  Synthesis of 3,3′-(1-piperidino)substituted methylene-bis-isoxazoles preventing stimulus-induced leukocytes activation

  摘要：

  Some 3,3'-(1-piperidino)substituted methylene-bis-isoxazoles were prepared via Mannich base and tested to verify their antiinflammatory-related activity. Human neutrophils stimulated with either PMA and f-MLP were used as the cellular model. The efficiency of eight differently substituted compounds (2-9) was established on their capacity to reduce the O(2)(-) production by activated human neutrophils. The rising hydrophobicity in the side-chain of methylene-bis-isoxazoles leads to a distinction in the neutrophil response against the two stimuli, favoring the inhibition of the PMA elicited cell activation and leaving inaffected the f-MLP induced cell responses. Compounds 8 and 9 are particularly active and abolish almost completely the neutrophil activation in the presence of PMA stimulus.

  Syntheses and Evaluation of 2- or 3-(<i>N</i>-Cyclicamino)chromone Derivatives as Monoamine Oxidase Inhibitors

  摘要：

  A series of 2-(N-cyclicamino)chromone derivatives (1a-4c) and 3-(N-cyclicamino)chromone derivatives (5a-8c) were synthesized, and their monoamine oxidase (MAO) A and B inhibitory activities were studied as part of a structure-activity relationship investigation. Compounds 1a-4c showed no remarkable inhibition for MAO-A or MAO-B, whereas compounds 5a-8c (with a few exceptions) showed significant and selective inhibition of MAO-B. Of these compounds, 7c,7-methoxy-3-(4-phenyl-1-piperazinyl)-4H-1-benzopyran-4-one inhibited MAO-B the most potently and selectively, having IC50 of 15 nM and an MAO-B selectivity index of more than 6700; c.f, 50 nM and 2000, respectively, for safinamide. The mode of inhibition of 7c to MAO-B was competitive and reversible. Considering the IC50 values and selectivity indices of the other synthetic compounds, the presence of the methoxy group on the chromone ring (R-2) of 7c seemed to increase MAO-B inhibition. Molecular docking analysis also supports this hypothesis. Our results suggest that 3-(N-cyclicamino)chromones are useful lead compounds for the development of MAO-B inhibitors.

• Inhibition of neutrophil O2− production by unsymmetrical methylene derivatives of benzopyrans: their use as potential antiinflammatory agents
  作者：Mauro Mazzei、Ramona Dondero、Enzo Sottofattori、Edon Melloni、Roberto Minafra

  日期：2001.12

  Some unsymmetrical derivatives of benzopyrans 9 were synthesized and tested to verify their PKC inhibitory activity. For this purpose, the Mannich bases of 7-hydroxycoumarins 6 were treated with 2-(dialkylamino)benzopyran-4-ones or 3-(dialkylamino)naphtho[2,1-b]pyran-1-ones 8 in the presence of acetic or propionic anhydride, yielding compounds 9. Human neutrophils stimulated with either PMA and f-MLF

  日期：2001.3

  The formation of methylene-bis derivatives of benzopyran-4-ones from their Mannich bases was studied. On these grounds, unsymmetrical methylene derivatives have been synthesized by reacting Mannich bases of benzopyran-4-ones with structurally related compounds lacking the dialkylaminomethyl group.

• Synthesis of new 3,5-disubstituted isoxazoles with specific anti-group B rhinovirus activity in vitro
  作者：M Mazzei、A Balbi、E Sottofattori、R Garzoglio、A De Montis、S Corrias、P La Colla

  DOI：10.1016/0223-5234(93)90025-a

  日期：1993.1

  3,5-Disubstituted isoxazoles 4a-f were synthesized as potential anti-rhinovirus agents. These compounds were prepared in good yield by treatment of the corresponding 2-(dialkylamino)chromones 3a-f with hydroxylamine. Compounds 4 were demethylated to obtain dihydroxyderivatives 5, which were then transformed in acetyl-6 and alkylderivatives 7. The methylenbisderivatives 9 were obtained by reaction of bischromones 8 with hydroxylamine. Most compounds were subjected to antiviral screening. Compounds 4c, 7a, 7b and 7c were found to be specific inhibitors of group B rhinoviruses.
