Our first generation of hydroxyethylamine BACE-1 inhibitors proved unlikely to provide molecules that would lower amyloid in an animal model at low oral doses. This observation led us to the discovery of a second generation of inhibitors having nanomolar activity in a cell-based assay and with the potential for improved pharmacokinetic profiles. In this Letter, we describe our successful strategy for the optimization of oral bioavailability and also give insights into the design of compounds with the potential for improved brain penetration.

Page/Page column 18, (2010/02/12)
The present invention relates to novel hydroxyethylamine compounds having Asp2 (β-secretase, BACE1 or Memapsin) inhibitory activity of formula (I), processes for their preparation, to compositions containing them and to their use in the treatment of diseases characterised by elevated β-amyloid levels or β-amyloid deposits, particularly Alzheimer's disease. Formula (I) wherein, inter alia, A-B represents -NR5-SO2- or -NR5-CO-; R5 represents hydrogen, C1-6alkyl, C3-6 alkenyl, C3-6 alkynyl, C3-10 cycloalkyl, -C0-6 alkylaryl, -C0-6 alkyl-heteroaryl, -C0-6 alkyl-heterocyclyl, -C3-10 cycloalkyl-aryl or -C3-10 cycloalkyl-heteroaryl; -W- represents -CH2-, -(CH2)2-, -(CH2)3-, -C(H)=C(H)- or -CH2-C(H)=C(H)-; X-Y-Z represents -C=CR8-NR9-;

10-Methoxycarbonyl-1H-pyrrolophenanthridine was obtained by the cyclization of 4-(2-chlorobenzylideneamino)-6-methoxycarbonylindole by the action of sodium amide in liquid ammonia.Its physicochemical characteristics were studied.
