生物活性

KKL-40 is a small molecule inhibitor that targets the trans-transcription process and is effective against methicillin-sensitive and -resistant Staphylococcus aureus (S. aureus) as well as other Gram-positive pathogens including vancomycin-resistant Enterococcus faecium, Bacillus subtilis, and Streptococcus pyogenes. KKL-40 synergizes with the human antimicrobial peptide LL-37 to inhibit S. aureus, but does not synergize with other antibiotics such as daptomycin, kanamycin, or erythromycin. Trans-transcription is an extreme form of recoding, and KKL-40 inhibits trans-transcription but is nontoxic to HeLa cells[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
