[PMID: 36720903 PMCID: PMC9888743 DOI: 10.1038/s41598-022-27205-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Accepted: 12/28/2022] [Indexed: 02/02/2023] Open
Abstract
New structurally diverse groups of C8-substituted caffeine derivatives were synthesized and evaluated for their chemical and biological properties. Mass spectrometry, FT-IR, and NMR characterizations of these derivatives were performed. The cytotoxic activity of the derivatives was estimated in vitro using human red blood cells (RBC) and in silico pharmacokinetic studies. The antioxidant capacity of the compounds was analyzed using a ferrous ion chelating activity assay. The ability of the derivatives to protect RBC from oxidative damage, including the oxidation of hemoglobin to methemoglobin, was assessed using a water-soluble 2,2'-azobis(2-methyl-propionamidine) dihydrochloride (AAPH) as a standard inducer of peroxyl radicals. The level of intracellular oxidative stress was assessed using the fluorescent redox probe 2',7'-dichlorodihydrofluorescein diacetate (DCF-DA). The results indicate that all derivatives are biocompatible compounds with significant antioxidant and cytoprotective potential dependent on their chemical structure. In order to explain the antioxidant and cytoprotective activity of the derivatives, a mechanism of hydrogen atom transfer (HAT), radical adduct formation (RAF), or single electron transfer (SET), as well as the specific interactions of the derivatives with the lipid bilayer of RBC membrane, have been proposed. The results show that selected modifications of the caffeine molecule enhance its antioxidant properties, which expands our knowledge of the structure-activity relationship of caffeine-based cytoprotective compounds.

The Effect of Bee Venom Peptides Melittin, Tertiapin, and Apamin on the Human Erythrocytes Ghosts: A Preliminary Study. Metabolites 2020; 10:metabo10050191. [PMID: 32413967 PMCID: PMC7281017 DOI: 10.3390/metabo10050191] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2020] [Revised: 05/05/2020] [Accepted: 05/11/2020] [Indexed: 12/13/2022] Open
Abstract
Red blood cells (RBCs) are the most abundant cells in the human blood that have been extensively studied under morphology, ultrastructure, biochemical and molecular functions. Therefore, RBCs are excellent cell models in the study of biologically active compounds like drugs and toxins on the structure and function of the cell membrane. The aim of the present study was to explore erythrocyte ghost’s proteome to identify changes occurring under the influence of three bee venom peptides-melittin, tertiapin, and apamin. We conducted preliminary experiments on the erythrocyte ghosts incubated with these peptides at their non-hemolytic concentrations. Such preparations were analyzed using liquid chromatography coupled with tandem mass spectrometry. It was found that when higher concentrations of melittin and apamin were used, fewer proteins were identified. Moreover, the results clearly indicated that apamin demonstrates the greatest influence on the RBCs ghosts proteome. Interestingly, the data also suggest that tertiapin exerted a stabilizing effect on the erythrocyte membrane. The experiments carried out show the great potential of proteomic research in the projects focused on the toxin’s properties as membrane active agents. However, to determine the specificity of the effect of selected bee venom peptides on the erythrocyte ghosts, further proteomic research should be focused on the quantitative analysis.

Abstract
Tumour cells possess or acquire various mechanisms to circumvent the cytotoxic effects of chemotherapy drugs. One such mechanism involves the overexpression of ABC transporters that facilitate the extrusion of a variety of structurally distinct chemotherapy drugs from the cytoplasm into the extracellular space. While specific ABC transporter inhibitors have been developed, many affect other ABC transporters, particularly at elevated concentrations. It is also unclear whether they show clear efficacy for combatting drug resistance in cancer patients with minimal host toxicity. In this study, we demonstrate the ability of two bile acids [β-cholanic acid (urso-cholanic acid) and deoxycholic acid] to specifically inhibit ABCC1-mediated drug transport, augmenting doxorubicin accumulation in breast and lung tumour cells selected for doxorubicin resistance through overexpression of the ABCC1 (but not ABCB1) drug transporter. The bile acids could also restore uptake and sensitivity to doxorubicin in human endothelial kidney cells genetically engineered to overexpress the ABCC1 drug transporter. These observations suggest a previously unreported role for bile acids as ABCC1 inhibitors or regulators. Given its additional properties of minimal clinical toxicity in humans and its ability to inhibit aldo-keto reductases involved in anthracycline resistance and anthracycline-induced cardiotoxicity, β-cholanic acid merits further in vivo and clinical investigation.

Perturbation of the lipid phase of a membrane is not involved in the modulation of MRP1 transport activity by flavonoids. Cell Mol Biol Lett 2008; 14:199-221.

Abstract
The expression of transmembrane transporter multidrug resistance-associated protein 1 (MRP1) confers the multidrug-resistant phenotype (MDR) on cancer cells. Since the activity of the other MDR transporter, P-glycoprotein, is sensitive to membrane perturbation, we aimed to check whether the changes in lipid bilayer properties induced by flavones (apigenin, acacetin) and flavonols (morin, myricetin) were related to their MRP1 inhibitory activity. All the flavonoids inhibited the efflux of MRP1 fluorescent substrate from human erythrocytes and breast cancer cells. Morin was also found to stimulate the ATPase activity of erythrocyte ghosts. All flavonoids intercalated into phosphatidylcholine bilayers as judged by differential scanning calorimetry and fluorescence spectroscopy with the use of two carbocyanine dyes. The model of an intramembrane localization for flavones and flavonols was proposed. No clear relationship was found between the membrane-perturbing activity of flavonoids and their potency to inhibit MRP1. We concluded that mechanisms other than perturbation of the lipid phase of membranes were responsible for inhibition of MRP1 by the flavonoids.

