The 4-acetamidopyrrole-2-carboxylate is reported to be the true precursor of congocidine in Streptomyces. A biosynthetic pathway is proposed starting with N-acetylglucosamine-1-phosphate, involves carbohydrate metabolizing enzymes and differs from known pyrrole biosynthetic pathways. In the experiment, the researchers used many compounds, for example, Ethyl 4-nitro-1H-pyrrole-2-carboxylate (cas: 5930-92-7Category: esters-buliding-blocks).
Ethyl 4-nitro-1H-pyrrole-2-carboxylate (cas: 5930-92-7) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Category: esters-buliding-blocks
