Antalarmin
Antalarmin (CP-156,181) is a drug that acts as a CRH1 antagonist. Corticotropin-releasing hormone (CRH), also known as Corticotropin-releasing factor, is an endogenous peptide hormone released in response to various triggers such as chronic stress and drug addiction. Such triggers result in the release of corticotropin (ACTH), another hormone involved in the physiological response to stress. Chronic release of CRH and ACTH is believed to be directly or indirectly involved in many of the harmful physiological effects of chronic stress, such as excessive glucocorticoid release, stomach ulcers, anxiety, diabetes mellitus, osteoporosis, depression, and development of high blood pressure and consequent cardiovascular problems. Antalarmin is a non-peptide drug that blocks the CRH1 receptor, and, as a consequence, reduces the release of ACTH in response to chronic stress. This has been demonstrated in animals to reduce the behavioral responses to stressful situations, and it is proposed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pexacerfont
Pexacerfont (INN, previously known as BMS-562,086) is a drug developed by Bristol-Myers Squibb which acts as a CRF1 antagonist. Corticotropin-releasing factor (CRF), also known as corticotropin-releasing hormone, is an endogenous peptide hormone which is released in response to various triggers such as chronic stress. This then triggers the release of corticotropin (ACTH), another hormone which is involved in the physiological response to stress. Chronic release of CRF and ACTH is believed to be directly or indirectly involved in many of the harmful physiological effects of chronic stress, such as excessive glucocorticoid release, diabetes mellitus, osteoporosis, stomach ulcers, anxiety, depression, and development of high blood pressure and consequent cardiovascular problems. Pexacerfont is a recently developed CRF-1 antagonist which was in clinical trials for the treatment of anxiety disorders, and has also been proposed to be useful for the treatment of depression and irrita ...

Corticotropin Releasing Hormone Antagonist
A Corticotropin-releasing hormone antagonist (CRH antagonist) is a specific type of receptor antagonist that blocks the receptor sites for corticotropin-releasing hormone, also known as corticotropin-releasing factor (CRF), which synchronizes the behavioral, endocrine, autonomic, and immune responses to stress by controlling the hypothalamic-pituitary-adrenal axis (HPA axis). CRH antagonists thereby block the consequent secretions of ACTH and cortisol due to stress, among other effects. CRH receptor subtypes There are four subtypes of the CRH receptor known at present, defined as CRF-1, CRF-2a, CRF-2b, and CRF-2g. Three of these receptors are expressed only in the brain: CRF-1 in the cortex and cerebrum, CRF-2a in the lateral septum and hypothalamus, and CRF-2g in the amygdala. CRF-2b is expressed in the choroid plexus and cerebral arterioles in the brain, but is expressed mainly peripherally on the heart and skeletal muscle tissue. Extensive research has shown that overactivity in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Receptor Antagonist
A receptor antagonist is a type of receptor ligand or drug that blocks or dampens a biological response by binding to and blocking a receptor rather than activating it like an agonist. Antagonist drugs interfere in the natural operation of receptor proteins.Pharmacology Guide: In vitro pharmacology: concentration-response curves " '' GlaxoWellcome.'' Retrieved on December 6, 2007. They are sometimes called blockers; examples include alpha blockers, |
Corticotropin Releasing Hormone Receptor 1
Corticotropin-releasing hormone receptor 1 (CRHR1) is a protein, also known as CRF1, with the latter (CRF1) now being the IUPHAR-recommended name. In humans, CRF1 is encoded by the ''CRHR1'' gene at region 17q21.31, beside micrototubule-associated protein tau MAPT. Structure The human CRHR1 gene contains 14 exons over 20 kb of DNA, and its full gene product is a peptide composed of 444 amino acids. Excision of exon 6 yields in the mRNA for the primary functional CRF1, which is a peptide composed of 415 amino acids, arranged in seven hydrophobic alpha-helices. The CRHR1 gene is alternatively spliced into a series of variants. These variants are generated through deletion of one of the 14 exons, which in some cases causes a frame-shift in the open reading frame, and encode corresponding isoforms of CRF1. Though these isoforms have not been identified in native tissues, the mutations of the splice variants of mRNA suggest the existence of alternate CRF receptors, with differen ...

Pfizer
Pfizer Inc. ( ) is an American multinational pharmaceutical and biotechnology corporation headquartered on 42nd Street in Manhattan, New York City. The company was established in 1849 in New York by two German entrepreneurs, Charles Pfizer (1824–1906) and his cousin Charles F. Erhart (1821–1891). Pfizer develops and produces medicines and vaccines for immunology, oncology, cardiology, endocrinology, and neurology. The company has several blockbuster drugs or products that each generate more than billion in annual revenues. In 2020, 52% of the company's revenues came from the United States, 6% came from each of China and Japan, and 36% came from other countries. Pfizer was a component of the Dow Jones Industrial Average stock market index from 2004 to August 2020. The company ranks 64th on the Fortune 500 and 49th on the Forbes Global 2000. History 1849–1950: Early history Pfizer was founded in 1849 by Charles Pfizer and Charles F. Erhart, two cousins who had i ...

Alcoholism
Alcoholism is, broadly, any drinking of alcohol (drug), alcohol that results in significant Mental health, mental or physical health problems. Because there is disagreement on the definition of the word ''alcoholism'', it is not a recognized diagnostic entity. Predominant diagnostic classifications are alcohol use disorder (DSM-5) or alcohol dependence (ICD-11); these are defined in their respective sources. Excessive alcohol use can damage all organ systems, but it particularly affects the brain, heart, liver, pancreas and immune system. Alcoholism can result in mental illness, delirium tremens, Wernicke–Korsakoff syndrome, Heart arrhythmia, irregular heartbeat, an impaired immune response, liver cirrhosis and alcohol and cancer, increased cancer risk. Drinking during pregnancy can result in fetal alcohol spectrum disorders. Women are generally more sensitive than men to the harmful effects of alcohol, primarily due to their smaller body weight, lower capacity to metaboli ...

Anxiolytics
An anxiolytic (; also antipanic or antianxiety agent) is a medication or other intervention that reduces anxiety. This effect is in contrast to anxiogenic agents which increase anxiety. Anxiolytic medications are used for the treatment of anxiety disorders and their related psychological and physical symptoms. Nature of anxiety Anxiety is a naturally-occurring emotion and an innate response of the body to the environmental stimuli. Mild to moderate anxiety would increase level of performance. However, when anxiety levels exceed the tolerability of a person, anxiety disorders may occur. People with anxiety disorders can exhibit fear responses such as defensive behaviors, high levels of alertness and negative emotions, without external stimuli which induce anxiety within an individual. Those with anxiety disorders are also often found to have concurrent psychological disorders, most commonly depression. Anxiety disorders are divided into 6 types in clinical recognition. They are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
