Abstract: Green synthesis of nanoparticles is an important tool to reduce the harmful effects associated with traditional methods. In the present investigation, we have synthesized gold nanoparticles (AuNPs) using aqueous extract prepared from fresh aerial parts (leaf and stem) of Vernonia cinerea as bioreducing agent. The visual indication of change in color from pale yellow to brown to ruby-red indicated the successful formation of the AuNPs. Characterization of nanoparticles was carried out by UV-visible spectroscopy, X-ray crystallog. (XRD), Transmission electron microscopy (TEM) and Energy dispersive X-ray anal. (EDX). UV-Vis spectra showed a specific peak at 546 nm which was the initial confirmation of the biosynthesized AuNPs. TEM images showed spherical and triangular shape of AuNPs with an average size of 25 nm. From FTIR spectrum, different functional groups were identified that could be responsible for the formation, stabilization, and capping of biosynthesized AuNPs. Aqueous plant extract and biosynthesised AuNPs were sep. tested for their antimicrobial activity against six bacterial strains and four fungal strains. Biosynthesised AuNPs (2 mg/mL) showed significantly high zone of inhibition against the selected bacterial strains as compared to the aqueous plant extract Maximum zone of inhibition (18.2 mm) was observed with AuNPs against Streptococcus pyogenes whereas comparatively less value (12.5 mm) was recorded with the plant extract Interestingly, the inhibitory activity observed against bacterial strains was even better than ampicillin. Antifungal activity recorded with AuNPs (5 mg/mL) was maximum (17.4 mm) against R. oryzae and it was higher than pos. control (17.00 mm) and plant extract (13.2 mm). The present study clearly showed that AuNPs coated with Vernonia cinerea extract were as good as pos. control in inhibiting bacterial and fungal growth. In addition, these AuNPs also showed good antioxidant potential which was comparable to ascorbic acid. Graphical abstract: [graphic not available: see fulltext].

On February 28, 2018, Kamata, Ryo; Nakajima, Daisuke; Shiraishi, Fujio published an article.SDS of cas: 4719-04-4 The title of the article was Agonistic effects of diverse xenobiotics on the constitutive androstane receptor as detected in a recombinant yeast-cell assay. And the article contained the following:

The constitutive androstane receptor (CAR) is a nuclear receptor and transcription factor regulating proteins involved in xenobiotic metabolism Agonist activation of the CAR can trigger metabolic activation and toxification as well as detoxification and clearance; accordingly, xenobiotic substances acting as CAR ligands may pose a threat to human and animal health. The authors used yeast cells transduced with the human CAR and the response pathway to measure the CAR-agonistic activities of 549 synthetic or natural compounds: 216 of the tested compounds exhibited CAR-agonistic effects. Eighty-four percent of CAR-activating compounds were aromatic compounds, and >65% of these active compounds were aromatic hydrocarbons, bisphenols, monoalkyl phenols, phthalates, styrene dimers, di-Ph ethers, organochlorines, and organophosphates. The ten most potent compounds were 4-tert-octylphenol (4tOP; reference substance), 4-nonylphenol, diethylstilbestrol, benzyl Bu phthalate, 2-(4-hydroxyphenyl)-2,4,4-trimethylchroman, o,p’-DDT, methoxychlor, di-Pr phthalate, hexestrol, and octachlorostyrene. The activities of these nine non-reference compounds exceeded 10% of the 4tOP activity. Anal. of para-monoalkyl phenols suggests that branching of the alkyl group and chlorination at the ortho position raises potency. This study provides critical information for identifying the potential of CAR-mediated toxic hazards and for understanding the relevant mechanism. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).SDS of cas: 4719-04-4

M.; Ali, D.; Shaheen, A.; Aslam, B. published an article.HPLC of Formula: 96-76-4 The title of the article was Xenobiotic thiencarbazone-methyl biotransformation investigation by bacteria Streptococcus pneumoniae, Escherichia coli and Streptococcus pyogenes. And the article contained the following:

