title: Toward the discovery of new antifungal agents: the design and validation of a novel 2'P-RNA probe and high throughput screening assay against 2'-phosphotransferase Tpt1p.
abstract: We report the solid-phase synthesis of novel 2'P-RNA probes for use in fluorescence polarization (FP) ligand binding assays that screens for inhibitors of the yeast 2'- phosphotransferase Tpt1p. The probe was synthesized by utilizing silyl phosphoramidite chemistry and a phosphoramidite synthon containing an orthogonal (DMT) protecting group at its 2'-position. Regioselective removal of the 2'-DMT group and phosphitylation of the unmasked 2'-hydroxyl group afforded the desired 2'P-RNA sequence.
