Pehlivan Karakas, Fatma;Sahin, Gunce;Ucar Turker, Arzu;Verma, Sandeep Kumar research published 《 Impacts of heavy metal, high temperature, and UV radiation exposures on Bellis perennis L. (common daisy): Comparison of phenolic constituents and antioxidant potential (enzymatic and non-enzymatic)》, the research content is summarized as follows. Bellis perennis L., common daisy, is a beneficial medicinal plant used in folk medicine to treat skin diseases, wounds, sore throats, common colds, inflammation, and rheumatism. The objective of this study was to determine the effect of 4 different abiotic stress applications [mercury chloride (HgCl2), copper sulfate (CuSO4), high temperature (45°C) and UV radiation (UV)] on individual phenolic constituents, non-enzymic antioxidant activities (free radical scavenging activity, total phenol-flavonoid content, and proline level), and enzymic antioxidant activities [superoxide dismutase (SOD) and catalases (CAT)] in common daisy callus cultures. Quantification of the 21 phenolic substances was performed using LC-ESI-MS/MS anal. and all applied stress applications increased specific phenolic constituents comparing with control (no exposure to any stress). Heavy metal stresses (HgCl2 and CuSO4) and high temperature application enhanced the quantity of the selected phenolic substances more than UV-radiation stress. The most noticeable increased quantities were observed with high temperature stress in p-coumaric acid (51.74-fold), and with CuSO4 stress in luteolin (17.76-fold) and apigenin (15.62-fold). Chlorogenic acid was the most prevalent phenolic compound in all tested callus extract including control. Although the first highest total phenol content was obtained with HgCl2 exposure and then followed by high temperature stress, the first highest total flavonoid content was obtained with high temperature stress and then UV radiation. The antioxidant capacity was significantly enhanced (2.11 fold increase) with CuSO4 stress application. Stress-related enzymic antioxidant activity (SOD and CAT) was elevated the most with HgCl2 stress. Similarly, the highest proline content was obtained with HgCl2 treatment. These findings showed the ability of the phenolic compounds to protect common daisy against harmful heavy metals, high temperature and UV-radiation stresses. The adaptation of the callus under abiotic stress conditions developed here may be useful for the production of optimized phenolic compounds of common daisy and the exploitation of other medicinal species of interest.

Mukherjee, Nabanita;Roy, Rajsekhar;Ghosh, Satyajit;Ghosh, Surajit research published 《 Self-Assembled Antimitotic Peptide Vesicle Designed from α,β-Tubulin Heterodimer Interface for Anticancer Drug Delivery》, the research content is summarized as follows. Peptide based anticancer mol. act simultaneously as potent anticancer therapeutic as well as unique drug delivery vehicle for the targeted delivery of often cytotoxic abysmally bioavailable anticancer drugs to their designated organelle. The atypical self-assembling propensity of peptides gives rise to distinct nanostructures capable of encapsulating various drug payload. Among three different types of cytoskeletons presents in eukaryotes, microtubule plays a quintessential role during the course of cell cycle. Microtubule-targeting agents continues to be the most unwavering classes of antineoplastic drugs for the treatment of cancer. Any intervention to the dynamic tubulin assembly-disassembly process will definitely lead to complete perturbation of total cell division process. Several tubulin targeted antimitotic drugs had been designed as well as discovered to disrupt this dynamic nature of tubulin monomers either by inducing extensive polymerization or depolymerization, thereby facilitating overall cell cycle arrest. However, in cancer cells, aberrant mTOR activity causes growing resistance against numerous tubulin targeted drugs inducing metastasization, and simultaneous invasion to new healthy tissues. In recent years, numerous tubulin targeted drugs have been found to have high activity in a combination with mTOR inhibitors like tacrolimus, everolimus (RAD001), etc. but restrained bioavailability, non-specificity and quick excretion are the major impediments for the successful implementation. Combining the immense importance of protein-peptide interaction for the development of future anticancer therapeutics as well as self-assembling propensity of peptides we have taken a unique approach to craft a microtubule targeting antimitotic peptide designed from α,β-tubulin heterodimer interface, which promotes both in vitro and in vivo tubulin depolymerization, exhibiting middling toxicity towards MCF7 cells, causing cell cycle arrest. Further AFM images of this β-sheet forming peptide reveals that this peptide upon self-assembly give rise to spectacular vesicle structural characteristics which can be used as a vehicle for a combination delivery of Docetaxel and RAD001 in order to enhance their individual therapeutic potency. Encapsulation of propidium iodide and concomitant release studies suggest that Pep-4 vesicles could be a potential candidate for tubulin targeted sustained release of therapeutics. Here, our designed peptide vesicles are found to capable for the delivery of tubulin targeting drug Docetaxel along with an well-known mTOR inhibiting drug RAD001 successfully to breast cancer cell line in order to achieve a robust symbiotic effect.

