• 説明

  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.

• 使用

  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.

• 製造方法

  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%.
  

• 定義

  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.

• 一般的な説明

  White solid.

• 空気と水の反応

  Water soluble.

• 反応プロフィール

  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. .

• 火災危険

  PHORBOL is probably combustible.
