Dangre, Pankaj V.;Gurram, Navya J.;Surana, Sanjay J.;Chalikwar, Shailesh S. research published 《 Development and Optimization of Vitamin D₃ Solid Self-Microemulsifying Drug Delivery System: Investigation of Flowability and Shelf Life》, the research content is summarized as follows. Abstract: We report herein the design of a solid self-microemulsifying drug delivery system (SMEDDS) of vitamin D3 for augmentation of its solubility and dissolution The studies employed a 32 full factorial design by employing JMP 13.2.1, software for preparation of liquid SMEDDS. Further, the prediction profiler was utilized to optimized liquid SMEDDS-Vit.D3 (OF) formulation. The solidification of liquid SMEDDS-Vit. D3 formulation was carried out by phys. adsorption over Neusilin US2 and Aerosil 200 carriers. Solid-state evaluation of SMEDDS-Vit. D3 suggested the transformation of crystalline to amorphous form of Vit. D3 which is responsible for imparting more aqueous solubility and thus enhancement in dissolution behavior. The investigation of flow behaviors viz. flow function (FF) and effective angle of wall friction (EAWF) of solid SMEDDS-Vit. D3 was performed using powder flow tester. Solid SMEDDS-Vit. D3 prepared using Neusilin US2 showed good flow behavior and hence was developed into tablets. The tablets showed good quality control parameters as per pharmacopeial standards The in vitro dissolution studies demonstrated more dissolution of Vit. D3 in SMEDDS (liquid, solid, and tablet) when compared to the unprocessed drug. The shelf life (T90) of tablets was reported to be 28.12 mo suggesting excellent stability of Vit.D3 in solid SMEDDS. In nutshell, our research works explore the utilization of SMEDDS for the oral delivery of Vit. D3 to gain maximum health-related benefits. Graphical abstract: [graphic not available: see fulltext].

Danielski, Renan;Mazzutti, Simone;Ferreira, Sandra Regina Salvador;Vitali, Luciano;Block, Jane Mara research published 《 A non-conventional approach for obtaining phenolic antioxidants from red guava (Psidium guajava L.) by-products》, the research content is summarized as follows. The recovery of phenolic antioxidants from agro-industrial byproducts using non-conventional techniques is a powerful tool to explore the bioactive potential of natural sources. Therefore, it is imperative to analyze the most suitable method to investigate a plant material’s phenolic composition This study used ultra-turrax (UTE), ultrasonic bath (BUAE), and pressurized liquid (PLE) for soluble phenolic extraction from guava’s pulp and processing waste. UTE at 25°C for 1 h yielded the highest concentration of total phenolics and flavonoids from guava pulp, while PLE for 30 min at 60°C/10 MPa presented the best performance for flavonoids and condensed tannins recovery from guava waste. PLE produced extracts with 39 phenolics and high antioxidant capacity. Besides, scopoletin, resveratrol, and naringin are being reported for the first time in this fruit. These results suggest possible alternatives for the recovery of bioactive compound, which may be used to develop nutraceuticals and/or functional foods. Practical applications : Upon guava processing, 30% of fruit’s total volume is lost in the form of byproducts (seeds, peels, and pulp leftovers). Evidence points out that this fraction, along with guava’s pulp, is rich in phenolics with antioxidant properties. An extraction procedure should be conducted to recover these compounds However, conventional techniques are laborious, time-consuming, and they generally use a large amount of toxic organic solvent. Ultra-turrax-UTE, ultrasonic bath-BUAE, and pressurized liquid-PLE are non-conventional approaches that make possible the reduction of solvents and the recovery of selected phenolics not possible with conventional techniques. These extracts could be further applied to lipid-rich foods as a natural antioxidant system and/or as an ingredient in the development of nutraceuticals and functional foods.

In the current study, a novel self-nanoemulsifying drug delivery system (SNEDDS) was developed in order to improve the oral bioavailability of delafloxacin (DLF). Various oils, surfactants and co-surfactants were screened by solubility studies. Based on solubilization, potential of DLF in various vehicles, Lauroglycol-90 (oil), Tween 80 (surfactant) and Transcutol-HP (co-surfactant) were selected for the development of DLF loaded SNEDDS (DLF-SNEDDS). Four formulas of DLF loaded SNEDDS (DLF1-DLF4) were prepared and evaluated for their droplet size, polydispersity index (PDI), zeta potential (ZP), refractive index (RI), percent transmittance (%T), thermodn. stability, emulsifying efficiency and in vitro release studies. Among developed DLF loaded SNEDDS (DLF1-DLF4), DLFI was found optimum with a droplet size (73.3 ± 6.5 nm) PDI (0.298) ZP (-22.3) RI (1.334 ± 0.05) and %T (99.2 ± 0.09). Optimized DLF loaded SNEDDS (DLF1) demonstrated a superior anti-microbial activity against tested gram pos. and gram neg. strains with no resistance. The pharmacokinetic studies showed that oral bioavailability of DLF was significantly improved (3- fold) by optimized DLF loaded SNEDDS (DLF1) in comparison to pure DLF suspension. Hence, the results of this work suggest that the developed SNEDDS could be a potential carrier in enhancing bioavailability and therapeutic efficacy of DLF.