The authors attempted to fabricate a novel lipid-based formulation of a lipophilic drug, nisoldipine (NISO). As NISO belongs to BCS class 2 drug, it suffers from low bioavailability (5%). Hence, the research was intended to ameliorate oral bioavailability of NISO via intestinal lymphatic transport. The NISO loaded self microemulsifying drug delivery system (SMEDDS) (NISO SMEDDS) was prepared using Peceol, Cremophor EL, and Transcutol HP. The Cremophor EL and Transcutol HP at 1:1 ratio showed maximum microemulsifying area, and average globule size was 16.78 ± 0.97 nm with PDI 0.121 ± 0.024. Cellular uptake studies (confocal microscopy and flow cytometry) using Caco-2 cells depicted higher fluorescence with coumarin-6 loaded SMEDDS as that of coumarin-6 solution which indicated deeper penetration. Mean fluorescence intensity (MFI) of coumarin-6 loaded SMEDDS was significantly improved (9.92-fold) in contrast to coumarin-6 solution The NISO SMEDDS showed enhanced permeability (5.02 times) across Caco-2 cells compared to NISO suspension. The bioavailability improvement with NISO SMEEDS was 2.14 times relative to suspension, and lymphatic uptake was involved in oral absorption of NISO SMEDDS.

Muniz, Adriana;Du, Xiaofen research published 《 Egg White Partially Substituted with Mushroom: Volatile Aroma Impartment from Mushroom and Impact of Mushroom Type, Proportion, and Cooking Method》, the research content is summarized as follows. This study investigated volatiles in 16 developed blends, in which egg whites were partially replaced with white and crimini mushrooms (0%, 10%, 20%, and 30%) and then roasted and steamed, resp. A solid-phase microextraction-gas chromatog.-mass spectrometry anal. identified ~50 volatiles in raw egg whites, while the number of volatiles increased to over 70 in steamed and roasted egg whites. Compared to raw egg white, the total volatile abundance did not significantly change, but alcs., ketones, heterocyclic compounds, and sulfurs significantly increased (p ≤ 0.05) in cooked egg whites. When egg whites were substituted with 30% mushrooms, the total volatile abundance increased 8-11 times, compared to egg white alone. The dominant volatiles in the egg white-mushroom blends were aldehydes and alcs. followed by ketones, heterocyclic compounds, and sulfurs. Increases in the mushroom proportions led to a significantly higher peak abundance of all volatiles in the blends except sulfurs. Crimini imparted higher amounts of heterocyclic compounds, and white mushrooms had higher sulfurs. Compared to the steam method, roasting significantly increased pyrazines in the blends. This study demonstrated the contribution of mushroom volatiles to egg whites, three impact factors, and the potential utilization of mushroom in food product development.

Mustapha, Abdullateef Taiye;Zhou, Cunshan research published 《 Novel assisted/unassisted ultrasound treatment: Effect on respiration rate, ethylene production, enzymes activity, volatile composition, and odor of cherry tomato》, the research content is summarized as follows. Previous studies on the application of a novel multifrequency ultrasound washing treatment have proven to be effective in guaranteeing microbial safety, and enhancing the quality of cherry tomato. Nevertheless, there is still a need to evaluate the effect of these treatments on the metabolic activity, volatile profile, and sensorial quality of the fruit. This study evaluated the above parameters of cherry tomato treated with optimized assisted and un-assisted multifrequency ultrasound. The treatments slightly enhanced the enzyme activities and inhibit ethylene production and respiration rate. The results indicated that the treatment with 20/40 kHz and aqueous ozone (0.85 ± 0.2 mg/L) for 10 min enhanced and maintained the volatile compounds (VC). Out of the 44 identified VC, one had odor activity value > 1 and thereby considered as active aroma compound contributing significantly to the aroma of the sample. E-nose anal. indicated that alc., terpenes, and some aromatic compounds are the core indicators of the significant sensors. PCA showed that the processing methods had an influence on the flavor indexes of the tomatoes. The result verified that all the washing techniques did not result in a substantial neg. effect on the tomato, and the treatment with ultrasound and ozone proved to be the best.

Autoclave treatment (AT) modified the dietary fiber composition of brewers’ spent grain (BSG), impacting its techno-processing properties. However, its impact on antioxidant properties and stability of polyphenolic compounds remain unclear. This study aimed to evaluate the influence of AT on several antioxidant activities and polyphenolic composition The results showed that AT increased ORAC (oxygen radical absorbance capacity), ABTS 2,2′ -Azinobis-(3-ethylbenzthiazoline-6-sulfonic acid), and FRAP (ferric-reducing antioxidant power) value upto 7 folds compared to the untreated BSG. The lower temperature degraded the amount of flavan-3-ols and phenolic acids. However, AT at 110°C and 130°C upgraded the phenolic acids upto 4 and 11 folds resp. Higher temperature also induced the formation of benzoic acid and (+)-catechin. UPLC-MS/MS identified several phenolic acids including syringic acid, benzoic acid, coumaric acid, ferulic acid and its derivatives, and flavan-3-ols such as (+)-catechin and (-)-epicatechin. In conclusion, AT improved the bioactivity of BSG, enhanced the amount of certains phenolic compounds and released the bioactive compounds from BSG matrixes thus offering a higher benefit for industry to utilize autoclaved BSG.

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., Category: ethers-buliding-blocks
