Many of the active constituents of drug or medicines were originally derived from medicinal plants. Iranian Borage are still being used in regular basis. Selenium (Se) is an essential mineral nutrient for animal and human growth. The aim of this research was to determine the effect of (2, 4, 8 and 16 mg L-1) of as sodium selenate (Na2SeO4) and as sodium selenite (Na2SeO3) on some important properties of Iranian Borage in factorial based on Randomized Complete Block Design via four steps: 2 true leaves stage, ten leaves, 2 wk and 1 wk before flowering. The traits were evaluated during flowering period. Results showed that the highest shoot fresh and dry weight and shoot length, total alkaloid, essential oil percentage were obtained by 4 mg L-1 sodium selenate at the end of flowering. In addition, 4 mg L-1 sodium selenate concentration significantly improved flower yield (diameter, number, weight). The plants were treated with 8 mg L-1 sodium selenate, the higher total phenols and flavonoids, antioxidant activity, soluble sugars, root and fresh weight was seen at end of flowering. When the plants were sprayed with 4 mg L-1 sodium selenite higher total chlorophyll was observed at full of flowering. 16 mg L-1 sodium selenite released the maximum Se acclimation in the petals. 20 composites were discovered containing -Pinene (23.61%) with sodium selenate in 4 mg L-1. Generally, selenium sources significantly improved morpho-physiol. and phytochem.

Mosquito-borne diseases are a consistent problem in Vietnam. Addnl., freshwater snail species are agricultural pests and are known to be intermediate hosts for several parasitic worms. There is a need for new and complementary botanical pesticidal agents for controlling these pests and essential oils have shown promise. In this work, essential oils from 2 species of Callicarpa (C. rubella and C. sinuata) and 4 species of Premna (P. chevalieri, P. corymbosa, P. maclurei, and P. tomentosa) were screened for mosquito larvicidal activity against Aedes albopictus and Culex quinquefasciatus and for molluscicidal activity against 3 freshwater snail species, Gyraulus convexiusculus, Pomacea canaliculata, and Tarebia granifera. Callicarpa rubella essential oil showed exceptional larvicidal activity against Cx. quinquefasciatus with 24-h LC50 of 9.8¦Ìg/mL. In addition to C. rubella, the essential oils of P. chevalieri and P. tomentosa showed notable molluscicidal activities against P. canaliculata with LC90 values ¡Ü20¦Ìg/mL. These Callicarpa and Premna essential oils were all rich in sesquiterpenes and should be considered for continued investigation as botanical pesticidal agents.

The “”millifluidic”” technique could be considered as a novel approach for encapsulation of bioactive compounds and has a promising perspective in the field of food engineering or pharmaceutical science. In this study, we aim to optimize the encapsulation of cinnamon essential oil (CEO) by droplet-based millifluidic technique with four responses: encapsulation efficiency (EE), loading capacity (LC), sphericity factor (SF) and size of calcium-alginate millicapsules. The effects of alginate concentration (20-30 g/L), flow rate of alginate (1-1.6 mL/min), and flow rate of CEO (0.6-0.8 mL/min) were considered by a Box-Behnken design. The best concentration of chitosan as a coating layer on the optimized samples was selected based on the Young modulus of millicapsules. The regression models showed the significant effect (p < 0.05) of the three variables on the characteristics of millicapsules. The optimal millicapsules with 3.58 ¡À 0.23 mm diameter and 0.96 ¡À 0.01 S F showed 98.96 ¡À 1.2% and 70.14 ¡À 1.8% EE and LC, resp. SEM images exhibited a rough external surface which changed to a rigid and smooth surface through the chitosan coating. The results of DSC and FTIR tests demonstrated the CEO entrapment in the millicapsules without any chem. interaction with the encapsulant materials. The disarray of crystallinity structure in XRD patterns revealed the successful encapsulation of CEO in the millicapsules. The non-Fickian case II in the mouth and small intestine and anomalous transport in the stomach were the main release mechanisms in the coated millicapsules. The release profile of CEO also fitted well with Ritger-Peppas model.