Araujo, Gustavo Parreira;Martins, Felipe Terra;Taveira, Stephania Fleury;Cunha-Filho, Marcilio;Marreto, Ricardo Neves research published 《 Effects of Formulation and Manufacturing Process on Drug Release from Solid Self-emulsifying Drug Delivery Systems Prepared by High Shear Mixing》, the research content is summarized as follows. This study sought to investigate the influence of formulation and process factors of the high shear mixing (HSM) on the properties of solid self-emulsifying drug delivery systems (S-SEDDS) containing the model drug carvedilol (CAR). Firstly, liquid SEDDS (L-SEDDS) were prepared by mixing castor oil with different proportions of surfactant (Solutol or Kolliphor RH40) and cosolvent (Transcutol or PEG400). A miscible L-SEDDS with high drug solubility (124.3 mg/g) was selected and gave rise to 10% (m/m) CAR loaded-emulsion with reduced particle size. Then, a factorial exptl. design involving five component′s concentration and two process factors was used to study the solidification of the selected L-SEDDS by HSM. CAR content, diffractometric profile, and in vitro dissolution were determined Morphol. and flow analyses were also performed. Porous and spherical particles with mean sizes ranging from 160 to 210 μm were obtained. Particle size was not affected by any formulation factor studied. Powder flowability, in turn, was influenced by L-SEDDS and crospovidone concentration CAR in vitro dissolution from S-SEDDS was significantly increased compared to the drug as supplied and was equal (pH 1.2) or lower (pH 6.8) than that determined for L-SEDDS. Colloidal silicon dioxide decreased drug dissolution, whereas an increase in water-soluble diluent lactose and L-SEDDS concentration increased CAR dissolution The proper selection of liquid and solid constituents proved to be crucial to developing an S-SEDDS by HSM. Indeed, the results obtained here using exptl. design contribute to the production of S-SEDDS using an industrially viable process.

This study aims to investigate the possible effects of myrtle leaf extract (Myrtus communis L.) on, heart, kidney and aorta tissues in the exptl. renovascular hypertension (RVH). 32 male Wistar Albino rats were divided into four groups as control, hypertension, hypertension+ramipril, and hypertension+myrtle leaf extract treatment groups. RVH model was induced by Goldblatts 2-kidney 1-clip method. 12 wk later than the treatment blood pressures were recorded and oxidant and antioxidant parameters, tissue factor activity, and histol. anal. were determined in the kidney, heart, and aortic tissues. The blood pressure levels of the hypertension group significantly increased compared to the control group. Administration of myrtle leaf extract and ramipril significantly decreased the increased blood pressure. In the hypertension group, oxidative damage increased in the kidney, heart, and aorta tissues. In the histol. evaluation of tissues in RVH, heart muscle fibers degenerated. Bowman capsule and glomeruli dilated and tubules damaged in the kidney. Myrtle leaf extract administration regenerated the damages and degenerations. The administration of myrtle leaf extract restored the impaired oxidant-antioxidant balance in the heart, kidney and aorta tissues of hypertensive rats.

Asakawa, Daiki;Hosokai, Takuya;Nakayama, Yasuo research published 《 Experimental and Theoretical Investigation of MALDI In-Source Decay of Peptides with a Reducing Matrix: What is the Initial Fragmentation Step?》, the research content is summarized as follows. Matrix-assisted laser desorption/ionization in-source decay (MALDI-ISD) with a reducing matrix is believed to be initiated by hydrogen transfer from the matrix to the peptide. Several new matrixes have recently been developed to achieve more efficient MALDI-ISD. In particular, the use of matrixes containing aniline groups facilitates MALDI-ISD to a greater extent than that of matrixes containing phenol groups, although the N-H bond in aniline is stronger than the O-H bond in phenol. In this study, photoelectron yield spectroscopy of matrix solids revealed that conversion of the phenol group to the aniline group decreased the ionization energy of the matrix solids. Crucially, the use of a matrix with lower ionization energy has been found to result in efficient cleavage at N-Cα and disulfide bonds by MALDI-ISD. Therefore, electron association with the peptide rather than the fragmentation mechanism involving hydrogen atom attachment is proposed as the initial step of the MALDI-ISD process. In this mechanism, electron transfer from the reducing matrix to the peptide produces a peptide anion radical, which provides either a [cn+H]/[zm]• or [an]•/[ym+H] fragment pair. Fragmentation of the peptide anion radical strongly depends on the gas-phase acidity of the matrix used. Subsequently, the resultant fragments/radicals underwent a reaction in the MALDI plume, producing observable even-electron ions. Consequently, MALDI-ISD fragments are observed as both pos. and neg. ions, even though MALDI-ISD with a reducing matrix involves fragmentation of peptide anion radicals. The proposed mechanism is suitable for obtaining a better understanding of the MALDI-ISD process.

