Patent number: 10682330Abstract: In order to reduce the side effects of paclitaxel derivatives having excellent anti-cancer effects, an attempt was made to produce a liposome encapsulating paclitaxel derivatives such as paclitaxel monoglycosides and docetaxel monoglycosides. However, the introduction efficiency of paclitaxel derivatives, etc., into a liposome was poor, and this technique was not developed to a practical level.
