[More] The inhibition of α-glucosidase and α-amylase is a clinical strategy for the treatment of type II diabetes, and herbal medicines have been reported to credibly alleviate hyperglycemia. Our previous study has reported some constituents from plant or herbal sources targeted to α-glucosidase and α-amylase via molecular docking and enzymatic measurement, but the hypoglycemic potencies in cell system and mice have not been validated yet. This study was aimed to elucidate the hypoglycemic efficacy of docking selected compounds in cell assay and oral glucose and starch tolerance tests of mice. All test compounds showed the inhibition of α-glucosidase activity in Caco-2 cells. The decrease of blood sugar levels of test compounds in 30 min and 60 min of mice after OGTT and OSTT, respectively and the decreased glucose levels of test compounds were significantly varied in acarbose. Taken altogether, in vitro and in vivo experiments suggest that selected natural compounds (curcumin, antroquinonol, HCD, docosanol, tetracosanol, rutin, and actinodaphnine) via molecular docking were confirmed as potential candidates of α-glucosidase and α-amylase inhibitors for treating diabetes.

[More] An antitumor drug/esophagus stent combination can palliatively relieve malignant esophageal stricture and exert local chemotherapy to cancer. It is vital for effective treatment of cancer to control drug release and facilitate drug penetration into deep tissue after the combination is placed in the malignant strictured esophagus part. In this study, we firstly designed and prepared a novel antitumor drug/esophagus stent combination: a magnetocaloric nitinol stent coated with a bilayered film that consisted of one ethylene-vinyl acetate copolymer (EVA) layer as drug blocking layer and one EVA layer containing 10% paclitaxel (PTX) and 30% temperature sensitive phase-change fatty alcohol (1-tetradecanol, 1-hexadecanol or 1-octadecanol). The drug release and penetration into rabbit esophagus wall from the combination were investigated. It was found that, under an alternating electromagnetic field at a power of 0.1 kW, the combination was heated to 43 °C, the PTX was faster and more released from the combination, as well as the amount of PTX in esophagus tissue or its deep muscle tissue penetrated from the combination was much higher than that without alternating electromagnetic field. The pathological data showed that the combination was biocompatible and safe after placement in rabbit esophagus even under an alternating electromagnetic field. Overall, the PTX could be magnetocalorically released and effectively penetrated into esophagus wall from the PTX/nitinol stent combination.

[Less] Background and Purpose: Treatment of life-threatening fungal infections caused by Candida . . . [More] Background and Purpose: Treatment of life-threatening fungal infections caused by Candida species has become a major problem. Candida spp. are the most important causative agents of candidiasis. Allium tripedale is a medicinal plant that has been traditionally used to treat infections. In the present study, we aimed to determine the chemical compounds and antimicrobial activity of hydroalcoholic extract of A. tripedale against different species of Candida.

Materials and Methods: Phytochemical analysis was performed to identify the possible bioactive components of this extract by using gas chromatography and mass spectroscopy (GC-MS). The hydroalcoholic extract of A. tripedale were collected. Different concentrations of A. tripedale (50, 25, 12.5, and 6.25 mg/ml) were used to evaluate its antifungal activity against Candida species (C. albicans, C. parapsilosis, and C. krusei) using disk diffusion assay.

Results: The GC-MS analysis revealed the presence of 40 different phytoconstituents with peak area; the major compounds were tetracosane, hexadecanoic acid, 1-eicosanol, 1,2-dihydro-pyrido[3,2,1-kl]phenothiazin-3-one, 2-hexadecen-1-ol, and 3,7,11,15-tetramethyl. Hydroalcoholic extract showed strong antimicrobial activity (inhibition zone ⩾ 20 mm), moderate antimicrobial activity (inhibition zone < 12-20 mm), and no inhibition (zone < 12 mm). In addition, the hydroalcoholic extract exhibited the highest antimicrobial properties against C. albicans strains.

Conclusion: A. tripedale extract had a considerable inhibitory effect against various Candida species, but its highest inhibitory effect was against Candid albicans. Further investigations are required to detect the performance of this plant in the treatment of Candida infection.

[More] Objective: To design a topical vehicle that provided the optimal balance of betamethasone dipropionate penetration and retention in the skin, with minimal systemic absorption. Design: Six test formulations of betamethasone dipropionate 0.05% in vehicles contained the following penetration enhancers: elaidyl alcohol (Formulation-1), hexanol (Formulation-2), dodecanol (Formulation-3), octadecanol (Formulation-4), docosanol (Formulation-5), or oleyl alcohol (Formulation-6). Test agents were applied to human cadaver skin in static Franz-cell chambers containing receptor fluid. Measurements: Betamethasone absorption into the receptor fluid was measured over 24 hours. The distribution of betamethasone and its metabolites in the stratum corneum, epidermis, and dermis was analyzed using LC-MS/MS. The formulation with the optimal balance of penetration, permeation, retention, and minimal absorption was selected for a similar study comparing its penetration and absorption versus several commercially available betamethasone formulations. Results: Formulation-3 resulted in the highest retention of betamethasone in the skin as well as the highest steroid levels in the receptor fluid at 12 and 24 hours. Formulation-6 had the second highest retention of betamethasone in total skin, with relatively low absorption into the receptor fluid. All other variants had both lower steroid retention in the skin and lower absorption into the receptor fluid, with the exception of Formulation-2 which had higher absorption at 24 hours. Formulation-6/DFD-01 was selected for further development. Comparison of Formulation-6/DFD-01 with commercially available formulations of betamethasone dipropionate showed it had the highest steroid levels in the epidermis and dermis combined, with relatively low levels in the receptor fluid. Conclusion: Formulation-6/DFD-01 had the optimal balance of betamethasone retention in the skin, with low systemic absorption. This designed vehicle ensured retention of the corticosteroid in skin layers to maximize local efficacy while minimizing potential for hypothalamic-pituitary-adrenal suppression.

[More] Docosanol is an over-the-counter topical agent that has proved to be one of the most effective therapies for treating herpes simplex labialis. However, the mechanism by which docosanol suppresses lesion formation remains poorly understood. To elucidate its mechanism of action, we investigated the uptake of docosanol in living cells using coherent anti-Stokes Raman scattering microscopy. Based on direct visualization of the deuterated docosanol, we observed highly concentrated docosanol inside living cells 24 h after drug treatment. In addition, different spatial patterns of drug accumulation were observed in different cell lines. In keratinocytes, which are the targeted cells of docosanol, the drug molecules appeared to be docking at the periphery of the cell membrane. In contrast, the drug molecules in fibroblasts appeared to accumulate in densely packed punctate regions throughout the cytoplasm. These results suggest that this molecular imaging approach is suitable for the longitudinal tracking of drug molecules in living cells to identify cell-specific trafficking and may also have implications for elucidating the mechanism by which docosanol suppresses lesion formation.
