Synthesis of 2,4,5-triaminocyclohexanecarboxylic acid as a novel 2-deoxystreptamine mimic
摘要:
Since aminoglycosides have been known to exert their antibacterial activities by binding to various RNA targets, 2-deoxystreptamine served as a particularly important model in understanding RNA-small molecule interaction. Herein, 2,4,5-triaminocyclohexanecarboxylic acid was prepared as a novel 2-deoxystreptamine (2-DOS) mimic, which replaces highly flexible glycosidic bonds of aminoglycosides with amide bonds and may improve binding selectivity toward RNA targets through increased rigidity and additional hydrogen-bonding capability. This unnatural g-amino acid can also be used as a potential component for synthetic foldamers. (C) 2010 Elsevier Ltd. All rights reserved.

In this study, a divergent and practical solid-phaseparallel diversity-oriented synthesis (DOS) strategy was successfully applied for the construction of five discrete coreskeletons embedded with privileged benzopyranyl substructure. The diversity of these coreskeletons was expanded through the introduction of various substituents at the R, R(1), and R(2) positions from a single key intermediate

The present invention provides compounds of formula I and pharmaceutical compositions for inhibiting fatty acid amide hydrolase (FAAH). Inhibition of FAAH is contemplated as a method to sustain the levels of the fatty acid ethanolamides arachidonoylethanolamide (AEA), palmitoylethanolamide (PEA), and oleoylethanolamide (OEA), three substrates of FAAH, in conditions characterized byreduced concentrations of AEA, PEA and OEA. The invention also provides methods for treating disorders in which decreased levels of AEA, PEA and OEA are associated with the disorder.
