Formation of electrosprayed composite nanoparticles from polyvinylpyrrolidone/mangosteen pericarp extract

Mangosteen pericarp contains a lot of alpha-mangostin compounds which has very high antioxidant activity. Unfortunately, it has a low solubility in aqueous solution in which for drug delivery application. This paper reports the synthesis of polyvinylpyrrolidone (PVP) nanoparticles loaded with mangosteen pericarp extract (MPE) using the ES method. PVP was trusted as a hydrophilic matrix to carry MPE. The composition of the precursor solution and solution flow rate during the ES process were varied to control the formation of PVP/MPE composite nanoparticles. PVP/MPE composite particles obtained have some wrinkles on their surface and have a geometric average diameter range of 640 to 1534 nm with a geometric standard deviation of 1.35 to 1.65. Increasing the electrical conductivity of the precursor solution resulted in a decrease of nanoparticles’ average diameter. Also, the greater the flow rate, the larger the particles formed. The results agreed well with the droplet scaling relations for EHDA by Chen and Pui. Peak shifts in Fourier-transform infrared spectra of PVP/MPE composite nanoparticles indicated hydrogen bond formation between PVP and MPE. It also showed that MPE was successfully encapsulated in PVP matrix. Crystalline peaks of MPE disappear in the X-ray diffraction patterns of PVP/MPE composite nanoparticles, indicating amorphization of MPE after being electrosprayed by PVP. The differential scanning calorimetry study confirmed a hygroscopicity of PVP. The thermogram shows a broad endothermic peak from around 50 to 100 C as a result of dehydration. In this study, the use of flow rate during the electrospraying process only affected the geometric average diameter, did not change the functional groups, thermal properties, and crystallinity of PVP/MPE particles because they came from the same precursor solution. The results here demonstrate that the ES method can be used for polymeric-nanoparticle-composite production and as an innovation in the field of drug delivery application.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.14984-68-0. In my other articles, you can also check out more blogs about 14984-68-0

Cross-Coupling of Alkyl Redox-Active Esters with Benzophenone Imines: Tandem Photoredox and Copper Catalysis

Alkyl amines are an important class of organic compounds in medicinal and materials chemistry. Until now very have been very few methods for the synthesis of alkyl amines by metal-catalyzed cross-coupling of alkyl electrophiles with nitrogen nucleophiles. Described here is an approach to employ tandem photoredox and copper catalysis to enable the cross-coupling of alkyl N-hydroxyphthalimide esters, readily derived from alkyl carboxylic acids, with benzophenone-derived imines. Hydrolysis of the coupling products furnish alkylated primary amines. Primary, secondary, and tertiary alkyl groups can be transferred, and the coupling tolerates a diverse set of functional groups. The method allows rapid functionalization of natural products and drugs, and can be used to expedite syntheses of pharmaceuticals from readily available chemical feedstocks.

Oxidative-addition of the N-H bond of saccharin (sacH) to a triosmium centre: Synthesis, structure and reactivity of Os3(CO)10(mu-H)(mu-sac) This paper is dedicated to Professor Kazi Azam on the occasion of his retirement. A talented scientist, true gentleman, and inspiration to generations of students at Jahangirnager University.

Saccharin (sacH) is a widely-used sweetener and consequently its chemistry has been extensively studied, but here we report a rare example of its reactivity towards a multinuclear metal centre. Lightly-stabilized Os3(CO)10-n(NCMe)n (n = 1, 2) react with sacH to afford Os3(CO)10(mu-H) (mu-sac) (1) in which the sac ligand bridges an osmium-osmium vector via nitrogen and the carbonylic oxygen (mu-N,O). The reactivity of 1 towards monodentate phosphines, PR3 (R = Ph, Th, Fu), has been investigated. Carbonyl substitution affords both mono- and bis-phosphine substituted derivatives Os3(CO)9(PR3) (mu-H) (mu-sac) (2) and Os3(CO)8(PR3)2(mu-H) (mu-sac) (3) respectively. In the mono-substituted derivatives, the phosphine occupies an equatorial position on the osmium that is directly bonded to the carbonylic oxygen of saccharinate, while in the bis-(phosphine) substituted derivatives the second phosphine is bound to the remote osmium also occupying an equatorial site. In all complexes the saccharinate ligand remains in the bidentate N,O coordination mode thus playing a directing spectator role in these reactions.

Specificities of the enzymes of N-alkyltropane biosynthesis in Brugmansia and Datura

The enzymes N-methylputrescine oxidase (MPO), the tropine-forming tropinone reductase (TRI), the pseudotropine-forming tropinone reductase (TRII), the tropine:acyl-CoA transferase (TAT) and the pseudotropine:acyl-CoA transferase (PAT) extracted from transformed root cultures of Datura stramonium and a Brugmansia candida x aurea hybrid were tested for their ability to accept a range of alternative substrates. MPO activity was tested with N-alkylputrescines and N-alkylcadaverines as substrates. TRI and TRII reduction was tested against a series of N-alkylnortropinones, N- alkylnorpelletierines and structurally related ketones as substrates. TAT and PAT esterification tests used a series of N-substituted tropines, pseudotropines, pelletierinols and pseudopelletierinols as substrates to assess the formation of their respective acetyl and tigloyl esters. The results generally show that these enzymes will accept alien substrates to varying degrees. Such studies may shed some light on the overall topology of the active sites of the enzymes concerned.
