Antisense antibacterial method and compound

摘要

A method and antisense compound for inhibiting the growth of pathogenic bacterial cells are disclosed. The compound contains no more than 12 nucleotide bases and has a targeting nucleic acid sequence of no fewer than 10 bases in length that is complementary to a target sequence containing or within 10 bases, in a downstream direction, of the translational start codon of a bacterial mRNA that encodes a bacterial protein essential for bacterial replication. The compound binds to a target mRNA with a T of between 50 °C to 60 °C. The relatively short antisense compound are substantially more active than conventional antisense compounds having a targeting base sequence of 15 or more bases.
