Streszczenie:

The issues of practicality in using perfluorocarbon gas transport emulsions (or pure perfluorocarbons) in severe virus-associated pneumonia treatment were considered, including those caused by coronavirus infection. Perfluorocarbons are fully fluorinated carbon compounds, on the basis of which artificial blood substitutes have been developed gas transport perfluorocarbon emulsions for medical purposes. Perfluorocarbon emulsions were widely used in the treatment of patients in critical conditions of various genesis at the end of the lastthe beginning of this century, accompanied by hypoxia, disorders of rheological properties and microcirculation of blood, perfusion of organs and tissues, intoxication, and inflammation. Large-scale clinical trials have shown a domestic plasma substitute advantage based on perfluorocarbons (perfluoroan) over foreign analogues. It is quite obvious that the inclusion of perfluorocarbon emulsions in the treatment regimens of severe virus-associated pneumonia can significantly improve this categorys treatment results after analyzing the accumulated experience. A potentially useful area of therapy for acute respiratory distress syndrome is partial fluid ventilation with the use of perfluorocarbons as respiratory fluids as shown in the result of many studies on animal models and existing clinical experience. There is no gas-liquid boundary in the alveoli, as a result of which, there is an improvement in gas exchange in the lungs and a decrease in pressure in the respiratory tract when using this technique, due to the unique physicochemical properties of liquid perfluorocarbons. A promising strategy for improving liquid ventilation effectiveness using perfluorocarbon compounds is a combination with other therapeutic methods, particularly with moderate hypothermia. Antibiotics, anesthetics, vasoactive substances, or exogenous surfactant can be delivered to the lungs during liquid ventilation with perfluorocarbons, including to the affected areas, which will enhance the drugs accumulation in the lung tissues and minimize their systemic effects. However, the indications and the optimal technique for conducting liquid ventilation of the lungs in patients with acute respiratory distress syndrome have not been determined currently. Further research is needed to clarify the indications, select devices, and determine the optimal dosage regimens for perfluorocarbons, as well as search for new technical solutions for this technique.

Abstract Hemocorrectors based on perfluorocarbon gas-transport blood-substituting emulsions are complex multiphase systems used in the biomedical field as multifunctional drugs, in particular, as gas-transport substitutes for a blood donor. The aim of this review was to discuss their physicochemical and medico-biological properties. A number of preparations from both Russian and foreign manufacturers based on chemically inert perfluorocarbon blood-substituting emulsions of a nano-size level as hemocorrectors with a gas transport function are shown. The analysis of the effect of perfluorocarbon emulsion on the blood gas transport indicators showed that perfluorocarbon particles in the bloodstream will significantly improve the conditions of gas exchange in tissues. The most important issue is the concentration of perfluorocarbon blood-substituting emulsions. The perfluorocarbon emulsions can be considered as a means of correcting the gas transport properties of blood, increasing the reserve capacity of blood cells-red blood cells to deliver oxygen to the tissues. Taking into account all facts about perfluorocarbon hemocorrectors, it can be concluded that they can be used as universal nanocarriers for the transdermal delivery of oxygen and biologically active compounds in various fields of biomedicine and cosmetology.

Streszczenie:

Background: Hypoxia renders tumor cells refractory to treatment. One way to overcome this problem is the design of drug delivery systems that contain the antitumor agent within an oxygen supply medium. Objective: to evaluate whether the perfluorocarbon liquids (capable of retaining up to 50% v/v amounts of O2 gas) can be tools for delivery of photosensitizers to hypoxic tumors. Method: We synthesized a series of compounds in which fluoroaliphatic or fluoroaromatic moieties were conjugated to the porphyrin ring in meso-positions. Two derivatives were tested as the solutions prepared either from a dimethylformamide stock (‘free’ formulation) or from a perfluorocarbon emulsion in which the photosensitizer is entrapped in the oxygenated medium. Results: In the emulsion the hydrophobic photosensitizer and the gas transporting liquid represented a biocompatible composition. Free formulations or perfluorocarbon emulsions of fluorinated porphyrins evoked little-to-null dark cytotoxicity. In contrast, each formulation triggered cell death upon light activation. Photodamage in the presence of fluorinated porphyrins was achievable not only at normoxic (20.9% O2 v/v) conditions but also in hypoxia (0.5% O2). With new compounds dissolved in the medium the cell photodamage in hypoxia was negligible whereas a significant photodamage was achieved with the emulsions of fluorinated porphyrins. The derivative with the fluoroalkyl substituent was more potent than its structurally close analog carrying the fluoroaryl moiety. Conclusion: Our new fluorinated porphyrin derivatives, especially their emulsions in which the photosensitizer and the oxygenated medium are coupled into one phase, can be perspective for photoelimination of hypoxic tumor cells.

