Title: Carcinostatic agent
Inventor: SHINPO KUNIHIRO
IPC: A61K36/02
Filed: 1984-09-13
Abstract: PURPOSE:A carcinostatic agent that is separated from a green fine algae such as Chlorella and has a specific molecular weight, isoelectric point, glycoprotein ratio and protein helix content, has glycoprotein hydrolyzed with alpha-amylase, thus showing high antitumor activity. CONSTITUTION:The objective carcinostatic agent is separated from a green fine algae such as Chlorella, Scenedesmus or Spirulina and is obtained by hydrolyzing the glycoprotein having a molecular weight of 121,000. isoelectric point in pH: 8.6; glycoside/protein ratio: about 1:1; protein helix content: about 19%, with alpha-amylase. The resultant agent shows higher antitumor activity in vivo than the glycoprotein untreated with an enzyme. It can be thought that the glycoprotein has a masked activity, because glycosides entangle around the molecule, but the hydrolysis with alpha-amylase removes the entangling glycoside chains to allow the active sites of the glycoprotein to expose to the substrates.
