Harmalol, a harmala (β-carboline) alkaloid, is a monoamine oxidase inhibitor (MAOi) useful for studies involving melanogenesis. Harmalol is use in β-carboline nucleic acid (DNA and RNA) binding studies.
Beta-carboline alkaloids including harmalol, harmaline, norharmane, harmol, harmine and harmane are important constituents of the medicinal plant, Perganum harmala L. (Zygophylaceae), which has been used in traditional medicine. In the present study, the antiplatelet activities of six beta-carboline alkaloid compounds
The ionization and UV-visible spectral properties of some harmala alkaloids have been investigated spectrophotometrically. Harmaline and harmine were found to have pKa values of 9.55 +/- 0.04 and 7.45 +/- 0.03, respectively. The ionization of harmalol was characterized by two

The present study elucidated the protective effect of beta-carbolines (harmaline, harmalol and harmine) against oxidative damage of brain mitochondria, synaptosomes and PC12 cells induced by either dopamine or 6-hydroxydopamine. Harmaline, harmalol and antioxidant enzymes (superoxide dismutase/SOD and catalase) decreased the

Several beta-carboline (9H-pyrido-[3,4-b]-indole) alkaloids were evaluated for in vitro trypanosomicidal activity against Trypanosoma cruzi epimastigotes belonging to two different strains (Tulahuén and LQ) showing different sensitivity to nifurtimox. Important differences were observed in the susceptibility of the parasites to these
Journal of inorganic biochemistry, 38(1), 47-56 (1990-01-01)
The preparation of novel biologically active platinum(II) and palladium(II) complexes of some beta-carboline alkaloids (harmaline, harmalol, harmine, and harmane) is described. These complexes, characterized on the basis of their CHN elemental analysis, infrared, Raman and 1H and 13C nuclear resonance
