to effectively determine the interaction's dissociation constant (KD, 2.93 × 10-5 M) and stoichiometry (1:1). Furthermore, spectroscopic techniques revealed statistically significant alterations to the conformational characteristics of β-lactoglobulin upon complexation. Molecular dynamics (MD) simulations support a 1:1 interaction stoichiometry and reveal that the stabilisation of vanillic acid was dynamic in nature but mainly supported by four π-alkyl interactions and one hydrogen bond, located within the β-barrel of the monomer. Water molecules, which are generally not accounted for in MD simulation analysis, were shown to be an important factor in the ligand stabilization via bridging interactions.

Abstract
As a heparin analogue, sulfonated chitosan (SCS) has been confirmed to have similar structure and properties to heparin which is shown to be a linker molecule having specific binding sites with collagen fibrils. In this study, the effects of a varying concentration of SCS on the self-assembly process of type I collagen were investigated. The study on intermolecular interaction between collagen and SCS was carried out via using ultraviolet-visible (UV-vis) spectrophotometry and circular dichroism (CD) spectroscopy. The addition of SCS did not disrupt the triple helix conformation of collagen. However, the decreased value of Rpn showed that the SCS, to some extent, influenced the percentage of triple helix conformation. The turbidity measurements revealed that the self-assembly rate was increased in the presence of a low concentration of SCS whereas decreased with further increasing the SCS concentration. The observation of microstructure via scanning electron microscopy (SEM) and atomic force microscopy (AFM) exhibited the characteristic D-periodicity, indicating that the presence of SCS did not disrupt the self-assembly nature of collagen. Moreover, the addition of SCS facilitated the lateral aggregation of fibrils, leading to the formation of larger fibrils. The rheological analysis showed that the gelation time of collagen was prolonged with increasing the concentration of SCS, in support of a longer lag-phase duration detected in turbidimetric measurements. We expect that valuable data would be provided in this study for further developing of ECM analogues, and propitious performances could be endowed to these biomimetic materials after SCS incorporation.

Abstract
Highly efficient and regioselective synthesis of pharmacologically interesting aromatic esters of arbutin catalyzed by immobilized lipase from Penicillium expansum in co-solvent systems was successfully carried out. As compared to tetrahydrofuran solvent, the initial rate and substrate conversion of arbutin vanilylation were markedly enhanced in tetrahydrofuran-isopropyl ether (20%, v/v). Moreover, the effects of three reaction parameters (enzyme amount, temperature and substrate molar ratio of vinyl vanillic acid to arbutin) on 6′-O-vanilloyl-arbutin synthesis were scrutinized and the key process parameters were optimized using response surface methodology (RSM). The experimental data were fitted well to a second order polynomial model by using multiple regression analysis. The best combination of variables was 50°C, 93 U/mL and 11 for the reaction temperature, the enzyme amount and mole ratio of arbutin to vinyl vanilic acid, respectively, and which the reaction rate, substrate conversion and regioselectivity were as high as 8.2 mM/h, 93 and 99%. It was worth noting that a variety of aromatic esters of arbutin were obtained with much higher conversion (93–99%) at these optimal conditions.

Abstract
An ultra-performance liquid chromatography-electrospray ionization-mass spectrometry targeted metabolomics strategy was applied to analyze protocatechuate, syringin, eleutheroside E, isofraxidin, hyperoside, kaempferol, and oleanolic acid, the active compounds in 3-year-old, 5-year-old, and 9-year-old Acanthopanax senticosus. Then, targeted metabolomics was conducted with 3 growth year plants to identify 19 phenolic metabolites related to the above-mentioned active compounds, including 9 C6C3C6-type, 6 C6C3-type, and 4 C6C1-type. Multivariate statistical analysis was applied to the bioactive metabolite data, and targeted metabolic profiling was used for marker compound classification and characterization. The results showed that 7 active compounds in the roots and stems in the 3 growth year plants differed. The principal component “Q” values showed that the total contents of 7 active compounds in 5-year-old roots and stems were higher than in other growth years. Results of targeted metabolomics profiling of 19 phenolic metabolites showed that the C6C1-type compounds accumulated in 9-year-old plants, the C6C3-type in 3-year-old plants, and the C6C3C6-type in 5-year-old plants. The stems had the greatest accumulations of the phenolic metabolites. C6C1 and C6C3-type metabolites are the most abundant in both roots and stems. In conclusion, the active compounds and pharmacological effects of A. senticosus in different growth years are different. The best harvest age for A. senticosus roots and stems was 5 years. The accumulation of 19 phenolic metabolites in different growth years also showed significant differences.

