Chemical Synthesis and Properties of 5-Taurinomethyluridine and 5-Taurinomethyl-2-thiouridine
摘要:
Unique taurine-containing Uridine derivatives, 5-taurinomethyluridine (tau m(5)U) and 5-taurinomethyl-2-thiouridine (tau m(5)s(2)U), which were discovered in mammalian mitochondrial tRNAs, exist at the first position of the anticodon. In this paper, we report the first efficient synthesis of tau m(5)U and tau m(5)s(2)U and describe their physicochemical properties. These modified ribonucleosides were synthesized by the reaction of 5-substituted uridine derivatives with a tetrabutylammonium salt of taurine that is highly reactive and well-soluble in common organic solvents. UV and H-1 NMR spectrometric studies revealed the structural properties of the taurine-containing base moieties and the Sugar conformations of these modified ribonucleosides.
