An expeditious synthesis of 6-aminophenanthridines
摘要:
A simple synthesis of biologically active 6-aminophenanthridines was achieved by a Suzuki-Miyaura coupling reaction. Condensation of 2-(4,4,5,5-tetramethyl-1,3-dioxaborolan-2-yl)aniline with 2-chlorobenzonitriles afforded 6-aminophenanthridines useful as prions inhibitors in a mild one-step procedure. The intermediate 2-amino-2'cyanobiphenyls could not be isolated. (c) 2005 Elsevier Ltd. All rights reserved.
Biologically active 6-aminophenanthridines were prepared in a single step procedure: Metal amides in liquid ammonia promoted the condensation of anilines with 2-chloro-benzonitriles. 6-Aminophenanthridines were isolated in moderate yield. (C) 2004 Elsevier Ltd. All rights reserved.

The invention concerns screening molecules with anti-prion activity. More particularly, it concerns kits for screening molecules with anti-prion activity characterized in that they comprise in combination a [PSI+], phenotype yeast, an antibiogram and an agent for purifying prions at sub-efficient doses, said yeast including the adel-14 allele of the ADE1 gene and an inactivated ERG6 gene, the screening methods, and a family of molecules with anti-prion activity isolated by the inventive screen. The invention is applicable to anti-prion agents for producing medicines in particular for treating neurodegenerative diseases involving protein aggregates.

A kit and a method for identifying compounds having anti-prion activity are provided. The kit comprises a yeast of phenotype [PSI+]; an antibiogram; and a prion curing agent in a sub-effective dose, wherein the yeast has the adel-14 allele of the ADE1 gene and an inactivated ERG6 gene. Compounds and pharmaceutical compositions having anti-prion activity are also provided, which are useful for treating various neurodegenerative diseases, including polyglutamines expansion associated diseases; Huntington's disease; Kennedy disease; amyotrophic lateral sclerosis; cerebellous autosomic ataxies; dentalorubral-pallidoluysian atrophy; and spino-bulbar amyotrophy.
