histamine
[no description available] | 2.41 | 2 | 0 | aralkylamino compound;
imidazoles | human metabolite;
mouse metabolite;
neurotransmitter |
astemizole
Astemizole: Antihistamine drug now withdrawn from the market in many countries because of rare but potentially fatal side effects.. astemizole : A piperidine compound having a 2-(4-methoxyphenyl)ethyl group at the 1-position and an N-[(4-fluorobenzyl)benzimidazol-2-yl]amino group at the 4-position. | 1.99 | 1 | 0 | benzimidazoles;
piperidines | anti-allergic agent;
anticoronaviral agent;
H1-receptor antagonist |
betahistine
Betahistine: A histamine analog and H1 receptor agonist that serves as a vasodilator. It is used in MENIERE DISEASE and in vascular headaches but may exacerbate bronchial asthma and peptic ulcers.. betahistine : An aminoalkylpyridine that is pyridine substituted by a 2-(methylamino)ethyl group at position 2. It acts as a histamine agonist and a vasodilator, and is thought to improve the microcirculation of the labyrinth, resulting in reduced endolymphatic pressure. It is used (generally as the hydrochloride or mesylate salt) to reduce the symptoms of vertigo, tinnitus, and hearing loss associated with Meniere's disease. | 2 | 1 | 0 | aminoalkylpyridine;
secondary amino compound | H1-receptor agonist;
vasodilator agent |
clobenpropit
clobenpropit: histamine H3 receptor antagonist. clobenpropit : An imidothiocarbamic ester that consists of isothiourea bearing S-3-(imidazol-4-yl)propyl and N-4-chlorobenzyl substituents. An extremely potent histamine H3 antagonist/inverse agonist (pA2 = 9.93). Also displays partial agonist activity at H4 receptors; induces eosinophil shape change with an EC50 of 3 nM. | 2.4 | 2 | 0 | imidazoles;
imidothiocarbamic ester;
organochlorine compound | H3-receptor antagonist;
H4-receptor agonist |
tele-methylhistamine
tele-methylhistamine: histamine methyltransferase antagonist. N(tele)-methylhistamine : A primary amino compound that is the N(tele)-methyl derivative of histamine. | 2 | 1 | 0 | imidazoles;
primary amino compound | human metabolite;
mouse metabolite |
pargyline
Pargyline: A monoamine oxidase inhibitor with antihypertensive properties. | 2 | 1 | 0 | aromatic amine | |
kainic acid
Kainic Acid: (2S-(2 alpha,3 beta,4 beta))-2-Carboxy-4-(1-methylethenyl)-3-pyrrolidineacetic acid. Ascaricide obtained from the red alga Digenea simplex. It is a potent excitatory amino acid agonist at some types of excitatory amino acid receptors and has been used to discriminate among receptor types. Like many excitatory amino acid agonists it can cause neurotoxicity and has been used experimentally for that purpose. | 2 | 1 | 0 | dicarboxylic acid;
L-proline derivative;
non-proteinogenic L-alpha-amino acid;
pyrrolidinecarboxylic acid | antinematodal drug;
excitatory amino acid agonist |
3-methylhistamine
3-methylhistamine: RN given refers to parent cpd | 1.99 | 1 | 0 | | |
thiourea
Thiourea: A photographic fixative used also in the manufacture of resins. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), this substance may reasonably be anticipated to be a carcinogen (Merck Index, 9th ed). Many of its derivatives are ANTITHYROID AGENTS and/or FREE RADICAL SCAVENGERS.. thiourea : The simplest member of the thiourea class, consisting of urea with the oxygen atom substituted by sulfur. | 2 | 1 | 0 | one-carbon compound;
thioureas;
ureas | antioxidant;
chromophore |
thioperamide
thioperamide: structure given in first source; histamine H3 receptor antagonist | 2.4 | 2 | 0 | primary aliphatic amine | |
