I found the field of Chemistry very interesting. Saw the article Selective Oxidation of Citronellol over Titanosilicate Catalysts published in 2020.0. SDS of cas: 100-51-6, Reprint Addresses Prech, J (corresponding author), Charles Univ Prague, Fac Sci, Dept Phys & Macromol Chem, Albertov 6, Prague 12843 2, Czech Republic.. The CAS is 100-51-6.

Citronellol is one of the most widely used fragrances for bouquetting purposes and it is a starting material for synthesis of several other terpenoids. Nevertheless, few data have been reported on citronellol selective oxidation. Accordingly, we report our findings on the selective oxidation of citronellol with hydrogen peroxide using a set of titanosilicate catalysts with different morphologies and textural properties-conventional titanium silicalite 1 (TS-1), mesoporous TS-1, layered TS-1 and silica-titania pillared TS-1 and also studying the effect of the solvent used. Epoxidation of C6=C7 double bond was the main primary reaction in this system and trace signals of C5 allylic oxidation products were observed without formation of citronellal. Due to the presence of post-synthesis introduced additional Ti sites, the silica-titania pillared TS-1 (TS-1-PITi) provided the highest conversion among the tested catalysts; nevertheless, citronellol was oxidized over all the studied catalysts including conventional TS-1; therefore, showing that it penetrates even into MFI micropores (0.55 nm in diameter). When using acetonitrile as a solvent, the conversion was proportional to the titanium content of the catalyst. When studying the effect of the solvent, acetonitrile provided the highest epoxide selectivity (55%) while in methanol, 2-propanol and 1,4-dioxane, ring opening reactions caused epoxide decomposition.

Phenols are common precursors and core structures of a variety of industrial chemicals ranging from pharmaceuticals to polymers. However, the synthesis of site-specifically substituted phenols is challenging, and thus the development of new methods for this purpose would be highly desirable. Reported here is a protocol for palladium-catalyzed ortho-selective alkylation reactions of phenols with primary alcohols by a dearomatization-rearomatization strategy, with water as the sole by-product. Various substituted phenols and primary alcohols were compatible with the standard reaction conditions. The detailed mechanism of this transformation was also investigated.

BackgroundLaminitis is a common and serve disease which caused by inflammation and pathological changes of the laminar junction. However, the pathologic mechanism remains unclear. In this study we aimed to investigate changes of the gut microbiota and metabolomics in oligofructose-induced laminitis of horses.ResultsAnimals submitted to treatment with oligofructose had lower fecal pH but higher lactic acid, histamine, and Lipopolysaccharide (LPS) in serum. Meanwhile, oligofructose altered composition of the hindgut bacterial community, demonstrated by increasing relative abundance of Lactobacillus and Megasphaera. In addition, the metabolome analysis revealed that treatment with oligofructose decreased 84 metabolites while 53 metabolites increased, such as dihydrothymine, N3,N4-Dimethyl-L-arginine, 10E,12Z-Octadecadienoic acid, and asparagine. Pathway analysis revealed that aldosterone synthesis and secretion, regulation of lipolysis in adipocytes, steroid hormone biosynthesis, pyrimidine metabolism, biosynthesis of unsaturated fatty acids, and galactose metabolism were significantly different between healthy and laminitis horses. Furthermore, correlation analysis between gut microbiota and metabolites indicated that Lactobacillus and/or Megasphaera were positively associated with the dihydrothymine, N3,N4-Dimethyl-L-arginine, 10E,12Z-Octadecadienoic acid, and asparagine.ConclusionsThese results revealed that disturbance of gut microbiota and changes of metabolites were occurred during the development of equine laminitis, and these results may provide novel insights to detect biomarkers for a better understanding of the potential mechanism and prevention strategies for laminitis in horses.

Some new fluoro-heterocyclic compounds containing thiazole and pyridine moities have been synthesized and studied for their antiproliferative activity. Thiazole derivatives have been synthesized by the reaction of alpha-halo carbonyl compounds with thiosemicarbazones. Some pyridine derivatives have been synthesized by the reaction of chalcone with cyanothioacetamide and/or malononitrile. Spectroscopic methods have been used for elucidating molecular structures of the products. Cytotoxic activity of several derivatives has been tested against human breast cancer (MCF-7), human colon cancer (HCT-116) and human liver cancer (Hep-G2) by the SRB method. Most of compounds exhibit mild effect on the tested cell lines. One of thiazolidin-4-one derivatives has been characterized by moderate to strong effect on MCF-7 cell line.

