Investigations of Novel Azomethine Ylide-Forming Photoreactions of N-Silylmethylimides

The scope of a recently discovered (Yoon, E.C. et al.J.Am.Chem.Soc. 1995, 117, 2698), azomethine ylide-forming photoreaction has been explored by probing the excited state chemistry of several N-trimethylsilylmethyl substituted cyclic and acyclic imides and amide analogs.Photolysis of N-<(trimethylsilyl)methyl>maleimide (4) in acetonitrile leads to efficient production of the tricyclic product 16, formed by trapping of the photogenerated azomethine ylide intermediate 15 through cycloaddition with 4.Irradiation 4 in solutions containing high concentrations of the dipolarophiles, acrylonitrile or fumaronitrile, results in production of the products (19-21 and 23-24, respectively) arising by cycloaddition of the ylide 15 with the added dipolarophiles.In contrast, photolysis of the nonconjugated cyclic imide, N-<(trimethylsilyl)methyl>succinimide (5), brings about N-acyl migration resulting in the exclusive production of the unstable, iminolactone 30.On the other band, acyclic, N-trimethylsilylmethyl aroyl imides 6-8 undergo the excited state C to O silyl migration reaction to produce azomethine ylide intermediates 35.Both in the presence or absence of added dipolarophiles, these ylides undergo electrocyclization to form transient aziridine intermediates 36 which react further by ring opening to generate N-phenacylamide products 32-34.In contrast, the nonconjugated imide, N-<(trimethylsilyl)methyl>-N-acetylacetamide (9), is unreactive upon irradiation.Similarly, simple N-<(trimethylsilyl)methyl>amides 10-13, while being photochemically labile, do not react to form “trappable” ylide intermediates upon irradiation.The results outlined above are presented and discussed in terms of the scope and limitations of the new, azomethine ylide-forming photoreaction of silylmethyl imides.

Characterization of aromatase binding agents from the dichloromethane extract of Corydalis yanhusuo using ultrafiltration and liquid chromatography tandem mass spectrometry

Aromatase represents an important target for the treatment of hormone-dependent breast cancer. In the present study, nine alkaloids from the dichloromethane extract of Corydalis yanhusuo were identified by liquid chromatography tandem mass spectrometry (LC-MS/MS) and tested for their aromatase binding activities using an ultrafiltration LC-MS method by investigating the differences of peak areas of compounds before and after incubations with aromatase. It was demonstrated that the quaternary protoberberine alkaloids and the tertiary protoberberine alkaloids exhibited potent aromatase binding activities. The quaternary ammonium group and the methyl group at C-13 position of tertiary protoberberine alkaloids might be necessary for the activity. The findings should provide guidance for the discovery of potential aromatase inhibitors from natural products.

Nematocidal activity of isoquinoline alkaloids against a species of Diplogastridae

We examined the nematocidal activity of various isoquinoline alkaloids. The method of evaluating nematocidal activity involved the microscopic examination of the state of larvae after the compound was administered to determine the minimum lethal concentration (MLC). In addition, cytotoxic activity (IC50) was examined using HL-60 culture cells. The compound dehydrocorydaline was found to have considerable nematocidal activity and weak cytotoxicity; its cytotoxicity value was equal to that of thiabendazole. We conclude that dehydrocorydaline, with its attractive balance between nematocidal activity and weak cytotoxicity, is the most promising of the tested compounds as a possible remedy for parasitic diseases.
