Angiotensin-converting-enzyme inhibitors are a class of medication used primarily for the treatment of high blood pressure and heart failure. They work by causing relaxation of blood vessels as well as a decrease in blood volume, which leads to lower blood pressure and decreased oxygen demand from the heart.
The renin–angiotensin system (RAS), or renin–angiotensin–aldosterone system (RAAS), is a hormone system that regulates blood pressure, fluid and electrolyte balance, and systemic vascular resistance.
Bradykinin (BK) is a peptide that promotes inflammation. It causes arterioles to dilate (enlarge) via the release of prostacyclin, nitric oxide, and endothelium-derived hyperpolarizing factor and makes veins constrict, via prostaglandin F2, thereby leading to leakage into capillary beds, due to the increased pressure in the capillaries. Bradykinin is a physiologically and pharmacologically active peptide of the kinin group of proteins, consisting of nine amino acids.
Captopril, sold under the brand name Capoten among others, is an angiotensin-converting enzyme (ACE) inhibitor used for the treatment of hypertension and some types of congestive heart failure. Captopril was the first oral ACE inhibitor found for the treatment of hypertension. It does not cause fatigue as associated with beta-blockers. Due to the adverse drug event of causing hyperkalemia, as seen with most ACE Inhibitors, the medication is usually paired with a diuretic.
Angiotensin-converting enzyme, or ACE, is a central component of the renin–angiotensin system (RAS), which controls blood pressure by regulating the volume of fluids in the body. It converts the hormone angiotensin I to the active vasoconstrictor angiotensin II. Therefore, ACE indirectly increases blood pressure by causing blood vessels to constrict. ACE inhibitors are widely used as pharmaceutical drugs for treatment of cardiovascular diseases.
Lisinopril is a medication of the angiotensin-converting enzyme (ACE) inhibitor and is used to treat high blood pressure, heart failure, and after heart attacks. For high blood pressure it is usually a first-line treatment. It is also used to prevent kidney problems in people with diabetes mellitus. Lisinopril is taken by mouth. Full effect may take up to four weeks to occur.
Maurício Oscar da Rocha e Silva was a Brazilian physician, biomedical scientist and pharmacologist. He discovered bradykinin, an endogenous polypeptide involved in the physiology, pharmacology and pathology of blood pressure control and many other phenomena related to the contraction of smooth muscles.
Sérgio Henrique Ferreira was a Brazilian physician and pharmacologist noted for the discovery of the bradykinin potentiating factor, which led to new and widely used anti-hypertension drugs — the ACE inhibitors.
Gastão Rosenfeld, was a Brazilian physician and biomedical scientist, one of the co-discoverers of bradykinin, together with Maurício Rocha e Silva and Wilson Teixeira Beraldo, in 1949.
Miguel Angel Ondetti was an Argentine-born American chemist who first synthesized captopril, the first ACE inhibitor that was used to treat heart disease. With his co-worker, David Cushman, he won the 1999 Lasker Award for: "developing an innovative approach to drug design based on protein structure and using it to create the ACE inhibitors, powerful oral agents for the treatment of high blood pressure, heart failure, and diabetic kidney disease".
The bradykinin receptor family is a group of G-protein coupled receptors whose principal ligand is the protein bradykinin.
Bothrops jararaca — known as the jararaca or yarara — is a highly venomous pit viper species endemic to South America in southern Brazil, Paraguay, and northern Argentina. The specific name, jararaca, is derived from the Tupi words yarará and ca, which mean "large snake". Within its geographic range, it is often abundant and is an important cause of snakebite. No subspecies are currently recognized.
David Cushman was born in Indianapolis, Indiana. He was the son of Wayne B. and Mildred M. and married to Linda L. Kranch. They have two children together named Michael and Laura Cushman. Dr. Cushman was an American chemist who co-invented captopril, the first of the ACE inhibitors used in the treatment of cardiovascular disease. With Miguel A. Ondetti, he won the 1999 Lasker Award for: "developing an innovative approach to drug design based on protein structure and using it to create the ACE inhibitors, powerful oral agents for the treatment of high blood pressure, heart failure, and diabetic kidney disease."
Omapatrilat is an experimental antihypertensive agent that was never marketed. It inhibits both neprilysin and angiotensin-converting enzyme (ACE). NEP inhibition results in elevated natriuretic peptide levels, promoting natriuresis, diuresis, vasodilation, and reductions in preload and ventricular remodeling.
Lewis Joel Greene is an American Brazilian biochemist, scientist, university professor and editor of the Brazilian Journal of Medical and Biological Research.
Bradykinin receptor B2 is a G-protein coupled receptor for bradykinin, encoded by the BDKRB2 gene in humans.
The discovery of an orally inactive peptide from snake venom established the important role of angiotensin converting enzyme (ACE) inhibitors in regulating blood pressure. This led to the development of Captopril, the first ACE inhibitor. When the adverse effects of Captopril became apparent new derivates were designed. Then after the discovery of two active sites of ACE: N-domain and C-domain, the development of domain-specific ACE inhibitors began.
Moexipril an angiotensin converting enzyme inhibitor used for the treatment of hypertension and congestive heart failure. Moexipril can be administered alone or with other antihypertensives or diuretics.
Sacubitril is an antihypertensive drug used in combination with valsartan. The combination drug sacubitril/valsartan, known during trials as LCZ696 and marketed under the brand name Entresto, is a treatment for heart failure. It was approved under the FDA's priority review process for use in heart failure on July 7, 2015.
Venom in medicine is the medicinal use of venoms for therapeutic benefit in treating diseases.
