Background:

Pseudolaric Acid B is a diterpene isolated from the root of Pseudolarix kaempferi Gorden (pinaceae), has anti-cancer, antifungal, and antifertile activities, and shows immunosuppressive activity on T lymphocytes[1][2][3]. Pseudolaric Acid B inhibits hepatitis B virus (HBV) secretion through apoptosis and cell cycle arrest. Pseudolaric Acid B induces autophagy[4][5].
