1-methyl-3-isobutylxanthine
1-Methyl-3-isobutylxanthine: A potent cyclic nucleotide phosphodiesterase inhibitor; due to this action, the compound increases cyclic AMP and cyclic GMP in tissue and thereby activates CYCLIC NUCLEOTIDE-REGULATED PROTEIN KINASES. 3-isobutyl-1-methylxanthine : An oxopurine that is xanthine which is substituted at positions 1 and 3 by methyl and isobutyl groups, respectively. | 1.97 | 1 | 0 | 3-isobutyl-1-methylxanthine | |

nitrile;
pyridone | cardiotonic drug;
EC 3.1.4.17 (3',5'-cyclic-nucleotide phosphodiesterase) inhibitor;
platelet aggregation inhibitor;
vasodilator agent |
pentobarbital
Pentobarbital: A short-acting barbiturate that is effective as a sedative and hypnotic (but not as an anti-anxiety) agent and is usually given orally. It is prescribed more frequently for sleep induction than for sedation but, like similar agents, may lose its effectiveness by the second week of continued administration. (From AMA Drug Evaluations Annual, 1994, p236). pentobarbital : A member of the class of barbiturates, the structure of which is that of barbituric acid substituted at C-5 by ethyl and sec-pentyl groups. | 1.97 | 1 | 0 | barbiturates | GABAA receptor agonist |
propranolol
Propranolol: A widely used non-cardioselective beta-adrenergic antagonist. Propranolol has been used for MYOCARDIAL INFARCTION; ARRHYTHMIA; ANGINA PECTORIS; HYPERTENSION; HYPERTHYROIDISM; MIGRAINE; PHEOCHROMOCYTOMA; and ANXIETY but adverse effects instigate replacement by newer drugs.. propranolol : A propanolamine that is propan-2-ol substituted by a propan-2-ylamino group at position 1 and a naphthalen-1-yloxy group at position 3. | 1.97 | 1 | 0 | naphthalenes;

secondary amine | anti-arrhythmia drug;
antihypertensive agent;
anxiolytic drug;
beta-adrenergic antagonist;
environmental contaminant;
human blood serum metabolite;
vasodilator agent;
xenobiotic |
reserpine
Reserpine: An alkaloid found in the roots of Rauwolfia serpentina and R. vomitoria. Reserpine inhibits the uptake of norepinephrine into storage vesicles resulting in depletion of catecholamines and serotonin from central and peripheral axon terminals. It has been used as an antihypertensive and an antipsychotic as well as a research tool, but its adverse effects limit its clinical use.. reserpine : An alkaloid found in the roots of Rauwolfia serpentina and R. vomitoria. | 1.97 | 1 | 0 | alkaloid ester;

carbachol
Carbachol: A slowly hydrolyzed CHOLINERGIC AGONIST that acts at both MUSCARINIC RECEPTORS and NICOTINIC RECEPTORS. | 1.97 | 1 | 0 | ammonium salt;
carbamate ester | cardiotonic drug;
miotic;
muscarinic agonist;
nicotinic acetylcholine receptor agonist;
non-narcotic analgesic |
dobutamine
Dobutamine: A catecholamine derivative with specificity for BETA-1 ADRENERGIC RECEPTORS. It is commonly used as a cardiotonic agent after CARDIAC SURGERY and during DOBUTAMINE STRESS ECHOCARDIOGRAPHY.. dobutamine : A catecholamine that is 4-(3-aminobutyl)phenol in which one of the hydrogens attached to the nitrogen is substituted by a 2-(3,4-dihydroxyphenyl)ethyl group. A beta1-adrenergic receptor agonist that has cardiac stimulant action without evoking vasoconstriction or tachycardia, it is used as the hydrochloride to increase the contractility of the heart in the management of acute heart failure. | 3.77 | 2 | 1 | catecholamine;
secondary amine | beta-adrenergic agonist;
cardiotonic drug;
sympathomimetic agent |
cyclic gmp
Cyclic GMP: Guanosine cyclic 3',5'-(hydrogen phosphate). A guanine nucleotide containing one phosphate group which is esterified to the sugar moiety in both the 3'- and 5'-positions. It is a cellular regulatory agent and has been described as a second messenger. Its levels increase in response to a variety of hormones, including acetylcholine, insulin, and oxytocin and it has been found to activate specific protein kinases. (From Merck Index, 11th ed). 3',5'-cyclic GMP : A 3',5'-cyclic purine nucleotide in which the purine nucleobase is specified as guanidine. | 1.97 | 1 | 0 | 3',5'-cyclic purine nucleotide;
