Increasing amount of evidence suggests that age-related dysregulation of neuronal Ca2+ homeostasis may play a proximal role in the pathogenesis of Alzheimer's disease, as impaired Ca2+ can cause synaptic deficits and contribute to the accumulation of Aβ plaques and neurofibrillary tangles.Ca2+ disruption is known to be mostly involved in all pathologies of Alzheimer's disease, the use of chemical agents or small molecules specific for Ca2+ channels, or the treatment of proteins on the plasma membrane and intracellular organelle membranes for correction is quite possible. Neuronal dysregulation of Ca2+ may open up a new approach to the prevention and treatment of Alzheimer's disease. The article shows the possible competition between the polyphenols PС-6, PС-7 and glutamate for the area of regulation of the opening of ion channels of ionotropic NMDA-receptors in the brain of rats.

The antithrombotic effect of modified sulfated polysaccharides on a model of thromboplastin-induced thrombosis was investigated, which made it possible to evaluate the effectiveness of sulfated polysaccharides as a direct anticoagulant that increases the tolerance of animals to effects causing intravascular thrombosis.

Experimental studies and analyses of new compounds with different mechanisms of action on systemic haemostasis are relevant for the identification and development of potential pharmacological preparations. The modified sulphated polysaccharides with anticoagulant and antithrombin activity were studied for haemostasis. Platelet-rich plasma was obtained by centrifugation at 200g for 10 minutes. The remaining citrate blood was further centrifuged at 1500g for 10 min to obtain platelet-poor plasma. The antithrombin activity of the compounds was evaluated In vitro by their effect on the recalcification time, thrombin and prothrombin time of rabbit and human blood plasma stabilized with a 3.8% sodium citrate solution in the ratio 9:1. The results showed that the anticoagulant activity of the studied sulphates increased with an increasing degree of sulphation. Sulphated polysaccharides showed strong anticoagulant activity In vitro. The experimental results showed a significant increase in the coagulation time of blood plasma in tests for prothrombin and thrombin time. These properties of these components are of particular interest, and further detailed studies of the physicochemical characteristics and mechanisms of action of these molecules should be performed, which will eventually allow them to be used as heparin-like drugs.
