Hyaluronic Acid-Based Nanocapsules as Efficient Delivery Systems of Garlic Oil Active Components with Anticancer Activity.

ABSTRACT: Diallyl disulfide (DADS) and diallyl trisulfide (DATS) are garlic oil compounds exhibiting beneficial healthy properties including anticancer action. However, these compounds are sparingly water-soluble with a limited stability that may imply damage to blood vessels or cells after administration. Thus, their encapsulation in the oil-core nanocapsules based on a derivative of hyaluronic acid was investigated here as a way of protecting against oxidation and undesired interactions with blood and digestive track components. The nuclear magnetic resonance (1H NMR) technique was used to follow the oxidation processes. It was proved that the shell of the capsule acts as a barrier limiting the sulfur oxidation, enhancing the stability of C=C bonds in DADS and DATS. Moreover, it was shown that the encapsulation inhibited the lysis of the red blood cell membrane (mainly for DADS) and interactions with serum or digestive track components. Importantly, the biological functions and anticancer activity of DADS and DATS were preserved after encapsulation. Additionally, the nanocapsule formulations affected the migration of neoplastic cells-a desirable preliminary observation concerning the inhibition of migration. The proposed route of administration of these garlic extract components would enable reaching their higher concentrations in blood, longer circulation in a bloodstream, and thus, imply a better therapeutic effect.

Project description:The main challenges in anticancer drug design include solubility in organic and aqueous phases, bioavailability, selective targeting of specific receptors, and low toxicity. Notably, solubility, bioavailability, and receptor-specific targeting are interconnected factors that significantly influence the therapeutic efficacy of anticancer drugs. The primary objective of this study is to design novel drug delivery systems based on ionic liquids. These systems incorporate structures such as N, N, N-trimethyl-2-(((2 S,3R,4 S,5 S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2 H-pyran-2-yl)oxy)ethan-1-aminium (GTA) and (2 S,3R,4 S,5 S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)-N, N, N-trimethyltetrahydro-2 H-pyran-2-aminium (NTPA) derived from carbohydrates as cationic components, with anticancer drugs acting as anions. The goal is to investigate the effects of these novel pharmaceutical active ionic liquids on the interactions between the drugs and cell membranes. Additionally, this study examines changes in the solubility of anticancer drugs in both organic and aqueous phases after their conversion into ionic liquids. Molecular dynamics simulations (MD) and quantum mechanics calculations (QM) are employed to achieve these objectives. Known anticancer-candidate ionic liquid, such as 3-(2-((4-fluorophenyl)amino)-2-oxoethyl)-1-methyl-1 H-imidazol-3-ium-tetrafluoroborate, is considered as a reference point in our investigations. Furthermore, we aim to assess whether the direct attachment of the aminium group to the saccharide portion of the cations or the indirect attachment through a choline group significantly impacts the final properties of the designed anticancer ionic liquids. Another aim of this study is to demonstrate that QM studies need to be complemented by MD studies to provide insights into the behaviors of ionic liquids. Initially, we calculate the binding energies between cations and anions of all the ionic liquids at the B3LYP/6-311 + + G(d, p) level of theory. Subsequently, molecular dynamics simulations using GROMACS 5.2 are employed to obtain more precise information about these understudied ionic liquids. A combination of density functional theory (DFT) calculations and a solvation model based on density (SMD) is utilized to determine the solubility of free anticancer drugs and our active anticancer ionic liquids in various phases. We validate our findings by evaluating the interactions between the formulated ionic liquids and cell membranes using the DPPC model through combined MD simulations and docking procedures.
