PHORBOL Chemical Properties, Uses, Production
Description
Phorbol is a diterpene originally isolated from croton oil. It is used as a starting material for the semisynthesis of various phorbol diesters, which are structurally analogous to diacylglycerol and activate PKC isoforms by associating with their C1 domains.
Uses
Phorbol is a plant-derived diterpene that exhibits various biological activities such as its role as tumor promoters through the activation of protein kinase C.
Definition
ChEBI: A diterpenoid with the structure of tigliane hydroxylated at C-4, -9, -12(beta), -13 and -20, with an oxo group at C-3 and unsaturation at the 1- and 6-positions.
Preparation
Phorbol can be extracted from croton oil by two-phase alcoholysis and purified by high-speed counter-current chromatography[1]. The specific method is as follows:
The optimized operation conditions of biphasic alcoholysis were a reaction time of 91 min, a temperature of 14°C, and a croton oil-methanol ratio of 1:30 (g:ml). The phorbol during the biphasic alcoholysis was 3.2-fold higher in content than that obtained in conventional monophasic alcoholysis. The optimized high-speed countercurrent chromatography method was using the ethyl acetate/n-butyl alcohol/water at 4.7:0.3:5 (v:v:v) with Na2SO4 at 0.36 g/10 ml as the solvent system, using the mobile phase flow rate of 2 ml/min, the revolution of 800 r/min, under which the retention of the stationary phase was achieved at 72.83%. The crystallized phorbol following high-speed countercurrent chromatography was obtained as high purity of 94%.
General Description
White solid.
Air & Water Reactions
Water soluble.
Reactivity Profile
PHORBOL is unstable to prolonged exposure to air, light and ambient temperatures. PHORBOL is also sensitive to acid and alkalis and is subject to autooxidation. PHORBOL dissolves slowly, therefore solution in a desired solvent is best accomplished by prolonged shaking under an inert atmosphere. .
Fire Hazard
PHORBOL is probably combustible.
Toxicology
Toxicity of Phorbol: Dermal (mouse) LD50: 36 mg - mild, Unlike its diesters, phorbol does not appear to be a co-carcinogen or to enhance chemical mutagenesis. Evidence of carcinogenicity is limited. Highly toxic by inhalation, in contact with skin and if swallowed. Irritating to eyes, respiratory system and skin.
