The morphology and magnetic properties of diblock copolymer templated ferrimagnetic cobalt oxide nanoparticles are reported. Ring opening metathesis polymerization (ROMP) was used to synthesize a novel cobalt diblock copolymer, where cobalt is directly attached to the polymer chain. Gel permeation chromatography (GPC) was performed to determine molecular weight distribution. Transmission electron microscope (TEM), UV-Vis, FTIR, and vibrating sample magnetometer (VSM) were used to characterize the block copolymer nanocomposite. The nanocomposite films were weakly ferrimagnetic at room temperature. The cobalt oxide nanoparticles were uniformly dispersed within the polymer matrix with an average radius of 4.9±0.9 nm.

Plusbacin A3 is a depsipeptide antibiotic isolated from Pseudomonas sp. Although the stereochemistry at the lactone stereocenter had not been determined, biological evaluation of this compound demonstrated it to have promising antibacterial activity against vancomycin-resistant enterococci. Its mechanism of action remains to be conclusively established, but it is believed to exert its antibiotic effect through inhibition of bacterial cell wall biosynthesis. In this paper, we describe the first total synthesis of plusbacin A3 and assign the stereochemistry for the remaining unassigned lactone stereocenter. Copyright

Synthetic Route of 246047-72-3, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, molecular formula is C46H65Cl2N2PRu. In a patent, introducing its new discovery.

A photoactivated ruthenium(II) arene complex has been conjugated to two receptor-binding peptides, a dicarba analogue of octreotide and the Arg-Gly-Asp (RGD) tripeptide. These peptides can act as “tumor-targeting devices” since their receptors are overexpressed on the membranes of tumor cells. Both ruthenium-peptide conjugates are stable in aqueous solution in the dark, but upon irradiation with visible light, the pyridyl-derivatized peptides were selectively photodissociated from the ruthenium complex, as inferred by UV-vis and NMR spectroscopy. Importantly, the reactive aqua species generated from the conjugates, [(eta6-p-cym)Ru(bpm)(H2O)]2+, reacted with the model DNA nucleobase 9-ethylguanine as well as with guanines of two DNA sequences, 5?dCATGGCT and 5?dAGCCATG. Interestingly, when irradiation was performed in the presence of the oligonucleotides, a new ruthenium adduct involving both guanines was formed as a consequence of the photodriven loss of p-cymene from the two monofunctional adducts. The release of the arene ligand and the formation of a ruthenated product with a multidentate binding mode might have important implications for the biological activity of such photoactivated ruthenium(II) arene complexes. Finally, photoreactions with the peptide-oligonucleotide hybrid, Phac-His-Gly-Met-linker-p5?dCATGGCT, also led to arene release and to guanine adducts, including a GG chelate. The lack of interaction with the peptide fragment confirms the preference of such organometallic ruthenium(II) complexes for guanine over other potential biological ligands, such as histidine or methionine amino acids.

Two distinct routes to beta-cycloalkylalanine derivatives have been developed. The first route employs the reaction of the iodoalanine-derived zinc-copper reagent 2 with cycloalk-l-en-3-yl phosphates, and the second uses the palladium-catalysed coupling of the iodoalanine-derived zinc reagent 1 with cycloalkenyl triflates; in each case, catalytic hydrogenation of the unsaturated product leads to the protected beta-cycloalkylalanine. The latter route allows access to a range of cycloalkyl derivatives, with ring sizes of 5-8. beta-(1-Methyl-1-cyclohexyl)alanine may be prepared using reaction of the zinc-copper reagent 2 with 3-methyl-2-cyclohexenyl chloride, followed by hydrogenation. The corresponding cyclopentyl derivative may be prepared by reaction of the same zinc-copper reagent 2 with diethyl geranylphosphate, followed by ring-closing metathesis and hydrogenation.
