Label	Id	Description
Aminopterin	D000630	[A folic acid derivative used as a rodenticide that has been shown to be teratogenic.]
Pterins	D011622	[Compounds based on 2-amino-4-hydroxypteridine.]
Aminopyridines	D000631	[Pyridines substituted in any position with an amino group. May be hydrogenated, but must retain at least one double bond.]
Aminopyrine	D000632	[A pyrazolone with analgesic, anti-inflammatory, and antipyretic properties but has risk of AGRANULOCYTOSIS. A breath test with 13C-labeled aminopyrine has been used as a non-invasive measure of CYTOCHROME P-450 metabolic activity in LIVER FUNCTION TESTS.]
Aminopyrine N-Demethylase	D000633
Oxidoreductases, N-Demethylating	D010089
Quinolines	D011804
Aminorex	D000635	[An amphetamine-like anorectic agent. It may cause pulmonary hypertension.]
Aminosalicylic Acids	D000636	[A group of 2-hydroxybenzoic acids that can be substituted by amino groups at any of the 3-, 4-, 5-, or 6-positions.]
Salicylates	D012459	[The salts or esters of salicylic acids, or salicylate esters of an organic acid. Some of these have analgesic, antipyretic, and anti-inflammatory activities by inhibiting prostaglandin synthesis.]
Nitrogenous Group Transferases	D019884	[Enzymes that catalyze the transfer of nitrogenous groups, primarily amino groups, from a donor, generally an amino acid, to an acceptor, usually a 2-oxoacid. EC 2.6.]
Amiodarone	D000638	[An antianginal and class III antiarrhythmic drug. It increases the duration of ventricular and atrial muscle action by inhibiting POTASSIUM CHANNELS and VOLTAGE-GATED SODIUM CHANNELS. There is a resulting decrease in heart rate and in vascular resistance.]
Amitriptyline	D000639	[Tricyclic antidepressant with anticholinergic and sedative properties. It appears to prevent the re-uptake of norepinephrine and serotonin at nerve terminals, thus potentiating the action of these neurotransmitters. Amitriptyline also appears to antagonize cholinergic and alpha-1 adrenergic responses to bioactive amines.]
Amitrole	D000640	[A non-selective post-emergence, translocated herbicide. According to the Seventh Annual Report on Carcinogens (PB95-109781, 1994) this substance may reasonably be anticipated to be a carcinogen. (From Merck Index, 12th ed) It is an irreversible inhibitor of CATALASE, and thus impairs activity of peroxisomes.]
Triazoles	D014230
Ammonia	D000641	[A colorless alkaline gas. It is formed in the body during decomposition of organic materials during a large number of metabolically important reactions. Note that the aqueous form of ammonia is referred to as AMMONIUM HYDROXIDE.]
Ammonia-Lyases	D000642	[Enzymes that catalyze the formation of a carbon-carbon double bond by the elimination of AMMONIA. EC 4.3.1.]
Carbon-Nitrogen Lyases	D019759	[Enzymes that catalyze the cleavage of a carbon-nitrogen bond by means other than hydrolysis or oxidation. Subclasses are the AMMONIA-LYASES, the AMIDINE-LYASES, the amine-lyases, and other carbon-nitrogen lyases. EC 4.3.]
Ammonium Chloride	D000643	[An acidifying agent that has expectorant and diuretic effects. Also used in etching and batteries and as a flux in electroplating.]
Ammonium Compounds	D064751	[Inorganic compounds that include a positively charged tetrahedral nitrogen (ammonium ion) as part of their structure. This class of compounds includes a broad variety of simple ammonium salts and derivatives.]
