Descripción general

Chemical structure: coumarin-glycoside

Aplicación

Coumermycin A1 is an aminocoumarin antibiotic used to study processes such as DNA replication, transcription, and recombination that involve DNA topoisomerase II activity. It has been used to treat Staphylococcus aureus endocarditis in the rat model and to study the effect of coumermycin A1 on the expression of 67 fusions in Salmonella typhimurium. .

Acciones bioquímicas o fisiológicas

Coumermycin A1 inhibits DNA Gyrase which thereby inhibits cell division in bacteria.

We have estimated the extent to which relaxation of supercoiling by the DNA gyrase inhibitor coumermycin A1 affects gene expression in vivo in Salmonella typhimurium. We isolated a set of Mu d1-8 Lac+ operon fusions to random promoters and measured

[structure: see text] The coumarin antibiotics are not only potent inhibitors of DNA gyrase but also represent the most effective C-terminal inhibitors of 90 kDa heat shock proteins (Hsp90) reported thus far. In contrast to the N-terminal ATP-binding site, little

Heat shock protein 90 (HSP90) regulates multiple signalling pathways critical for tumour growth. As such, HSP90 inhibitors have been shown to act as effective anticancer agents in preclinical studies but, for a number of reasons, the same effect has not

The efficacy of a 5-day treatment with coumermycin A1 (hereafter referred to as coumermycin) (at three dosage regimens), with ciprofloxacin, or with coumermycin plus ciprofloxacin was tested in experimental aortic valve endocarditis induced in rats by a strain of methicillin-susceptible

The aminocoumarin antibiotics novobiocin, clorobiocin and coumermycin A(1) are formed by different Streptomyces strains and are potent inhibitors of bacterial gyrase. Their biosynthetic gene clusters have been analyzed in detail by genetic and biochemical investigations. Heterologous expression of these gene
