(EN) Disclosed are novel methods, combinations of agents and kits for use in killing, or inhibiting the growth of microorganisms. Enhanced antimicrobial action is provided by using a methylation inhibitor, as exemplified by using an agent that inhibits methylation or maturation of bacterial RNA in combination with, e.g., a macrolide lincosamide streptogramin B (MLS) antibiotic. The methods and compositions described may be employed to reduce the resistance of susceptible microorganisms to antimicrobial agents and thus to treat animals or patients with infections.(FR) Cette invention concerne de nouveaux procédés, de nouvelles combinaisons d'agents et de nouvelles trousses pour tuer les micro-organismes ou inhiber leur croissance. Le recours à un inhibiteur de méthylation, plus précisément à un agent inhibiteur de méthylation ou de la maturation d'ARN bactérien en combinaison avec, par exemple, un antibiotique à base de streptogramine B macrolide lincosamide (MLS), permet d'accroître l'activité anti-microbienne. Les procédés et les compositions faisant l'objet de cette invention peuvent être employés pour diminuer la résistance aux agents anti-microbiens de micro-organismes sensibles, et pour traiter ainsi les animaux ou les patients souffrant d'infections.
Synthesis and evaluation of analogues of S-adenosyl-l-methionine, as inhibitors of the E. coli cyclopropane fatty acid synthase
synthesized and evaluated as inhibitors of the purified E. coli cyclopropane fatty acid synthase, a model for M. tuberculosis cyclopropane synthases that are potential targets for antituberculous drugs. Our results show that the presence of the adenosine moiety, in the inhibitor, is required for strong binding, but that the sulfonium charge is less important. The best inhibitors found were S-adenosyl-l-homocysteine

center of SAHO, with a preference for S–C(5′) bond cleavage. Similar S–C cleavage activity was also found for SHAO2, but no S–O cleavage was observed. In contrast to NosL, NosN almost exclusively cleaves the S–C(5′) bonds of SAHO and SAHO2 with much higher efficiencies. Our study provides valuable insights into the [4Fe-4S] cluster-mediated reduction reactions and highlights the remarkable catalytic
