New hybrid liposomes based on cationic amphiphiles with different structures of the head group (cetyltrimethylammonium bromide (CTAB), 3-hexadecyl-1-hydroxyethylimidazolium (IA-16(OH)), 1-(butylcarbamoyl)oxyethyl-3-hexadecylimidazolium (IAC 16(Bu)), and hexadecylmethylpyrrolidinium (PR-16)) were developed for transdermal administration nonsteroidal anti-inflammatory drugs. The surfactant/lipid compositions studied to obtain stable high functionality. hydrodynamic diameter was ∼110 nm. An admixture surfactants PC improves physicochemical properties vesicles diffusion rate prolongs release Liposomal diclofenac sodium (DS) ketoprofen (KP) tested (using Franz cells) penetration. Drug monitoring 48 h demonstrated that maximum DS KP penetration through synthetic membranes (Strat-M) is characterized by values 255 ± 2 186 3 μg/cm2, respectively. influence surfactant (stability, profile, permeability) shown first time. While drug specificity evident release, permeability increases as follows: conventional < CTAB/PC PR-16/PC IAC-16(Bu)/PC IA-16(OH)/PC both medicines. rat paw edema model used assess effect leader formulation in vivo. It found liposomal are effective relieving edema. should be noted DS-loaded highest therapeutic efficacy compared vesicles.

Synthesis, Properties, and Biomedical Application of Dicationic Gemini Surfactants with Dodecane Spacer and Carbamate Fragments

International Journal of Molecular Sciences, Год журнала: 2023, Номер 24(15), С. 12312 - 12312

Опубликована: Авг. 1, 2023

A synthesis procedure and aggregation properties of a new homologous series dicationic gemini surfactants with dodecane spacer two carbamate fragments (N,N'-dialkyl-N,N'-bis(2-(ethylcarbamoyloxy)ethyl)-N,N'-dimethyldodecan-1,6-diammonium dibromide, n-12-n(Et), where n = 10, 12, 14) were comprehensively described. The critical micelle concentrations obtained using tensiometry, conductometry, spectrophotometry, fluorimetry. thermodynamic parameters adsorption micellization, i.e., maximum surface excess (Гmax), the area per surfactant molecule (Amin), degree counterion binding (β), Gibbs free energy micellization (∆Gmic), calculated. Functional activity surfactants, including solubilizing capacity toward Orange OT indomethacin, incorporation into lipid bilayer, minimum inhibitory concentration, bactericidal fungicidal concentrations, was determined.

Supramolecular Strategy for the Design of Nanocarriers for Drugs and Natural Bioactives: Current State of the Art (A Review)

Russian Journal of General Chemistry, Год журнала: 2023, Номер 93(7), С. 1867 - 1899

Опубликована: Июль 1, 2023

Abstract The review focuses on the lipid based nanocarriers, with special attention paid to natural bioactive payloads. First, micelles and microemulsions are considered as very attractive colloidal nanocontainers that allow for marked improving solubility of hydrophobic bioactives. Further, liposomal vehicles reviewed, both advantages limitations discussed. Literature assay covers up-to-date information about last three five years, although brief background is given pioneer works addressing liposomes their evolution from bench bedside. Final part devoted modern modifications vesicular nanocarriers which can be adapted specific administration way due improved targeting properties, permeability, mucoadhesiveness possibility cross biological barriers. Therein, such kinds transfersomes, niosomes, ethosomes, chitosomes evaluated; separate sections focus formulations, i.e., phytosomes invasomes.

Oxime Therapy for Brain AChE Reactivation and Neuroprotection after Organophosphate Poisoning

Pharmaceutics, Год журнала: 2022, Номер 14(9), С. 1950 - 1950

One of the main problems in treatment poisoning with organophosphorus (OPs) inhibitors acetylcholinesterase (AChE) is low ability existing reactivators AChE that are used as antidotes to cross blood-brain barrier (BBB). In this work, modified cationic liposomes were developed can penetrate through BBB and deliver reactivator pralidoxime chloride (2-PAM) into brain. Liposomes obtained on basis phosphatidylcholine imidazolium surfactants. To obtain composition optimized terms charge, stability, toxicity, molar ratio surfactant/lipid was varied. For systems, physicochemical parameters, release profiles substrates (rhodamine B, 2-PAM), hemolytic activity cause hemagglutination evaluated. Screening liposome penetration BBB, analysis 2-PAM pharmacokinetics, vivo reactivation showed readily pass brain reactivate rats poisoned paraoxon (POX) by 25%. first time, an assessment made loaded reduce death neurons brains mice. It shown intravenous administration liposomal significantly POX-induced neuronal hippocampus.
