Deferoxamine Drug Metabolism

Homo sapiens
Deferoxamine is a drug that is not metabolized by the human body as determined by current research and biotransformer analysis. Deferoxamine passes through the liver and is then excreted from the body mainly through the kidney.

Deflazacort Action Pathway

Homo sapiens
Deflazacort, also known as Emflaza, is a corticosteroid prodrug used to treat Duchenne muscular dystrophy (DMD). This disease is an inherited disorder resulting from mutations of the dystrophin gene, which is important for muscle function. This causes muscle weakness and progressive breathing and cardiovascular disability. Deflazacort improves various symptoms, including muscle weakness and cardiorespiratory symptoms in addition to delaying their onset. Since deflazacort is a prodrug, it is metabolized to 21-deflazacort by plasma esterases. 21-deflazacort binds to the glucocorticoid receptor to exert anti-inflammatory and immunosuppressive effects on the body. The exact mechanism by which deflazacort exerts its therapeutic effects in patients is still unclear but likely occurs via its anti-inflammatory activities. By binding to the glucocorticoid receptor, it probably influences transcription factors AP-1 and NF-kB to block the transcription of COX-2/prostaglandin G/H synthase 2 which reduces the amount of prostanoids being produced from arachidonic acid. Prostanoids such as PGI2 and thromboxane A2 influence the effects of inflammation through vasoconstriction/dilation, pain sensitivity, and platelet aggregation. 21-deflazacort could also affect the promoter of annexin-1, an important inflammatory protein as it affects leukocytes and blocks phospholipase A2 which reduces the amount of arachidonic acid being cleaved from the phospholipid bilayer. Reducing the amount of arachidonic acid formed further decreases the concentrations of prostanoids mentioned calming inflammation. Deflazacort is administered as an oral suspension or tablet.

Degradation of Superoxides

Mus musculus
Reactive oxygen species (ROS) are formed by the normal metabolic process of oxygen. Examples are superoxide, oxygen ions and peroxides and can be of either organic or inorganic origin. ROS are highly reactive due to unpaired valence shell electrons, and can cause serious damage to cells and cell organelles. The environment also may cause ROS to form, from sources such as drought, air pollutants, UV light, cold temperatures, and external chemicals. An organic example of ROS being formed is during the beta oxidation of fatty acids, or photorespiration in photosynthetic organisms. Aerobic organisms who produce energy through the electron transport chain in mitochondria produce ROS as a byproduct. ROS damage commmonly includes DNA damage, lipid peroxidation, oxidation of amino acids in proteins, and oxidatively inactivating enzymes by oxidation of cofactors. Most aerobic organisms have adapted to this dangerous condition of life, and have a system of enzymes and scavenging free radicals. Enzymes such as are essential for defense against ROS, and include superoxide dismutases (SODs) and hydroperoxidase (CAT). Superoxide dismutases are the primary method of disposal of ROS, and convert superoxide radicals to hydrogen peroxide and water. Catalase attacks the hydrogen peroxide produced by SODs, and converts it into oxygen and water. In skin cells, 5,6 dihydroxyindole-2-carboxylic acid oxidase in the melanosome membranes breaks down hydrogen peroxide into water and oxygen.
