一般說明
Recombinant, human 5-Lipoxygenase expressed in S. fruigiperda insect cells using a baculovirus overexpression system. 5-LO catalyzes the formation of 5(S)-HpETE from arachidonic acid and its subsequent conversion to leukotriene A4. It is localized in the cytosol of resting human and rat peripheral blood neutrophils, whereas it is found in the nucleus in rat basophilic leukemia cells and human alveolar macrophages. Upon stimulation of the cell, 5-LO translocates to the nuclear membrane where it is found in association with 5-LO activating protein (FLAP) and with the 85 kDa cPLA2.

單位定義
One unit is defined as the amount of enzyme that consumes 1.0 nmol of oxygen per min at 25°C in 50 mM Tris-HCl, 100 µM arachidonate, 2 mM CaCl₂, 1 mM ATP, 250 µM oxygen. Oxygen consumption can be measured using a oxygraph equipped with a Clark oxygen electrode.

Natural metabolites with their specific bioactivities are being considered as a potential source of materials for pharmacological studies. In this study, we successfully isolated and identified five known clerodane diterpenes, namely 16-oxo-cleroda-3,13(14)E-dien-15-oic acid (1), 16-hydroxy-cleroda-3,13-dien-15-oic acid (2), 16-hydroxy-cleroda-4(18),13-dien-16,15-olide (3), 3α,16α-dihydroxy-cleroda-4(18),13(14)Z-dien-15,16-olide

Background. The current study aims to give a scientific origin for employing Habenaria plantaginea Lindl. as a potential candidate against nociception, inflammation, and pyrexia. The pharmacological studies were performed on crude extract and subfractions. In the gas chromatography-mass spectroscopy analysis
