    Description

    3-Methyladenine is a potent inhibitor of autophagy and PI3K, blocking autophagy through its effect on PI3K, with IC50s of 25 μM and 60 μM for Vps34 and PI3Kγ, respectively.

    IC50 & Target

    IC50: 25 μM (Vps34), 60 μM (PI3Kγ)[1]

    In Vitro

    3-Methyladenine shows slight preference to binds to Vps34 in vitro, with an IC50 of 25 µM for Vps34 as compared with 60 µM for PtdIns3Kγ, and 3-Methyladenine (10 mM) can inhibit all PtdIns3Ks[1]. 3-Methyladenine (3-MA, 5 mM) suppresses autophagy in HeLa cells under both glucose-free conditions and normal conditions. 3-Methyladenine (2.5, 5 or 10 mM) induces caspase-dependent cell death in HeLa cells, and the death occurs independently of the inhibition of autophagy. Moreover, 3-Methyladenine (3-MA, 1 mM) significantly shortens the duration of nocodazole-induced-prometaphase arrest[2].

    In Vivo

    3-Methyladenine (1.5 mg/100 g, i.p.) treatment alleviates sodium taurocholate-induced severe acute pancreatitis (SAP) in rats at both 12 and 24 h. 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-tnduced SAP[3].

    Cell Assay
    [2]

    3-Methyladenine is directly dissolved into the culture medium.

    Cell viability is determined by a trypan blue exclusion assay. Cells are cultured in the medium with 3-Methyladenine. Both adherent and floating cells are collected and suspended in phosphate buffered saline (PBS, pH 7.4) at a final density of 1-2×106/mL. An equal volume of 0.4% trypan blue solution (w/v, in PBS) is added to the cell suspension and mixed thoroughly. After incubation at room temperature for 3 min, cell counting is performed using a hemacytometer. MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Administration
    [3]

    3-methyladenine (0.009 g) is dissolved in the 600 μL double distilled water and then placed in 50°C bath water.

    All rats are fasted for 12 h with free access to water prior to operation. After anesthesia by intraperitoneal (i.p.) injection of 2% sodium pentobarbital (0.25 mL/100 g), they are laid and fixed on the table, routinely shaven, disinfected, and draped. The rat SAP model is induced by 0.1 mL/min speed uniformly retrograde infusion of a freshly prepared 3.5% sodium taurocholate solution (0.1 mL/100 g) into the biliopancreatic duct after laparotomy. Equivalent volume of normal saline solution is substituted for 3.5% sodium taurocholate solution in the sham-operation (SO) control group. The incision is closed with a continuous 3-0-silk suture, and 2 mL/100 g of saline is injected into the back subcutaneously to compensate for the fluid loss. 180 rats are randomly divided into four groups: (1) Acanthopanax treatment group (Aca group, n = 45) where the rats are injected with 0.2% Acanthopanax injection at a dose of 3.5 mg/100 g 3 h after successful modeling via the vena caudalis once, knowing that this dosage is effective; (2) 3-Methyladenine treatment group (3-methyladenine group, n = 45) where the rats are injected with 100 nmol/μL 3-methyladenine solution at a dose of 1.5 mg/100 g 3 h after successful modeling via the intraperitoneal route once, knowing that this dosage is effective; (3) SAP model group (SAP group, n = 45) where these rats receive an equivalent volume of the normal saline instead of Acanthopanax injection 3 h after successful modeling via the vena caudalis once; (4) SO group (control, n = 45) where these rats receive an equivalent volume of the normal saline instead of Acanthopanax injection 3 h after successful sham-operation via the vena caudalis once. The 45 animals in each of the four groups are equally randomized into 3, 12, and 24 h subgroups for postoperative observations[3]. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
