3-Methyladenine (3-MA) is a PI3K inhibitor. 3-Methyladenine is a widely used inhibitor of autophagy via its inhibitory effect on class III PI3K.
体外研究
3-Methyladenine (0-10 mM; 0-48 hours) induces caspase-dependent cell death in HeLa cells in a time-and dose-dependent manner.
3-Methyladenine (5 mM; 24 hours) suppresses autophagy in HeLa cells under both glucose-free conditions and normal conditions.
3-Methyladenine (5 mM; 0-48 hours) suppresses conversion of LC3-I to LC3-II (autophagy markers) between 12hours and 48 hours, confirms the inhibitory effects on autophagy.
3-Methyladenine induces cell death is independent of autophagy inhibition.
3-Methyladenine significantly shortens the duration of nocodazole-induced-prometaphase arrest.
Note:
在体外细胞培养实验中,3-MA 常用的浓度为 0.5-10 mM,所以优先推荐直接称取本次实验所需粉末量,用培养基完全溶解,0.22 μm 过滤器过滤除菌之后使用。建议溶液现配现用,尽快用完。

体内研究
3-Methyladenine (1.5 mg/100 g; intraperitoneal injection; 3-24 hours) treatment alleviates sodium taurocholate-induced severe acute pancreatitis (SAP) in rats at both 12 hours and 24 hours.
3-Methyladenine inhibits autophagy of pancreatic acinar cells in sodium taurocholate-tnduced SAP.
3-Methyladenine also shows inhibitory effects on PI3K/Akt signaling pathway and NF-κB signaling pathway in sodium taurocholate-induced SAP.

Dosage:
1.5 mg/100 g (1000 μM)
Administration:
Intraperitoneal injection
Result:
Alleviated Sodium Taurocholate-Induced SAP.
