Tyrosine methylester
Tyrosine methylester, also known as Tyrosine methyl ester hydrochloride, (L)-isomer or Tyr-ome, is classified as a tyrosine or a Tyrosine derivative. Tyrosines are compounds containing tyrosine or a derivative thereof resulting from reaction of tyrosine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Tyrosine methylester is considered to be a slightly soluble (in water) and a very weak acidic compound. Tyrosine methylester can be found in humans. KEIO_ID T032 H-Tyr-OMe, an amino acid, is an endogenous metabolite[1].
Metyrosine
Metyrosine is only found in individuals that have used or taken this drug. It is an inhibitor of the enzyme tyrosine 3-monooxygenase, and consequently of the synthesis of catecholamines. It is used to control the symptoms of excessive sympathetic stimulation in patients with pheochromocytoma. (Martindale, The Extra Pharmacopoeia, 30th ed)Metyrosine inhibits tyrosine hydroxylase, which catalyzes the first transformation in catecholamine biosynthesis, i.e., the conversion of tyrosine to dihydroxyphenylalanine (DOPA). Because the first step is also the rate-limiting step, blockade of tyrosine hydroxylase activity results in decreased endogenous levels of catecholamines and their synthesis. This consequently, depletes the levels of the catecholamines dopamine, adrenaline and noradrenaline in the body,usually measured as decreased urinary excretion of catecholamines and their metabolites. One main end result of the catecholamine depletion is a decrease in blood presure.

2-Phenyl-1,3-propanediol monocarbamate
2-Phenyl-1,3-propanediol monocarbamate is a metabolite of felbamate. Felbamate (marketed under the brand name Felbatol by MedPointe) is an anti-epileptic drug used in the treatment of epilepsy. It is used to treat partial seizures (with and without generalization) in adults and partial and generalized seizures associated with Lennox-Gastaut syndrome in children. However, an increased risk of potentially fatal aplastic anemia and/or liver failure limit the drugs usage to severe refractory epilepsy. (Wikipedia)

Methacholine choride acts directly on acetylcholine receptors on smooth muscle causing bronchoconstriction and airway narrowing. Methacholine choride shows a high sensitivity to identify bronchial hyperresponsiveness (BHR). Methacholine choride can be used to measure airway hyperresponsiveness (AHR) as a diagnostic aid in the assessment of individuals with asthma-like symptoms and normal resting expiratory flow rates[1][2][3][4].

N-Acetyldopamine
N-Acetyldopamine also known as NADA is an acetylated form of dopamine. It is an endogenously produced derivative or metabolite of dopamine. It belongs to the family of compounds known as catecholamines and derivatives. These are compounds containing 4-(2-aminoethyl) pyrocatechol [4-(2-aminoethyl) benzene-1,2-diol] or a derivative thereof. While NADA has been found in the human liver, kidney, and urine, it is unclear what its role is in mammal physiology (PMID: 16179545). NADA exists in both free and conjugated (glucuronide) forms. Conjugated NADA accounts for about 90\\\% of the total excretion of NADA. Urinary excretion of total N-acetyldopamine averages 0.485 micromoles/day in healthy humans (PMID: 6513727). The concentration of NADA is thirteen times higher in children with neuroblastoma than in normal subjects (PMID: 1321164). NADA is known to be a sepiapterin reductase inhibitor (PMID: 16179545). N-acetyldopamine has been shown to inhibit lipopolysaccharide-induced lipid peroxidation in rat brains (PMID: 16179545). N-acetyldopamine (NADA) is a catecholamine that is used by insects as sclerotizing precursors to harden their cuticle[1].
