STRUCTURAL MIMETICS OF PROLINE-RICH PEPTIDES AND THE PHARMACEUTICAL USE THEREOF
-
, (2011/02/26)
The invention relates to compounds of general formula (I), which can be used particularly as structural mimetics of proline-rich peptides and are therefore capable of binding PRM binding domains (proline-rich motif binding domains) of proteins. The invention also relates to the use of said compounds as pharmaceutical active agents and the use of these pharmaceutical active agents for treating bacterial diseases, neurodegenerative diseases and tumours.

A short, practical synthesis of novel, unsymmetrical 4,5′-bis-proline compounds has been achieved, highlighted by the application of an unprecedented samarium diiodide-driven regio- and diastereocontrolled reductive dimerization of N-acyloxyiminium ions generated from readily available 2-methoxy-5- silyloxymethyl-N-Boc pyrrolidines. The title proline dimers proved to be pertinent metal-free catalysts in aldol and Mannich reactions.

The 2,5-trans-substituted oligopyrrolidines constitute a promising class of novel RNA-binding agents as well as potential building blocks for artificial anion channels. A convergent synthesis of terpyrrolidine 1 and pyrrolidino-THF-pyrrolidine 2 is reported, relying upon convergent coupling of 2,5-trans-pyrrolidinecarboxaldehydes through bridging alkyne units under Felkin-Anh control and subsequent closure of the central ring. After complete deprotection, the free polyamine products were isolated in excellent yield and purity. Crystal structure analyses of a terpyrrolidine and a pyrrolidino-THF-pyrrolidine documented their helical privileged conformations. The compounds were then screened for RNA cleavage activity. Unlike the only weakly active simple polyamines, p-nitrosulfonamide 33 was found to induce cleavage at mM concentrations under physiologically relevant conditions.
