Abstract
We report the synthesis, molecular docking and anticancer properties of the novel compound (E)-1-methyl-9-(3-methylbenzylidene)-6,7,8,9-tetrahydropyrazolo[3,4-d]pyrido[1,2-a]pyrimidin-4(1H)-one (PP562). PP562 was screened against sixteen human cancer cell lines and exhibited excellent antiproliferative activity with IC50 values ranging from 0.016 to 5.667 μM. Experiments were carried out using the target PP562 at a single dose of 1.0 μM against a kinase panel comprising 100 different enzymes. A plausible binding mechanism for PP562 inhibition of DDR2 was determined using molecular dynamic analysis. The effect of PP562 on cell proliferation was also examined in cancer cell models with both high and low expression of the DDR2 gene; PP562 inhibition of high-expressing cells was more prominent than that for low expressing cells. PP562 also exhibits excellent anticancer potency toward the HGC-27 gastric cancer cell line. In addition, PP562 inhibits colony formation, cell migration, and adhesion, induces cell cycle arrest at the G2/M phase, and affects ROS generation and cell apoptosis. After DDR2 gene knockdown, the antitumor effects of PP562 on tumor cells were significantly impaired. These results suggested that PP562 might exert its inhibitory effect on HCG-27 proliferation through the DDR2 target.

Abstract
Polysaccharides play significant role in the management of different cancer types including gastric cancer. Here, we report the effect of spirulina polysaccharide (Sp) on galectin-3 modulatory activity in gastric cancer cells (AGS). The isolated Sp possessed an average molecular weight of 1457 kDa and galactose (42%) as a major sugar consisting of (β1-4d) units with a galactoarabinorhamnoglycan backbone. The Sp inhibited the proliferation of AGS cells by 48% without affecting normal NIH/3T3 cells as compared to doxorubicin, a known anticancer drug. Also, Sp exhibited significant (p < 0.05) galectin-3 mediated hemeagglutination inhibition with MIC of 9.37 μg/mL compared to galactose (6.25 μg/mL), a sugar specific to galectin-3. Galactose showed the highest molecular interaction with galectin-3 in the in silico study. In addition, Sp exhibited the cytoprotection in RBCs, buccal cells, and DNA exposed to oxidants. These findings suggest that Sp offers a promising therapeutic tool in the management of gastric cancer.

Pectins from various sources inhibit galectin-3-related cardiac fibrosis. Curr Res Transl Med 2021; 70:103321.

Abstract
PURPOSE OF THE STUDY A major challenge in cardiology remains in finding a therapy for cardiac fibrosis. Inhibition of galectin-3 with pectins attenuates fibrosis in animal models of heart failure. The purpose of this study is to identify pectins with the strongest galectin-3 inhibitory capacity. We evaluated the in vitro inhibitory capacity, identified potent pectins, and tested if this potency could be validated in a mouse model of myocardial fibrosis. METHODS Various pectin fractions were screened in vitro. Modified rhubarb pectin (EMRP) was identified as the most potent inhibitor of galectin-3 and compared to the well-known modified citrus pectin (MCP). Our findings were validated in a mouse model of myocardial fibrosis, which was induced by angiotensin II (Ang II) infusion. RESULTS Ang II infusion was associated with a 4-5-fold increase in fibrosis signal in the tissue of the left ventricle, compared to the control group (0•22±0•10 to 1•08±0•53%; P < 0•001). After treatment with rhubarb pectin, fibrosis was reduced by 57% vs. Ang II alone while this reduction was 30% with the well-known MCP (P = NS, P < 0•05). Treatment was associated with a reduced cardiac inflammatory response and preserved cardiac function. CONCLUSION The galectin-3 inhibitor natural rhubarb pectin has a superior inhibitory capacity over established pectins, substantially attenuates cardiac fibrosis, and preserves cardiac function in vivo. Bioactive pectins are natural sources of galectin-3 inhibitors and may be helpful in the prevention of heart failure or other diseases characterized by fibrosis.

Abstract
Galectin-3 is a member of a family of β-galactoside-binding proteins. A substantial body of literature reports that galectin-3 plays important roles in cancer, inflammation, and fibrosis. Small-molecule galectin-3 inhibitors, which are generally lactose or galactose-based derivatives, have the potential to be valuable disease-modifying agents. In our efforts to identify novel galectin-3 disaccharide mimics to improve drug-like properties, we found that one of the monosaccharide subunits can be replaced with a suitably functionalized tetrahydropyran ring. Optimization of the structure-activity relationships around the tetrahydropyran-based scaffold led to the discovery of potent galectin-3 inhibitors. Compounds 36, 40, and 45 were selected for further in vivo evaluation. The synthesis, structure-activity relationships, and in vivo evaluation of novel tetrahydropyran-based galectin-3 inhibitors are described.

