5-Hydroxyindole-3-acetic acid (54-16-0)
Hydroxyindoleacetic Acid · 5-Hydroxy-3-Indoleacetic Acid · 5 Hydroxyindolamine Acetic Acid
5-Hydroxyindoleacetic acid (5-HIAA) is the main metabolite of serotonin. In chemical analysis of urine samples, 5-HIAA is used to determine serotonin levels in the body.
Hypericin is a naphthodianthrone, an anthraquinone derivative which, together with hyperforin, is one of the principal active constituents of Hypericum (Saint John's wort). Hypericin is believed to act as an antibiotic, antiviral and non-specific kinase inhibitor. Hypericin may inhibit the action of the enzyme dopamine β-hydroxylase, leading to increased dopamine levels, although thus possibly decreasing norepinephrine and epinephrine.
Ginkgotoxin (4'-O-methylpyridoxine) is a neurotoxin naturally occurring in Ginkgo biloba. It is an antivitamin structurally related to vitamin B6 (pyridoxine). It has the capacity to induce epileptic seizures.
3-HYDROXYPICOLINIC ACID (874-24-8)
3-Hydroxy picolinic acid is a picolinic acid derivative and is a member of the pyridine family. It is used as a matrix for nucleotides in MALDI mass spectrometry analyses.
1-HYDROXYPYRENE (63021-84-1, 5315-79-7)
1-Hydroxypyrene is a human metabolite. It can be found in urine of outdoor workers exposed to air pollution.
dichlorofluorescin · monohlorofluorescein · 2',7'-dichlorofluorescin
Dichlorofluorescein (DCF) is an organic dye of the fluorescein family, being substituted at the 2 and 7 positions by chloride. It is used as an indicator for argentometry by Fajans method. It is also used in the cellular antioxidant activity (CAA) assay.
