General description

SQ109 is a 1,2-ethylenediamine, which is related to ethambutol.

Application

SQ109 has been used:
  • as an antitubercular agent to study its interactions with mycobacterial membrane proteins large 3 (MmpL3) binding pocket
  • as a positive control to determine the minimum inhibitory concentration (MIC) of ohmyungsamycins (OMS) A and B against Mycobacterium tuberculosis (Mtb) using the resazurin microtiter assay (REMA) plate method
  • as an inhibitor of MmpL3 to explore the utility of mycobacterial CRISPR interference for validating target gene essentiality and compound mode of action

Biochem/physiol Actions

SQ109 exhibits activity against Helicobacter pylori and the fungi Candida albicans. It might also possess anti-bacterial activity.
SQ109 is an antitubercular developed for the treatment of multidrug-resistant tuberculosis (MDR-TB). SQ109 inhibits the activity of MmpL3, a mycolic acid transporter required for incorporation of mycolic acid into the Mycobacterium tuberculosis cell wall.

There is an urgent need for novel therapeutics to treat Mycobacterium tuberculosis infections. Genetic strategies for validating novel targets are available, yet their time-consuming nature limits their utility. Here, using MmpL3 as a model target, we report on the application

The Mycobacterium tuberculosis protein MmpL3 performs an essential role in cell wall synthesis, since it effects the transport of trehalose monomycolates across the inner membrane. Numerous structurally diverse pharmacophores have been identified as inhibitors of MmpL3 largely based on the

SQ109, a 1,2-diamine related to ethambutol, is currently in clinical trials for the treatment of tuberculosis, but its mode of action remains unclear. Here, we demonstrate that SQ109 disrupts cell wall assembly, as evidenced by macromolecular incorporation assays and ultrastructural
