Bayoumi, Mahitab;Arafa, Mona G.;Nasr, Maha;Sammour, Omaima A. research published 《 Nobiletin-loaded composite penetration enhancer vesicles restore the normal miRNA expression and the chief defence antioxidant levels in skin cancer》, the research content is summarized as follows. Skin cancer is one of the most dangerous diseases, leading to massive losses and high death rates worldwide. Topical delivery of nutraceuticals is considered a suitable approach for efficient and safe treatment of skin cancer. Nobiletin; a flavone occurring in citrus fruits has been reported to inhibit proliferation of carcinogenesis since 1990s, is a promising candidate in this regard. Nobiletin was loaded in various vesicular systems to improve its cytotoxicity against skin cancer. Vesicles were prepared using the thin film hydration method, and characterized for particle size, zeta potential, entrapment efficiency, TEM, ex-vivo skin deposition and phys. stability. Nobiletin-loaded composite penetration enhancer vesicles (PEVs) and composite transfersomes exhibited particle size 126.70 ± 11.80 nm, 110.10 ± 0.90 nm, zeta potential + 6.10 ± 0.40 mV, + 9.80± 2.60 mV, entrapment efficiency 93.50% ±3.60, 95.60% ± 1.50 and total skin deposition 95.30% ± 3.40, 100.00% ± 2.80, resp. These formulations were selected for cytotoxicity study on epidermoid carcinoma cell line (A431). Nobiletin-loaded composite PEVs displayed the lowest IC₅₀ value, thus was selected for the in vivo study, where it restored skin condition in DMBA induced skin carcinogenesis mice, as delineated by histol. and immuno-histochem. anal., biochem. assessment of skin oxidative stress biomarkers, in addition to miRNA21 and miRNA29A. The outcomes confirmed that nobiletin- loaded composite PEVs is an efficient delivery system combating skin cancer.

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. Electric Literature of 111-90-0.

Bondre, Ruchika M.;Kanojiya, Pranita S.;Wadetwar, Rita N.;Kangali, Priya S. research published 《 Sustained vaginal delivery of in situ gel containing Voriconazole nanostructured lipid carrier: formulation, in vitro and ex vivo evaluation》, the research content is summarized as follows. Voriconazole (VOZ) is an antifungal drug having poor aqueous solubility VOZ nanostructured lipid carrier (VNLC) was prepared by using melt emulsification followed by ultrasonication technique. The VNLCs were optimized by 32 full factorial design using Design-Expert software. The optimized VNLC had a particle size, ζ potential and entrapment efficiency of 205.8 nm, -27.1 mV and 78.85%, resp. The optimized VNLC was further loaded in thermosensitive in situ gel. In vitro release studies of VNLC gel showed sustained release of the drug (98.84 ± 1.26%) for up to 24 h. The ex vivo permeation studies showed higher penetration for the VNLC gel as compared to plain VOZ gel. The in vitro antifungal assay showed higher efficacy of VNLC than that of plain VOZ. The HET-CAM test of the VNLC gel showed no irritation and thus was found to be suitable for vaginal administration. Thus, it can be concluded that the developed VNLC gel showed a sustained release pattern with higher drug localization in the vaginal tissue and thus can offer improved treatment of vaginal candidiasis.

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.

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.

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.