Abstract
Membrane rafts may act as platforms for membrane protein signalling. Rafts have also been implicated in the sorting of membrane components during membrane budding. We have studied by fluorescence microscopy cross-linking of ganglioside GM1 in the human erythrocyte membrane, and how membrane proteins CD47 and CD59 distribute in GM1 patched discoid cells and calcium-induced echinocytic cells. Patching of ganglioside(M1) (GM1) by cholera toxin subunit B (CTB) plus anti-CTB resulted in the formation of usually 40-60 GM1 patches distributed over the membrane in discoid erythrocytes. Pre-treatment of erythrocytes with methyl-beta-cyclodextrin abolished GM1 patching. GM1 patching was insensitive to pre-fixation (paraformaldehyde) of cells. Patching of GM1 did not affect the discoid shape of erythrocytes. Membrane proteins CD47 and CD59 did not accumulate into GM1 patches. No capping of patches occurred. GM1 accumulated in calcium-induced echinocytic spiculae. Also CD59, but not CD47, accumulated in spiculae. However, CD59 showed a low degree of co-localization with GM1 and frequently accumulated in different spiculae than GM1. In conclusion, our study describes a novel method for examining properties and composition of rafts. The study characterizes raft patching in the human erythrocyte membrane and emphasizes the mobility and 'echinophilicity' of GM1. Glycosyl phosphatidylinositol-anchored CD59 was identified as a mobile 'echinophilic' but 'raftophobic(GM1)' protein. Largely immobile CD47 showed no segregation.

Abstract
The presence of human multidrug resistance protein 1 (MRP1/ABCC1) in the human erythrocyte membrane is well established. In the present study, flow cytometric monitoring is introduced to identify MRP1 as the main transporter of 2',7'-bis-(3-carboxypropyl)-5-(and-6)-carboxyfluorescein (BCPCF) in the erythrocyte membrane and to facilitate inhibition and kinetic studies of MRP1-mediated transport. The ATP-dependent transport of BCPCF into human erythrocyte inside-out vesicles and, for comparison, into MRP1-expressing Sf9 cell membrane inside-out vesicles were studied. The MRP1-specific monoclonal antibody, QCRL-3 and the MRP1 inhibitor, MK-571 strongly decreased the uptake of BCPCF into both erythrocyte and MRP1-expressing Sf9 cell membrane inside-out vesicles. The inhibition profiles of cyclosporin A, verapamil, benzbromarone, and probenecid in erythrocyte membrane vesicles were typical for MRP1-mediated transport. Furthermore, kinetic constants K(m) and V(max) of BCPCF transport into erythrocyte membrane inside-out vesicles were determined in the absence and in the presence of selected inhibitors (MK-571, cyclosporin A, benzbromarone and verapamil). The presented results identified MRP1 as the major transporter of BCPCF in the human erythrocyte membrane and showed for the first time that the active transport of fluorescent substrate into inside-out vesicles can be monitored by flow cytometry.

Abstract
Flavonoids are found ubiquitously in higher plants and constitute an important component of the majority of people daily diets. The biological activities of flavonoids cover a very broad spectrum, from anticancer and antibacterial activities through to inhibition of bone resorption. In the present paper, the interactions between flavonoids and lipid bilayers as well as biological membranes and their components are reviewed, with special emphasis on the structure-activity relationships and mechanisms underlying the biological activity of flavonoids.

Abstract
The expression of multidrug resistance-associated protein (MRP1) results in ATP-dependent reduction of drugs' concentration in cancer cells, i.e., multidrug resistance (MDR). Since the majority of projects are concentrated on the search of the new MDR modulators, there are very few reports on drug-induced stimulation of MDR transporters activity. In the present work, by means of functional fluorescence assay we have shown that MRP1-mediated efflux of 2',7'-bis-(3-carboxypropyl)-5-(and-6)-carboxyfluorescein (BCPCF) out of human erythrocytes is stimulated by phenothiazine maleates that have been already identified as P-glycoprotein inhibitors. Phenothiazine maleates-induced stimulation of ATP-dependent uptake of 2',7'-bis-(3-carboxyethyl)-5-(and-6)-carboxyfluorescein (BCECF) into inside-out membrane vesicles prepared from erythrocyte membranes has been also demonstrated. Moreover, it was shown that phenothiazine maleates exerted stimulating effect on ATPase activity measured in erythrocyte membranes. To our best knowledge, this report is the first one demonstrating that compounds able to inhibit transport activity of P-glycoprotein can stimulate MRP1 transporter. We conclude that phenothiazine maleates probably exert their stimulatory effect on MRP1 by direct interaction with the protein at the site different from the substrate binding site.
