Bidentate Lewis Acid Catalyzed Domino Diels-Alder Reaction of Phthalazine for the Synthesis of Bridged Oligocyclic Tetrahydronaphthalenes

A domino process consisting of an inverse and a normal electron-demand Diels-Alder reaction is presented for the formation of bridged tri- and tetracyclic 1,2,3,4-tetrahydronaphthalenes catalyzed by a bidentate Lewis acid. The products were synthesized in a one-pot reaction from commercially available starting materials and contain up to six stereogenic centers. The tetrahydronaphthalenes were isolated as single diastereomers and are derivatives of phenylethylamine, which is well-known as a scaffold of amphetamine or dopamine.

Structure-Function Characteristics and Signaling Properties of Lipidated Peptidomimetic FPR2 Agonists: Peptoid Stereochemistry and Residues in the Vicinity of the Headgroup Affect Function

Formyl peptide receptor 2 (FPR2) plays important roles in inflammation. In the present study, 20 analogues of the FPR2-selective lipidated alpha-peptide/beta-peptoid agonist Lau-[(S)-Aoc]-[Lys-betaNPhe]6-NH2 were generated, which allowed two novel subclasses of more potent FPR2 agonists to be distinguished. Critical factors influencing FPR2 recognition comprise the presence of beta-peptoid phenylalanine-like residues (i.e., betaNPhe, betaNspe, or betaNrpe) in the peptidomimetic tail, configuration of the 2-Aminooctanoic acid (Aoc) in the headgroup, and the length of the N-Terminal fatty acid. Intriguingly, a single betaNrpe residue in the vicinity of the N-Terminus (i.e., Lau-[(S)-Aoc]-Lys-betaNrpe-[Lys-betaNPhe]5-NH2) proved to increase the agonist potency, whereas the betaNspe-containing analogue was a weak FPR2-selective antagonist. Another subclass displaying potent agonism comprised analogues possessing two alpha-Amino acids vicinal to the headgroup. The optimized FPR2-Activating lipidated peptidomimetics exhibited biased signaling: PLC-PIP2-Ca2+ signaling was activated, but without recruitment of beta-Arrestin or induction of chemotaxis. These FPR2-interacting compounds are considered to be useful tools in future studies of receptor-ligand interactions.

Adsorbate Photochemistry on a Colloid Surface: Phthalazine on Silver

Phthalazine adsorbed on colloidal silver surfaces is found to convert photochemically to a product in which the N=N bond of the molecule likely breaks to form an adsorbed species resembling an ortho-substituted benzene.The photochemical kinetics was studied using a simple flow cell.The photochemical rate constant was found to be large in the visible region of the spectrum, increasing toward the blue.We show, incidentally, that SERS spectra of phthalazine reported previously by us and by others were heavily contaminated by the spectral features of the photoproduct.Hence previous explanations of the unusual excitation wavelength and coverage dependence are incorrect.The photochemical reaction is found to be a one-photon process; hence, the large absorption cross section in the visible is likely due to a metal to molecule charge transfer transition. (Solution-phase phthalazine is transparent in the visible.) It is likely that a significant number of published SERS spectra of other molecules contain spectral features due to photoproducts.By using dynamic methods such as that described, one can avoid these complications.

Naturally appearing N-feruloylserotonin isomers suppress oxidative burst of human neutrophils at the protein kinase C level

N-feruloylserotonin (N-f-5HT) isomers, isolated from seeds of Leuzea carthamoides (Wild) DC, inhibited dose-dependent oxidative burst in human whole blood and isolated neutrophils in vitro, which were measured by luminol- and/or isoluminol-enhanced chemiluminescence in the following rank order of stimuli: PMA > OpZ > calcium ionophore A23187. In isolated neutrophils that were stimulated with PMA, N-f-5HT isomers were effective against extracellular and intracellular reactive oxygen species. Liberation of ATP, analysis of apoptosis, and recombinant caspase-3 activity revealed that N-f-5HT isomers, used in concentrations up to 100 muM, did not alter the viability and integrity of isolated neutrophils. Western blot analysis documented that in concentrations of 10 and 100 muM, N-f-5HT isomers significantly decreased PMA-induced phosphorylation of PKC alpha/beta II. The results suggest that N-f-5HT isomers are an effective, naturally occurring substance with a potent pharmacological effect on the oxidative burst of human neutrophils. It should be further investigated for its pharmacological activity against oxidative stress in ischemia-reperfusion, inflammation and other pathological conditions. Copyright

Coumarin substituted pyrrolo-fused heterocyclic systems by 1,3-dipolar cycloadditon reactions

A variety of new pyrrolo-fused heterocyclic systems bearing a 3-carbonylchromen-2-one moiety on the pyrrole rings was obtained based on 1,3-dipolar cycloaddition reactions of corresponding cycloimmonium-ylides, generated in situ from the quaternary salts of several N-heterocycles with 3-(2-bromoacetyl)-2H-chromen-2-one, with electron-deficient alkynes. The synthetic strategies were both one-pot, three-component and classical multistep 1,3-dipolar cycloaddition reactions. The all newly synthesized compounds were structurally characterized by elemental analysis, IR and NMR spectroscopy. Graphical abstract: [Figure not available: see fulltext.]

Investigation on the photoreactions of nitrate and nitrite ions with selected azaarenes in water

The photoreactions of selected azaarenes with nitrate and nitrite ions were investigated under irradiation at lambda = 313 nm. The excitation of both anions leads to several photochemical reactions forming mainly hydroxyl radicals and nitrogen oxides. The purification capability of natural waters i.e. the oxidation of inorganic and organic substances results from the formation of hydroxyl radicals. Nitrated isomers of azaarenes were found among the main products of the investigated photoreactions. The nitrogen oxides were responsible for the production of nitrated derivatives which possess a high toxic potential. Their formation was explained by the parallel occurance of two mechanism, a molecular and a radical one. The molecular mechanism became more important with increasing ionisation potentials of the azaarenes. The spectrum of oxidized products corresponded to the one got in the photoreactions of azaarenes with hydrogen peroxide. The formation of several oxidation and nitration products of the pyridine ring with its low electron density was explained by the reaction of excited states of azaarenes. The photoreactions with nitrite ions only led to the formation of oxidized and nitrated products. Nitroso products were not formed. The reactivity of nitrogen monoxide is too low for its reaction with the azaarenes.
