2-C-methyluridine modified hammerhead ribozyme against the estrogen receptor. Bioorg Med Chem Lett 2010; 20:2806-8. [PMID: 20362443 DOI: 10.1016/j.bmcl.2010.03.060] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2010] [Revised: 03/09/2010] [Accepted: 03/11/2010] [Indexed: 11/20/2022]
Abstract
A new synthesis of 2'-C-methyluridine phosphoramidite is presented. Special emphasis is dedicated to the improvement of the protection of the tertiary 2'-hydroxyl group. Comparison to previous protecting strategies and analysis of stability under 5'-DMTr removing conditions are discussed. The synthetic incorporation of this modified nucleoside into the catalytic core of a hammerhead ribozyme against the estrogen receptor alpha protein (ER-alpha), and transfection experiments in MCF-7 cell line are also presented.
