Abstract
The ongoing pandemic of COVID-19, caused by the infection of SARS-CoV-2, has generated significant harm to the world economy and taken numerous lives. This syndrome is characterized by an acute inflammatory response, mainly in the lungs and kidneys. Accumulated evidence suggests that exogenous heparin might contribute to the alleviation of COVID-19 severity through anticoagulant and various non-anticoagulant mechanisms, including heparanase inhibition, chemokine and cytokine neutralization, leukocyte trafficking interference, viral cellular-entry obstruction, and extracellular cytotoxic histone neutralization. However, the side effects of heparin and potential drawbacks of administering heparin therapy need to be considered. Here, the current heparin therapy drawbacks were covered in great detail: structure-activity relationship (SAR) mystery, potential contamination, and anticoagulant activity. Considering these unfavorable effects, specific non-anticoagulant heparin derivatives with antiviral activity could be promising candidates to treat COVID-19. Furthermore, a structurally diverse library of non-anticoagulant heparin derivatives, constructed by chemical modification and enzymatic depolymerization, would contribute to a deeper understanding of SAR mystery. In short, targeting non-anticoagulant mechanisms may produce better therapeutic effects, overcoming the side effects in patients suffering from COVID-19 and other inflammatory disorders.

Abstract
Methylene blue (MB) is one of the most common cationic dyes to detect heparin. As the sulfate residue presented in heparin was the main contributor to bind with MB, the UV performance of the MB with selectively desulfated heparin derivatives was investigated. It was found that the sulfate residue in different heparin analogues did not show the equal ability to attract MB binding. The stoichiometry of sulfate with MB among the heparin and derivatives was verified as a non-constant number. For the two selectively desulfated heparin derivatives: sulfate elimination at 6-O (6-OdeS) and N-acetylated heparin (N-deS-Acetyl), the MB to sulfate ratios were significantly higher than for heparin. For the not fully diminished sulfate at 2-O heparin derivative (2-OdeS), the MB-SO3- ratio of 2-OdeS was between 6-OdeS, N-deS-Acetlyl and heparin. Although in a distinct sulfation position, the MB-SO3- ratio of 6-OdeS and N-deS-Acetyl was almost equal, which agreed with the comparable total desulfation degree between 6-OdeS and N-deS-Acetyl. In addition, compared to heparin groups, the non-desulfated gs-HP showed no significantly different MB-SO3- ratio with heparin. The above results demonstrated that compared with the sulfate location and glycan composition of heparin, the content of sulfate was the most essential factor for the MB binding.

Abstract
Non-anticoagulant biological functions of heparin-based drugs have drawn increasing attention. However, the exploration into the non-anticoagulant activities of various low molecular weight heparins was associated with bleeding risks in clinical practice and often led to controversial conclusions due to the structural differences. In this study, we aimed to establish a process to produce a library of heparin derivatives with structural diversity and reduced/abolished anticoagulant activity through the combination of chemical modifications and enzymatic cleavage of heparins. The depolymerization characteristics of various selectively modified heparin derivatives by three heparinases were comprehensively analyzed. The order of periodate treatment and heparinase-I depolymerization was proved to significantly change the structural characteristics of the oligosaccharide products. Finally, among several heparin derivatives that screened in the bleomycin-induced cell apoptosis model, the low molecular weight partially 6-O-/N-desulfated heparins showed the strongest anti-apoptotic activities. This study provided a useful approach for future development of novel heparin-derivative medications.

Abstract
The chapter will review early and more recent seminal contributions to the discovery and characterization of heparanase and non-anticoagulant heparins inhibiting its peculiar enzymatic activity. Indeed, heparanase displays a unique versatility in degrading heparan sulfate chains of several proteoglycans expressed in all mammalian cells. This endo-β-D-glucuronidase is overexpressed in cancer, inflammation, diabetes, atherosclerosis, nephropathies and other pathologies. Starting from known low- or non-anticoagulant heparins, the search for heparanase inhibitors evolved focusing on structure-activity relationship studies and taking advantage of new chemical-physical analytical methods which have allowed characterization and sequencing of polysaccharide chains. New methods to screen heparanase inhibitors and to evaluate their mechanism of action and in vivo activity in experimental models prompted their development. New non-anticoagulant heparin derivatives endowed with anti-heparanase activity are reported. Some leads are under clinical evaluation in the oncology field (e.g., acute myeloid leukemia, multiple myeloma, pancreatic carcinoma) and in other pathological conditions (e.g., sickle cell disease, malaria, labor arrest).

Abstract
The β-galactoside-binding protein, galectin-3, is extensively involved in cancer development, progression and metastasis through multiple mechanisms. Inhibition of the galectin-3-mediated actions is increasingly considered as a promising therapeutic approach for cancer treatment. Our early studies have identified several novel galectin-3 binding inhibitors from chemical modification of the anticoagulant drug heparin. These heparin-derived galectin-3 binding inhibitors, which show no anticoagulant activity and bind to the galectin-3 canonical carbohydrate-binding site, induce galectin-3 conformational changes and inhibit galectin-3-mediated cancer cell adhesion, invasion and angiogenesis in vitro and reduce metastasis in mice. In this study, we determined the binding affinities of these heparin-derived ligands to galectin-3 using an isothermal titration calorimetry (ITC) ligand displacement approach. Such ITC experiments showed that the 2-de-O-sulphated, N-acetylated (compound E) and 6-de-O-sulphated, N-acetylated (F) heparin-derived ligands and their ultra-low molecular weight sub-fractions (E3 and F3) bind to galectin-3 with KD ranging from 0.96 to 1.32 mM.Differential scanning fluorimetry analysis revealed that, in contrast to the disaccharide ligand, N-acetyl-lactosamine, which binds to the fully folded form of galectin-3 and promotes galectin-3 thermal stability, the heparin-derived ligands preferentially bind to the unfolded state of galectin-3 and cause destabilization of the galectin-3 protein structure. These results provide molecular insights into the interaction of galectin-3 with the heparin-derived ligands and explain the previously demonstrated in vitro and in vivo effects of these binding inhibitors on galectin-3-mediated cancer cell behaviours.

Abstract
Graft-versus-host disease (GvHD) is a severe immune reaction commonly occurring after hematopoietic stem cell transplantation. The outcome of patients who do not respond to the currently used immunosuppressive drugs is poor, thus there is an urgent need for the evaluation of new therapies. Heparin has a well-known anti-inflammatory effect and heparin analogues with a low anticoagulant effect are interesting candidates as new anti-inflammatory drugs. We explored the therapeutic potential of dendritic polyglycerol sulfates (dPGS), a novel class of heparin derivatives, on murine acute GvHD in vivo. The therapeutic effect of dPGS on murine GvHD was more intense after intravenous application compared to subcutaneous injection. An increased survival rate and improved clinical scores were observed in mice treated with 5 mg/kg once a week. In these animals, there was a reduction in the percentage of CD4(+) and CD8(+) T cells, which are the main effectors of GvHD. In addition, dPGS treatment decreased the number of tumor necrosis factor alpha (TNFα)-producing T cells. Increasing the dose of dPGS reversed the positive effect on survival as well as the clinical score, which indicates a small therapeutic range. Here, we report for the first time that dPGS have a significant immunosuppressive in vivo effect in a mouse model of severe acute GvHD. Therefore, we propose to study dPGS as promising candidates for the development of potential new drugs in the treatment of steroid-refractory GvHD patients first in larger animals and later in humans.