Abstract: Xenobiotic thiencarbazone-Me is a herbicide applied on various grasses and weeds. This triazolinone pesticide may be present in soil and water after application posing deleterious effects on environment and human health. The degradation of thiencarbazone-Me was scrutinized by the pure bacterial strains including Streptococcus pneumoniae (SP), Escherichia coli (EC) and Streptococcus pyogenes (SPy). Individual bacterial suspension was prepared with herbicide solution and evaluated for a duration of 28 days. Time-dependent sampling was performed to investigate thiencarbazone-Me degradation after specific days interval. Biotransformed samples were extracted and analyzed by UV-Vis spectrophotometer and GC-MS. Biodegradation percentage achieved by SP, Spy and EC, after 28 days, was 31, 40 and 65, resp. E. coli (R2= 0.91) displayed greatest potential among all the strains to degrade the herbicide. Significant residues formed included Me 4-isocyanatosulfonyl-5-methylthiophene-3-carboxylate, 4-methanesulfonyl-benzenesulfonic acid amide and Me 3-sulfamoylthiophene-2carboxylate. Current research elucidated the effectiveness of using bacterial strains for the bioremediation of pesticides in environment. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).HPLC of Formula: 96-76-4

Cromwell, Benjamin; Mota, Lisa Cid; Levine, Mindy published an article in 2020, the title of the article was Detection of potentially toxic additives in electronic cigarettes and cigarette flavourings.COA of Formula: C14H22O And the article contains the following content:

While the popularity of electronic cigarettes (e-cigarettes) has rapidly increased in recent years, the regulation around the composition of such e-cigarettes has lagged. Many components of the e-cigarettes and liquid flavorings (e-liquids) used in these products are not disclosed, and the potential for exposure to toxic compounds via use of these products is significant. Reported herein is an anal. of the components of e-cigarettes as well as of three popular e-liquids via gas chromatog. – mass spectrometry. These results show that components of the e-cigarette contain large quantities of aromatic compounds, and that the e-liquids contain smaller quantities of potentially concerning additives. Most notably, 96% of the extract from the filter was composed of benzyl chloride, a potent DNA alkylating agent, a result which should be of significant concern to consumers, regulatory agencies, and e-cigarette manufacturers. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).COA of Formula: C14H22O

Yenuganti, Mahesh; Das, Sandip; Kulbir; Ghosh, Somnath; Bhardwaj, Prabhakar; Pawar, Sonali Shivaji; Sahoo, Subash Chandra; Kumar, Pankaj published an article in 2020, the title of the article was Nitric oxide dioxygenation (NOD) reactions of CoIII-peroxo and NiIII-peroxo complexes: NOD versus NO activation.Quality Control of 2,4-Di-tert-butylphenol And the article contains the following content:

Here, we report the nitric oxide dioxygenation (NOD) reactions of NiIII-peroxo, [(12-TMC)NiIII(O22-)]+ (NiIII-O22-, 1), and CoIII-peroxo, [(12-TMC)CoIII(O22-)]+ (CoIII-O22-, 2), complexes bearing N-tetramethylated cyclam (TMC) ligands. The reaction of complex 1 with nitric oxide (NO) generates NiII-nitrato complex [(12-TMC)NiII(NO3-)]+ (NiII-NO3-, 3). However, in contrast to the NOD reaction of 1, compound 2 produces CoII-nitrito complex, [(12-TMC)CoII(NO2-)]+ (CoII-NO2-, 4), with O2 gas formation. Results suggested the formation of a presumptive Ni-peroxynitrite ([Ni-PN]+, [Ni-ONOO-]+) intermediate, in the NOD reaction of 1, prior to the generation of NiII-NO3- (3). Although the end product of the reaction of 2 with NO is different from that of 1, the mechanistic study explored by using 2,4-di-tert-butylphenol (2,4-DTBP) suggested that the reaction of 2 with NO also occurs via a presumed Co-peroxynitrite ([Co-PN]+, [Co-ONOO-]+) intermediate. Furthermore, exploring these NOD reactions and tracking the oxygen atom using 18O-labeled hydrogen peroxide (H218O2) revealed that two oxygen atoms of 3 (NiII-18O2N16O-) and one oxygen atom of 4 (CoII-18ON16O-) are derived from the peroxo (O22-) moieties of 1 and 2, resp. This work is the first-ever report which showed the exact NO dioxygenase (NOD) enzyme catalytic cycle. Furthermore, we have also explored the NO activation of 3 and 4, and surprisingly, we observed the formation of Co-nitrosyl (5) from 4 upon reaction with NO; in contrast, 3 was unreactive towards NO. Evidence supporting the formation of [Ni-PN]+ and [Co-PN]+ intermediates is also presented.

