Yetisen, Mehmet published the artcileElucidation of key aroma enhancement in cloudy lemon juices by the addition of peel oil using GC-MS-Olfactometry, Related Products of alcohols-buliding-blocks, the publication is International Journal of Food Science and Technology (2022), 57(8), 5280-5288, database is CAplus.

Volatile substances play a crucial role in the consumer preference of lemon juices. The effects of heat treatment and addition of lemon peel oil to lemon juice (Citrus limon Burm. cv. Kutdiken) on the aroma compounds were elucidated for the first time. Total phenolic, antioxidant activity, acidity, pH and color properties were also studied. Results revealed that the aroma of the juice samples comprised mostly the terpene compounds Limonene, γ-terpinene, β-pinene and α-pinene were the influential terpenes responsible for the distinctive odor of the lemon juice. The addition of the lemon peel oil increased the amounts of the aroma and aroma-active compounds Besides, the heat treatment had a pos. effect on the total phenolics and the antioxidant activity but it caused significant reduction of the aroma compounds Sensory anal. revealed that the most preferred sample was the juice with lemon peel oil added after pasteurization.

Hidalgo-Liberona, Nicole published the artcileIncreased intestinal permeability in older subjects impacts the beneficial effects of dietary polyphenols by modulating their bioavailability, Formula: C8H8O3, the publication is Journal of Agricultural and Food Chemistry (2020), 68(44), 12476-12484, database is CAplus and MEDLINE.

Polyphenols have great potential in regulating intestinal health and ameliorating pathol. conditions related to increased intestinal permeability (IP). However, the efficacy of dietary interventions with these phytochems. may significantly be influenced by interindividual variability factors affecting their bioavailability and consequent biol. activity. In the present study, urine samples collected from older subjects undergoing a crossover intervention trial with polyphenol-rich foods were subjected to metabolomics anal. for investigating the impact of increased IP on the bioavailability of polyphenols. Interestingly, urinary levels of phase II and microbiota-derived metabolites were significantly different between subjects with healthier intestinal barrier integrity and those with increased IP disruption. Our results support that this IP-dependent impaired bioavailability of polyphenols could be attributed to disturbances in the gut microbial metabolism and phase II methylation processes. Furthermore, we also observed that microbiota-derived metabolites could be largely responsible for the biol. activity elicited by dietary polyphenols against age-related disrupted IP.

Giri, Rajan published the artcileSynthesis and cancer cell cytotoxicity of substituted xanthenes, Category: alcohols-buliding-blocks, the publication is Bioorganic & Medicinal Chemistry (2010), 18(4), 1456-1463, database is CAplus and MEDLINE.

A series of substituted xanthenes was synthesized and screened for activity using DU-145, MCF-7, and HeLa cancer cell growth inhibition assays. The most potent compound, 9g (I) ([N,N-diethyl]-9-hydroxy-9-(3-methoxyphenyl)-9H-xanthene-3-carboxamide), was found to inhibit cancer cell growth with IC₅₀ values ranging from 36 to 50 μM across all three cancer cell lines. Structure-activity relationship (SAR) data is presented that indicates addnl. gains in potency may be realized through further derivatization of the compounds (e.g., the incorporation of a 7-fluoro substituent to 9g). Results are also presented that suggest the compounds function through a unique mechanism of action as compared to that of related acridine and xanthone anticancer agents (which have been shown to intercalate into DNA and inhibit topoisomerase II activity). A structural comparison of these compounds suggests the differences in function may be due to the structure of the xanthene heterocycle which adopts a nonplanar conformation about the pyran ring.

9-Aryl-9-hydroperoxyxanthenes and the corresponding dixanthenyl peroxides were decomposed with various acids under different conditions. Excess strong acid is required for optimum xanthenyl cation and hydrogen peroxide production Inductive effects of the aryl p-substituents in the 9-aryl-9-hydroperoxyxanthenes influence the course of the reaction. Treatment of the hydroperoxides with acetic acid gives the corresponding dialkyl peroxides. Increased conjugation was investigated, with 14-aryl-14-hydroperoxydibenzo[a,j]xanthenes, and has been shown to inhibit carbocation and hydrogen peroxide formation.