Amination of carboranes has a good application prospect in organic and pharmaceutical synthesis. However, the current methods used for this transformation suffer from limitations. Herein, the authors report a practical method for a highly regioselective formation of a B-N bond by Pd(II)-catalyzed B(9)-H amination of o- and m-carboranes in hexafluoroisopropanol (HFIP) with different N sources under air atm. The Ag salt and HFIP solvent play critical roles in the present protocol. The mechanistic study reveals that the Ag salt acts as a Lewis acid to promote the electrophilic palladation step by forming a heterobimetallic active catalyst PdAg(OAc)3; the strong H-bond-donating ability and low nucleophilicity of HFIP enhance the electrophilic ability of Pd(II). It is believed that these N-containing carboranes are potentially of great importance in the synthesis of new pharmaceuticals.

This study was conducted to construct a multifunctional nanodrug delivery system (NDDS) to deplete glutathione (GSH) in tumor cells and amplify oxidative stress, enhancing the synergistic effect of chemotherapy and photodynamic therapy (PDT). L-Buthionine-sulfoximine (BSO) and chlorin e6 (Ce6) were loaded into mesoporous silicon nanoparticles (MSN), and then MSN were modified with oxidized hyaluronic acid (OHA) as a pore-blocking agent. Cisplatin (Pt(II)) was further loaded by a coordination reaction with carboxyl groups in OHA to yield a multifunctional NDDS (denoted as MSN@OHA-Ce6/BSO/Pt). The physicochem. properties and antitumor activity of the prepared nanoparticles were characterized in detail. In vitro and in vivo experiments demonstrated that OHA was shed from MSN@OHA-Ce6/BSO/Pt under acidic conditions in tumors, resulting in the release of free BSO, Ce6, and Pt(II). The released BSO could reduce intracellular GSH expression by 48.8%, effectively enhancing the PDT effect of Ce6 and the chemotherapy effect of Pt(II). Finally, the tumor inhibitory rate (vs saline) reached 73.8% ¡À 2.5% for MSN@OHA-Ce6/BSO/Pt in A549/DDP tumor-bearing nude mice. Therefore, the multifunctional NDDS significantly enhanced the synergistic effect of PDT and chemotherapy.

cf. ibid. 25,229(1962). On the basis of testing 15 sulfonamide derivatives for diuretic action in rats, 6 compounds [4 highly active: hydrochlorothiazide(HCT), 5-chlorohydrochlorothiazide(HCT-55), benzthiazide(CT-S), and 3-diethylaminomethylhydrochlorothiazide(HCT-16); one moderately active: chlorothiazide(CT); and one inactive: 3-(3,4-dimethoxy-2-ethoxycarbonylphenyl)hydrochlorothiazide(HCT-18)] were chosen for comparative study on physiol. disposition in rats. A modification of the method of Baer, et al. (CA 53, 11639f) was used for the determination of these compounds in biol. materials. After an oral dose of 20 mg./kg., the rate of disappearance of the various compounds from the gastrointestinal tract was found to follow the decreasing order of HCT-55, CT-S, HCT-16, HCT, CT, and HCT-18. This order roughly parallels their oil-water partition coefficients with the exception of HCT-18, which was found to have the highest partition coefficient, although absorbed rather slowly. CT was demonstrated to have the lowest partition coefficient, which may explain its relatively slow rate of absorption from gastrointestinal epithelium. In addition, its low pKa value (the pKa1 of CT was found to be 6.7, while those of all other compounds investigated were between 9.0-9.2) may also affect its rate of absorption. For all compounds given orally, the highest concentrations were found in the kidneys, though three patterns of tissue distribution were observed. CT, HCT, and HCT-55 were all characterized by a specific affinity for the kidney tissue and very low levels in other organs; DSA was distributed rather nonspecifically in various tissues; while for CT-S and HCT-16, equally high levels were found both in the kidneys and in the liver. When given orally, the rate of excretion of the compounds in the urine was found to be essentially parallel to the rapidity of disappearance from the gastrointestinal tract, i.e., HCT-55 > CT-S > HCT > HCT-16 > CT. After intravenous injection, nearly all of the administered dose of CT-S and HCT was found in the first five-hr. urine. The percentages of urinary excretion of HCT-55, HCT-16, CT, DSA, and HCT-18 were 92, 84, 79, 58, and 29%, resp. The possible relation between the characteristics of the renal transport of these compounds and their diuretic potencies are discussed in some detail.
