A series of four new mixed-ligand copper(ii) complexes (1-4) of the type [Cu(L)(diimine)] (ClO4) [where L is 2-((1H-imidazol-2-yl)methylene)-N-phenylhydrazinecarbothioamide and the diimines are 1,10-phenanthroline (phen, 1), 2,2?-bipyridine (bpy, 2), 4,4?-dimethyl-2,2?-bipyridyl (dmbpy, 3), and 2,2?-dipyridylamine (dpa, 4)] have been successfully synthesized and characterized by various spectral techniques. The Kb values were calculated from electronic absorption spectral titration of these complexes with herring sperm DNA, and these varied in the order phen (1) > dmbpy (3) > bpy (2) > dpa (4). Electrophoresis observations revealed that these complexes (1-4) could efficiently induce single-strand breakage of pUC18 plasmid DNA in the presence of ascorbic acid. These copper complexes underwent a static quenching process with BSA. Moreover, their potential free-radical scavenging and anti-inflammatory properties were also determined using DPPH and protein denaturation techniques. These complexes showed efficient antibacterial activities against Staphylococcus aureus (Gram positive) and Pseudomonas aeruginosa (Gram negative). Furthermore, studies of their in vitro cytotoxicity against AGS cancer cells indicated promising antitumor activity with significant IC50 values.

An article , which mentions 10343-06-3, molecular formula is C14H20O10. The compound – 2,3,4,6-Tetra-o-acetyl-D-glucopyranose played an important role in people’s production and life.

Anomeric O-hetarylation of tetra-O-benzyl- and tetra-O-acetylglucose (1a, b) can be directly performed with electrondeficient heteroaromatic/heterocyclic systems 2-14, which contain imide halide moieties. The reactions were carried out in the presence of a base and led, through an exchange of the halide by the glucopyranosyloxy moiety, to the products 2a-14a, 7b-14b. Predominantly or exclusively beta-products were obtained. Systems bearing more than one imide halide moiety, such as cyanuric fluoride (15) or 5-chloro-2,4,6-trifluoropyrimidine (16), can be employed for successive anomeric O-hetarylations. Investigation of the glycosyl donor properties of O-glucosyl heteroaromatic imidates with 6-O-and 4-O-unprotected glucose derivatives 18 and 19 as acceptors and comparison of the results obtained with data for the corresponding beta-trichloroacetimidates 17abeta and 17bbeta, reveals that 2,3,5,6-tetrafluoropyridin-4-yl glucopyranosides 14abeta and 14bbeta exhibit similar properties. For specific tasks, for instance alpha-glucopyranoside formation, 14abeta may even be advantageous.

A new dinuclear copper(II) complex [Cu2(mu1,1-NCO) 2(NCO)2(dpyam)2] (dpyam = di-2-pyridylamine) has been synthesized and characterized by X-ray diffraction. Two N-bonded cyanato ligands bridge two copper ions in an end-on fashion and two others act as the N-bonded terminal ligands. The copper ion has a distorted square-pyramidal environment. The magnetic susceptibility, measured from 5 to 300 K, has revealed a weak ferromagnetic interaction between the Cu(II) atoms with a singlet-triplet energy gap (J) of 6.03 cm-1. The EPR spectrum, measured as a powdered solid at RT and 77 K, shows an S = 1/2 signal with g? = 2.08 and an unresolved g? of 2.29.

A number of pro-moieties 8a-e designed for prodrug preparation have been synthesized. The pro-moieties, containing a glucuronyl carbamate group linked to a spacer possessing a terminal carboxylic acid group, have been synthesized from isocyanates 6 and anomerically unprotected glucuronic acids 10. The requisite isocyanates had to be prepared using the Curtius rearrangement. Glucuronyl carbamates proved to be excellent substrates for human beta-glucuronidase. The pro-moieties 8a-e can be coupled to hydroxy- or amino group containing drugs. The resulting prodrugs are designed to be activated by beta-glucuronidase and to be used in ADEPT. Application is demonstrated with the synthesis of duanomycin prodrugs 12a-e.

Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view.64519-82-0, Name is (3R,4R,5R)-6-(((2S,3R,4S,5S,6R)-3,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexane-1,2,3,4,5-pentaol, molecular formula is C12H24O11.

Alcohols (CnHn+2OH) are classified into primary, secondary, and tertiary alcohols, which can be branched or unbranched. They can also feature more than one OH-group (two OH-groups = diol; three OH-groups = triol). Presently, except for ethanol and sugar alcohols, they are mainly produced from fossil-based resources, such as petroleum, gas, and coal. Methanol and ethanol have the highest annual production volume accounting for 53 and 91 million tons/year, respectively. Most alcohols are used as fuels (e.g., ethanol), solvents (e.g., butanol), and chemical intermediates. This chapter gives an overview of recent research on the production of short-chain unbranched alcohols (C1?C5), focusing in particular on propanediols (1,2- and 1,3-propanediol), butanols, and butanediols (1,4- and 2,3-butanediol). It also provides a short summary on biobased higher alcohols (>C5) including branched alcohols.
