“…However, because of an unfavorable relation of the heparin antiviral effect and unintended bleeding events, this is of limited clinical use. The results of our study demonstrate that heparin in the presence of magnesium chloride [ 18 , 20 , 21 ] leads to an enhanced antiviral function. This is accompanied by a conformational change induced by the presence of Mg 2+ depopulating the conformation that is believed to be responsible for the anti-coagulation effect of heparin.…”

“…It was described in previous studies that the binding of heparin to different metals resulted in a conformational change and that this can reduce the inhibitory function of heparin in the coagulation cascade and therefore modulate the activity of heparin [ 18 , 19 , 20 , 21 , 22 , 23 ]. Moreover, it was found that Ca 2+ ions show a stronger affinity to heparin than Mg 2+ ions [ 20 ], yet, Mg 2+ but not Ca 2+ can be applied clinically without side effects [ 24 ].…”

“…Hao et al demonstrated using NMR and FTIR measurements that metal atom interacts with the carbonyl oxygen of the polyvinylpyrrolidone (PVP) polymer and, based on the data, hypothesized possible coordination with amine group [ 64 ]. For sugar-based moieties, it was evidenced that, in glucuronic, as well as galacturonic acid, the complexation with a trivalent ion, such as Eu 3+ , occurred between the carboxylic moiety, the ring oxygen and the C-4 hydroxyl group [ 65 , 66 ].…”

“…The reduction of the measured rates in the presence of heparin is summarized in (Table 4). It should be noted that in the supersaturation calculations in the presence of unfractionated heparin (H4L), complex formation between calcium ions (Ca 2+ ) and dissolved heparin was taken into consideration (Karpukhin, Feofanova, Nikolaeva, Mamontov, & Dobrynina, 2006). The reduction of the rate of crystal growth due to the presence of heparin in the supersaturated solutions is shown in (Figure 15).…”
