Abstract
Cystathionine γ-lyase (CSE) is a key enzyme for the H2S generation in such pathogenic bacteria as Staphylococcus aureus, Pseudomonas aeruginosa, etc. Suppression of CSE activity significantly increases the sensitivity of bacteria to the action of antibiotics. Here, we present a method for the synthesis of a novel indole-based CSE inhibitor, 3-amino-5-[(6-bromo-1H-indol-1-yl)methyl]thiophene, named MNS1. The synthesis of this compound is based on the modification of substituted thiophene as the main structural fragment, which is involved the alkylation of 6-bromoindole at the final stages. The dissociation constant of the MNS1 complex with bacterial CSE (from S. aureus, SaCSE) was 0.5 μM, which was an order of magnitude lower than that for human CSE (hCSE). The MNS1 compound was shown to effectively enhance the antibacterial effect of gentamicin against Bacillus subtilis, allowing it to be used as an antibiotic potentiator, to inhibit the growth of CSE-expressing bacterial cells.
