Biological Activity

3-Methyladenine is a selective autophagy and phosphoinositide 3-kinase (PI3K) inhibitor for Vps34 and PI3Kγ with IC50 of 25 and 60 nM, respectively. 3-Methyladenine significantly shortens the duration of nocodazole-induced-prometaphase arrest. 3-Methyladenine inhibits class I and class III PI3K in different temporal patterns. 3-Methyladenine blocks autophagy through its effect on class III phosphatidylinositol 3-kinase (PI3K), the activity of which is required for the nucleation and assembly of the initial phagophore membrane. 3-Methyladenine treatment does not alter the degree of hemorrhage compared with the SAH group.

Results However, RSV/CFZ combination increased levels of LC3-II and p62/SQSTM1. Higher levels of LC3-II could be partially blocked by the autophagy inhibitor 3-MA, but not for p62/SQSTM1

Method IL-37 induces autophagy in SMMC-7721 and Huh-7 cells.
Cell Lines SMMC-7721 and Huh-7 cells
Concentrations 5 mmol/l
Incubation Time
Results The LC3-II/LC3-I ratio was significantly decreased in IL-37/3-MA-co-treated SMMC-7721 and Huh-7 cells and increased in IL-37/CQ-co-treated SMMC-7721 and Huh-7 cell (Fig. 2E and F). Together, these data further indicate that IL-37 induces autophagy in SMMC-7721 and Huh-7 cells.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