Kumar, Naresh published the artcileExtrapolation of hydroxytyrosol and its analogues as potential anti-inflammatory agents, COA of Formula: C8H8O3, the publication is Journal of Biomolecular Structure and Dynamics (2021), 39(15), 5588-5599, database is CAplus and MEDLINE.

Discovery of potential lead mol. is a challenging, and complex process which require lots of money, patience, and manpower. Human beings are using natural products, predominantly secondary metabolites, for this purpose since ancient time and they are still working on them as a potent source for drug discovery due to their wide structural diversity. Phenolic phytochems. such as hydroxytyrosol and tyrosol are natural antioxidant and involved in many biol. disease cure. Herein, we have carried out the quantum chem. calculations for conformational anal., geometry optimization and computation of electronic as well as optical properties of hydroxytyrosol and its analogs (1a-1k) in terms of d. functional theory by using Gaussian 09 program suite. The eventual charge transfer within the mols. has been confirmed by the anal. of frontier MOs. The mol. docking studies of 1a-1k with cyclooxygenase-2 showed the noticeable binding affinity as compared to other nonsteroidal anti-inflammatory drugs viz. aspirin, naproxen and celecoxib. Computation of pharmacokinetics and pharmacol. properties confirmed the lead/drug like potential of these screened mols. Furthermore, the mol. dynamics simulation of best three docked ligands (1f, 1h and 1k)-receptor complex and their binding free energy calculations reveals that these mols. bind in the catalytic cavity of cyclooxygenase-2 and found stable during the 100 ns of simulation.

Skarzynska, Magdalena Beata published the artcileEffectiveness of surgical approach of insertion ventilation tubes (Tympanostomy) and adenoidectomy in comparison with non-surgical approach (Watchful Waiting Approach) in children at the age between 1 and 6 and who suffer from otitis media with effusion (OME) in 12-month period of observation-the retrospective analysis, Application In Synthesis of 23828-92-4, the publication is International Journal of Environmental Research and Public Health (2021), 18(23), 12502, database is CAplus and MEDLINE.

Otitis media with effusion (OME) is one of the most common diseases in childhood. The objective was to assess clin. the effectiveness of the surgical approach (tube insertion with adenoidectomy) in comparison with the non-surgical approach (watchful waiting) during a 12-mo observation period. This study was retrospective and obtained approval from the bioethics committee. The criteria of inclusion in the first group (surgical approach) were: (1) a diagnosis of chronic otitis media with effusion in children aged between 1 and 6 years; (2) their medical history showed that they had undergone adenoidectomy and tympanostomy with the insertion of ventilation tubes (VTs). The criteria for inclusion in the second group (non-surgery) were similar to the first group except that their medical history showed they had not undergone adenoidectomy or tympanostomy with the insertion of VTs. There were 422 children included in the surgical group and 50 children in the non-surgical group, and the period of observation was 12 mo. For the entire surgical group, the number of healthy days ranged from 20 to 365, with a mean of 328.0 days (SD = 91.4).In the non-surgical group, the number of healthy days ranged from 13 to 365, with a mean of 169.2 days (SD = 127.3). The difference in the number of healthy days was statistically significant (p < 0.001). The certainty of treatment in the first group was higher than in the second group, and the number of days without recurrence was significantly higher than in the second group. In the first group, there were 71 recurrences from 422 children (16.8%), and, in the second subgroup, there were 40 recurrences of acute otitis media (AOM) from 50 children (80%). The RR was 0.21. The surgical approach in children aged 1-6 years who have been diagnosed with otitis media with effusion is reasonable and beneficial for the child.
