Thrombin is a serine protease, an enzyme that, in humans, is encoded by the F2 gene. Prothrombin is proteolytically cleaved to form thrombin in the clotting process. Thrombin in turn acts as a serine protease that converts soluble fibrinogen into insoluble strands of fibrin, as well as catalyzing many other coagulation-related reactions.
Low-molecular-weight heparin (LMWH) is a class of anticoagulant medications. They are used in the prevention of blood clots and treatment of venous thromboembolism and in the treatment of myocardial infarction.
An international nonproprietary name (INN) is an official generic and non-proprietary name given to a pharmaceutical drug or an active ingredient. INNs are intended to make communication more precise by providing a unique standard name for each active ingredient, to avoid prescribing errors. The INN system has been coordinated by the World Health Organization (WHO) since 1953.
Cerivastatin is a synthetic member of the class of statins used to lower cholesterol and prevent cardiovascular disease. It was marketed by the pharmaceutical company Bayer A.G. in the late 1990s, competing with Pfizer's highly successful atorvastatin (Lipitor). Cerivastatin was voluntarily withdrawn from the market worldwide in 2001, due to reports of fatal rhabdomyolysis.
Kininogens are precursor proteins for kinins, biologically active polypeptides involved in blood coagulation, vasodilation, smooth muscle contraction, inflammatory regulation, and the regulation of the cardiovascular and renal systems.
Batroxobin, also known as reptilase, is a snake venom enzyme with Venombin A activity produced by Bothrops atrox and Bothrops moojeni, venomous species of pit viper found east of the Andes in South America. It is a hemotoxin which acts as a serine protease similarly to thrombin, and has been the subject of many medical studies as a replacement of thrombin. Different enzymes, isolated from different species of Bothrops, have been called batroxobin, but unless stated otherwise, this article covers the batroxobin produced by B. moojeni, as this is the most studied variety.
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.
Ecarin clotting time (ECT) is a laboratory test used to monitor anticoagulation during treatment with hirudin, an anticoagulant medication which was originally isolated from leech saliva. Ecarin, the primary reagent in this assay, is derived from the venom of the saw-scaled viper, Echis carinatus.
Cilofungin (INN) is the first clinically applied member of the echinocandin family of antifungal drugs. It was derived from a fungus in the genus Aspergillus. It accomplishes this by interfering with an invading fungus' ability to synthesize the cell wall.
Sergliflozin etabonate is an investigational anti-diabetic drug being developed by GlaxoSmithKline. It did not undergo further development after phase II.
Azalanstat is an anti-obesity drug acting as a lanosterol 14α-demethylase inhibitor.
Terbogrel (INN) is an experimental drug that has been studied for its potential to prevent the vasoconstricting and platelet-aggregating action of thromboxanes. Terbogrel is an orally available thromboxane A2 receptor antagonist and a thromboxane A synthase inhibitor. The drug was developed by Boehringer Ingelheim.
Gemopatrilat (INN) is an experimental drug that was never marketed. It acts as a vasopeptidase inhibitor. It inhibits both angiotensin-converting enzyme (ACE) and neutral endopeptidase (neprilysin).
Brigatinib, sold under the brand name Alunbrig among others, is a small-molecule targeted cancer therapy being developed by ARIAD Pharmaceuticals, Inc. Brigatinib acts as both an anaplastic lymphoma kinase (ALK) and epidermal growth factor receptor (EGFR) inhibitor.
Semuloparin is an experimental antithrombotic being developed by Sanofi-Aventis and belongs to the group of low molecular weight heparins (LMWH). It has completed Phase III clinical trials for the prevention of thromboembolism following various kinds of surgery such as hip replacement, as well as for patients undergoing chemotherapy.
Tofogliflozin is an experimental drug for the treatment of diabetes mellitus and is being developed by Chugai Pharma in collaboration with Kowa and Sanofi. It is an inhibitor of subtype 2 sodium-glucose transport protein (SGLT2), which is responsible for at least 90% of the glucose reabsorption in the kidney. As of September 2012, the drug is in Phase III clinical trials.
Lasinavir is an experimental peptidomimetic protease inhibitor researched by Novartis and Bristol-Myers Squibb as a treatment for HIV infection. It was originally discovered by Novartis at Basel (Switzerland). Its investigation was terminated after Phase I on October 09, 2002.
Vanucizumab is an experimental humanized monoclonal antibody designed for the treatment of cancer.
Ceronapril in a phosphonate ACE inhibitor that was never marketed.
Silmitasertib (INN), codenamed CX-4945, is a small-molecule inhibitor of protein kinase CK2, a constitutively active serine/threonine-specific protein kinase that is overexpressed in several types of tumors.