Abstract
Fruits are a prime source of nutrients, bioactive compounds, and dietary fibers. Some products available on the Brazilian market use fruit by-products and claim to have useful effects on human health due to their dietary fiber content. The study aimed to extract and purify the total (28-47 w/w yield) and soluble dietary fiber (4-7 w/w yield) from jaboticaba, papaya, and plum commercial flours sold in Brazil and to study the in vitro biological effects of the fractions. The purified water-soluble fractions consisted mainly of pectin-derived oligosaccharides (5-15 KDa molecular weight) with a negligible content of polyphenols, protein, ashes, and starch. Jaboticaba sample was 95% galacturonic acid while plum and papaya samples were 40% galacturonic acid and 40% galactose (mol%), approximately. The samples were tested for recombinant human galectin-3 inhibition and changes in the cell viability of human colorectal cancer cells. Only the jaboticaba sample inhibited galectin-3 and decreased HCT116 cell viability after 48 h of treatment (p ≤ 0.01) while the plum sample decreased the cell viability after 24 h treatment (p ≤ 0.05). The results obtained in this study demonstrate the relationship between the structure of the soluble fibers extracted from jaboticaba flour and the possible beneficial effects of their consumption.

Abstract
Modified citrus pectin (MCP) has a low-molecular-weight degree of esterification to allow absorption from the small intestinal epithelium into the circulation. MCP produces pleiotropic effects, including but not limited to its antagonism of galectin-3, which have shown benefit in preclinical and clinical models. Regarding cancer, MCP modulates several rate-limiting steps of the metastatic cascade. MCP can also affect cancer cell resistance to chemotherapy. Regarding fibrotic diseases, MCP modulates many of the steps involved in the pathogenesis of aortic stenosis. MCP also reduces fibrosis to the kidney, liver, and adipose tissue. Other benefits of MCP include detoxification and improved immune function. This review summarizes the pleiotropic effects of MCP.

Abstract
Galectin-3 and galectin-3 binding proteins (G3BP) are implicated as key players in metastasis. In the current study, we evaluated the effect of pectic polysaccharides on galectin-3 and G3BP mediated metastasis in vitro (cells) and in vivo (tissues). In vitro study (double immunostaining) confirms the presence of galectin-3 on the cell surface and G3BP in the interlinking region of the cells confirming the role of G3BP in bridging galectin-3 molecules. Dietary carrot (Daucus carota) pectic polysaccharide (CRPP) blocked the expression of galectin-3 and G3BP more effectively (80%), whereas the expressions were reduced to 60% upon treatment with swallow root (Decalepis hamiltonii) pectic polysaccharide (SRPP), β‑carotene and deferoxamine (antiproliferative drug). Ginger (Gingiber officinale) pectic polysaccharide (GRPP) showed only 20% reduction. CRPP reduced 80% of tumor incidence followed by cyclophosphamide - a chemotherapeutic drug (77%), SRPP (67%) and GRPP (45%). Further 3-5 folds reduction in galectin-3/G3BP expression followed by infiltration of macrophages into the deeper layer of the skin by CRPP and SRPP suggested the anticancer property via immunomodulation. Surface Plasmon Resonance (SPR) studies confirm galectin-3 and G3BP interaction, which are disrupted during the treatment with dietary pectic polysaccharides (DPP) (Supplementary Scheme-1). Overall data demonstrate the role of DPPs as potential anticancer alternatives.

Abstract
Galactans are linear polysaccharides of β(1→4)-linked galactose residues. Although they can antagonize galectin function, the nature of their binding to galectins needs to be better defined to develop them as drugs. Here, we investigated interactions between galectin-3 (Gal-3) and a series of galactans ranging in weight average molecular weight from 670 to 7550 Da. 15N-1H HSQC NMR studies with 15N-labeled Gal-3 carbohydrate recognition domain (CRD) indicate that each of these galactans interacts primarily with residues in β-strands 4, 5 and 6 on the canonical, β-galactoside sugar binding S-face. Although these galactans also bind to full length Gal-3 (CRD plus N-terminal tail) to the same extent, it appears that binding to the S-face attenuates interactions between the CRD F-face and N-terminal tail, making interpretation of site-specific binding unclear. Following assignment of galactan 13C and 1H resonances using HSQC, HMBC and TOCSY experiments, we used 13C-1H HSQC data to demonstrate that the Gal-3 CRD binds to the terminal, non-reducing end of these galactans, regardless of their size, but with binding affinity increasing as the galactan chain length increases. Overall, our findings increase understanding as to how galactans interact with Gal-3 at the non-reducing, terminal end of galactose-containing polysaccharides as found on the cell surface.