Abstract
Cyanidin-3-glucoside (C3G) is a well-known natural anthocyanin and possesses antioxidant and anti-inflammatory properties. The catabolism of C3G in the gastrointestinal tract could produce bioactive phenolic metabolites, such as protocatechuic acid, phloroglucinaldehyde, vanillic acid, and ferulic acid, which enhance C3G bioavailability and contribute to both mucosal barrier and microbiota. To get an overview of the function and mechanisms of C3G and its phenolic metabolites, we review the accumulated data of the absorption and catabolism of C3G in the gastrointestine, and attempt to give crosstalk between the phenolic metabolites, gut microbiota, and mucosal innate immune signaling pathways.

Abstract
Collagens were extracted from grass carp skin (GCC), grass carp scales (GSC), and crucian carp skin (CCC) using an acid-enzyme combination method, and their characteristics and self-assembly properties were analyzed. Electrophoretic patterns characterized all three as type I collagens. An ultraviolet analysis identified the optimal wavelengths for collagen detection, while a Fourier transform infrared spectroscopy analysis confirmed the triple-helical structure of the collagens. The GCC, GSC, and CCC had denaturation temperatures of 39.75, 34.49, and 39.05 °C, respectively. All three were shown to self-assemble into fibrils at 30 °C in the presence of NaCl, but the fibril formation rate of CCC (40%) was slightly higher than those of GCC (28%) and GSC (27%). The GSC were shown to form a more strongly intertwined fibril network with a characteristic D-periodicity. The fish collagens extracted in this study have potential applications in the development of functionalized materials.

Abstract
Type I collagen is a vital structural component of the extracellular matrix providing the connective tissues with biomechanical support. One of the interesting properties of collagen is to self-associate into fibrils. The present work aims to direct the self-assembly of collagen through different molecular forces, which are tuned on the addition of thymoquinone a well-known phytochemical. A change in relative viscosity and stress of collagen-thymoquinone blends influenced the interfibrillar aggregates around its hydration shell. Further, secondary structural integrity was studied via cotton curve effect, and vibrational frequency shifts showed a characteristic interaction of thymoquinone at the N-terminal residues of the triple helix. Finally, the spontaneous self-association of fibrils was tracked by calculating the rate of fibril growth kinetics, which potentially decreased with increase in thymoquinone concentration. The fibrils were eventually visualized under the high resolution-scanning microscope showing morphological variations. Therefore, such a protein-phytochemical interaction may tend to play with the hydration network of collagen and covalently interact with its imino acid residues. It may be speculated that such an inhibitory process portrayed by thymoquinone may have a fortune in the targeted and sustainable delivery to the site of action for certain diseases, which includes collagen accumulation. Moreover, its directed assembly could be utilized for designing templates as in manipulating the collagen as a nanoporous membrane to make nanofibers and further tuned by small molecules for nanoparticle synthesis application.

Abstract
Lignocellulosic biomass is a promising alternative for the replacement of limited fossil resources to produce various chemical compounds, such as 5-hydroxymethylfurfural, furfural, vanillin, vanillic acid, ferulic acid, syringaldehyde, and 4-aminobenzoic acid. However, the complex biomass structure is a limitation to making effective use of this naturally found feedstock. This research presents a data set of different compounds obtained directly from forest residues, with special emphasis on achieving effective utilization of the biomass. The extraction method and the catalyst are considered as the two main factors in this valorization process.

