Discovery, synthesis and biochemical profiling of purine-2,6-dione derivatives as inhibitors of the human poly(A)-selective ribonuclease Caf1
摘要:
Eukaryotic mRNA contains a 3' poly(A) tail, which plays important roles in the regulation of mRNA stability and translation. Well-characterized enzymes involved in the shortening of the poly(A) tail include the multi-subunit Ccr4-Not deadenylase, which contains the Caf1 (Pop2) and Ccr4 catalytic components, and poly(A)-specific ribonuclease (PARN). Two Mg2+ ions present in the active sites of these ribonucleases are required for RNA cleavage. Here, we report the discovery, synthesis and biochemical profiling of purine-2,6-dione derivatives as (sub) micromolar inhibitors of Caf1. (C) 2015 The Authors. Published by Elsevier Ltd.

Conformational Analysis and Absolute Configuration of Axially Chiral 1-Aryl and 1,3-Bisaryl-xanthines
The xanthine scaffold is known to be the forefather of a class of biological active molecules. Xanthine is a planar framework in which an aryl substituent linked in the 1 or 3 position is driven out of the xanthine plane because of the steric hindrance exerted by the two carbonyls. This work analyses the stereodynamics of some 1-aryl and 1,3-bisaryl-xanthines and describes the steric requirements needed