Abstract
Citrus canning processing water contains a valuable and renewable source of biopolymers and bioactive compounds including pectic polysaccharides. Upgrading these processing wastes can not only alleviate environmental pollution but also add value to the commodity's production. In a previous study we recovered pectic polysaccharides from citrus canning processing water. In the present study, pectic polysaccharides recycled from citrus canning processing water was depolymerized by an optimized Fenton system. The hydrolyzate was fractionated via size-exclusion chromatography into six fractions: 500 Da < LMP1 < 3 kDa; 3 kDa < LMP2 < 5 kDa; 5 kDa < LMP3 < 12 kDa; 12 kDa < LMP4 < 25 kDa; 25 kDa < LMP5 < 100 kDa and LMP6 > 10 wDa. Structure analyses showed that LMP1 were homogalacturonans-enriched non-esterified polysaccharides. While LMP2 contained both HG and rhamnogalacturonan-I (RG-I). Further antitumor assay showed that in comparison with the native pectic polysaccharide with moderate antitumor activity, both LMP1 and LMP2 possessed significant antitumor activity, while the inhibitory effect of LMP1 was higher than that of LMP2, suggesting that the biological properties of LMPs was influenced by structural characteristics, including molecular weight and monosaccharide composition.

Abstract
Interactions between galectins and polysaccharides are crucial to many biological processes, and yet these are some of the least understood, usually being limited to studies with small saccharides and short oligosaccharides. The present study is focused on human galectin-3 (Gal-3) interactions with a 60 kDa rhamnogalacturonan RG-I-4 that we use as a model to garner information as to how galectins interact with large polysaccharides, as well as to develop this agent as a therapeutic against human disease. Gal-3 is unique among galectins, because as the only chimera-type, it has a long N-terminal tail (NT) that has long puzzled investigators due to its dynamic, disordered nature and presence of numerous prolines. Here, we use 15N-1H heteronuclear single quantum coherence NMR spectroscopy to demonstrate that multiple sites on RG-I-4 provide epitopes for binding to three sites on 15N-labeled Gal-3, two within its carbohydrate recognition domain (CRD) and one at a novel site within the NT encompassing the first 40 residues that are highly conserved among all species of Gal-3. Moreover, strong binding of RG-I-4 to the Gal-3 NT occurs on a very slow time scale, suggesting that it may be mediated by cis-trans proline isomerization, a well-recognized modulator of many biological activities. The NT binding epitope within RG-I-4 appears to reside primarily in the side chains of the polysaccharide, some of which are galactans. Our results provide new insight into the role of the NT in Gal-3 function.

Abstract
Galectins are β-galcotosid-binding lectins. The function of galectins varies with their tissue-specific and subcellular location, and their binding to carbohydrates makes them key players in several intra- and extracellular processes where they bind to glycosylated proteins and lipids. In humans, there are 12 identified galectins, some with tissue-specific distribution. Galectins are found inside cells and in the nucleus, cytosol, and organelles, as well as extracellularly. Galectin-1, -2, -3, -4, -7, -8, -9, and -12 can all induce T-cell apoptosis and modulate inflammation. In the context of metabolic control and loss of the same in, for example, diabetes, galectin-1, -2, -3, -9, and -12 are especially interesting. This review presents information on galectins relevant to the control of inflammation and metabolism and the potential to target galectins for therapeutic purposes.

Abstract
Pectins are plant cell wall natural heteropolysaccharides composed mainly of α-1-4 d-galacturonic acid units, which may or may not be methyl esterified, possesses neutral sugars branching that harbor functional moieties. Physicochemical features as pH, temperature, ions concentration, and cosolute presence, affect directly the extraction yield and gelling capacity of pectins. The chemical and structural features of this polysaccharide enables its interaction with a wide range of molecules, a property that scientists profit from to form new composite matrices for target/controlled delivery of therapeutic molecules, genes or cells. Considered a prebiotic dietary fiber, pectins meetmany regulations easily, regarding health applications within the pharmaceutical industry as a raw material and as an agent for the prevention of cancer. Thus, this review lists many emergent pectin-based composite materials which will probably palliate the impact of obesity, diabetes and heart disease, aid to forestall actual epidemics, expand the ken of food additives and food products design.