Natural products are known to control diabetes and its associated complications. Leaves of Hedera nepalensis are used to cure diabetes in the folklore system of medicines. The present study was designed to evaluate the in vivo antidiabetic and wound healing potentials of ethanol extract of Hedera nepalensis. Ethanolic extract (Hn.Cr) was prepared by maceration and was chem. characterized by HPLC methods. Antioxidant and antimicrobial properties were assessed in three in vitro models. Toxicity profile of Hn. Cr was evaluated in acute toxicol. studies. Alloxan-induced diabetes model was used to access the antidiabetic attributes of Hn.Cr. Excision wound healing model was used to access the wound healing potential of Hn. Cr in alloxan-induced diabetic rats. HPLC anal. of Hn. Cr revealed the presence of phenolic and flavonoids compounds Data of in vitro antioxidant assays showed that Hn. Cr has moderate radical scavenging potential. In vitro antimicrobial testing results revealed that Hn. Cr was active against bacterial strains (Gram +ve and Gram -ve) while no activity was observed against fungal strains used in the current study. Acute toxicity study results showed that extract was safe up to the dose of 5000 mg/kg. In vivo antidiabetic study revealed that Hn. Cr significantly (p < 0.05) reduced the blood glucose levels in a dose and time-dependent manner. Data of the excisional wound healing model indicated that Hn. Cr accelerated wound healing in diabetic rats in a time-dependent manner. The current study concludes that multicomponent Hn. Cr has antidiabetic and wound healing properties, thus, can be used as a complementary therapy to manage hyperglycemia and wounds in diabetic patients. However, furhter studies are warranted in this regard.

Synthetic Route of 530-59-6, Sinapinic acid is a chemical compound that is the dihydroxybenzoic acid derivative of sinapic acid. It has been shown to have anti-inflammatory properties in vitro and in vivo. Sinapinic acid inhibits the activity of various enzymes, such as cyclooxygenase (COX), lipoxygenase (LOX), and 5-lipoxygenase-activating protein (FLAP). It also decreases levels of adhesion molecules and downregulates inflammatory response genes. Sinapinic acid has been shown to reduce inflammation by inhibiting the formation of proinflammatory mediators, such as prostaglandin E2 or leukotriene B4, in endothelial cells and mammary epithelial cells.
Sinapic acid is a phenylpropanoid hydroxycinnamic acid with diverse biological activities. Sinapic acid inhibits collagen-induced human platelet aggregation by up to 70% in vitro (IC50 = 1.03 mM). It scavenges 2,2-diphenyl-1-picrylhydrazyl (DPPH; ) and 2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonate) (ABTS) free radicals with IC50 values of 8.3 and 5.4 μg/ml, respectively. Sinapic acid (200 μM) reduces colony formation of SW480 human colon carcinoma cells by 4-fold. It also inhibits colony formation of E. coli, S. enteritidis, and S. aureus on agar (MICs = 2.2, 2, and 1.8 mM, respectively). In vivo, sinapic acid (4 mg/kg, p.o.) increases the time spent in the open arms of the elevated plus maze by approximately 15% in mice, an effect that can be blocked by the GABAA receptor antagonists flumazenil and bicuculline. Sinapic acid is also commonly used as a matrix in protein mass spectrometry.
Sinapic acid analytical standard provided with w/w absolute assay, to be used for quantitative titration.
Sinapic acid is an hydroxycinnamic acid derivative that occurs naturally in Brassicaceae species.
cis-Sinapic acid, also known as cis-sinapate or synapitic acid, belongs to the class of organic compounds known as hydroxycinnamic acids. Hydroxycinnamic acids are compounds containing an cinnamic acid where the benzene ring is hydroxylated. cis-Sinapic acid is considered to be a practically insoluble (in water) and relatively neutral molecule. Within the cell, cis-sinapic acid is primarily located in the cytoplasm. Outside of the human body, cis-sinapic acid can be found in common pea and pulses. This makes cis-sinapic acid a potential biomarker for the consumption of these food products.
Cis-sinapic acid is a 3-(4-hydroxy-3,5-dimethoxyphenyl)prop-2-enoic acid in which the double bond has cis-configuration. It has been isolated from the shoots of alfalfa. It has a role as a plant metabolite., 530-59-6.
