Angiopoietin-2, a natural antagonist for Tie2 that disrupts in vivo angiogenesis.
Science, 1997Angiogenesis is thought to depend on a precise balance of positive and negative regulation. Angiopoietin-1 (Ang1) is an angiogenic factor that signals through the endothelial cell-specific Tie2 receptor tyrosine kinase.

An antagonist decoy receptor and a death domain-containing receptor for TRAIL.
Science, 1997TRAIL, also called Apo2L, is a cytotoxic protein that induces apoptosis of many transformed cell lines but not of normal tissues, even though its death domain-containing receptor, DR4, is expressed on both cell types.

CCR1 (CC Chemokine receptor 1) is a widely studied G protein-coupled receptor target expressed on multiple types of leukocytes. It is implicated in initiating and exacerbating inflammatory conditions and thus is viewed as a good target for autoimmune and inflammatory therapeutic applications. Numerous CCR1 antagonists have been reported.

Expert Opinion on Biological Therapy, 2001
The majority of cancer have an absolute requirement for angiogenesis, the process by which new blood vessels are formed. The most potent angiogenic cytokine is vascular endothelial growth factor (VEGF) and there has been substantial research into the development of VEGF/VEGF receptor (VEGFR) antagonists.

Effects of vasopressin via V1a- and V2-receptors are closely implicated in a variety of water-retaining diseases and cardiovascular diseases, including heart failure, hyponatraemia, hypertension, renal diseases, syndrome of inappropriate antidiuretic hormone secretion, cirrhosis and ocular hypertension.

Letters in Applied Microbiology, 1994
Three groups of substances were identified which inhibit the bactericidal activity of bacitracin. Beside two divalent metals, Mg2+ and Ca2+, and a metabolite with chelating properties, citrate, the most pronounced effect was observed with pyrophosphate. Metals probably prevent access of bacitracin to the lipid carrier whereas metabolites with chelating

Nature, 1969
IF drugs b and c are competitive antagonists of drug a, then it would seem self evident that the addition of c to a system in which b was already present would increase the degree of block. But where the receptors are exposed to the agonist for only a short time there is another possibility. If the first antagonist dissociates from the receptors slowly,

Drugs which interfere with the voltage-activated inward displacement of calcium ions into excitable cells, including those of the myocardium, atrial and ventricular nodes, and smooth muscle cells, have become known as calcium antagonists. These drugs are a heterogeneous group, and differ from one another in chemistry, tissue specificity, potency and ...

Studies of EN-1639A (naltrexone): a new narcotic antagonist.
American Journal of Psychiatry, 2015The narcotic antagonist EN-1639A (naltrexone) was studied in 37 heroin addicts and found to be clinically useful, with a low incidence of side effects, lack of toxicity, high degree of acceptability to the patient, and capacity to antagonize the euphoric