Streszczenie:

An investigation of different methods for the immobilization of α‐amylase and trypsin on solid and liquid poly(vinyl alcohol) (PVA)‐coated perfluorocarbon supports has been made. It is found that very reactive PVA‐coated perfluorocarbon supports are produced only via the reactions between the hydroxy groups of PVA adsorbed on perfluorocarbons and 2, 2, 2‐trifluethanesulphonyl chloride (tresyl chloride), 2, 4, 6‐trichloro‐1, 3, 5‐triazine (cyanuric chloride) or p‐β‐sulphate‐(ethyl sulphonide)‐aniline (SESA), a preactivating reagent for diazotization reactions. The amounts of immobilized trypsin (specific activity and percentage recovery of enzyme activity toward casein) on solid PVA‐coated perfluorocarbon activated by tresyl chloride, SESA or cyanuric chloride were 58 mg/g (1200 units/g, 5.8%), 25 mg/g (1100 units/g, 12.4%) or 44 mg/g (1128 units/g, 7.2%) respectively. The amounts of immobilized α‐amylase (specific activity and the recovery of enzyme activity towards starch) on the same supports were 32 mg/g (4000 units/g, 7.2%), 20 mg/g (4940 units/g, 14.2%) or 29 mg/g (2725 units/g, 5.4%) respectively. Most other methods, i.e. epoxy activation (with epichlorohydrin or 1, 4‐butanediol diglycidyl ether), periodate oxidation, glutaraldehyde coupling, 1, 1'‐carbonyldi‐imidazole chemistry, 1, 1′‐carbonyldi‐imidazole chemistry in an oriented fashion, isothiocyanate chemistry and carbodiimide activation, all resulted in lower degrees of activation of PVA‐coated perfluorocarbon supports and thus correspondingly lower specific activities of the immobilized enzymes. Only the methods with SESA or cyanuric chloride are suitable for enzyme immobilization on PVA‐coated liquid perfluorocarbon emulsions. The amounts of immobilized enzymes and the specific activities of the enzymes on liquid PVA‐coated perfluorocarbon emulsion were, however, lower than those on solid PVA‐coated perfluorocarbon owing to the lower surface area of this carrier. The method with SESA seems to be the best for all applications. The addition of (NH4)2SO4 to the immobilized reactions significantly enhanced the activity recovery and the specific activity of the α‐amylase. The immobilized enzymes were stable during storage. The study demonstrates that solid PVA‐coated perfluorocarbon supports are promising carriers for enzyme immobilization.

Streszczenie:

The efficacy of photodynamic therapy (PDT) strictly depends on the availability of molecular oxygen to trigger the light-induced generation of reactive species. Fluorocarbons have an increased ability to dissolve oxygen and are attractive tools for gas delivery. We synthesized three fluorous derivatives of chlorin with peripheral polyfluoroalkyl substituents. These compounds were used as precursors for preparing nanoemulsions with perfluorodecalin as an oxygen depot. Therefore, our formulations contained hydrophobic photosensitizers capable of absorbing monochromatic light in the long wavelength region and the oxygen carrier. These modifications did not alter the photosensitizing characteristics of chlorin such as the generation of singlet oxygen, the major cytocidal species in PDT. Emulsions readily entered HCT116 colon carcinoma cells and accumulated largely in mitochondria. Illumination of cells loaded with emulsions rapidly caused peroxidation of lipids and the loss of the plasma membrane integrity (photonecrosis). Most importantly, in PDT settings, emulsions potently sensitized cells cultured under prolonged (8 weeks) hypoxia as well as cells after oxygen depletion with sodium sulfite (acute hypoxia). The photodamaging potency of emulsions in hypoxia was significantly more pronounced compared to emulsion-free counterparts. Considering a negligible dark cytotoxicity, our materials emerge as efficient and biocompatible instruments for PDT-assisted eradication of hypoxic cells.

Blood substitutes (modified hemoglobin solutions, perfluorocarbon emulsions) serve as artificial oxygen carriers and are alternatives to blood transfusions. Hemoglobin solutions mimic the sigmoidal oxygen dissociation curve of natural blood. Perflurocarbon emulsions exhibit a linear relation between Po2and dissolved oxygen. The most advanced substances may enter medicine in few years.

