coumarin catabolic process

Definition

Target type: biologicalprocess

The chemical reactions and pathways resulting in the breakdown of coumarins, compounds derived from the phenylacrylic skeleton of cinnamic acids. [GOC:ai]

Coumarin catabolism is a complex metabolic pathway involving the degradation of coumarin, a naturally occurring compound found in plants. The process begins with the hydroxylation of coumarin by the enzyme coumarin 7-hydroxylase, producing 7-hydroxycoumarin. This step is crucial for the detoxification of coumarin, as it increases its water solubility and facilitates its excretion. Subsequent steps involve the oxidation of 7-hydroxycoumarin to 3,4-dihydrocoumarin, followed by its cleavage to o-coumaric acid. This acid can then be further metabolized through various pathways, including conjugation with glucuronic acid or sulfate, or degradation to other compounds. Coumarin catabolism plays a significant role in the detoxification and elimination of coumarin from the body, preventing its accumulation and potential toxicity. The specific enzymes and pathways involved in coumarin catabolism may vary depending on the species and the specific coumarin compound being metabolized.'

acetazolamideAcetazolamide: One of the CARBONIC ANHYDRASE INHIBITORS that is sometimes effective against absence seizures. It is sometimes useful also as an adjunct in the treatment of tonic-clonic, myoclonic, and atonic seizures, particularly in women whose seizures occur or are exacerbated at specific times in the menstrual cycle. However, its usefulness is transient often because of rapid development of tolerance. Its antiepileptic effect may be due to its inhibitory effect on brain carbonic anhydrase, which leads to an increased transneuronal chloride gradient, increased chloride current, and increased inhibition.
