Flavonoid glycosides and isoquinolinone alkaloids from Corydalis bungeana

The whole plant of Corydalis bungeana (Papaveraceae) yielded several flavonol O-glycosides together with two isoquinolinone alkaloids. Two flavonol O-glycosides identified as the 3-O-alpha-arabinopyranosyl(1? ? 6?)-beta-glucopyranoside 7-O-beta-glucopyranosides of kaempferol and quercetin were isolated from the whole plant of Corydalis bungeana Turcz. together with eight known flavonol O-glycosides. Two isoquinolinone alkaloids were also obtained from the same source, including the new derivative, 6,7-methylenedioxy-2-(6-acetyl-2,3-methylenedioxybenzyl)-1(2H)-isoquinolinone. The structures were determined by spectroscopic methods (NMR and high-resolution MS).

Distrubution and excretion of protopine in rats by RP-HPLC method

AIM: To study the distrubution and excretion of protopine in rats. METHODS: Reversed phase high performance liquid chromatographic method (RP-HPLC) was developed for determining the level of protopine in rats. The analytical column were packed with 5 mum C18. The mobile phase was a mixture of methanol, water and 10% acetic acid (80: 20: 2), in which the pH was modulated to 5.6 with 15% ammonia. Protopine biological samples were isolated well, in which two extraction with ether under basical condition and an extraction with 0.02 mol ¡¤ L-1 sulfuric acid were performed, respectively. The content of protopine in the biological sample was measured by an UV detector at 285 nm. The distrubution and excetion of protopine have been investigated in rats after intravenous administration 10 mg ¡¤ kg-1. RESULTS: Protopine distrubuted in many tissues after iv a dose of 10 mg ¡¤ kg-1. The higher level of protopine was found in lung, kidney, spleen and brain, and the highest was observed in lung at 5, 15 minutes after administration. However the top level tissue was testicle at 3 h, which may be due to small blood circulation. The excretion of the parent compound in urine was 36.87% of dose, but the excretion of the parent compound in feces and bile was less than 1% of dose. Plasma protein binding was less than 5%. CONCLUSION: The distrubution of protopine is extensive and the parent compoud was mainly excreted by urine and plasma protein binding was low.

pi-extended anthracenes as sensitive probes for mechanical stress

Smart molecular systems having the ability to report on mechanical strain or failure in polymers via alteration of their optical properties are of great interest in materials science. However, only limited attention has been devoted to targeted chromophore engineering to fine-tune their physicochemical properties. Here, we describe the synthesis of pi-extended anthracenes that can be released from their respective maleimide Diels-Alder adducts through the application of mechanical stress in solution and in the solid state. We demonstrate the improvement of fluorescence quantum yield as well as the tuning of excitation and emission wavelengths while retaining their excellent mechanochemical properties laying the foundation for a new series of mechanophores whose spectral characteristics can be modularly adjusted.

ALKALOIDS FROM Papaver atlanticum BALL AND Papaver glaucum BOISS. et HAUSKN.

In addition to the alkaloids previously found in the aerial part of P. atlanticum BALL, viz. protopine, rhoeadine (predominant constituents), rhoeagenine, stylopine, cryptopine, sanguinarine, magnoflorine and papaverrubines A, B, E and D, we have now isolated the tertiary bases isothebaine, scoulerine, corytuberine and a new quaternary alkaloid 13beta-hydroxy-N-methylstylopinium hydroxide (I). The presence of papaverrubine B and muramine was also detected (TLC). The contents of the bases in the roots of P. atlanticum were found similar to those in the aerial part.Magnoflorine was isolated from the roots in a considerable yield.The dominant alkaloids isolated from P. glaucum BOISS. et HAUSKN. were glaudine and glaucamine; they were accompanied by protopine, papaverrubine B and traces of sanguinarine, coptisine and papaverrubine C.Magnoflorine and corytuberine have been isolated from this species for the first time and the presence of allocryptopine, cryptopine, corydine, isocorydine and papaverrubines D and H has been demonstrated.

Mechanophore activation at heterointerfaces

Silica nanoparticles grafted with poly(methyl acrylate) (PMA) chains anchored by a maleimide-anthracene cycloadduct were synthesized to demonstrate mechanochemically selective activation of mechanophores at heterogeneous interfaces. By quantifying the anthracene-containing cleaved PMA polymers, which are generated via retro-[4 + 2] cycloaddition reactions, the first-order kinetic coefficient was determined. Activation characteristics of mechanophores anchored to a nanoparticle exhibit behavior similar to mechanophore-linked polymers, e.g., threshold molecular weight and linear increase in rate coefficient with molecular weight above the threshold. This model system is thus valuable as a probe to test stress activation of interfacially bonded mechanophores relevant to the design of fiber-reinforced polymer composites.

Cycloaddition of nitrile oxides to cyclic and acyclic alpha,beta-unsaturated amides. Frontier orbital interactions and an unexpected steric drift determine regiochemistry

The regiochemistry of the cycloadditions of nitrile oxides to alpha,beta- unsaturated amides is determined by frontier orbital interactions and by a regiochemical drift due to steric effects. Cycloadditions to alpha,beta- unsaturated lactames afford mainly 4-carboxamido-isoxazolines with high regioselectivity. In cycloadditions to acyclic alpha,beta-unsaturated amides the regioselectivity relaxes and finally reverses in the case of N,N- disubstituted derivatives, because of the increasing steric congestion at the amine nitrogen.
