The Meerwein-Ponndorf-Verley (MPV) reaction is an attractive approach to selectively reduce carbonyl groups, and the design of advanced catalysts is the key for these kinds of interesting reactions. Herein, we fabricated a novel zirconium organoborate using 1,4-benzenediboronic acid (BDB) as the precursor for MPV reduction. The prepared Zr-BDB had excellent catalytic performance for the MPV reduction of various biomass-derived carbonyl compounds (i.e., levulinate esters, aldehydes and ketones). More importantly, the number of borate groups on the ligands significantly affected the catalytic activity of the Zr-organic ligand hybrids, owing to the activation role of borate groups on hydroxyl groups in the hydrogen source. Detailed investigations revealed that the excellent performance of Zr-BDB was contributed by the synergetic effect of Zr4+ and borate. Notably, this is the first work to enhance the activity of Zr-based catalysts in MPV reactions using borate groups.

The Name is Benzyl Alcohol. Through research, I have a further understanding and discovery of 100-51-6.

The present study evaluates the chemical profiling of the essential oil of a halophyte, L. maritima (LmEO), and its protective potential against CCl4-induced oxidative stress in rats. Forty compounds have been identified in LmEO. The major components are alpha-pinene (3.51%), benzyl alcohol (8.65%), linalool (22.43%), pulegone (3.33%), 1-phenyl butanone (7.33%), globulol (4.32%), gamma-terpinene (6.15%), terpinen-4-ol (4.31%), alpha-terpineol (3.9%), ledol (3.59%), epi-alpha-cadinol (3.05%) and alpha-cadinol (4.91%). In comparison with the CCl4-intoxicated group, LmEO treatment resulted in decreased liver serum marker enzymes, decreased lipid peroxidation and increased antioxidant enzyme levels, with overall further amelioration of oxidative stress. The administration of LmEO to CCl4-treated rats at a dose of 250 mg kg(-1) body weight significantly reduced the toxic effects and the oxidative stress on the liver, thus validating the traditional medicinal claim of this plant. Moreover, the anti-inflammatory activity of LmEO was evaluated in lipopolysaccharide-stimulated murine RAW 264.7 cells. Our oil could modulate the inflammatory mode of the macrophages by causing reduction in iNOS and COX2 enzymes as well as in IL-1 beta, IL-6, and TNF-alpha cytokine levels. These findings suggest that LmEO exerts anti-inflammatory effects by regulating the expression of inflammatory cytokines.

Recommanded Product: m-Methoxyphenol. I found the field of Chemistry very interesting. Saw the article Expanding the Family of Fluorescent Coumarin[4]arenes: Improved Synthesis, pi-Extension, and Characterization published in 2019.0, Reprint Addresses Venkatakrishnan, P (corresponding author), Indian Inst Technol Madras, Dept Chem, Chennai 600036, Tamil Nadu, India.. The CAS is 150-19-6. Through research, I have a further understanding and discovery of m-Methoxyphenol.

A novel series of bicyclic fluorescent heterocalixarenes – C-alkyl coumarin[4]arenes – with built-in chirality has been synthesized successfully in excellent yields under well-optimized, improved reaction conditions. Further, structural elaboration (including pi-extension) of coumarin[4]arenes has been demonstrated by using Pd-catalyzed Suzuki and Sonogashira cross-coupling methods. All of these macrocycles are shown to possess averaged C-4-symmetric conformation in solution as opposed to the coumarin[4]arene tetratriflate derivative of C-2 symmetry in the solid state. Finally, the macrocyclic coumarin[4]arenes reveal UV/near-UV absorption and visible blue emission in solution. Such a visible blue luminescence of this macrocycle highlights its potential for sensing, bioimaging, and light-emissive applications.

The Name is 4-Hydroxyquinolin-2(1H)-one. Through research, I have a further understanding and discovery of 86-95-3.

