Abd-Elsalam, Wessam H.;Saber, Mona M.;Abouelatta, Samar M. research published 《 Trehalosomes: Colon targeting trehalose-based green nanocarriers for the maintenance of remission in inflammatory bowel diseases》, the research content is summarized as follows. The use of non-steroidal anti-inflammatory drugs (NSAIDs) in inflammatory bowel diseases (IBDs) are contradictory between their beneficial effect in alleviating inflammation, and injurious outcomes in aggravating the symptoms of colitis. The study aimed to formulate trehalosomes (THs); innovative green trehalose-based nanocarriers, to alleviate the inflammation symptoms that might be provoked by NSAIDs in IBDs; as trehalose was proved to lighten the inflammation and the oxidative stress response, besides its resistance to the acidic conditions that rises its potentiality as a means for colon targeting. THs were fabricated using L-α-phosphatidylcholine (PL), trehalose, and transcutol, in a single step circumventing the incorporation of any organic solvent and loaded with Tenoxicam (TXM) as a model anti-inflammatory medication. A full 23 factorial design, using Design-Expert software, was established to optimize the formulation variables. The optimized formulation composed of trehalose: PL at a weight ratio of 1:1, 377.72 mg transcutol, and sonicated for 4 min, possessed a spherical shape with a size of 268.61 nm and EE% of 97.83% and released 70.22% of its drug content over 24 h. The supreme protective action of TXM loaded THs compared to TXM suspension and drug-free THs was revealed by the suppression of the inflammatory biomarkers and the improved histopathol. of the colonic tissue in male New Zealand rabbits. IL-1ss, IL-6, and TNF-alpha levels were notably dampened with TXM loaded THs, and oxidative stress markers, measured as GSH and MDA, were significantly altered. The study indicates the successful role of green THs in colon targeting and its anti-inflammatory characteristics in protecting against possible NSAIDs-driven exacerbation of colitis.

Ethers lack the hydroxyl groups of alcohols. Without the strongly polarized O―H bond, ether molecules cannot engage in hydrogen bonding with each other. 111-90-0, formula is C6H14O3, Name is Diethylene Glycol Monoethyl Ether. Ethers do have nonbonding electron pairs on their oxygen atoms, however, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. Category: ethers-buliding-blocks.

Alshehri, Sultan;Shakeel, Faiyaz;Alam, Prawez;Jouyban, Abolghasem;Martinez, Fleming research published 《 Solubility of 6-phenyl-4,5-dihydropyridazin-3(2H)-one in aqueous mixtures of Transcutol and PEG 400 revisited: Correlation and preferential solvation》, the research content is summarized as follows. Reported equilibrium mole fraction solubility values of 6-phenyl-4,5-dihydropyridazin-3(2H)-one (PDP-6) (3) in {Transcutol (1) + water (2)} and {PEG 400 (1) + water (2)} mixtures at five temperatures from T = (293.15 to 313.15) K were analyzed based on the Hildebrand solubility parameter of the resp. aqueous mixtures Cosolvency models for representing the equilibrium solubility of PDP-6 in both binary solvent systems at various temperatures were also provided for correlation/prediction purposes. Moreover, the preferential solvation parameters of PDP-6 in these aqueous-cosolvent mixtures at T = (298.15 and 313.15) K were determined by means of the “inverse Kirkwood-Buff integrals” (IKBI). PDP-6 is preferentially solvated by water in water-rich mixtures of {Transcutol (1) + water (2)} system but preferentially solvated by Transcutol in mixtures of 0.13 < x1 < 1.00. In the former case this result could be due to hydrophobic hydration around the non-polar moieties of PDP-6. Otherwise, PDP-6 is preferentially solvated by PEG 400 in all the aqueous mixtures Moreover, in the systems where preferentially solvation of PDP-6 by cosolvents are observed, these results could be due to the Lewis acidic behavior of PDP-6 in front of Transcutol or PEG 400 mols. because these cosolvents exhibit higher Lewis basic behavior than water.

Alshehri, Sultan;Shakeel, Faiyaz;Alam, Prawez;Pena, Angeles;Jouyban, Abolghasem;Martinez, Fleming research published 《 Effect of temperature and polarity on the solubility and preferential solvation of sinapic acid in aqueous mixtures of DMSO and Carbitol》, the research content is summarized as follows. Reported equilibrium mole fraction solubilities of sinapic acid (3) in {DMSO (1) + water (2)} and {Carbitol (1) + water (2)} mixtures at several temperatures were analyzed in terms of the Hildebrand solubility parameter of these aqueous mixtures Moreover, the preferential solvation parameters of sinapic acid in these aqueous saturated mixtures at (298.15 and 313.15) K were determined based on the inverse Kirkwood-Buff integrals (IKBI) as widely described in the literature. Sinapic acid is preferentially solvated by water in water-rich mixtures, i.e. (0.00 <x₁ < 0.21 in {DMSO (1) + water (2)}) and (0.00 <x₁ < 0.12 in {Carbitol (1) + water (2)}) but preferentially solvated by the cosolvents in the other mixtures composition In the former cases these results could be interpreted as a consequence of hydrophobic hydration around the non-polar moieties of sinapic acid. Moreover, in the last cases, the observed trends could be due to the Lewis acidic behavior of sinapic acid in front of DMSO or Carbitol mols. because both cosolvents exhibit higher Lewis basic character than water, as indicated by the resp. solvatochromic parameters. A single cosolvency model for representing the equilibrium solubility of sinapic acid in binary solvents at various temperatures was also provided based on a combination of Hansen solubility parameters and Jouyban-Acree model.