And the article contained the following:

In the present study, the objective was to determine the quality changes of fig wine fermented with single yeast during six months of aging process. The suitable single yeast was screened, and the optimal fermentation process was determined through single-factor exptl. anal. and response surface methodol. The fig wine prepared by the optimal fermentation process then aged for six months. The results showed that the strain RV171 was the most suitable yeast among six evaluated yeast strains. The optimal process conditions were yeast addition 0.3%, fermentation temperature 28 °C, and fermentation time 9 days. During the aging process, the contents of vitamin C, total phenolics and flavonoids, as well as antioxidant activity of fig wine changed significantly. There was a pos. correlation between these bioactive substances and antioxidant capacity. In addition, significant differences existed for volatile aroma compounds in fig wine at different aging times. When fig wine is aged for one month, the content of ester volatile components was the highest, while the aroma is better than the others. The present study could provide theor. basis for the production and aging process of fig wine, which would be helpful for further investigation and application of figs to functional foods.

Harika, M.; Radhika, P. published an article in 2021, the title of the article was Phytosynthesis and characterization of silver nanoparticles from Ruellia tuberosa (l.): effect of physicochemical parameters.Recommanded Product: 2,4-Di-tert-butylphenol And the article contains the following content:

The current study focused on synthesizing silver nanoparticles (AgNPs) using Ruellia tuberosa aqueous tuber extract (RTTE) and silver nitrate (AgNO3) solution AgNPs were synthesized using an aqueous tuber extract of the medicinal herb R. tuberosa (L.). The existence of significant phytoconstituents involved in synthesizing the AgNPs was determined using the gas chromatog.-mass spectrometry (GC-MS) study. We evaluated the phys. and chem. parameters such as the effect of time, temperature, metal ion concentration, crude aqueous tuber extract concentration, and pH in the synthesis of nanoparticles. The AgNPs were characterized using UV-Vis spectroscopy, field emission SEM (FESEM), energy-dispersive X-ray spectroscopy (EDX), high-resolution transmission electron microscope (HRTEM), selected area electron diffraction (SAED), X-ray diffraction (XRD), and Fourier transform IR (FTIR) techniques. R. tuberosa tuber extract was rich in various phytochem. constituents which were identified by GC-MS. For biosynthesis, the optimal values were 1 mM AgNO3 concentration, 0.1 mL of aqueous tuber extract, and a 40 min incubation temperature of 70°C. The existence of a characteristic surface plasmon resonance (SPR) peak at 421 nm indicated the biosynthesis of AgNPs using UV-Vis spectroscopy. At higher temperatures and alk. pH, the development of AgNPs increased overtime and remained stable up to 4 wk. FESEM, EDX, HRTEM, SAED, and XRD anal. revealed that most AgNPs were spherical, with an average size distribution of 34.9 nm and a crystalline phase, face-centered cubic lattice. IR (FTIR) spectroscopic anal. revealed that hydroxyl and amino functional groups were involved in the biosynthesis and stabilization of AgNPs. The synthesis of AgNPs from R. tuberosa aqueous tuber extract was a cost-effective process and environmental friendly. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Recommanded Product: 2,4-Di-tert-butylphenol
