Congo Red as a Supramolecular Carrier System for Doxorubicin: An Approach to Understanding the Mechanism of Action. Int J Mol Sci 2022; 23:ijms23168935.

Abstract
The uptake and distribution of doxorubicin in the MCF7 line of breast-cancer cells were monitored by Raman measurements. It was demonstrated that bioavailability of doxorubicin can be significantly enhanced by applying Congo red. To understand the mechanism of doxorubicin delivery by Congo red supramolecular carriers, additional monolayer measurements and molecular dynamics simulations on model membranes were undertaken. Acting as molecular scissors, Congo red particles cut doxorubicin aggregates and incorporated them into small-sized Congo red clusters. The mixed doxorubicin/Congo red clusters were adsorbed to the hydrophilic part of the model membrane. Such behavior promoted transfer through the membrane.

The Molecular Bases of the Interaction between a Saponin from the Roots of Gypsophila paniculata L. and Model Lipid Membranes. Int J Mol Sci 2022; 23:ijms23063397. [PMID: 35328818 PMCID: PMC8949875 DOI: 10.3390/ijms23063397] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Revised: 03/14/2022] [Accepted: 03/19/2022] [Indexed: 01/27/2023] Open
Abstract
In view of the possible medical applications of saponins, the molecular structure of a GOTCAB saponin from the roots of Gypsophila paniculata L. was determined by NMR. The biological activity of saponins may depend on the interaction with cell membranes. To obtain more insight in the mechanism of membrane-related saponin function, an experimental and theoretical study was conducted. Ternary lipid systems composed of sphingomyelin, 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine, and cholesterol were used as models of mammalian cell membranes. The membrane–saponin interaction was studied experimentally by monitoring surface pressure in the monomolecular films formed at the air–aqueous subphase interface. The behavior of GOTCAB saponin in a water box and model monolayer systems was characterized by molecular dynamics simulations. The results obtained showed that, in the systems used, cholesterol had a decisive effect on the interaction between GOTCAB and phosphocholine or sphingomyelin as well as on its location within the lipid film.

Imidazole and Imidazolium Antibacterial Drugs Derived from Amino Acids. Pharmaceuticals (Basel) 2020; 13:ph13120482. [PMID: 33371256 PMCID: PMC7767166 DOI: 10.3390/ph13120482] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2020] [Revised: 12/17/2020] [Accepted: 12/17/2020] [Indexed: 11/17/2022] Open
Abstract
The antibacterial activity of imidazole and imidazolium salts is highly dependent upon their lipophilicity, which can be tuned through the introduction of different hydrophobic substituents on the nitrogen atoms of the imidazole or imidazolium ring of the molecule. Taking this into consideration, we have synthesized and characterized a series of imidazole and imidazolium salts derived from L-valine and L-phenylalanine containing different hydrophobic groups and tested their antibacterial activity against two model bacterial strains, Gram-negative E. coli and Gram-positive B. subtilis. Importantly, the results demonstrate that the minimum bactericidal concentration (MBC) of these derivatives can be tuned to fall close to the cytotoxicity values in eukaryotic cell lines. The MBC value of one of these compounds toward B. subtilis was found to be lower than the IC50 cytotoxicity value for the control cell line, HEK-293. Furthermore, the aggregation behavior of these compounds has been studied in pure water, in cell culture media, and in mixtures thereof, in order to determine if the compounds formed self-assembled aggregates at their bioactive concentrations with the aim of determining whether the monomeric species were in fact responsible for the observed antibacterial activity. Overall, these results indicate that imidazole and imidazolium compounds derived from L-valine and L-phenylalanine—with different alkyl lengths in the amide substitution—can serve as potent antibacterial agents with low cytotoxicity to human cell lines.

Abstract
Peptide surfactants have shown many potential applications in biology and medicine; however, the mechanism of their interactions with biomembranes is still unclear. This work has studied the interactions of cationic peptide gemini surfactants based on lysine spacers (12-(Lys)n-12, n = 2, 4, and 6) with model biological membranes, which are represented by the vesicles separately formed by zwitterionic unsaturated phospholipid 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC), anionic unsaturated phospholipid 1,2-dioleoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (DOPG, sodium salt) and the DOPC/DOPG (1 : 1) mixture. The experiment results show that the presence of negatively charged DOPG slightly affects the interaction manners of 12-(Lys)n-12 with the vesicles, while the interaction of 12-(Lys)2-12 with the phospholipid vesicles is significantly different from that of 12-(Lys)4-12 and 12-(Lys)6-12 with the vesicles. The binding strength decreases in the order of 12-(Lys)4-12 > 12-(Lys)6-12 > 12-(Lys)2-12. The 12-(Lys)4-12 surfactant solubilizes the DOPC vesicles, and makes the DOPC molecules join the surfactant stiff fibers and changes them into long and flexible wormlike micelles, while the 12-(Lys)6-12 and 12-(Lys)2-12 aggregates are disassembled by the DOPC vesicles, and the surfactant molecules join the DOPC vesicles and convert the unilamellar vesicles into multilamellar vesicles. This work should be helpful in understanding the interaction of peptide surfactants with phospholipid membranes.

Abstract
Arginine molecules bind to a DPPC monolayer, altering the interfacial electrostatic potential and the lateral mobility of the lipids, while having little effect on the compression isotherm of the monolayer.