Streszczenie:

Background Perfluorocarbon-based oxygen carriers have been proposed as an adjunct to autologous blood conservation techniques during elective surgery. To date, the effects of perfluorocarbon emulsions at the microcirculatory level have not been studied extensively. In this study the effects of perflubron emulsion on the microcirculation after acute normovolemic hemodilution (ANH) were investigated using different colloid plasma expanders. Methods The dorsal skin fold chamber model and intravital fluorescence microscopy were used for analysis of the microcirculation in the thin striated skin muscle of conscious hamsters (body weight, 40-60 g). Measurements of microvascular perfusion and leukocyte adhesion (n = 6 animals per experimental group) were made before and at 10, 30, and 60 min after ANH (to hematocrit 0.3) with either 6% hydroxyethyl starch 200/0.6 (HES), 3.5% gelatin, 5% human serum albumin (HSA), or 6% dextran 60 (DX-60) followed by intravenous injection of 3 ml/kg body weight of a 60% weight/volume perfluorocarbon emulsion based on perflubron (perfluorooctyl bromide) emulsified with egg yolk lecithin. Results Acute normovolemic hemodilution with HES, gelatin, or HSA followed by injection of perflubron emulsion elicited no alterations of local microvascular perfusion or leukocyte-endothelium interaction as assessed in arterioles and postcapillary venules. However, ANH with DX-60 followed by injection of perflubron emulsion led to a significant reduction of erythrocyte velocity in postcapillary venules and an increase in venular leukocyte sticking that was never observed with DX-60 alone. Conclusions Hydroxyethyl starch, gelatin, and HSA are compatible with perflubron emulsion in the setting of ANH. Only DX-60 appeared to be incompatible with perflubron emulsion, as evidenced by impairment of capillary perfusion.

Streszczenie:

Self-emulsifying microbubbles, especially designed to increase the contrast of ultrasound images by the inclusion of perfluorocarbon molecules, have been studied by thermal analysis techniques. The microbubbles were made of a blend of gas (20%), surfactants (50%) and water (30%). The surfactants were mixtures of polysorbate-85, Span-80, poloxamer 188, glycerol and fluorinated surfactant (Zonyl®). Microbubbles have been characterized by means of diffusion light scattering and optical imaging. The effect of Zonyl® on encapsulation rate, as well as gas vaporization temperature and gas release temperature, has been assessed by means of Differential Scanning Calorimetry (DSC) and Thermogravimetric Analyses (TGA). Microscopy and laser granulometry techniques have been also carried out for each formulation in order to determine the number of microbubbles and their size, respectively. Moreover, stability of the emulsions has been evaluated by DSC and confronted with the results obtained from the ultrasound experiments. Average microbubble concentrations of 7.2 × 107 and 8.9 × 107 per mL were obtained for perfluorohexane and perfluoropentane based emulsions, respectively. The present study demonstrates that the amount of encapsulated perfluorocarbon increases and the gas evaporation temperature decreases with the concentration of Zonyl®. Furthermore, the best ultrasound contrast images have been obtained in vitro with the samples containing the lowest Zonyl® concentration. An explication regarding the role of Zonyl® in the emulsion/microbubbles preparations is proposed here in order to optimize self-emulsifying microbubble formulation for pharmaceutical development.

After incision of abscesses of soft tissues, dressings of the septic wounds were made using application of a perftoran. The study revealed the influence of perfluorocarbon at first stage wound healing. It was revealed a rapid decrease in inflammation, an increase of wounds healing rate, the reduction of treatment time. As a result of the study it can be recommended to apply perftoran in treatment of purulent wounds after incision of abscesses in treatment of pyogenic infections of skin and soft tissues

Intravenous perfluorocarbon (PFC) emulsions, administered with supplemental inspired O2, are being evaluated for their ability to eliminate N2 from blood and tissue prior to submarine escape, but these agents can increase the incidence of central nervous system (CNS) O2 toxicity, perhaps by enhancing O2 delivery to the brain. To assess this, we infused a PFC emulsion (Oxycyte, 6 ml/kg iv) into anesthetized rats and measured cerebral Po2 and regional cerebral blood flow (rCBF) in cortex, hippocampus, hypothalamus, and striatum with 100% O2 at 1, 3, or 5 atmospheres absolute (ATA). At 1 ATA, brain Po2 stabilized at >20 mmHg higher in animals infused with PFC emulsion than in control animals infused with saline, and rCBF fell by ∼10%. At 3 ATA, PFC emulsion raised brain Po2 >70 mmHg above control levels, and rCBF decreased by as much as 25%. At 5 ATA, brain Po2 was ≥159 mmHg above levels in control animals for the first 40 min but then rose sharply; rCBF showed a similar profile, reflecting vasoconstriction followed by hyperemia. Conscious rats were also pretreated with PFC emulsion at 3 or 6 ml/kg iv and exposed to 100% O2 at 5 ATA. At the lower dose, 80% of the animals experienced seizures by 33 min compared with 50% of the control animals. At the higher dose, seizures occurred in all rats within 25 min. At these doses, administration of PFC emulsion poses a clear risk of CNS O2 toxicity in conscious rats exposed to hyperbaric O2 at 5 ATA.
