A novel prodrug of an impermeant inhibitor of 3-deoxy-D-manno-2-octulosonate cytidylyltransferase has antibacterial activity
摘要:
Although 8-amino-2,6-anhydro-3,8-dideoxy-D-glycero-D-talo-octonic acid (2) is a potent inhibitor of 3-deoxy-D-manno-octulosonate cytidylyltransferase (CMP-KDO synthetase), it is unable to reach its cytoplasmic target and is therefore inactive as an antibacterial agent. However, esterification of 2 with 8-(hydroxymethyl)-1-naphthyl methyl disulfide (8) generates a prodrug (12), which gains entry into bacterial cells. Intracellular reduction of the disulfide leads to a rapid, intramolecular, displacement of the acid 2, which then inhibits the growth of Gram-negative bacteria by interfering with the biosynthesis of lipopolysaccharide.
