The Role of CYP2E1 in the Drug Metabolism or Bioactivation in the Brain

Alcoholic steatohepatitis ASH —the inflammation of fatty liver—is caused by chronic alcohol consumption and represents one of the leading chronic liver diseases in Western Countries. Long-term alcohol abstinence reduces this probability and is the prerequisite for liver transplantation—the only effective therapy option at present. Elevated enzymatic activity of cytochrome P 2E1 CYP2E1 is known to be critically responsible for the development of ASH due to excessively high levels of reactive oxygen species ROS during metabolization of ethanol. In this study, we applied a rational drug design concept to develop drug candidates NCE including preclinical studies. A new class of drug candidates was generated successfully.

Cytochrome P450 2E1 and its roles in disease

This class of enzymes is divided up into a number of subcategories, including CYP1, CYP2, and CYP3, which as a group are largely responsible for the breakdown of foreign compounds in mammals. CYP2E1 metabolizes mostly small, polar molecules, including toxic laboratory chemicals such as dimethylformamide , aniline , and halogenated hydrocarbons see table below. While these oxidations are often of benefit to the body, certain carcinogens and toxins are bioactivated by CYP2E1, implicating the enzyme in the onset of hepatotoxicity caused by certain classes of drugs see disease relevance section below. CYP2E1 also plays a role in several important metabolic reactions, including the conversion of ethanol to acetaldehyde and to acetate in humans, [9] where it works alongside alcohol dehydrogenase and aldehyde dehydrogenase. In the conversion sequence of acetyl-CoA to glucose, CYP2E1 transforms acetone via hydroxyacetone acetol into propylene glycol and methylglyoxal , the precursors of pyruvate , acetate and lactate.

Cytochrome P450 2E1: Its Role in Disease and Drug Metabolism

CYP2E1 enzyme is related to nonalcoholic steatohepatitis NASH due to its ability for reactive oxygen species production, which can be influenced by polymorphisms in the gene. The aim of this study was to investigate hepatic levels, activity, and polymorphisms of the CYP2E1 gene to correlate it with clinical and histological features in 48 female obese NASH patients. Subjects were divided into three groups: i normal; ii steatosis; and iii steatohepatitis.

Metrics details. The cytochrome P CYP enzymes are a class of heme-containing enzymes involved in phase I metabolism of a large number of xenobiotics. The CYP family member CYP2E1 metabolises many xenobiotics and pro-carcinogens, it is not just expressed in the liver but also in many other tissues such as the kidney, the lung, the brain, the gastrointestinal tract and the breast tissue. It is induced in several pathological conditions including cancer, obesity, and type II diabetes implying that this enzyme is implicated in other biological processes beyond its role in phase I metabolism.

До нее тоже доходили подобные слухи. Так, может быть, она зря поднимает панику. - Мидж.

 - Нет. Шестиэтажная ракета содрогалась. Стратмор нетвердыми шагами двинулся к дрожащему корпусу и упал на колени, как грешник перед лицом рассерженного божества. Все предпринятые им меры оказались бесполезными. Где-то в самом низу шахты воспламенились процессоры.

Три. Эта последняя цифра достигла Севильи в доли секунды. Три… три… Беккера словно еще раз ударило пулей, выпущенной из пистолета.