Abstract
Galectin-3 is a versatile protein orchestrating several physiological and pathophysiological processes in the human body. In the last decade, considerable interest in galectin-3 has emerged because of its potential role as a biotarget. Galectin-3 is differentially expressed depending on the tissue type, however its expression can be induced under conditions of tissue injury or stress. Galectin-3 overexpression and secretion is associated with several diseases and is extensively studied in the context of fibrosis, heart failure, atherosclerosis and diabetes mellitus. Monomeric (extracellular) galectin-3 usually undergoes further "activation" which significantly broadens the spectrum of biological activity mainly by modifying its carbohydrate-binding properties. Self-interactions of this protein appear to play a crucial role in regulating the extracellular activities of this protein, however there is limited and controversial data on the mechanisms involved. We therefore summarize (recent) literature in this area and describe galectin-3 from a binding perspective providing novel insights into mechanisms by which galectin-3 is known to be "activated" and how such activation may be regulated in pathophysiological scenarios.

Abstract
BACKGROUND Pectin and especially modified citrus pectin possesses anticancer activity. Hence, the current study investigated anticancer activity of ultrasonic-modified sweet potato pectin (SPP) on HT-29 cells to assess its potential as a cancer therapeutic agent. METHOD The effect of ultrasonic treatment on SPP molecular weight, galacturonic acid content, degree of methoxylation, and neutral sugar was investigated. Moreover, the effect of sonicated variant on human HT-29 cell proliferation was assessed by MTT assay, cell cytotoxicity, and apoptosis by Annexin V/PI flow cytometer and caspase-3 activity was studied. RESULTS AND DISCUSSION Sonication led up to seven-fold decrease in molecular weight. The degree of methoxylation (DM) decreased more than two-fold. Moreover, the galacturonic acid (GalA) content increased up to 92%, arabinose and galactose content increased. The SSPP inhibited cell proliferation with the IC50 values 0.5 mg/ml and 0.75 mg/ml for 400 W and 200 W SSPP, respectively. Moreover, 14.41 ± 1.64% cell cytotoxicity was elicited by 400 W SSPP and 6.83 ± 0.80% by 200 W SSPP. Both SSPPs induced apoptosis with 400 W SSPP eliciting 19.42% and 42.21% apoptosis at 0.1 and 0.5 mg/ml, while 200 W SSPP induced 13.79% and 39.50% apoptosis at 0.1 and 0.5 mg/ml, respectively. SSPP activity increased with both increased concentration and sonication intensity.

Abstract
Papaya (Carica papaya L.) is a fleshy fruit with a rapid pulp softening during ripening. Ripening events are accompanied by gradual depolymerization of pectic polysaccharides, including homogalacturonans, rhamnogalacturonans, arabinogalactans, and their modified forms. During intermediate phases of papaya ripening, partial depolymerization of pectin to small size with decreased branching had enhanced pectin anti-cancer properties. These properties were lost with continued decomposition at later phases of ripening. Pectin extracted from intermediate phases of papaya ripening markedly decreased cell viability, induced necroptosis, and delayed culture wound closing in three types of immortalized cancer cell lines. The possible explanation for these observations is that papaya pectins extracted from the third day after harvesting have disrupted interaction between cancer cells and the extracellular matrix proteins, enhancing cell detachment and promoting apoptosis/necroptosis. The anticancer activity of papaya pectin is dependent on the presence and the branch of arabinogalactan type II (AGII) structure. These are first reports of AGII in papaya pulp and the first reports of an in vitro biological activity of papaya pectins that were modified by natural action of ripening-induced pectinolytic enzymes. Identification of the specific pectin branching structures presents a biological route to enhancing anti-cancer properties in papaya and other climacteric fruits.

Macromolecular assemblies of complex polysaccharides with galectin-3 and their synergistic effects on function. Biochem J 2017; 474:3849-3868.

