ChEBI Name suramin
Definition A member of the class of phenylureas that is urea in which each of the amino groups has been substituted by a 3-({2-methyl-5-[(4,6,8-trisulfo-1-naphthyl)carbamoyl]phenyl}carbamoyl)phenyl group. An activator of both the rabbit skeletal muscle RyR1 and sheep cardiac RyR2 isoform ryanodine receptor channels, it has been used for the treatment of human African trypanosomiasis for over 100 years.

Roles Classification
Biological Role(s): ryanodine receptor agonist
A ryanodine receptor modulator which activates the receptor. Ryanodine receptors (RyRs) act as selective ion channels, modulating the release of calcium. Activating the receptors causes the release of calcium, so depleting internal calcium and ultimately preventing further muscle contraction.
GABA-gated chloride channel antagonist

GABA antagonist
A compound that inhibits the action of gamma-aminobutyric acid.
apoptosis inhibitor
Any substance that inhibits the process of apoptosis (programmed cell death) in multi-celled organisms.
purinergic receptor P2 antagonist
An antagonist at purinergic P2 receptors
EC (protein kinase C) inhibitor
An EC 2.7.11.* (protein-serine/threonine kinase) inhibitor that interferes with the action of protein kinase C (EC
trypanocidal drug
A drug used to treat or prevent infections caused by protozoal organisms belonging to the suborder Trypanosomatida.
Application(s): GABA antagonist
A compound that inhibits the action of gamma-aminobutyric acid.
antineoplastic agent
A substance that inhibits or prevents the proliferation of neoplasms.
angiogenesis inhibitor
An agent and endogenous substances that antagonize or inhibit the development of new blood vessels.
antinematodal drug
A substance used in the treatment or control of nematode infestations.
trypanocidal drug
A drug used to treat or prevent infections caused by protozoal organisms belonging to the suborder Trypanosomatida.
