Design, synthesis, and electrophysiological evaluation of NS6740 derivatives: Exploration of the structure-activity relationship for alpha7 nicotinic acetylcholine receptor silent activation

The α7 nicotinic acetylcholine receptor (nAChR) silent agonists, able to induce receptor desensitization and promote the α7 metabotropic function, are emerging as new promising therapeutic anti-inflammatory agents. Herein, we report the structure–activity

Synthesis of novel derivatives of (1S,4S)-2,5-diazabicyclo[2.2.1]heptane and their evaluation as potential ligands in asymmetric catalysis

Thirty-seven (most of them novel) chiral derivatives of (1S,4S)-2,5-diazabicyclo[2.2.1]heptane (2-36, 38, 39) were prepared from (S)-trans-4-hydroxyproline. A selection of these chiral ligands were examined as potential ligands in the preparation of catalysts for the enantioselective addition of diethylzinc to aldehydes and as chiral Lewis acid activators in the asymmetric Diels-Alder reaction. In the former system, diamine 30 induced up to 92 % enantiomeric excess in the formation of (S)-phenyl ethyl carbinol, whereas in the case of the cycloaddition reaction between cyclopentadiene and 3-acryloyloxazolidin-2-one the catalytic complex formed between dimeric derivative 8 and copper triflate [Cu(OTf)2] afforded the expected product in a 95:5 endo/exo ratio and up to 72 % ee for the major diastereomeric product. Finally, some of the novel chiral diamines prepared in this work were also evaluated as potential organocatalysts in the asymmetric amination of ethyl α-phenyl-α-cyano acetate. Bifunctional derivative 12 provided the animated product in excellent yield and with up to 40 % ee. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.

Trans-4-aminoproline, a phytotoxic metabolite with herbicidal activity produced by Ascochyta caulina

A phytotoxic metabolite, characterized through NMR techniques and synthetic methods as trans-4-aminoproline, was isolated from the culture filtrates of Ascochyta caulina, a promising mycoherbicide for biological control of Chenopodium album. The metabolite, which shows interesting phytotoxic properties, together with ascaulitoxin (recently characterized as N2-β-D-glucoside of the unusual bis-amino acid 2,4,7-triamino-5- hydroxyoctandioc acid) and another unidentified compound, compose an active fraction of A. caulina culture filtrates with promising herbicidal properties. When assayed on leaves of host and non host dicots, including wild and cultivated plants, the trans-4-aminoproline showed a wide range of toxicity, with leaves of C. album being the most sensitive. Other interesting aspects were its inefficacy on several monocots, both cultivated and wild, and its lack of antifungal, antibiotic and zootoxic activities. This is the first report on trans-4-aminoproline as naturally occurring compound and phytotoxic metabolite produced by A. caulina. (C) 2000 Elsevier Science Ltd.
