A new drug design targeting the adenosinergic system for Huntington's disease.

ABSTRACT:

Background

Huntington's disease (HD) is a neurodegenerative disease caused by a CAG trinucleotide expansion in the Huntingtin (Htt) gene. The expanded CAG repeats are translated into polyglutamine (polyQ), causing aberrant functions as well as aggregate formation of mutant Htt. Effective treatments for HD are yet to be developed.

Methodology/principal findings

Here, we report a novel dual-function compound, N(6)-(4-hydroxybenzyl)adenine riboside (designated T1-11) which activates the A(2A)R and a major adenosine transporter (ENT1). T1-11 was originally isolated from a Chinese medicinal herb. Molecular modeling analyses showed that T1-11 binds to the adenosine pockets of the A(2A)R and ENT1. Introduction of T1-11 into the striatum significantly enhanced the level of striatal