Introduction: Previous studies have reported that maternal asthma increases the risk of preterm birth. We hypothesized that inflammatory reactions caused by allergic diseases might affect the uterine environment and, subsequently, perinatal outcomes. The objective of this study was to examine the associations between allergic features among mothers and preterm pregnancy outcomes in a nationwide birth cohort. Methods: We analyzed data from pregnant women obtained from the Japanese Environment and Children’s Study (JECS), a nationwide general birth cohort study. We used binomial and multinomial logistic regression models to examine the associations between maternal allergic features and preterm birth, threatened preterm labor (TPL), and preterm premature rupture of the membrane (PPROM). Results: A total of 97,683 pregnant women were included. Prevalence of preterm birth, TPL, and PPROM was 4.7, 19.6, and 1.2%, respectively. Maternal history of allergic diseases (asthma, allergic rhinitis, allergic conjunctivitis, food allergy, drug allergy, and contact dermatitis) increased the risk of TPL(adjusted odds ratio [aOR] = 1.11 [95% CI: 1.06-1.17], aOR = 1.12 [1.08-1.16], aOR = 1.10 [1.04-1.16], aOR = 1.17 [1.09-1.26], aOR = 1.35 [1.23-1.48], and aOR = 1.34 [1.20-1.49], respectively). Although some maternal allergic features showed a negative association with preterm birth, the variables affecting preterm birth differed according to the gestational age of the fetus (22-33 weeks vs. 34-36 weeks). There were no significant associations between maternal allergic features and PPROM. Conclusion: Maternal allergic disease, except atopic dermatitis, may increase the risk of TPL. Comorbidity of maternal allergic disorders and perinatal adverse outcomes require further investigation.

Ruthenium complexes are currently significant attention in medicinal chemistry as they offer various properties which make them an appropriate choice for drug development. Herein, a series of ruthenium(II)-p-cymene-2aryl-imidazo-1,10-phenanthroline derivatives have been prepared and characterised by elemental analysis, infrared, LC-mass and NMR techniques. The structural and chemical properties shows that Ru(II) complexes have got rigidity, planarity, aromaticity, hydrogen donating and accepting capability which aids both solubility and interaction with biomolecules. The binding strength of these complexes with DNA and BSA were found to be 10(4)-10(6) M-1. The competitive displacement of ethidium bromide (EtBr) from DNA in the presence of complex reveals an intercalation or groove binding further this was supported by viscosity and in-silico studies. The cytotoxicity study of these Ru(II) complexes were conducted with two cancer cell lines (MDA-MB-231 and HeLa) and one human embryonic kidney cells (HEK-293). The study revealed that [(eta(6)-p-cymene)RuCl (kappa(2)-N,N-2-(4-fluorophenyl)-1H-imidazo[4,5-f][1,10]Phenanthroline]center dot PF6 (4e), [(eta(6)-p-cymene)RuCl(kappa(2)-N,N-2-(4-bromophenyl)-1H-imidazo[4,5-f][1,10]Phenanthroline]center dot PF6 (4f) and [(eta(6)-p-cymene)RuCl(kappa(2)-N,N-2-(4-nitrophenyl)1H-imidazo[4,5-f][1,10]Phenanthro line]center dot PF6 (4g) were found exhibit least inhibitory concentration (IC50) and high selectivity with respect to HeLa and MDA-MB-231. The activity of the Ru(II) complexes were position and substituents dependent.

Biomass burning emits large amounts of phenols, which can partition into cloud/fog drops and aerosol liquid water (ALW) and react to form aqueous secondary organic aerosol (aqSOA). Triplet excited states of organic compounds (C-3*) are likely oxidants, but there are no rate constants with highly substituted phenols that have high Henry’s law constants (K-H) and are likely important in ALW. To address this gap, we investigated the kinetics of six highly substituted phenols with the triplet excited state of 3,4-dimethoxybenzaldehyde. Second-order rate constants at pH 2 are all fast, (2.6-4.6) x 10(9) M-1 s(-1), while values at pH 5 are 2-5 times smaller. Rate constants are reasonably described by a quantitative structure-activity relationship with phenol oxidation potentials, allowing rate constants of other phenols to be predicted. Triplet-phenol kinetics are unaffected by ammonium sulfate, sodium chloride, galactose (a biomass-burning sugar), or Fe(III). In contrast, ammonium nitrate increases the rate of phenol loss by making hydroxyl radicals, while Cu(II) inhibits phenol decay. Mass yields of aqueous SOA from triplet reactions are large and range from 59 to 99%. Calculations using our data along with previous oxidant measurements indicate that phenols with high KH can be an important source of aqSOA in ALW, with 3C* typically the dominant oxidant.