Abstract
Although pectin-derived polysaccharides can antagonize galectin function in various pathological disorders, the nature of their binding interactions needs to be better defined for developing them as drugs. Moreover, given their relatively large size and complexity, pectin-derived polysaccharides are also useful as model systems to assess inter-polysaccharide and protein-polysaccharide interactions. Here, we investigated interactions between galectin-3 (Gal-3) and pectin-derived polysaccharides: a rhamnogalacturonan (RG) and two homogalacturonans (HGs). BioLayer Interferometry and fluorescence-linked immunosorbent assays indicate that these polysaccharides bind Gal-3 with macroscopic or apparent KD values of 49 nM, 46 µM, and 138 µM, respectively. 15N-1H heteronuclear single quantum coherence (HSQC) NMR studies reveal that these polysaccharides interact primarily with the F-face of the Gal-3 carbohydrate recognition domain. Even though their binding to Gal-3 does not inhibit Gal-3-mediated T-cell apoptosis and only weakly attenuates hemagglutination, their combination in specific proportions increases activity synergistically along with avidity for Gal-3. This suggests that RG and HG polysaccharides act in concert, a proposal supported by polysaccharide particle size measurements and 13C-1H HSQC data. Our model has HG interacting with RG to promote increased avidity of RG for Gal-3, likely by exposing additional lectin-binding sites on the RG. Overall, the present study contributes to our understanding of how complex HG and RG polysaccharides interact with Gal-3.

Abstract
A rhamnogalacturonan I domain, named RG-I-3A, was prepared from ginseng pectin by pectinase digestion and chromatography separation. Monosaccharide composition analysis revealed that it was mainly composed of galacturonic acid, rhamnose, galactose, and arabinose in a molar ratio of 32.5:11.2:31.9:16.5, with a molecular weight of 50 kDa. Partial acid hydrolysis, monoclonal antibody detection, and NMR spectra analysis suggested RG-I-3A was composed of →4)-α-GalpA-(1→2)-α-Rhap-(1→disaccharide repeating units as backbone, with β-1,4-galactan, α-1,5-arabinan, AG-I, and AG-II side chains substituted via the O-4 of Rhap. Galectin-3-mediated hemagglutination and biolayer interferometry assay indicated that RG-I-3A had inhibitory activity on galectin-3. These findings suggest the potential use of this ginseng RG-I domain as a galectin-3 inhibitor in drug development applications.

Abstract
Galactomannan (PSP001) isolated from the fruit rind of Punica granatum was demonstrated as an excellent antioxidant, immunomodulatory and anticancer agent both in vitro and in vivo models. Since the most lethal and debilitating attribute of cancer cells is their ability to evolve to a state of malignancy, with key features like increased angiogenesis, invasion, migration, colony formation, and metastasis, the present study focused on evaluating the effects of the galactomannan on tumor and malignancy. PSP001 effectively reduced the neovascularization in chick embryos highlighting its potential as an angiogenic inhibitor. Furthermore, the invasion, migration and clonogenic capacity of human and murine cancer cells were dramatically inhibited by PSP001. Evaluation of the molecular mechanism of its unique potential revealed the down regulation of key players including VEGF, MMP-2, and MMP-9 with marked elevation of TIMP-1 and TIMP-2. The anti-metastatic potential of PSP001 tested in pulmonary metastasis C57BL/6 mice model deciphered the combinatorial administration with vincristine deliberated better survival rates and decreased metastatic index. The angiogenic inhibition potential of PSP001 was further proved with peritoneal angiogenesis assay in BALB/c mice ascitic tumor model. The outcomes of the current investigation highlight the mode of action of antitumor galactomannan in the reduction of tumor malignancy.

Abstract
Melanoma is a malignant neoplasm of major concern because of its high mortality rate and failure of chemotherapy. Previously we have shown that galectin-3, a galactose specific lectin, plays a pivotal role in the initiation of metastasis. It was hypothesized that blocking galectin-3 with galactose rich dietary pectic polymer would inhibit metastasis. The current study analyzes the preventive effect and mode of action of a pectic polymer from Swallow Root (Decalepis hamiltonii) in a preventative study of B16F10 cells lung colonization. Matrix metalloproteinase (MMPs) activity was assayed by zymography. Apoptotic/proliferative markers and cytokines were analyzed by immunoassay. Results indicated ~88% inhibition of lung colonization by SRPP as compared to 60% by CPP and only 7% by GRPP. Further molecular analysis revealed that galectin-3 blockade was associated with down regulation of MMPs and NFκB. Activation of caspases supported the apoptotic effect of SRPP. Infiltration of inflammatory cells into the lung was evidenced by presence of CD11b+ cells and release of the pro-inflammatory cytokine-IL-17, indicating inflammation during the cancer cell colonization process. SRPP enhanced the release of IL-12 that enables the reduction of inflammation. Our data for the first time indicate the effective anti-metastatic effect of SRPP due to both galectin-3 blockade and immunomodulation.