Inhibition of the host RNA polyadenylating polymerases, PAPD5 and PAPD7 (PAPD5/7), with dihydroquinolizinone, a small orally available, molecule, results in a rapid and selective degradation of hepatitis B virus (HBV) RNA, and hence reduction in the amounts of viral gene products. DHQ, is a first in class investigational agent and could represent an entirely new category of HBV antivirals. PAPD5 and PAPD7 are noncanonical, cell specified, polyadenylating polymerases, also called terminal nucleotidyl transferases 4B and 4A (TENT4B/A), respectively. They are involved in the degradation of poor-quality cell transcripts, mostly noncoding RNAs and in the maturation of a sub-set of transcripts. They also appear to play a role in shielding some mRNA from degradation. The results of studies with DHQ, along with other recent findings, provide evidence that repression of the PAPD5/7 arm of the cell RNA quality control pathway, causes a profound (multifold) reduction rather than increase, in the amount of HBV pre-genomic, pre-core and HBsAg mRNA levels in tissue culture and animal models, as well. In this review we will briefly discuss the need for new HBV therapeutics and provide background about HBV transcription. We also discuss cellular degradation of host transcripts, as it relates to a new family of anti-HBV drugs that interfere with these processes. Finally, since HBV mRNA maturation appears to be selectively sensitive to PAPD5/7 inhibition in hepatocytes, we discuss the possibility of targeting host RNA quality control as an antiviral strategy.

We describe the synthesis, characterization, and in vitro antibacterial evaluation of a library of novel compounds based on 1,2,3-triazolo phosphonate framework along with the evaluation of DNA gyrase inhibitory potential of a promising molecule in silico. Preparation of these compounds was carried out via a multistep sequence comprising of the Abramov reaction followed by the Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) as the key steps. Various alpha-hydroxyphosphonate derivatives containing either a secondary or tertiary alcohol at the alpha position were prepared. When screened for their antibacterial activities in vitro using a Gram-positive (Staphylococcus aureus) and three Gram-negative (Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa) strains, majority of these derivatives exhibited reasonable to good effects with the analogue 5k being active against all the strains. The SAR analysis indicated that the activity was influenced by the position of the alpha-hydroxyphosphonate moiety as well as the substituent present on the benzene ring attached to the 1,2,3-triazole ring. Moreover, the compound 5k showed strong interactions with the DNA active site when docked into the DNA gyrase in silico. Thus, the 1,2,3-triazolo phosphonate derivative 5k appeared to be a novel and promising hit molecule that deserves further study as a potential antibacterial agent.

A series of triphenyl substituted pyrimidines as analogous of colchicine and combretastatin A-4 was synthesized and evaluated for the antiproliferative potential. The compounds were screened against MDA-MB-231, HCT-116 and HT-29 cell lines using MTT assay. Most of the compounds displayed antiproliferative activity in low to sub micro molar concentration. Amongst the synthesized derivatives, compounds HK-2, HK-10 and HK-13 were found to be effective against all the three cancer cell lines. HK-2 exhibited IC50 values of 3.39 mu M, 4.78 mu M and 4.23 mu M, HK-10 showed IC50 values of 0.81 mu M, 5.89 mu M, 4.96 mu M and HK-13 showed IC50 values 3.24 mu M, 4.93 mu M and 4.73 mu M against MDA-MB-231, HCT-116 and HT-29 cancer cell lines, respectively. HK-10 was found to be the most potent compound in the series with IC50 values of 0.81 mu M against MDA-MB-231. In the cell cycle analysis, HK-2 and HK-10 showed cell arrest at G2/M phase of the cell cycle while HK-13 inhibited cell growth at the G1/G0 phase. All the three compounds showed cell death induced through apoptosis. In the docking studies, HK-2, HK-10 and HK-13 were found to fit well in the colchicine binding site of the tubulin. Some of the compounds in the current series were found to be promising against all the three cancer cell lines and may act as potent leads for further development.

Atkamine is a complex marine pyrroloiminoquinone alkaloid that comprises a heptacyclic scaffold bearing five different heterocycles and four contiguous stereocenters, and therefore it is a highly challenging target for synthetic chemists. We herein reported a modular synthetic strategy toward this alkaloid, featuring a formal [5 + 2] annulation and an asymmetric Michael addition. The efficient synthesis of the long-chain aliphatic aldehyde and chiral amino acetal fragments have been achieved. A simplified tetracyclic intermediate bearing the core structure of atkamine has been successfully constructed through the formal [5 + 2] annulation.
