4-Hydroxyamphetamine (4-HA) is a bioactive metabolite of amphetamine. This sympathomimetic is an agonist of the trace amine-associated receptor 1 (EC50 = ~0.2 μM in HEK293 cells expressing rat TAAR1). As a 1% ophthalmologic solution, 4-HA has been used to dilate the pupil in the diagnosis of Horner's syndrome. This product is intended only for forensic and research purposes.

Metabolism of the recently encountered designer drug, methylone, in humans and rats
Xenobiotica 2006 Aug;36(8):709-23.PMID:16891251DOI:10.1080/00498250600780191.
The urinary metabolites of methylone in humans and rats were investigated by analysing urine specimens from its abuser and after administrating to rats with gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-electrospray ionization mass spectrometry (LC-ESI MS), using authentic standards. The time-course excretion profiles of methylone and its three metabolites in rats were further investigated after a single intraperitoneal dosing of 5 mg kg-1 methylone hydrochloride. Two major metabolic pathways were revealed for both humans and rats as follows: (1) side-chain degradation by N-demethylation to the corresponding primary amine methylenedioxycathinone (MDC), partly conjugated; and (2) demethylenation followed by O-methylation of either a 3- or 4-OH group on the benzene ring to produce 4-hydroxy-3-methoxymethcathinone (HMMC) or 3-hydroxy-4-methoxymethcathinone (3-OH-4-MeO-MC), respectively, mostly conjugated. Of these metabolites, HMMC was the most abundant in humans and rats. The cumulative amount of urinary HMMC excreted within the first 48 h in rats was approximately 26% of the dose, and the amount of the parent methylone was not more than 3%. These results demonstrate that the analysis of HMMC will be indispensable for proof of the use of methylone in forensic urinalysis.
Stereospecific analysis of ecstasy-like N-ethyl-3,4-methylenedioxyamphetamine and its metabolites in humans
J Chromatogr B Biomed Sci Appl 2001 Feb 10;751(1):9-18.PMID:11232860DOI:10.1016/s0378-4347(00)00404-7.
A chiral HPLC method has been developed for the ecstasy analogue (R,S)-N-ethyl-3,4-methylenedioxyamphetamine (MDE) and its metabolites o-glucuronyl-(R,S)-N-ethyl-4-hydroxy-3-methoxyamphetamine (HME) and (R,S)-3,4-methylenedioxyamphetamine (MDA) in human plasma. The chiral discrimination of the compounds was carried out with an enantioselective HPLC method using beta-cyclodextrin in the mobile phase for MDE and MDA and a chiral protein phase (chiral-CBH) for HME. MDE and MDA were detected fluorimetrically at 322 nm, while the major metabolite HME was selectively determined by electrochemical detection at +600 mV. After hydrolysis of the conjugates using beta-glucuronidase/arylsulfatase and solid-phase extraction with a cation-exchange phase for sample preparation high recovery rates of more than 95% were yielded. The limit of quantitation for the enantiomers of MDE and its metabolites in plasma were between 1.2 (MDA) and 16 ng/ml (HME) and the relative method standard deviations (V(xO), Table 1) were less than 3%. The methods described have been used successfully in the enantioselective quantitation of the compounds in plasma samples obtained from six healthy volunteers in a clinical study after oral administration of 140 mg racemic MDE hydrochloride. Significant differences were found in the plasma concentrations of the examined stereoisomers. Whereas the R-enantiomer of the parent substance, MDE, was predominant in the plasma samples investigated, higher plasma concentrations of the S-enantiomers of the metabolites MDA and HME were measured.
