The Synthesis and Biological Activity of 1-(2-Deoxy-4-Thio-α;-L-Threo-Pentofuranosyl)Thymine
摘要:
The procedure of Huang and Hui (Nucleosides & Nucleotides 1993, 12, 139-147) was found to give benzyl 3,5-di-O-benzyl-2-deoxy-1,4-dithio-alpha-L-threo-pentofuranoside (6) rather than the claimed D-erythro isomer. This sugar was converted to an anomeric mixture of the thymine nucleosides. The mixture was separated and the alpha-anomer (alpha-10) was found to be cytotoxic, whereas the beta-anomer (beta-10) was inactive.
