d-Alanine-d-alanine ligase (DDl) is an essential enzyme in bacterial cell wall biosynthesis and an important target for developing new antibiotics. Here, we describe a new approach to identify new inhibitor scaffolds for DDl based on similarity in the ATP

For the alternating copolymerization of CO2 and cyclohexene oxide, a variety of zinc acetate complexes with new aminoimidoacrylate ligands has been synthesized and tested as catalysts. All complexes catalyzed the reaction and structure-activity
Alternating copolymerization of cyclohexene oxide and CO2 catalyzed by zinc complexes with new 3-amino-2-cyanoimidoacrylate ligands

New 3-amino-2-cyanoimidoacrylate ligands with varying steric demands have been synthesized. Zinc acetate complexes of these ligands catalyze the copolymerisation of CO2 and cyclohexene oxide, showing high activities (TOF up to over 200 h -1).

We have previously described a novel series of low molecular weight protein tyrosine kinase inhibitors which we named tyrphostins.The characteristic active pharmacophore of these compounds was the hydroxy-cis-benzylidenemalonitrile moiety.In this article we describe three novel groups of tyrphostins: (i) one group has the phenolic moiety of the cis-benzylidenemalononitrile replaced either with other substituted benzenes or with heteroaromatic rings, (ii) another is a series of conformationally constrained derivatives of hydroxy-cis-benzylidenemalononitriles in which the malononitrile moiety is fixed relative to the aromatic ring, and (iii) two groups of compounds in which the position trans to the benzenemalononitrile has been substituted by ketones and amides.Among the novel tyrphostins examined we found inhibitors which discriminate between the highly homologous EGF receptor kinase (HER1) and ErbB2/neu kinase (HER2).These findings may lead to selective tyrosine kinase blockers for the treatment of diseases in which ErbB2/neu is involved.