Alternatives
to petroleum-based plastics are of great significance
not only from the point of view of their scientific and practical
impact but to reduce the environmental footprint. Inspired by the
composition and structure of wood’s cell walls, we used phenolic
acids to endow cellulosic fibers with new properties. The fiber dissolution
and homogeneous modification were performed with a recyclable ionic
liquid (IL) (tetrabutylammonium acetate ([N4444][OAc]):dimethyl
sulfoxide) to attain different levels of reaction activity for three
phenolic acids (p-hydroxybenzoic acid, vanillic acid,
and syringic acid). The successful autocatalytic Fischer esterification
reaction was thoroughly investigated by Fourier transform infrared
spectroscopy, X-ray photoelectron spectroscopy, elemental analysis,
and nuclear magnetic resonance spectroscopy (13C CP-MAS,
diffusion-edited 1H NMR and multiplicity-edited heteronuclear
single quantum coherence). Control of the properties of cellulose
in the dispersed state, welding, and IL plasticization were achieved
during casting and recrystallization to the cellulose II crystalline
allomorph. Films of cellulose carrying grafted acids were characterized
with respect to properties relevant to packaging materials. Most notably,
despite the low degree of esterification (DS < 0.25), the films
displayed a remarkable strength (3.5 GPa), flexibility (strains up
to 35%), optical transparency (>90%), and water resistance (WCA
∼
90°). Moreover, the measured water vapor barrier was found to
be similar to that of poly(lactic acid) composite films. Overall,
the results contribute to the development of the next-generation green,
renewable, and biodegradable films for packaging applications.

Abstract
Type I collagen is a fibrous protein, which is highly biocompatible and biodegradable and exhibits low immunogenicity with its unique feature of undergoing a spontaneous self-assembly process. However, the excessive accumulation of collagen may lead to a condition known as fibrosis in vertebrates. Recently, saturated fatty acids have gained much attention as biomedical and therapeutic agents. Therefore, drawing inspiration from the biological and structural tunability of these fatty acids, this work aims to inhibit the self-assembly of type I collagen using (±)-α-lipoic acid (ALA). Reconstituted collagen and its blends with (±)-ALA under physiological conditions were subjected to fibril growth kinetics measurements, which exhibited the decrease in the rate of fibrillogenesis ( t1/2) with an increase in the concentration of ALA. Variations in the viscoelasticity of collagen and ALA blend with respect to rate and frequency showed significant changes. Further, the frequency shifts of different functional groups via FT-IR (ATR) and the morphological changes associated with fibril inhibition were visualized using a cryoscanning electron microscope. Molecular dynamics simulation of the collagen-like peptide with the (±)-ALA molecule at different molar ratios proved that (±)-ALA had a strong potential to bind at various sites of collagen mediated by conventional secondary or noncovalent forces. Thus, the protein-small molecule interaction dominates the forces prevailing between protein-protein binding, leading to the inhibition of the self-assembly process. Such inhibitory effects by a fatty acid may unfold newer avenues for development of targeted and sustainable drug delivery systems for fibrotic diseases.

[PMID: 30474283 DOI: 10.1002/ddr.21487] [Citation(s) in RCA: 32] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2018] [Revised: 10/05/2018] [Accepted: 10/09/2018] [Indexed: 01/08/2023]
Abstract
Asthma is termed as the induction of chronic inflammation in the airway lumen of lungs due to accumulation of inflammatory cells which affects normal breathing process. Prolonged accumulation of inflammatory cells leads to oxidative stress and suppression of antioxidant activities. Therefore, in our present investigation, a potential phenolic compound, Syringic acid was tested for the suppression of inflammatory markers toward an antiasthmatic activity in ovalbumin (OVA)-induced asthmatic mice model. As a result, the Syringic acid treatment was found to suppress the inflammatory cells; eosinophil, neutrophil, macrophage, lymphocyte, and other inflammatory markers including IL-4, IL-5, IL-13, and TNF-α in the BALF of OVA-induced asthmatic mice. Similarly, IgE levels were significantly reduced in the blood serum of Syringic acid treated mice groups. In this context, the IFN-γ levels were found enhanced in the BALF of Syringic acid treated asthmatic mice groups, expressing an anti-inflammatory response. Enzymatic and nonenzymatic antioxidants such as SOD, CAT, and GSH levels were found high in the Syringic acid treatment than the asthmatic control group, which depicts the antioxidant response of Syringic acid on asthmatic groups. Intriguingly, the ROS, NO2 , NO3 , and MDA levels were inhibited in the BALF of Syringic acid treated mice groups. The airway hyper-reactivity (AHR) was comparatively normal in the Syringic acid treatment as it was severe in the case of asthmatic control group. Consequently, the effect of Syringic acid is prominent in the treatment of asthma by controlling the accumulation of inflammatory cells, other inflammatory markers along with enhancement of antioxidant markers, suppression of ROS and controlling airway hyperreactivity. Hence, Syringic acid may be recommended for clinical trials in the treatment of asthma.
