Solid-phase synthesis and antibacterial activity of hydroxycinnamic acid amides and analogues against methicillin-resistant Staphylococcus aureus and vancomycin-resistant S. aureus
A library of hydroxycinnamic acid amides (HCAAs) and analogues were synthesized using solid-phase synthesis technique. These compounds were screened for antibacterial against methicillin-resistant Staphylococcus aureus (MRSA) (11 strains) and vancomycin-resistant S. aureus (VRSA) (4 strains). Dihydrocaffeoyl analogues showed activity against VRSA which were better than the reference drugs, vancomycin and oxacillin. These compounds also exhibited antibacterial activity against MRSA, which were more potent than oxacillin. (c) 2006 Elsevier Ltd. All rights reserved.

(EN) The invention relates to compositions capable of influencing the development and the flowering of plants. These compositions are caracterized in that they are comprised of at least one amine appropriate to conjugate $i(in situ) with a phenol, particularly with a hydroxycinnamic acid, associated with an appropriate treatment vehicle. Applications to the production of modified plants.(FR) La demande est relative à des compositions propres à influencer le développement et la floraison de plantes. Ces compositions se caractérisent en ce qu'elles comprennent au moins une amine propre à se conjuguer $i(in situ) avec un phénol, notamment avec un acide hydroxicinamique, associée à un véhicule de traitement approprié. Applications à l'obtention de plantes modifiées.

Bioassay guided fractionation from corn gluten meal, a byproduct of a starch manufacturing plant, gave N-p-coumaroyl-N'-feruloylputrescine (1) and N,N'-diferuloylputrescine (2) as alpha-glucosidase inhibitors. Some structure-activityrelationships were studied by comparing the inhibitory activity by preparing some related compounds, and it was revealed that the hydroxyl group was important for the