Abstract
BACKGROUND Antioxidant, cyto/DNA protective potentials are known to offer significant protection against free radical induced injury to cells or tissues and cellular damages that are envisaged in various diseases including chronic diseases like cancer, diabetes, etc, while galectin-3 inhibitory potentials are known to block or delay the process of metastasis in cancer. Antioxidant, cyto/DNA protection and galectin-3 inhibitory potentials were examined in pectic polysaccharides (PPs) and pectic oligosaccharides (POs) from four types of two varieties of tomatoes such as Sour (Mallika local variety) raw (SrRT-SrRTPP, SrRTPO), Sour ripe (SrRIT-SrRITPP, SrRITPO), Sweet (Rashmi local variety) raw (SwRT-SwRTPP, SwRTPO) and Sweet ripe (SwRIT-SwRITPP and SwRITPO). RESULTS Results indicate that unripe PPs and POs show approximately four- to five-fold better galectin-3 inhibitory property than ripe ones. An approximately nine- to 10-fold increase in galectin-3 inhibitory activity in sour variety was observed. The IC50 as determined by free radical scavenging (FRS), red blood cell (RBC) and DNA protection assays revealed reduction in FRS and RBC protective potencies in pectic oligosaccharides (POs) than pectic polysaccharides (PPs), supporting the fact that phenolics contribute towards these activities. Loss of activity could be attributed to the hydrolysis of certain phenolics during the ripening process as well as during conversion of PPs to POs. CONCLUSION This study, for the first time, showed changes in bioactivity profiling in unripened and ripened conditions in tomato. Precise alterations in biomolecular components, such as bound cinnamyl/ferulyl and vanillic acid derivatives, along with alterations in sugar composition that reflect changes in antioxidants, cyto/DNA protective and antimetastatic potentials, have been delineated. © 2016 Society of Chemical Industry.

Abstract
Although several approaches have been used to evaluate binding of carbohydrates to lectins, results are not always comparable, especially with larger polysaccharides. Here, we quantitatively assessed and compared binding of pectin-derived polysaccharides to galectin-3 (Gal-3) using five methods: surface plasmon resonance (SPR), bio-layer interferometry (BLI), fluorescence polarization (FP), competitive fluorescence-linked immunosorbance (cFLISA), and the well-known cell-based hemagglutination assay (G3H). Our studies revealed that whereas Gal-3-pectin binding parameters determined by SPR and BLI were comparable and correlated with inhibitory potencies from the G3H assay, results using FP and cFLISA assays were highly variable and depended greatly on the probe and mass of the polysaccharide. In the cFLISA assay, for example, pectins showed no inhibition when using the DTAF-labeled asialofetuin probe, but did when using a DTAF-labeled pectin probe. And the FP approach with the DTAF-lactose probe did not work on polysaccharides and large galactan chains, although it did work well with smaller galactans. Nevertheless, even though results derived from all of these methods are in general agreement, derived KD, IC50, and MIC values do differ. Our results reflect the variability using various techniques and therefore will be useful to investigators who are developing pectin-derived Gal-3 antagonists as anti-cancer agents.

Abstract
Some complex plant-derived polysaccharides, such as modified citrus pectins and galactomannans, have been shown to have promising anti-inflammatory and anti-cancer effects. Most reports propose or claim that these effects are due to interaction of the polysaccharides with galectins because the polysaccharides contain galactose-containing side chains that might bind this class of lectin. However, their direct binding to and/or inhibition of the evolutionarily conserved galactoside-binding site of galectins has not been demonstrated. Using a well established fluorescence anisotropy assay, we tested the direct interaction of several such polysaccharides with physiological concentrations of a panel of galectins. The bioactive pectic samples tested were very poor inhibitors of the canonical galactoside-binding site for the tested galectins, with IC50 values >10 mg/ml for a few or in most cases no inhibitory activity at all. The galactomannan Davanat® was more active, albeit not a strong inhibitor (IC50 values ranging from 3 to 20 mg/ml depending on the galectin). Pure synthetic oligosaccharide fragments found in the side chains and backbone of pectins and galactomannans were additionally tested. The most commonly found galactan configuration in pectins had no inhibition of the galectins tested. Galactosylated tri- and pentamannosides, representing the structure of Davanat®, had an inhibitory effect of galectins comparable with that of free galactose. Further evaluation using cell-based assays, indirectly linked to galectin-3 inhibition, showed no inhibition of galectin-3 by the polysaccharides. These data suggest that the physiological effects of these plant polysaccharides are not due to inhibition of the canonical galectin carbohydrate-binding site.
